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.

Possible Causes

ABS Calibration routine not carried out
RCM concern
EBB unit

AN1 CALIBRATE THE ABS (ANTI-LOCK BRAKE SYSTEM)

NOTE: The vehicle must be on level ground and at a complete standstill during ABS Calibration. Any vehicle movement results in a failed calibration.

NOTE: The IMU Calibration routine is also known as the IVD Initialization routine.

NOTE: The vehicle must be on level ground and at a complete standstill during IMU Calibration. Any vehicle movement results in a failed calibration.

Using a diagnostic scan tool, carry out the ABS Calibration routine, Follow the diagnostic scan tool instructions.

Does the sensor calibration routine pass successfully?

Yes	The condition causing the concern is no longer present. The concern was most likely caused by a failed sensor calibration or an non-calibrated sensor.
