GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hi there, I am Cam. Did you happen to boost the vehicle or put a charger on it recently? Do you have the Vin handy?
OK, taking a small wire from those pins on that module and grounding that out.
Ignition switches are common, tell me this, is the check engine light on when you turn the key on?
ITs less about what code, but that its on and it indicates the ECM is alive. Does it show the gear then?
Is the IGN 0 fuse getting power with the key on? This is in the left dash fuse block.
Ok, Then we need to see if we can see any transmission codes with the scanner.
OK, that makes it difficult. I am thinking transmission module is faulty but I am not willing to advise you to replace it until we have any more codes.
OK, let me know what codes it sets.
Indeed it is. Is there more I can get you tonight?
