Bought a 2013 Sierra hybrid, looking for schematics, Diagrams, and a good maintenance manual. Any suggestions on where to look?

 

easiest is a monthly subscription to all data. I'm not sure where you'd find or if they every printed a gm shop manual for hybrid specifically.

gm didn't really support these very well for their dealer techs even when new.

 

I will look in my Google Drive
and post a link to manuals I know I have.

 

Any help is appreciated thank you

 

Went ahead and got an account with all data. The problem with it is it doesn’t start, has a service hybrid system and a p1682 code, and p0ab9, p0bbb (hybrid battery is dead). I did replace the battery in the engine bay which was also dead the new battery was fully charged before installing it. Everything else seems to run when you have the key in auxiliary position no complains for the truck except service hybrid, and the abs light is on. I would guarantee it has been jumpstarted the wrong way, but I can’t prove that (bought it for pennies at an auction as a fixer upper).

 

Also I have a few diag/code readers my best one is an autel 808 pro

 

you'll probably want a good scanner, if you don't already have one. pick up cheap China tech 2. they are kinda a must have for these.

you can search for jump assist and hopefully it can bring the battery up enough to crank it. without the hybrid battery they basically do nothing. if you plan to keep it, you'll probably need to replace or rebuild that.

you can look at the snap shot data from each code, see what was going on when it set the code but mostly just get the hybrid charged up.

 

I am not able to find the "reverse charging" procedure for you.

I've forgotten the proper terms GM uses.

 

Jump assist mode?

Any suggestions on charging or tips or watch out for. I have the battery open and there are cells that read zero and also more all the way up to 7v. I’m considering charging them Individually or in two then balancing them all.
