Description
The yaw rate sensor, lateral and longitudinal accelerometers are contained in the Restraints Control Module (RCM). The RCM measures vehicle yaw rate, roll rate, lateral and longitudinal acceleration and then sends the information to the Anti-Lock Brake System (ABS) Module along with a dedicated Controller Area Network (CAN). This dedicated CAN is used only for communication between the RCM and the ABS Module. The information sent to the ABS module is used to help determine if the AdvanceTrac® system needs to be activated. This Diagnostic Trouble Code (DTC) sets in continuous memory and on-demand when there is a communication issue between the ABS module and the RCM.
