Hi Scanner Danner! This is this first video I have watched of yours in a while I am ASE Certified in the Electrical Systems of Automobiles, and the way you teach this stuff is so much better then the way my teacher taught this back in college, I love how you go into depth for each step of the process, I am more of a hands on learner, I honestly wish you were my teacher for it when I was in college, I love the video! I am will be subscribing to see more videos of yours!
You should subscribe and watch the premium videos from his classes on his website, scannerdanner.com. Best $10/mo you can spend. You won't find better anywhere on the net. I signed up when it was on YT thinking I'd watch a few during the free trial and then cancel because I'm cheap. I never left and will subscribe indefinitely.
@@ScannerDanner I have a MR2 that is only firing 1 n 4... 2 n 3 are not firing... I have checked and replaced everything and I'm lost... Please help me. Oldschoolj510@gmail.com
I'm sixty two years old. I graduated from automotive school in 2000 and worked in the field for about three years before I moved to Mexico. Some years back I returned to the U.S. and discovered you on TH-cam. I want to thank you for re kindling my passion to work on cars. The other day I took out my scanner, voltmeter and my Sun scope to trouble shoot a TPS problem on my sons truck. It felt like old times.It is great to see you work with your sons. You are a good teacher with a lot of patience. God bless the Danner family!
Hi Scanner, I am a Electronic techinician my self, most experience on machinery not on cars. I have face some hot potatoes jobs on cars and I will say. That you make it see so easy and fun. I respect your skills and knoglege. Yoe explain things so easly. Thanks for the video, it cleared many doubts.
Yoh are a teacher in literally. No fist of master. You powered thousands of people including me. Personally i owe you. Respect you and wish you all the best sir!
One of the things that I love about your videos is you always hammer home the basics such as safety. Years ago my sister couldn't get my dad's International Travelall started. (hey I did say years ago) So I went and looked at it. I took a screwdriver with me under the vehicle and got it to not only crank over but start. I got out from under the car very quickly as it was still in drive. I was lucky that I was very thin at the time and could get out. If I had been a little bigger I would probably have been run over. Safety first and thanks for the reminders.
As a fellow Celica owner, the thorough explanation of how the igniter works with the coil was very interesting! Always wondered how you would diagnose a bad unit! Good info 🖒
I always enjoy watching your videos . Low compression makes me think back to when a fellow I work with told me he was going home and he ran the car into so water . Apparently the engine got some of it . The engine died and no start . So and it had a lot of miles on the engine had low compression. So he was told to pour some motor oil in the carb and let the engine get some of that on the cylinder walls rings ect . The engine started up . I head that once one a engine that had got hot also . I never seen that before . Thanks for all you do
I have never said to myself “you know, that Danner talks way to much”. I find that pretty much everything you say is informative. Even if you’re going over it for the third time. Sometimes I need that third time to finally be like, ohhh i got it now, that’s how that works. Plus it’s cool to see your son catching on too. I hope my son that is soon to be born will like learning this stuff from me
Thanks so much. There are others who feel differently and even commented so in this video but it's comments like yours that remind me to just keep doing my thing. I realize it's not for everyone and that is okay.
scanner danner, you are THE MAN! I have not found any other information on the web/youtube that has been as thorough and helpful as your videos. You have helped me drastically with the diagnosis of my ignition system. I have a 93 4runner with the 3VZE and was getting very stressed out when diagnosing the issue. There is very minimal information related to the 2nd generation 4runner, when it comes to diagnosing, calibrating, and understanding the various components that love to break on this pain in the neck engine. I plan on making some how to videos regarding TPS calibrating and Ignitor diagnosing for the 3VZE. I wanted to show the process of using a test light on the IGT circuit to verify spark at the coil, thus eliminating the condemning of various components that seem to always get replaced leading to no outcome. I of course would give the credit where its due and state all of the information was obtained from your channel. I just wanted to say thank you, and you have helped out many of us 4runner owners who felt left in the dark when it came to ignition gremlins. I am not joking when I say the literal test procedure in the Toyota WorkShopManual for the ignitor is to, "Try another Ignitor."
I just a problem with my 1993 Toyota four runner same engine.just started having crank/no start ...it does have fuel has spark and I even changed the igniter control module.still nothing ,I need you're help ?
