Pinpoint Test Ag: Stability Control Sensor Event Information Faults (C006X:68): Notes
Normal Operation and Fault Conditions
The RCM provides the stability/traction control system with acceleration sensor data over the HS-CAN 2. 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, C0064:68, and/or C0065:68 in memory. However, the RCM does not request that the IPC illuminate the airbag warning indicator when these faults are present.
PPT AG RCM 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. |
| C0064:68 | Roll Rate Sensor: Event Information | A fault is indicated when the roll rate sensor is transmitting data that is outside of the range expected by the RCM. |
| C0065:68 | Vertical Acceleration Sensor: Event Information | A fault is indicated when the vertical acceleration 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. |
Possible Causes
- Aggressive driving conditions or rough roads
- RCM mounting
- RCM
WARNING:
Incorrect repair techniques or actions can cause an accidental SRS deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.
NOTE:
Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE:
Only disconnect or reconnect SRS components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
NOTE:
Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.
NOTE:
The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
