I have a code that is being thrower twice in a row P0C00 drive motor “b” high current what the hell is this

 

First off congratulations on having one still operating! The companies who made parts for GM on those stopped long ago.

Since it's not a 2-mode I'm not sure of that cause. There is no Drive Motor "B" in that vehicle.

Can't find the code in service manual

 

a short somewhere your leaking current
or your controller is broke try resetting see what happens
