Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I am Mike, welcome. I'm reviewing your question.
I don't have a repair manual for the 2016 model yet, but the 2015 manual says "
If DTC C056D is set
Check power and ground on the engine wiring harness for faulty
connections or corrosion before replacing the K43 Power Steering
That would be the "a/c cmprsr mdl/batt rvc" fuse in the underhood fuse block, left side of engine compartment.
The ground is G121 at the under the vehicle at driver door on body mount frame post.
