GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hello and welcome. My name is ***** ***** you for visiting the site, I will be happy to assist you today.
It would be hard to say for sure what the problem(s) are. However, the C0265 had a service bulletin for the EBCM ground, (G110). Which may also be what set the C0298, ( PCM has lost the ability to reduce engine torque.)
If you give me your email address, I can get the test instructions for both, including the bulletin, and put it in a PDF file, (it is rather large) and send it to your email address for as little as possible.
You will just have to accept the additional service offer and ENTER your email address in the “ENTER CONTACT INFO” section so that I can see it, Thanks
Do you still need any help with it?
I do apologize, although we are not allowed to discuss money with customers, please let us know if you need anything in the future. Best of luck with the dealership and thank you for using the site.
