Pinpoint Test G : Stability Control Sensor Signal Failure DTCS: Notes
Refer to Vehicle Dynamic Systems for schematic and connector information.
Normal Operation and Fault Conditions
The RCM measures vehicle yaw rate, lateral acceleration, longitudinal acceleration and roll rate, then 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, longitudinal accelerometers and roll rate sensor are contained in the RCM.
A failure of the private HS-CAN, RCM or the internal sensors causes the ABS module to set one or more Diagnostic Trouble Codes (DTCs). An incorrectly installed RCM sends invalid information to the ABS module, which also causes a DTC to set.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C0061:28, C0062:28, C0063:28, C0064:28 | Lateral Acceleration, Longitudinal Acceleration, 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 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, C0064:64 | Lateral Acceleration, Longitudinal Acceleration, 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 (steering angle, yaw rate, longitudinal acceleration or lateral acceleration). |
| U0151:00 | Lost Communication With Restraints Control Module: No Sub Type Information | This DTC sets in continuous memory and on-demand if the expected RCM messages such as yaw rate sensor, lateral accelerometer, longitudinal accelerometer or roll rate sensor are missing for more than 5 seconds. |
| U0452:86 | Invalid Data Received from Restraints Control Module: Signal Invalid | This DTC sets in continuous memory and on-demand if one or more of the stability sensors inside the RCM fails and the sensor signal provided does not match other stability control sensor input. |
