Conditions for Setting the DTC

WARNING: This page is about a different car, the 2014 GMC Yukon XL 1500, 2014 GMC Yukon, 2014 Chevrolet Tahoe, and 2014 Chevrolet Suburban 1500. 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.
