DYNAMIC STEERING BASIC SETTING
Special tools and workshop equipment required
- Vehicle Diagnostic, Testing and Information System VAS 5051 B with corresponding diagnostic cable.
- Steering wheel level VAS 6458
- 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.
Note. 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.