At first I was scratching my head when I saw you reach for fuel injectors when you knew it was a spark problem. Of course you were thinking ahead to the next question, the question of whether you had cam and crank signals. It's so much easier to test at the injectors rather than hunting for notoriously difficult cam/crank sensors, and you wanted to prove the slight movement of the tach was not mechanical vibration from the moving engine. By proving injectors were working you proved that cam and crank signals are fine, cutting your work load in half.
I've always enjoyed the detail that you put into your videos. The picture in picture and references to your book keep me involved. There are times I can't watch a video in it's entirety but not here. It was worth the 49 minutes and now can't wait for part two.
Outstanding information! Not over thorough but thorough enough to cover all the information needed to diagnose as well as explained and simplified in manner that is easily understood. Much appreciated.
Always love the case studies. 127,000 of us agree. Also, use of the tools. The test light told u u have your inputs. The amp clamp on the coil primary confirmed it. U could have even used the old Vantage (that u resoldered the battery wire on) with your amp clamp and got a pattern. And premium is great too!!
Amazing video man I'm electrician at a plant makes perfect sense I have 95 t100 2.7 it died on me on thed interstate no spark but now I know what to test ur a great teacher I didn't realize how simple it is on my old worrk truck
Great video. Caleb is really starting to ask good questions. The interaction makes for a really good video. I always enjoy the premium channel diags where you have a couple of your students with you. Keep em coming. I have learned so much!
Thanks Scanner Danner' i have learned a lot of your films. This help me in my career so thank you once again and God always bless you and your family....
thank you for sharing your knowledge ... every time I see a video of these I realize that I still need a lot to learn ... greetings and blessings for you and your family!
This is awesome this help me so much I am so grateful that I found this video the way you explain everything I can actually understand what’s going on during the testing process and it made it so much easier to figure out what was wrong with my car. Keep up the awesome work and have a nice day.
Paul I'm a premium subscriber and have your book love your channel and these types of videos with your son are fantastic. I'm an aircraft mech but these videos with Caleb really brings auto mechanics down to a DIYERS level if you know what I'm trying to say. Really enhances your book and classroom explanations. Very informative and comprehendable. Hope I spelled your sons name correctly. Need to look into the AESwave tool. Would be very helpful as I work alone.❤️ your videos and family interaction.
You did! "Caleb" just like that cool dude in the bible who was with Joshua and said they could take on the Giants haha Don't forget about the links I put in the descriptions of my videos. It has links to the tools you guys are seeking and it helps me out when you use them. Thanks again Arthur!

You are a legend however when it comes to the transistor in series with the coil the base emitter circuit cannot have 5 volts only 7 volts unless there is an emitter resistor keep up the great videos you are the best electronics on the internet
@@ScannerDanner then there would be a base limiting resistor if there is a 5 volt trigger the voltage has to go land somewhere the base to emitter is .7 volts when it's forward bias
@@ScannerDanner my point is I'm sure there are five volt triggers just like digital pulses but you still have to draw the resistor in series with the base
Paul should have an emergency tool kit and get 2 relay testers. One for the garage and the other for road tests. Have a Actron CP9690 code tester to check codes and road tests. Also fuel pressure tester and timing light.
Thanks for talking too much Paul! I've been doing this since the late 80's and never had this kind of detailed explanation of this system. A better understanding of how it works will make for a more confident diagnosis.
I deleted that pinned comment. I should never have gotten involved. That was getting ugly fast and I meant the guy no harm. I actually feel bad now. But thank you for your comment. It really means a lot.
Your welcome Paul. What you're doing is very helpful to a lot of people. Some may disagree but a whole lot more of us are very appreciative of what you do.
Finally got some time to watch. Nice explanation Paul for anyone learning to understand how Toyota ignition systems work. On to part 2, when I get some time. ;-) Take care
Do you have a video for my 2005 PT Cruiser, none turbo , manual. Only have 4 plug in harness. A/c.. it just will not pass smog! They keep telling me to do the drive cycle and did and done numerous times...can you help me out.???
Paul,great video man! 👍 Thanks for taking the time and explaining everything in detail,it’s very much appreciated! I bet Paul knew what’s wrong with this car on experience alone,the minute he realized he had no spark!
Hey man thanks for the video. 1st time watcher and immediate fan. I have a similar model celica that has started having intermittent problems, so at least now I know some more steps I can take when it stops again! I will watch some more of your videos in preparation but I enjoyed learning from the explanations so I think you have a new fan and maybe subscriber! Cheers from down under!
