Normal Operation

The Restraints Control Module (RCM) measures vehicle yaw rate, roll rate, lateral acceleration and longitudinal acceleration and sends the information to the ABS module along dedicated Controller Area Network (CAN) circuits. This dedicated CAN is used only for communication between the RCM and the ABS module. The yaw rate sensor, roll rate sensor, lateral and longitudinal accelerometers are contained in the RCM.

DTC Description	Fault Trigger Conditions
U0151: 88 - Lost Communication With Restraints Control Module: Bus Off	This DTC sets when there are expected messages such as yaw rate sensor, lateral and longitudinal accelerometers missing from the RCM for more than 5 seconds.
C0061: 28 - Lateral Acceleration Sensor: Signal Bias Level Out of Range/Zero Adjustment Failure	This DTC sets if the lateral acceleration sensor signal is greater than 7.0 m/s² . Also, if the absolute value of the calculated lateral acceleration signal offset is greater than 1.7 m/s² .
C0061: 64 - Lateral Acceleration Sensor: Signal Plausibility Failure	This DTC sets if the lateral acceleration sensor signal does not match the other stability sensor signals (steering angle, yaw rate, longitudinal acceleration, etc.).
C0062: 28 - Longitudinal Acceleration Sensor: Signal Bias Level Out of Range/Zero Adjustment Failure	This DTC sets if the absolute value of the calculated longitudinal acceleration signal offset exceeds the tolerated threshold of 0.19 G.
C0062: 64 - Longitudinal Acceleration Sensor: Signal Plausibility Failure	This DTC sets if the longitudinal acceleration sensor signal does not match the other stability sensor signals (steering angle, yaw rate, longitudinal acceleration, etc.).
C0062: 76 - Longitudinal Acceleration Sensor: Wrong Mounting Position	This DTC sets if the longitudinal acceleration sensor signal does not show acceleration or deceleration respective to the direction the vehicle is moving, based on other sensor inputs.
C0063: 28 - Yaw Rate Sensor: Signal Bias Level Out of Range/Zero Adjustment Failure	This DTC sets if the yaw rate sensor indicates movement when the vehicle is standing still or if the absolute value of the calculated yaw rate sensor offset is greater than 6.0 m/s2.
C0063: 64 - Yaw Rate Sensor: Signal Plausibility Failure	This DTC sets if the yaw rate sensor signal does not match the other stability sensor signals (steering angle, longitudinal acceleration, lateral acceleration, etc.).
C0064: 28 - Roll Rate Sensor: Signal Bias Level Out of Range/Zero Adjustment Failure	This DTC sets if absolute value of the calculated roll rate signal offset is greater than 7 degrees.
C0064: 64 - Roll Rate Sensor: Signal Plausibility Failure	This DTC sets if the roll rate sensor signal does not match the other stability sensor signals (wheel speed, steering angle, yaw rate, longitudinal acceleration, lateral acceleration, etc.).
