Location of the Brake Electronic Control Module (ECM)
The Brake Electronic Control Module (Brake ECM) is the main component in the brake electrical system. The Brake ECM is located in the compartment at the rear of the cab. The Brake ECM has several input signals and output signals. Refer to Illustration 1 for the input signals and the output signals.The Brake ECM controls the Automatic Retarder Control (ARC) and the Traction Control System (TCS) functions. The Brake ECM receives information from various input components that are listed in Illustration 1. The Brake ECM uses this information to determine if the service and retarder brakes should engage for the ARC. The Brake ECM also determines the engagement of the parking and secondary brakes for the TCS. The output components are then activated to apply the ARC or the TCS.For additional information, see the Service Manual, "Automatic Retarder Control (ARC) System" and the Service Manual, "Automatic Electronic Traction Aid (AETA) (Traction Control System)".The Brake ECM also monitors input signals from the rear axle system.The Cat Data Link is used to share information with the Power Train Electronic Control Module, Engine Electronic Control Module, and the Vital Information Management System.
