Hello, my name is***** engine do you have? Thanks.
I am fine doing this over chat which will be cheaper for you too.
This code sets when the PCM determined that it did not receive any Transmission bus messages over the Data Bus line for 20 seconds. When it sets it usually means the transmission control module has failed. During problem Check for power to the TCM on pins 11 and 56. Check for good ground on pins 37, 39, 53, and 57. Verify no voltage (less than 100 mV) on pin 8. If all OK, replace the TCM. Here is a picture to help locate, let me know if you have more questions. Thanks.
Yes because the transmission range switch which tells vehicle you are in park/neutral goes through transmission control module. Let me know if you have more questions, thanks.
I'm happy to help, let me know how it turns out or if you run into more questions. You can reply to this answer at any time without additional fees. Thanks!
No problem, make sure to keep me updated. Have a good evening!
Correct, then just reply like you are now.
Thanks, I'll talk to you later.
Best way to figure it out is look at pin numbers/colors on diagram and see what connector matches. Pin 1 is light green/black and pin 2 is tan black, pin 3 is violet, and pin 4 is empty.
Key should be in on position.
Also verify no voltage on pin 8, if all are good then I agree TCM needs to be replaced. Let me know how it goes, thanks.
I meant to say it should have voltage, so it looks like everything is testing out OK leaving TCM as cause. Let me know how it goes, thanks.
Let me know how things go when you get a chance to replace. There is still a possibility the problem is PCM but unlikely and there is no way check more then we have. This code is usually caused by TCM though. Keep me updated. Thanks.
I think it will, I'll talk to you later. Thanks.