Hi Paul . it is very nice job , but I would like to discuss two points .....1/ the main purpose of IGF is giving feedback to ECM as confirmation that SPARK is already generated .... that means this signal is tied with Secondary NOT primary coil . so, I think that this diagram has something missed and I think that power feeding at time 27:20 is tied with IGF to give feedback signal to ECM that there are other voltage fluctuations on the feed line left after IGT ..... I meant there are two current flows in this line one when IGT and current flow in primary and the second current flow would be before secondary side as I mentioned on 27:20 . I hope if you could make another video as experiment 2nd point is if this secondary coil shorted , the system would completely shifted to Fail- Safe mode or what you call Lamb mode and shut off injectors completely ....... you know in some time .. if there is No Injection Pulse ... you have to look after IGF signal maybe there is shorted in the end , it is very nice video , thank you
The NE signal indicates crankshaft position and engine RPM. The G signal (also called VVT signal) provides cylinder identification. By comparing the G signal to the NE signal, the ECM is able to identify the cylinder on compression.14/09/2022 NE Signal and G Signal - Toyota Engine Control Systems
Toyota Distributor and DLI Ignition Systems - explanation and guide Toyota Single Coil and Distributor Ignition Systems, with computer controlled advance and 5-pin ignition systems So here is a quick little explanation of Toyota ignition system Ignition System Overview This is basically the breakdown of the most common of toyota's ignition systems, where ignition timing is controlled by the ECU and the ignition system comprises of a single coil and distributor. In short, what happens is the dissy is obviously spinning with engine RPM, and generating the variable reluctance (VR) signals "G1" and "Ne". Ne is the cam position signal from the multi-tooth wheel, giving the ECU the exact rotational position of the engine within it's cycle. G1 is a reference signal that the ECU can use to determine what cylinder the engine is up to. The ECU reads these signals, then applies it's ignition advance according to its programmed ignition map, and sends the IGt signal out to the Ignitor. The ignitor fires the ignition coil according to the IGt signal. The ignitor also generates a return signal to the ECU - IGf - to let the ECU know that the ignition event was sucessful. Pretty simple really.
Toyota Distributor and DLI Ignition Systems - explanation and guide Toyota Single Coil and Distributor Ignition Systems, with computer controlled advance and 5-pin ignitor The most common stumbling block people come across with wiring up an engine conversion is the ignition system. Often a second hand loom is used or you are making a loom from scratch, and when you get to the ignition system - you can't for the life of you match up what the fudge is what! So here is a quick little explanation of Toyota ignition system and 5-Pin ignitors that should answer most questions about them. Ignition System Overview This is basically the breakdown of the most common of toyota's ignition systems, where ignition timing is controlled by the ECU and the ignition system comprises of a single coil and distributor. In short, what happens is the dissy is obviously spinning with engine RPM, and generating the variable reluctance (VR) signals "G1" and "Ne". Ne is the cam position signal from the multi-tooth wheel, giving the ECU the exact rotational position of the engine within it's cycle. G1 is a reference signal that the ECU can use to determine what cylinder the engine is up to. The ECU reads these signals, then applies it's ignition advance according to its programmed ignition map, and sends the IGt signal out to the Ignitor. The ignitor fires the ignition coil according to the IGt signal. The ignitor also generates a return signal to the ECU - IGf - to let the ECU know that the ignition event was sucessful. Pretty simple really. So how does one wire up the 5 pin ignitor? The really annoying part about wiring up a conversion, is a majority of Toyota 5 pin ignitors after 1989 have the plug as part of the housing - meaning there are no wire colours to go by. This is quite the PAIN. So here are the pinouts, and most comon wiring colours. Note that the metal case is the earth for the ignitor, so make sure it is bolted to metal (the stock brackets usually provide this earth) 1/ B-R: Coil Negative (output) 2/ B: Tacho signal (output) 3/ B-O: Ignition power (12V+) 4/ W: IGt (input) 5/ W-R: IGf (output) How does one wire this all up with an aftermarket ECU? Well - this is easy! Most of you would be using a Microtech/EMS/etc etc which are all quite capable of using the stock signals and ignition system. Here is the way most of these will hook up to this type of Toyota ignition system..... Most aftermarket ECUs want both a "cam position trigger" and a "reference trigger". The Toyota dissy in this system provides these triggers with a VR (variable reluctance) signal with a falling edge trigger. This "falling edge" part is important, because the ECU needs to have the signal go a particular way for the internal circuitry to detect the very low AC voltage from the VR signal and interpret that as a trigger event. Some aftermarket ECUs allow you to select a falling edge or rising edge trigger through it's programming software, but some want the signal to be one or the other without the option of change.
