Pinpoint Test G : Stability Control Sensor Signal Faults: Notes
Refer to Vehicle Dynamic Systems for schematic and connector information.
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. The yaw rate sensor, lateral accelerometer and longitudinal accelerometer are contained in the RCM. A failure of the HS-CAN2, an incorrectly installed RCM, an internal failure of the RCM or the internal sensors causes the ABS to set one or more Diagnostic Trouble Codes (DTCs).
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C0061:28, C0062:28, C0063:28, C0064:28 | Lateral Acceleration Sensor, Longitudinal Acceleration Sensor, Yaw Rate Sensor, Roll Rate Sensor: Signal Bias Level Out of Range / Zero Adjustment Failure | These Diagnostic Trouble Codes (DTCs) set in continuous memory and on-demand if the sensor signal is greater than the programmed maximum plausible sensor signal. |
| C0061:2F, C0063:2F | Lateral Acceleration Sensor, Yaw Rate Sensor: Signal Erratic | These Diagnostic Trouble Codes (DTCs) set in continuous memory and on-demand if the lateral acceleration sensor signal is out of range when the vehicle is standing still. |
| C0061:64, C0062:64, C0063:64, C0064:64 | Lateral Acceleration Sensor, Longitudinal Acceleration Sensor, Yaw Rate Sensor, Roll Rate Sensor: Signal Plausibility Failure | These Diagnostic Trouble Codes (DTCs) set in continuous memory and on-demand if the sensor signal does not match the other stability sensor signals. |
Possible Causes
- Underinflated tires
- Incorrect or mismatched tires
- Network communication concern
- Incorrect or incomplete ABS module IVD Initialization
- Incorrectly installed RCM
- RCM
