WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The output command is turned off while the malfunction is present.
The modules use a default value for the missing parameters.
The module(s) is never signaled, therefore the specific subsystem(s) will not function.
The vehicle will not start while the circuit is shorted to ground.
