Usually when this happens it is due to an aftermarket programmer inside the PCM.
so what are options.. i need to scan it again because im gettling a glitch in the tranny all of a sudden it doesnt wanna shift out of second
When it won't shift out of second does the overdrive light flash?
So it is detecting a transmission fault. If you plug the scan tool into the vehicle and then start it will it continue to run?
if i plug the scan tool in it will not start and if i start it first and then plug the scanner in it dies. and it wont read with the engine off key on. it just says it cannot communicate with the vehicle
If you go into the back of the PCM is there a chip installed?
Do you have a backup scan tool to see if the same issue occurs?
i will have in the morning. i'll let ya know what happens
just close this thread. i couldnt wait anymore. took it to a dealer
Do you have a wire diagram by chance to pin out the data link connector in case there is a short.
I'm aware of that but I have a full time job as well. I am unable to be on here all of the time.
i understand completely. i wasnt blaming you. i just wanted you to know
I understand. If I can help with anything else please just let me know.
