Stability/Traction Control System Sensor Calibration: Notes

When a new RCM is installed, the sensor(s) must be calibrated. The calibration procedure is required for the sensor(s) to learn the "zero-position" of the vehicle which means the vehicle must be on a level surface and must not be moving.

If a DTC is logged for any component of the AdvanceTrac® system, the DTC must be cleared or repaired before carrying out the calibration procedure. The need to calibrate is also indicated by the stability/traction control indicator flashing once every 2 seconds.

To carry out the calibration procedure, connect the scan tool, proceed to the IVD initialization sequence and follow the scan tool instructions.
