Longitudinal Accelerometer Calibration
This procedure may be necessary if the Longitudinal Accelerometer has been
replaced.

supply.
• Ensure the vehicle is placed on a level surface and that it remains stationary
throughout the whole procedure.
• Ensure the vehicle is stationary (0 km/h) on a level surface & no apply or release
command has been received.
• Make sure the parking brake module is correctly secured to the vehicle and that
the parking brake is applied.
Ensure the on screen instructions on the service tool are followed precisely and in
