Dynamic Steering Basic Setting: Notes
Special tools and workshop equipment required
- Steering Wheel Scales:VAS6458
- Vehicle Diagnostic Tester
- Wheel Alignment Computer
There are two choices for performing a basic setting on the dynamic steering:
The "quick access"
This procedure should be selected for the following activities if:
- The Active Steering Control Module -J792- was replaced,
- The Steering Angle Sensor -G85- was calibrated,
- The steering column was replaced,
- The steering wheel is at an angle when driving straight.
The "Complete Alignment"
This procedure should be selected for the following activities if:
- The suspension was adjusted during an axle alignment,
- The front axle toe was adjusted,
- The rear axle toe was adjusted,
- The vehicle suspension was changed, for example, changing from standard to sport suspension.
Both procedures are programmed into the axle alignment computer.
The respective procedure is performed automatically.
It is only necessary to select the appropriate program for the procedure that will be performed.

Before starting the basic setting, the Steering Angle Sensor -G85- must be calibrated using the :VAS6458 .
Before beginning the basic setting, check the DTC memory and correct any malfunctions present.
-- Connect the battery charger. Refer to BATTERY .
-- Connect the Vehicle Diagnostic Tester
-- Select the calibration procedure for dynamic steering in the alignment computer.
-- Install the quick clamps on all four wheels.
-- Install the measurement sensors on the front and rear wheels.
-- Perform wheel run-out compensation. Refer to WHEEL RUN-OUT COMPENSATION .
-- Position the wheels so they are straight according to the alignment computer.
Disregard the steering wheel position when doing this.
Only the display on the alignment computer is valid.
