Pinpoint Test BH: Stability Control Sensor Signal Failure Faults
Normal Operation and Fault Conditions
The ABS module receives vehicle yaw rate, lateral acceleration, longitudinal acceleration and roll rate from RCM over the HS-CAN2, through the GWM. The yaw rate sensor, lateral accelerometer, longitudinal accelerometer and roll rate sensor are all contained in the RCM. A failure of the HS-CAN2, an internal failure of the RCM or the internal sensors causes the ABS module to set one or more Diagnostic Trouble Codes (DTCs).
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS C0061:28 | Lateral Acceleration Sensor: Signal Bias Level Out Of Range/Zero Adjustment Failure | Sets when the ABS module detects the sensor signal is greater than the programmed maximum plausible sensor signal. |
| ABS C0061:64 | Lateral Acceleration Sensor: Signal Plausibility Failure | Sets when the ABS module detects the sensor signal does not match the other stability sensor signals. |
| ABS C0062:28 | Longitudinal Acceleration Sensor: Signal Bias Level Out Of Range/Zero Adjustment Failure | Sets when the ABS module detects the sensor signal is greater than the programmed maximum plausible sensor signal. |
| ABS C0062:64 | Longitudinal Acceleration Sensor: Signal Plausibility Failure | Sets when the ABS module detects the sensor signal does not match the other stability sensor signals. |
| ABS C0063:28 | Yaw Rate Sensor: Signal Bias Level Out Of Range/Zero Adjustment Failure | Sets when the ABS module detects the sensor signal is greater than the programmed maximum plausible sensor signal. |
| ABS C0063:64 | Yaw Rate Sensor: Signal Plausibility Failure | Sets when the ABS module detects the sensor signal does not match the other stability sensor signals. |
| ABS C0064:28 | Roll Rate Sensor: Signal Bias Level Out Of Range/Zero Adjustment Failure | Sets when the ABS module detects the sensor signal is greater than the programmed maximum plausible sensor signal. |
| ABS C0064:64 | Roll Rate Sensor: Signal Plausibility Failure | Sets when the ABS module detects the sensor signal does not match the other stability sensor signals. |
| ABS U0151:00 | Lost Communication With Restraints Control Module: No Sub Type Information | This DTC sets when the ABS module does not receive any messages from the RCM within the allowed time. |
| ABS U0452:00 | Invalid Data Received From Restraints Control Module: No Sub Type Information | This DTC sets when the ABS module receives the following messages from the RCM with invalid data; RCM serial number, impact event status, lateral acceleration, longitudinal acceleration and sensor cluster state. |
| ABS U0452:86 | Invalid Data Received From Restraints Control Module: Signal Invalid | This DTC sets when the ABS module receives the yaw rate messages from the RCM, but the messages contain invalid data. |
