SAS (Steering Angle Sensor) Calibration
51
FastCheck
The steering angle sensor can be calibrated using the ‘SAS Calibration’ option. The
on screen instructions must be performed to ensure the calibration process is
correctly completed.
NOTE: The steering angle sensor should be calibrated after performing wheel
alignment or suspension adjustments.
Alfa Romeo/Fiat/Lancia vehicles
Steering angle sensor calibration
On some vehicles there may be a steering angle sensor calibration routine available
on both the ABS/TC/ESP control module and the Power Steering control module. If
this is the case the technician should always perform the routine via the Power
Steering control module. It will only be necessary to perform a steering angle sensor
calibration via the ABS/TC/ESP module on these vehicles if the sensor itself or/and
the ABS/TC/ESP control module have been replaced.
Longitudinal acceleration sensor calibration
This routine is necessary in the following situations:
1. The Longitudinal Acceleration Sensor has been replaced.
2. The ABS/TC/ESP control module has been replaced.
3. The ESP system is not behaving as it should. Resetting of this sensor can
sometimes cure strange ESP behaviour.
BMW/MINI Vehicles
NOTE: Procedure to switch the ignition ON for vehicles fitted with a start/stop, insert
the remote key-fob fully into the ignition slot then press the start/stop button once
(without any foot pedals depressed).
