Conditions for Setting the DTC

WARNING: This page is about a different car, 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 TCCM monitors the front axle switch signal circuit and the front axle actuator control circuit for unexpected voltages. The DTC sets if the TCCM detects a high voltage when a low voltage is expected or a low voltage when a high voltage is expected.