Excellent teacher, very excellent class, very grateful. I have a problem in a 2006 nissan sentra the car is burning the ignition coils every month. Thank you
The same has burned the factory coils friend. I have reviewed the condeser that brings and is bad. I'll try changing it. Thanks for answering and you help.
thank you very much mr danner please a video how we can check synchroniation between cameshaft and cranckshaft sensors (signals and connections) thanks again .
This video is freaking amazing! It was the final puzzle piece for me to fully understand how the ignition works for my Toyota Corolla :) The distributor is basically the same, but lacks the sensor for the 1 x 360 pulse. But it doesn't need the sensor, because the injectors all fire at the same time. Thank you so much, this helped a lot in my journey to replace the stock ECU :)
WHAT.?? All this time I thought your first name was SCANNER.. Lol Great, Now we're all messed up. Thanks Dan...ner Paul. Oh ya.. Section 18 for the group fire.. Another great video Paul. Thank You Cheers
I always tell guys I'm teaching that IGF stands for (I Got Fire). I actually like to scope the IGF when I have intermittent misfires on coil on plug Toyota's and you can actually see in the pattern what coil is fail/starting to fail.
I have a 2001 Mazda Miata with a 1.8 VVT Engine that cranks but has no spark, also it is missing the fuel injectors. I bought the car like that. the fuel pump works but no spark from either coils.
My old 1992 Civic died on me and did all this test and everything checked good. Had fuel, ignition and spark. Compression sounded good. Turned out distributor shaft bearing was going out and melted the rotor and it hit the cap turning it 90 degrees off. Spark was not firing at the right cylinder.
what a good video master a question that range should have the clamp amperimetrica to be able to make all the measurements in the components of the car I am buying one but I do not know if with a 60 A is enough to make the measurements
Check for oil in the distributor cap. This was pretty common. If it's wet in there, you'll be replacing the distributor. Oil would come in through the shaft, and cause this if it went unnoticed for a while.
On this distributor design, the oil would need to be severe to cause an issue. On optical pick-ups used in Nissan and some GM distributors, the oil would interupt the signals. The real issue with oil, is it shows there is wear in the distributor bushing and this can eventually cause the shaft to wobble and that itself can mess up the input signals.
ScannerDanner Thanks, Paul. I have a 1996 Toyota Corolla with stalling after running smooth for long time. In fact, it won't stall now after an hour. When I change the distributor seal, I'll see how much the distributor shaft wobbles. However, distributor air gap is 0.010 inch, in spec, so it seems distributor bushings not worn. Resistance of cam sensor and crank sensor (cold and hot) at ecm in spec. Resistance of ignition coil primary and secondary (cold and hot) in spec. I can't afford amp probe and scope...
ScannerDanner I can restart immediately. Idles smooth for a few seconds before stalling again. I can tap gas pedal as it stalls to revive engine for another few seconds until it tries to stall again. If engine cools, say 15 minutes, it will idle longer, maybe 10 seconds, before needing to tap gas. However, can't seem to duplicate problem last few months. Ran an hour with no problems recently. Code never thrown.
I couldn't get to the starter S post from the top :-) Great question! Just make sure you use my link when you buy it. You'll pay the same amount either way. I just get a little love from AES when you use my link. Thanks!
The sound of the engine can be to much raw fuel cleaning the piston rings and that's is normal after so many cranking without burning that mix. Good video
Paul have viewed plenty of you videos, find them very interesting and would like to thank you for taking he time to do this as they can be very helpful. In both diagnosing and repairing your own vehicle one question I have is what setting are a good starting point when using an oscilloscope as you may guess I am new to oscilloscopes to test automotive circuits?
Thank you! Scope setting vary greatly with what you are measuring. The best thing for you to do is to keep watching my videos and also my Picoscope basics part 1 and 2. You do not need a picoscope to learn from these. th-cam.com/video/81AGbZcgCZs/w-d-xo.html th-cam.com/video/ntJJYhkmR4I/w-d-xo.html
Hi Paul Thanks for the link videos were very interesting and informative, what is your opinion of the uscope as a first scope, for repairing my own car, any chance you could do some more examples of its capability.
