Diagnostic Overview
Normal Operation and Fault Conditions
The RCM provides the stability/traction control system with the yaw rate, roll rate, and lateral and longitudinal acceleration sensor data over a dedicated CAN . In addition to transmitting the data, the RCM monitors this data internally to make sure that the data is within an expected range.
If the data is outside of the expected range and a fault is detected, the RCM stores DTC C0061:68, C0062:68, C0063:68, and/or C006A:68 in memory. However, the RCM does not request that the IPC illuminate the airbag warning indicator when these faults are present.
DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C0061:68 | Lateral Acceleration Sensor: Event Information | A fault is indicated when the lateral acceleration sensor is transmitting data that is outside of the range expected by the RCM . |
| C0062:68 | Longitudinal Acceleration Sensor: Event Information | A fault is indicated when the longitudinal acceleration sensor is transmitting data that is outside of the range expected by the RCM . |
| C0063:68 | Yaw Rate Sensor: Event Information | A fault is indicated when the yaw rate sensor is transmitting data that is outside of the range expected by the RCM . |
| C006A:68 | Multi-axis Acceleration Sensor: Event Information | A fault is indicated when the multi-axis acceleration sensor is transmitting data that is outside of the range expected by the RCM . |
