Per wikipedia...The BNC (Bayonet Neill-Concelman) connector is a miniature quick connect/disconnect radio frequency connector used for coaxial cable. It features two bayonet lugs on the female connector; mating is fully achieved with a quarter turn of the coupling nut. BNC connectors are used with miniature-to-subminiature coaxial cable in radio, television, and other radio-frequency electronic equipment, test instruments, and video signals. The BNC was commonly used for early computer networks, including ARCnet, the IBM PC Network, and the 10BASE2 variant of Ethernet. BNC connectors are made to match the characteristic impedance of cable at either 50 ohms or 75 ohms. They are usually applied for frequencies below 4 GHz[1] and voltages below 500 volts.[
Hey ScannerDanner! Just wanted to say thank you for this video. I have a 96 cherokee similar to the one in this video, but I just had the engine rebuilt and the whole 9, so she runs great. Even though I only work on cars as a hobby and work on computers for a living, I still watched the whole thing because I like how knowledgeable you are. Just got subscribed, and I plan on watching many more of your videos! - Jason
That large interactive screen as a training aid is wonderful. I sure appreciate the lesson Paul. I can't tell you I understand it all yet but I'll be back.
I hope to do so soon I really like automotive electronics and I have a workshop and vehicles under electronic problems and I do not lose any of your videos thank you very much friend
I have a Pico and I love my Pico and ScannerDanner videos. Might seem like overkill if you look at the price for a diy, but this is fun and I am driving high miles car and save money taking care of them my self. But this would not have been easy without ScannerDanner.
This is so damn good.. what a great case study and brain-storming session! As much as I dreaded going to class, I loved it once I got there.. this is certainly making me want to enroll at the local J.C. to brush-up on the skills again. I have my California enhanced area test/repair smog license. It was a daunting prospect in the beginning, but I quickly fell in love with the advanced level training. I subscribed and I'm also looking into your premium membership. Thanks for taking the time to do this!
The major clue here is the shift of timing over separate traces during the seminar, even though timing during each trace seemed to be consistent. Somehow the CMP sensor is able to rock back and forth, giving inconsistent time. I suppose that could happen electronically, too, but more likely it is mechanical.
The way I learned and remember a 4.0l jeep and many inline 6 cylinder engines firing order is easy to remember, it goes.......to date her is she TOO YOUNG, TOO OLD or JUST RIGHT. TOO YOUNG would be 15. TOO OLD would be 36. JUST RIGHT would be 24. And that is your firing order -->15.36.24
another good video dan,i have had problems stump me for days,but in the process i would learn a 1000 things that went to the next job,kids these days will turn the ticket over to someone else if it a quick buck,
Hi Paul something that might interest you, measuring very low current with an amps clamp, i saw a clip on it, if you rap the wire round the clamp several times, say 6 it will intensify the magnet field and you should get a reading, the answer you get has to be divided by the number of turns....from Fred in England.
Great case study. I use a Rigol DS1102E 100MHz Digital Oscilloscope and typically when my leads are too short I take a length of ethernet cable or speaker wire to extend the leads like a long jumper wire. I haven’t seen any signal degradation with this method. Thoughts?
Here I am 7 years later looking at this video and just for what it's worth I'm guesstimating at this point without doing further diagnosis that it did jump time maybe cruising along tagged the valve that's the way if we have the loss compression or maybe even tag more than one due to a sloppy chain I know it's a Jeep but 40 years ago I was told that on Chrysler that when you have a distributor go in there start to roll the engine over by hand to the distributor moves then start to roll backwards if you have more than 12° variance and the distributor starts to move time for a timing chain
Keep in mind, this engine has been cranking with fuel pump commanded on when engine sees crank signal. Oil needs to seal the rings on the cylinder wall. Fuel washes oil, if you know there is a lot of fuel in a an engine that has not run, do not automatically assume there is a mechanical problem causing low compression. A skipped timing chain can raise/lower compression however we would see more erratic patterns than just one cylinder. Fuel washout is going to affect the cylinder that is firing the latest or not at all
When cam and crank waveforms are not in sync the next thing I always do is check cam timing with a pressure transducer. If the cam timing shows good with the pressure transducer then I would be looking at the flywheel or distributor. If the pressure transducer shows a timing misalignment then I would be looking at the front of the motor for a timing chain/ belt issue.
My first thought? That is the cleanest engine bay I've seen in a long time! Seriously, what's up with that? Meticulous owner, or a secret diagnostic criteria? ;)
+Ozzstar no problem man. It is something I haven't done well with in the past. (the description section of my videos). I'm in the process of changing that on ALL of them!
On this model Jeep I have seen crank sensors installed wrong giving a low amplitude reading and causing a no start. Care must be taken to not remove the felt tip but let it lightly contact the flywheel and to use the semi circle mounting clip to fit the curve of the new sensor when tightening.
The 'guy' whose initials are BNC is called "British Naval Connector"! Glad your Varis leads were too short - it meant you had to use the Pico!!! Personally, I don't think you can beat Pico. I know you're a fan, too, but with so many features and such powerful software and so many possibilities in terms of functions and accessories, Pico makes everything so simple for every user; novice or expert.
Mr. Danner very good classes I would love to attend them but apart'm from mexico and I do not speak much English but I would like to study with you so congratulations follow
on the first test the firing event from the coil is lined up with the fourth pulse of the crank sensor but the plug wire pulse is lined up with the third pulse of the crank .why did that change
Nice video Dan, love my pico too, I see u got the new pico hardware box. I am still using my old one, still works grea. What version of software are u using?
My Hummer series with the bad valve seats would be a good one to watch. A scope and an in cylinder pressure transducer would be the tools you need. You may be able to catch it with an old school gauge and do a running compression test.
+salem ogla I do. Check out ScannerDanner Premium. There is a 14 day free trial. More than 270 videos and counting and a lot of them are this format. Oh, also, the rest of this Jeep series is on there too
yes you can and yes it is safe. You limitations are with the size of the wire (the jaws must close all the way) and then also, I believe 4v output is the max, so 400 amps (on a 10mv/a scale)
Good morning. in a twin-cylinder engine, looking at the CKP x primary/secondary of the coil, each cylinder shows a different timing value, each with a different tooth on the ignition pulses, for example: at idle, the ignition firing of cylinder 1 FRONT) appears on the 13th tooth (the TDC mark is on the eighth tooth of the rotor) and the ignition firing of cylinder 2 (REAR) appears on the eighth tooth (the TDC mark for cylinder 2 is on the second tooth of the rotor), with the ignition point of 5° (BTDC) in the workshop manual, what generates this difference in readings on the oscilloscope?
Another good video Paul.. Will the pico hook up to any laptop? It is thought provoking ,that you prefer the pico to the verus. The verus is a good tool but really expensive. Does the waveforms on the verus make you guess and scratch your head? I realize that these sound like stupid questions. out the door we are looking at 20+ grand just to stay up to speed on the vehicles coming into the shop. There's no way some of our employers are gonna she'll that much you. Mines fussing about a 300 dollar torch. Just trying to find a way around the cost so I'm not working for Snap-on or Asewave. How are some of you doing it?
+Michael Nicholson Yes it will and the software to run the pico is free. You do not need to spend the $10000 on a Verus. There are other paths you can take for sure. Don't get me wrong, I love my Verus too but when I need detail, I'm pulling out the pico
Like I said I'm just poking around I'm a little bored after 51 almost 52 years I called it quits use lab scopes for over the last 25 plus years before they were digital I like your presentation you letting everyone know you have to go in a little bit further to pin it down even though you spend a lot of time here
Hi Dan this is Marcelo from Argentina I really enjoy your virtual classroom guys! I would like to have the money and visa to go there "Rosdale"....Thanks Very Much for share your work with us!!
how does the ecm know where tdc on no1 is... the crank sensor doesnt seem to have an identifiying blip.. it might work out tdc by using cam and crank signals together... meaning if the dizzy is installed wrongly tdc could be way off..
Distributor engine right? It doesn't need to know where #1 is for spark as it is the same coil firing each time. So the cam is needed to ID# 1 cylinder for injection control
HI DANNER, I HAVE TWO MONTHS HAVING SUBSCRIBED TO YOUR CHANNEL. EISH, YOUR KNOWLEDGE AND VIDEOS ARE TOO ADVANCE FOR ME TO CAN FOLLOW ON YOU.

