Normal Operation and Fault Conditions

The RCM supplies the stability/traction control system with the yaw rate, roll rate, lateral and longitudinal accelerometer over a dedicated HS-CAN bus. If the RCM detects a fault with communications with the ABS module or dedicated CAN bus circuits, it sets DTC U0028:08 or U0028:88. 

The RCM does not request the IPC to illuminate the airbag warning indicator if either DTC U0028:08 or U0028:88 is set.