Fortunately I've created ScannerDanner Premium just for guys like you. And my son for that matter. He's starting to watch my classroom lectures now too as a junior in high school. He will be a beast if he keeps this up :-)
Yes he does it in laymens friendly terms. Mr danner your draggin it out. Less yappin sorry. This was 30min video you know that. Last 15 min is the gold too. A lot of guys looking to learn need someone like Mr danner. Oh shit, I'm listening and you just said, "some of you are goin to say i talk to much. Most of you, will say yeah man sweet:) There you go laymen terms, able to please most of the people most of the time, and some of us just have to live with it. Keep up the good work . Those with my thinking have to understand. Mr danner has an agenda as well. If he could speak less he would , if the audience was a different one, Right? Aloha~
Hola.Disculpé mi ignorancia. Mi pregunta es: ? Porque la luz de prueba enciende en ambas terminales del inyector de combustible, una terminal es el positivo y la otra es negativo o el control si no me equivocó.
Thanks, Paul. Great to see the collaboration with your son. I was wondering...where does one get access to those schematics and diagrams you were using?

Base circuit trigger signals can range from 4v to 12v and every car is different. Most COP coils today are using a 4-5v base circuit trigger signal
@@ScannerDanner then there would be a base limiting resistor if there is a 5 volt trigger the voltage has to go land somewhere the base to emitter is .7 volts when it's forward bias
@@ScannerDanner love your video we just did about the transmission shortened solenoid great stuff
@@ScannerDanner my point is I'm sure there are five volt triggers just like digital pulses but you still have to draw the resistor in series with the base
You have been always a great Teacher mr. Danner
you're the best you've seen your way of explaining is very professional
Paul should have an emergency tool kit and get 2 relay testers. One for the garage and the other for road tests. Have a Actron CP9690 code tester to check codes and road tests. Also fuel pressure tester and timing light.
Master Tech from El Paso TX right here... wow... seriously wow... been with you since a long time scanner danner keep it up
Great video scanner danner love your teaching has given me confidence to test my vehicles
Your information is golden. Thank you for this video. I'm looking to swap out the TBI with a carburetor. ❤❤❤ 2000 Celica GT.
Stay with fuel injection!
But thank you, appreciate your comment
Watched right to the end. Great video.
Thanks for talking too much Paul! I've been doing this since the late 80's and never had this kind of detailed explanation of this system. A better understanding of how it works will make for a more confident diagnosis.
Thanks Jeff! Really appreciate your comment in light of the one I just pinned here.
I deleted that pinned comment. I should never have gotten involved. That was getting ugly fast and I meant the guy no harm. I actually feel bad now.
But thank you for your comment. It really means a lot.
Your welcome Paul. What you're doing is very helpful to a lot of people. Some may disagree but a whole lot more of us are very appreciative of what you do.
ScannerDanner! Dang, I always miss out!! I shoulda stayed around longer!!
Finally got some time to watch. Nice explanation Paul for anyone learning to understand how Toyota ignition systems work. On to part 2, when I get some time. ;-) Take care
Seems like you have alot of chapters, cool for me! I'm going to watch all your videos dude.
Do you have a video for my 2005 PT Cruiser, none turbo , manual. Only have 4 plug in harness. A/c.. it just will not pass smog! They keep telling me to do the drive cycle and did and done numerous times...can you help me out.???
Your methods and detailed explanations make it easy to understand as I follow your video. subscribed
Paul,great video man! 👍 Thanks for taking the time and explaining everything in detail,it’s very much appreciated! I bet Paul knew what’s wrong with this car on experience alone,the minute he realized he had no spark!
actually, that moment was when I saw the tach bounce and smelled fuel :-)
Hey man thanks for the video. 1st time watcher and immediate fan. I have a similar model celica that has started having intermittent problems, so at least now I know some more steps I can take when it stops again! I will watch some more of your videos in preparation but I enjoyed learning from the explanations so I think you have a new fan and maybe subscriber! Cheers from down under!
Heck yeah thats awesome! Thank you!
Yeah man that was sweet! I'm re-looming a car we're putting into amateur rally, the schematic was exactly what I was after :)
My igniter on my truck had a rusted out ground that was keeping it from firing.Notice you covered very little about ground on igniter.