YOUR NEW SUBSCRIBER M.B.S MOSHITOA( S AFRICA)
ScannerDanner That's what I was thinking. It's a 96 4.0. I replaced the distributor after the old ones gears were eaten away. I got the new one close to being in time, but I still get all cylinders misfiring. I took it to a mechanic. All he did was cut the mount braket off of the distributor so it can be turned in place, and he set it correctly. But now I'm thinking the distributor turns itself out of time due to not having the bracket. Super dumb that he did that in my opinion. Probably need a new distributor now.
Tyler, you need to see the rest of this series. Open the description section and at least read what the fix was. I can get you set up for a free trial on my premium channel so you can see the rest. Just email me at support@scannerdanner and mention this exchange and I'll set you up.
Maybe it never got an oil and filter change in a long time and theres no oil pressure for the chain tensioner so the chain is loose leaving the timing out that bit :):)
its probably got the older batch fire fuel injection..... . but even modern engines can run with no cam sensor..... GM 3.1 for example but the injector timing will be off....hard starts, rough idle, reduced MPG

+carlos favela you speak it very well my friend. At least in print you do. I wish I spoke Spanish. I need to work on that
At what degrees in rotation does the injector fire the fuel into the cylinder
Typically during the exhaust stroke, way before the intake valve opens. Of course GDI systems have changed all of that
on the first test the firing event from the coil is lined up with the fourth pulse of the crank sensor but the plug wire pulse is lined up with the third pulse of the crank .why did that change
join you in person would be nice but I have a problem with distance... Denmark is a pretty long way to travel....

do you have a video on diagnosing weak valve springs, i know jeep and gm had problems because i have installed them for misfire codes

is it safe to measure the coil amp without using the amp clamp in series is it safe for a 10 Mohm scope
+stalker Linux lab scopes do not offer direct amperage measurments
Am I able to use a timing light to set my 4.0 timing?
What year is your jeep? On the model I am showing, no. Timing is not adjustable. It is based off the crank sensor triggered by the flywheel.
ScannerDanner That's what I was thinking. It's a 96 4.0. I replaced the distributor after the old ones gears were eaten away. I got the new one close to being in time, but I still get all cylinders misfiring. I took it to a mechanic.

Maybe it never got an oil and filter change in a long time and theres no oil pressure for the chain tensioner so the chain is loose leaving the timing out that bit :):)
fun stuff
cool.
Firing order is usually cast into intake, if not 15 is too young, 36 is too old, 24 is just right...
One cyl has low compression, another has very high compression. the rest appear about the same.
+gbowne1 Guess you did not watch the entire video and listen to the man explain why.

My 1990 jeep 4.0 starts and runs with the cam sensor unplugged.
