Circuit/System Verification

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 GMC Yukon XL, 2012 GMC Yukon, 2012 Chevrolet Tahoe, 2012 Chevrolet Suburban, and 2012 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

If other DTCs are set, diagnose those DTCs first.

If no other DTCs are set, diagnosis is accomplished by testing for a condition on the CAN circuit. Refer to Scan Tool Does Not Communicate with High Speed GMLAN Device .
