Hey Rich, thanks for the info but can you tell us how we can checkt if the data transfer works? I have a predator and on day to another i cant connect to the pcm

@villedamx Yes your jeep has a obd II connector it is located at the rear of lower left edge of dash.If you were sitting in the drivers seat it would be in front of your left knee.
Well I did not get it do you mean if the wires in different places that's means obd will never work?? Well its light up but never connect with my iPhone 4??
My light came on saying my psi is not showing how much air is in my tires. Now later on this evening my obi 11 light is on. Is there a way to fix this without putting my car in the shop.
I have a 95 dodge stratus es I have power on#16 pin & continuity on#4 & 5 pins but my scanner does not communicate with my computer,what could be wrong?
Ok, so I got 12V on 16, but I got 0.5V on 4. What does that mean? (In the car I’m testing, I’m suspecting either a problem in either the ECU or immobilizer.)
Ok I checked pin 4 and it reads 0.40 and pin 16 reads 11.77, I also checked back of the connector and looks fine, I checked all fuses and they are good , battery is good as well. Any advices Rich ?
@overshooter12 Specificaly. Measure the no 4 pin with the dvom meter negative connected to battery ground, Measure the no 5 pin against the same battery ground. Pin 7 if active should read 3 to 4 volts measured against [batt grnd] on this line [pin 7]you don't only want connectivity but also a active +3v. If you get zero volts on pin seven disconnect the battery and measure resistance between pin 7 and a good chassis ground. should be 300 - 600 milli ohms resistance.

Pin 16 should be over 12 volts,how many volts does your battery have.With your multimeter on the highest ohm setting pin 4 should read 0.How do the pins and wires on the back of the connector look.
Hi Hector,you battery is probably flat. a 12V battery(nominal voltage),must have a bit more than 12V.About the pin 4,it is shorted some where as the resistance is more than 0.25.follow you wiring from OBD2 plug to your ECU(electronic control Unit or the famous computer) and check all the fuses and everthing is okay,you may need to review all possible modifications done on your car or even contact an Auto electrician.
Rich, when you put the positive lead to the 4th pin top row from the left, did it NOT show continuity (no continuity) or am I just reading that wrong (not an expert with volt meters).
@richpin06a Thnks for the tip, but after looking all arround under the dashboard and after an intensive research on the internet, my car doesn't have a OBDII plug, it seems that my 96 jeep is an early 96 model (same 95 but with some patches) only the late 96 model has OBDII port available... anyway, thanks bro.
my jetta shows on pin 16 below 12 volts like 11. something volts , is that why I am not getting any codes from my car ? the scanner says no connection with computers car , also I checked ground and it showed me some numbers , should I get none ? if you can give an opinion would be helpful ,I just don't want to take it to the shop, they might say it was just a short and pay 400 dls
@overshooter12 Part 2. If pin seven has HIGH resistance the K line or diagnostic line is shorted to ground you need to trace the k line from the OBD 2 connector to the Power Control Module looking for a short to ground. consider if you did any work, or made any connections behind the dash recently or added any electrical components to your electrical system. try disconnecting things and check the resistance after each step. when the resistance returns to normal [300 ma] you found your short.
@@LuisMartinez-fr9gq Resistance measuring normally done between terminal six and fourteen normal resistance is around 60 ohms. Zero ohms [ no resistence ] normally indicate a short in the system. 120 ohms indicate one of the tremnating resistors are not connected. Sorry about the error but every time i do these test i have to review the procedure.
I have a 2001 Hyundai Santa Fe GL 2.4 liter, OBD II, i have pins 4, 5, 7, 8 on the top. On the bottom i have 12, 14, and 16, i just do not know what pins to touch to do this test since I do not have the ones he show on the video.
My OBD2 connector has power but it does not communicate with my scan tool. I am getting 12+volts to pin 16 but i am getting 1.1ohms at pin 4. I assume i have a bad ground then. Am i correct? Any ideas? Thank you.
R F and if you got no power at pin 1 check your fuses .look for tarnished fuses they go like a browny dingy colour. If you see this either replace or clean them
The data pins are not diagnosable by measuring voltage. It are digital connections. You would need an osciloscope to see whats happening on those connections, and then understand what is actually being send which is not easy (or could call it even complicated, a bit of a study)
Una pregunta amigo, alguna vez as trabajado en 2001 Hyundai Santa Fe GL 2.4 motor, quiero saber cómo testear los CAN BUS, pero mi connector no viene con el pin no.6.
For the test of pin 4 he had the multimeter set to Ohms (200K). Then when he was checking Pin 16 (the power pin) for volts he changed the multimeter to (V DC) volts (20).
@@eyesalooking Informative 1-test the red wire to pin-16 and the black wire to ground, and the multimeter on 20 volt There can you read the battery=12,22 volt You can test the pin=4 and pin-5 with the multimeter, the red wire to pin-16 and the black wire to pin-4 or pin-5 , and the multimeter on 20 volt There can you read the battery=12,22 volt, the same as the second test=1:50

Hello do you know what wire is in the pin 13 on Toyota Corolla..
It did show continuity so the ground was good at that pin.
Ok I have those readings too,so what's next? Y doesn't my scan tool connects with my computer? Thank you.
Hi I have a Volvo s80 2000 is not starting but the starter is working and the engine lift is off what might be a problem?

If it is continuity it will show 0, how it was in the film.

R F pin 1 needs to be displaying around same voltage as pin 16 .pin 4 is your ground and pin 5 is your signal ground.

The data pins are not diagnosable by measuring voltage. It are digital connections. You would need an osciloscope to see whats happening on those connections, and then understand what is actually being send which is not easy (or could call it even complicated, a bit of a study)

@villedamx very strange that is a oddball
zafira vauxhall mk 1 is it same pins
Looks like your battery is on the way out. Should be around 12.6 or higher depending on how long ago it was driven.
Excelent video.
Thank you.
You don't need to move slowly to stretch the video. You can sing a song. It gets less boring.
Very good for me thank you
Pin 4 is SIGNAL Ground and isnt Pin 5 Signal Power?? could have sworn thats what I read in my book and will get back to this thread at a later date.
Those look like data pins.
What is the multimeter set too?
For the test of pin 4 he had the multimeter set to Ohms (200K). Then when he was checking Pin 16 (the power pin) for volts he changed the multimeter to (V DC) volts (20).

1-test the red wire to pin-16 and the black wire to ground, and the multimeter on 20 volt
There can you read the battery=12,22 volt
You can test the pin=4 and pin-5 with the multimeter, the red wire to pin-16 and the black wire to pin-4 or pin-5 , and the multimeter on 20 volt
There can you read the battery=12,22 volt, the same as the second test=1:50
I just wonder if it's normal the volts, 11.77 and the ground 0.40 ,,,,,,,,my cherokee reads over 12 volts
When you say "it should show some continuity" at the 4th pin, is 0.00 showing continuity?
Yes.
What to do next if no power to pin 16?
check your fuses particularly aux and cig lighter they usually connected
thank you Richpin06
OK, So now what?! what is the cause of the pin 4 problem?
Bernie Denis ,the cable connected to pin 4 can be shorted some where,it is necessary to follow the wiring until you find where is the problem.
Thank you sir 🙂
Most welcome
you didn't checked the link...just the power... :(
Yes that is right. rich
The real problem is that manufactures put the data pins in all different locations in the obd connection 🤦
So much for ISO 🤬
