Pinpoint Test G : Stability Control Sensor Signal Failure Faults: Notes
WARNING: This page is about a different variant/trim than selected.
Refer to Vehicle Dynamic Systems for schematic and connector information.
Normal Operation and Fault Conditions
The RCM measures vehicle yaw rate, lateral acceleration and longitudinal acceleration and sends the information to the ABS module over a private HS-CAN. This private HS-CAN is used only for communication between the RCM and the ABS module. The yaw rate sensor, lateral and longitudinal accelerometers are contained in the RCM. A failure of the private HS-CAN, RCM or the internal sensors will cause 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 | Lateral Acceleration, Longitudinal Acceleration, Yaw 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 sensor maximum plausible signal. |
| C0061:2F, C0063:2F | Lateral Acceleration, Yaw Rate Sensor: Signal Erratic | These Diagnostic Trouble Codes (DTCs) set in continuous memory and on-demand if the sensor signal is out of range when the vehicle is standing still. |
| C0061:64, C0062:64, C0063:64 | Lateral Acceleration, Longitudinal Acceleration, Yaw Rate Sensor: Signal Plausibility Failure | These Diagnostic Trouble Codes (DTCs) set in continuous memory and on-demand if the lateral acceleration sensor signal does not match the other stability sensor signals (steering angle, yaw rate, longitudinal acceleration, etc.). |
Possible Causes
- Wiring, terminals or connectors
- RCM
- ABS module
