Pinpoint Test An: Stability Control Sensor Initialization Fault
Normal Operation and Fault Conditions
The ABS module monitors various inputs and compares the values to what should be expected. If the values received are out of range or not what is expected, the ABS module sets a DTC. When a new ABS module or RCM is installed, the stability control sensors in the RCM must be initialized. This is accomplished using a diagnostic scan tool to run the ABS Calibration routine.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS C0061:54 | Lateral Acceleration Sensor: Missing Calibration | Sets when the ABS module detects the stability sensors in the RCM have not been calibrated or the calibration has been lost. |
| ABS C0062:54 | Longitudinal Acceleration Sensor: Missing Calibration | Sets when the ABS module detects the stability sensors in the RCM have not been calibrated or the calibration has been lost. |
| ABS C006A:95 | Multi-axis Acceleration Sensor: Incorrect Assembly | The sensor cluster sends an identification number to the ABS module when the ABS Calibration routine is carried out. This identification number is then shared between the modules when the ignition is set to ON. This DTC sets when the sensor cluster identification number does not match the last valid identification number and the new valid sensor identification number. |