From memory, we had an input problem, which would have been why I never needed to focus on the igniter ground
Man you give me golden information im very thankful
Hi Paul . it is very nice job , but I would like to discuss two points .....1/ the main purpose of IGF is giving feedback to ECM as confirmation that SPARK is already generated .... that means this signal is tied with Secondary NOT primary coil . so, I think that this diagram has something missed and I think that power feeding at time 27:20 is tied with IGF to give feedback signal to ECM that there are other voltage fluctuations on the feed line left after IGT ..... I meant there are two current flows in this line one when IGT and current flow in primary and the second current flow would be before secondary side as I mentioned on 27:20 . I hope if you could make another video as experiment 2nd point is if this secondary coil shorted , the system would completely shifted to Fail- Safe mode or what you call Lamb mode and shut off injectors completely ....... you know in some time .. if there is No Injection Pulse ... you have to look after IGF signal maybe there is shorted in the end , it is very nice video , thank you
Thanks for the great info. Master Danner.... Very intuitive... I'll be on the lookout for more vital videos... Thanks and God Bless....
Very nice class for your son and for us. Thanks!
Thanks Paul Danner great video thanks for your time and your time and for shearing your knowledge and experience thank you
To me - I always start with visual inspections- so I would have definitely checked the cap and rotor 👍👍✌️✌️✌️
Wheres the part 2 to show what condition the cap and rotor were in? Love the content btw!!!
Cliffhanger!! Well done, Mr. Danner.
one is a pellet gun its a powerline 822 (they had 177 version also), I still have mine from the 1970's
The NE signal indicates crankshaft position and engine RPM. The G signal (also called VVT signal) provides cylinder identification. By comparing the G signal to the NE signal, the ECM is able to identify the cylinder on compression.14/09/2022
NE Signal and G Signal - Toyota Engine Control Systems
Toyota Distributor and DLI Ignition Systems - explanation and guide
Toyota Single Coil and Distributor Ignition Systems, with computer controlled advance and 5-pin ignition systems
So here is a quick little explanation of Toyota ignition system
Ignition System Overview
This is basically the breakdown of the most common of toyota's ignition systems, where ignition timing is controlled by the ECU and the ignition system comprises of a single coil and distributor.
In short, what happens is the dissy is obviously spinning with engine RPM, and generating the variable reluctance (VR) signals "G1" and "Ne". Ne is the cam position signal from the multi-tooth wheel, giving the ECU the exact rotational position of the engine within it's cycle. G1 is a reference signal that the ECU can use to determine what cylinder the engine is up to.
The ECU reads these signals, then applies it's ignition advance according to its programmed ignition map, and sends the IGt signal out to the Ignitor.
The ignitor fires the ignition coil according to the IGt signal.
The ignitor also generates a return signal to the ECU - IGf - to let the ECU know that the ignition event was sucessful.
Pretty simple really.
Toyota Distributor and DLI Ignition Systems - explanation and guide
Toyota Single Coil and Distributor Ignition Systems, with computer controlled advance and 5-pin ignitor
The most common stumbling block people come across with wiring up an engine conversion is the ignition system. Often a second hand loom is used or you are making a loom from scratch, and when you get to the ignition system - you can't for the life of you match up what the fudge is what!
So here is a quick little explanation of Toyota ignition system and 5-Pin ignitors that should answer most questions about them.

The ignitor also generates a return signal to the ECU - IGf - to let the ECU know that the ignition event was sucessful.
Pretty simple really.
So how does one wire up the 5 pin ignitor?
The really annoying part about wiring up a conversion, is a majority of Toyota 5 pin ignitors after 1989 have the plug as part of the housing - meaning there are no wire colours to go by. This is quite the PAIN.
So here are the pinouts, and most comon wiring colours.
Note that the metal case is the earth for the ignitor, so make sure it is bolted to metal (the stock brackets usually provide this earth)
1/ B-R: Coil Negative (output)
2/ B: Tacho signal (output)
3/ B-O: Ignition power (12V+)
4/ W: IGt (input)
5/ W-R: IGf (output)
How does one wire this all up with an aftermarket ECU?
Well - this is easy! Most of you would be using a Microtech/EMS/etc etc which are all quite capable of using the stock signals and ignition system. Here is the way most of these will hook up to this type of Toyota ignition system.....
Most aftermarket ECUs want both a "cam position trigger" and a "reference trigger". The Toyota dissy in this system provides these triggers with a VR (variable reluctance) signal with a falling edge trigger. This "falling edge" part is important, because the ECU needs to have the signal go a particular way for the internal circuitry to detect the very low AC voltage from the VR signal and interpret that as a trigger event.
