Chassis Control Module

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2016 GMC Sierra 3500 HD, 2016 GMC Sierra 2500 HD, 2016 GMC Sierra 1500, 2016 Chevrolet Silverado 3500 HD, and 2016 Chevrolet Silverado 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

The K38 Chassis Control Module (CCM) is a serviceable GMLAN module. The chassis control module sends the low power commanded duty cycle signal to the trailer brake power control module. The trailer brake power control module amplifies the signal and provides an output that is required to drive the trailer brakes.
