Ok
Chevy Mechanic: J Hall, ASE Certified Technician replied 2 years ago

No TSB's on that code. I can give you the diagnostic procedures, but you will have to have an MDI and the GM software to run it, along with access to the GM database. Such is the nature of computer diagnosis today.

Also no recalls.

What does TSB and MDI stand for?
Chevy Mechanic: J Hall, ASE Certified Technician replied 2 years ago

Sorry about that. TSB is technical service bulletin. These are easy fixes for common problems that have been discovered by techs in the field. An MDI is a special scan tool used by GM techs since 2012. It is the only scanner that can be used on the 2015 and newer GM vehicles to properly diagnose certain trouble codes. The code you listed, P2645 is a GM specific code and the diagnostics are not readily available to the general public, unless you want to pay for them.

There is a fuse that protects that circuit. I will look it up and tell you where it is. If the fuse is blown, it may mean that circuit is shorted to ground somewhere.

Chevy Mechanic: J Hall, ASE Certified Technician replied 2 years ago

I am sending an overhead drawing of the fuse block that is under the hood in the engine compartment. I have circled fuse number 11 in red ink. Check that fuse to see if it is blown. If it is, put in a new one. If the new one blows out right away, then you have a short to ground on that circuit that will have to be diagnosed and repaired.

I don't want to mess with it because I don't know much about cars
Chevy Mechanic: J Hall, ASE Certified Technician replied 2 years ago

For this problem, it would probably be best if you took the car to the dealer. An independent shop might be able to repair it, but the dealer techs have more special tools (like the MDI), knowledge and training on these vehicles than anyone else. I wish you well on this repair. Thank you for using JustAnswer.