Some aftermarket ECUs allow you to select a falling edge or rising edge trigger through it's programming software, but some want the signal to be one or the other without the option of change.
Excellent teacher, very excellent class, very grateful. I have a problem in a 2006 nissan sentra the car is burning the ignition coils every month.
Thank you
COP system right?
ScannerDanner yes. Thank you
These Nissan COP coils have their own built in transistor. Most likely you a getting cheap coils and need to buy factory ones.
ScannerDanner thank you
The same has burned the factory coils friend. I have reviewed the condeser that brings and is bad. I'll try changing it. Thanks for answering and you help.
As always learned something I didnt know. Gotta say its why I've been watching for so many years. Thanks Danner!
Very detailed, way down in the engineering of the ignition system good job 👍
Paul, top drawer video, excellent explanation of circuit design !!!!!!!!!
wow....!! this is greats it can help me to run the ford lynx.... nice video good job sir......!!!
Well done m8, very informative. I started at vid 2, but awsome teaching points
thank you very much mr danner please a video how we can check synchroniation between cameshaft and cranckshaft sensors (signals and connections) thanks again .
Thanks alot for been the best teacher i have
You are very welcome, thank you!
@@ScannerDanneryesterday i was working on 4E engine with but i managed to watch your video n i sorted the problem
^With no firing from the distributor
^With no firing from the distributor
This video is freaking amazing! It was the final puzzle piece for me to fully understand how the ignition works for my Toyota Corolla :) The distributor is basically the same, but lacks the sensor for the 1 x 360 pulse. But it doesn't need the sensor, because the injectors all fire at the same time. Thank you so much, this helped a lot in my journey to replace the stock ECU :)
Nice! Great insight you have too on group fired injection systems. I'm impressed
WHAT.?? All this time I thought your first name was SCANNER.. Lol
Great, Now we're all messed up. Thanks Dan...ner Paul.
Oh ya.. Section 18 for the group fire.. Another great video Paul. Thank You
Cheers
I always tell guys I'm teaching that IGF stands for (I Got Fire). I actually like to scope the IGF when I have intermittent misfires on coil on plug Toyota's and you can actually see in the pattern what coil is fail/starting to fail.
That was just BRILLANT Scanner The Man Danner, Just tell your boy you'll give him a discount for cash, or can he afford you??
Lol, he can't afford me
Hey, great video, so detail and easy to fix as you explain. Thanks.
I have a 2001 Mazda Miata with a 1.8 VVT Engine that cranks but has no spark, also it is missing the fuel injectors. I bought the car like that. the fuel pump works but no spark from either coils.
Yessir Safety first!
Well sir you are awesome and just earned a new subscriber.
Awesome, thank you!
@@ScannerDanner I just refereed to this in my latest vid, you might get like 1 or 2 more views lol.
My old 1992 Civic died on me and did all this test and everything checked good. Had fuel, ignition and spark. Compression sounded good. Turned out distributor shaft bearing was going out and melted the rotor and it hit the cap turning it 90 degrees off. Spark was not firing at the right cylinder.
Thanks Paul. You greatly improved my diagnostic times. Priceless as a flat rate tech.
So cool so interesting, Paired fuel injection if some old Toyota cars had it what about the older trucks like the 22R or RE.
Thank you very much,clear explain ❤❤❤
what a good video master a question that range should have the clamp amperimetrica to be able to make all the measurements in the components of the car I am buying one but I do not know if with a 60 A is enough to make the measurements
francisco badillo thank you so much danner and you are good teacher abouttech
I really need one of those. My Corolla has a Celica motor also a 5 speed but I don't have any body to help.
To Mr Scanner Danner - Have you ever checked coils with a Hi-Pot test?
I don't know what that is 🤔
Good video, thanks, im dealing with same now, difficult to belive from a toyota even with more tham 25 yold
Great information good job I love your comments on comments and your experience does dictate your next move
Can't believe you remembered my joke lol. Waiting on your book in the mail :)
was that you? haha "take a drink"
Check for oil in the distributor cap. This was pretty common. If it's wet in there, you'll be replacing the distributor. Oil would come in through the shaft, and cause this if it went unnoticed for a while.
JES2381 How does oil cause a problem? What if the oil doesn't reach the distributor cap, but just gets the bottom of the ignition coil wet?
On this distributor design, the oil would need to be severe to cause an issue. On optical pick-ups used in Nissan and some GM distributors, the oil would interupt the signals.
