The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

 

Condition/Concern

Some customers with a 2.4L engine and RPO UW6 may complain that their subwoofer is inoperative. Equinox and Terrain models with a 4 cylinder engine are equipped with an Active Noise Cancellation (ANC) system – which works to reduce the amount of noticeable noise at certain vehicle speeds. The ANC system works with the vehicle’s audio system to create sound waves that cancel out torque converter clutch (TCC) noise.