The real issue with oil, is it shows there is wear in the distributor bushing and this can eventually cause the shaft to wobble and that itself can mess up the input signals.
ScannerDanner Thanks, Paul. I have a 1996 Toyota Corolla with stalling after running smooth for long time. In fact, it won't stall now after an hour. When I change the distributor seal, I'll see how much the distributor shaft wobbles. However, distributor air gap is 0.010 inch, in spec, so it seems distributor bushings not worn. Resistance of cam sensor and crank sensor (cold and hot) at ecm in spec. Resistance of ignition coil primary and secondary (cold and hot) in spec. I can't afford amp probe and scope...
Does it immediately restart after stalling or does it have to sit?
ScannerDanner I can restart immediately. Idles smooth for a few seconds before stalling again. I can tap gas pedal as it stalls to revive engine for another few seconds until it tries to stall again. If engine cools, say 15 minutes, it will idle longer, maybe 10 seconds, before needing to tap gas. However, can't seem to duplicate problem last few months. Ran an hour with no problems recently. Code never thrown.
Why did you choose uActivate over a remote starter? uActivate is on my wish list for this year.
I couldn't get to the starter S post from the top :-)
Great question! Just make sure you use my link when you buy it. You'll pay the same amount either way. I just get a little love from AES when you use my link. Thanks!
The sound of the engine can be to much raw fuel cleaning the piston rings and that's is normal after so many cranking without burning that mix. Good video
very good video I appreciate it very much greetings from Tijuana Mexico.
Paul have viewed plenty of you videos, find them very interesting and would like to thank you for taking he time to do this as they can be very helpful. In both diagnosing and repairing your own vehicle one question I have is what setting are a good starting point when using an oscilloscope as you may guess I am new to oscilloscopes to test automotive circuits?
Thank you! Scope setting vary greatly with what you are measuring. The best thing for you to do is to keep watching my videos and also my Picoscope basics part 1 and 2. You do not need a picoscope to learn from these.

Hi Paul
Thanks for the link videos were very interesting and informative, what is your opinion of the uscope as a first scope, for repairing my own car, any chance you could do some more examples of its capability.
Your son is a lucky kid gets to learn from someone that's great at there craft I would love to take your class unfortunately I don't live close enough
Fortunately I've created ScannerDanner Premium just for guys like you. And my son for that matter. He's starting to watch my classroom lectures now too as a junior in high school. He will be a beast if he keeps this up :-)
ScannerDanner what does it cost and I’m also interested in getting your book as well
Just $11 a month, Jay - no better bang for your buck in the automotive world. www.scannerdanner.com
Thank you Jay! You will not be disappointed. Foundational stuff is what I focus on.
Great video man
A start in gear would make great video.
So if you had a bad ignition control module on an obd2 system, would it always throw a code?
very nice tutorial
Good job
Yes he does it in laymens friendly terms. Mr danner your draggin it out. Less yappin sorry. This was 30min video you know that. Last 15 min is the gold too.
A lot of guys looking to learn need someone like Mr danner. Oh shit, I'm listening and you just said, "some of you are goin to say i talk to much. Most of you, will say yeah man sweet:)
There you go laymen terms, able to please most of the people most of the time, and some of us just have to live with it. Keep up the good work .
Those with my thinking have to understand. Mr danner has an agenda as well. If he could speak less he would , if the audience was a different one, Right? Aloha~
Hola.Disculpé mi ignorancia. Mi pregunta es: ? Porque la luz de prueba enciende en ambas terminales del inyector de combustible, una terminal es el positivo y la otra es negativo o el control si no me equivocó.
I got a request. Do a video on a Chevy HEI module and coil conversion on a 22RE... Its been done on 22Rs but not 22RE.. thanks
Thank you Paul . When the part 2 is coming?
I was going to include it in this one but it is another 25 minutes or so. I'll have it up soon.
Thanks Pauly !!!!
grasias por esos buenas clases
Don't forget to change the oil brother.😄😄😄😄😄😄😄😄😄GOD bless u.
Thanks, Paul. Great to see the collaboration with your son. I was wondering...where does one get access to those schematics and diagrams you were using?
I enjoyed this ! Whats the name of the starter relay you plugged up to remotely turn engine over ! Very nice tool there !
It is called a uActivate and only my friends at AESwave carry it. You can find it here www.aeswave.com/scannerdanner-c512/
