WARNING
Danger of injury and damage to property due to malfunctions in the PSM control range if the steering angle
sensor is not calibrated or is calibrated incorrectly!
•
Calibrate steering angle sensor with wheels in straight−ahead position with the Porsche System Tester
2!
The steering angle sensor actual value must be checked after a suspension alignment which resulted in
•
no changes being made to the wheel alignment values!
Note
•
The steering angle sensor must be calibrated if the previous wheel alignment values (on rear and/or
front axle) were changed! => Steering angle sensor
Preliminary work:
1. Check whether the steering wheel is displaced with respect to the steering gear.
2. To do this, centre the steering gear as described below.
3. Turn wheels to the straight−ahead
position.
4. Then readjust the front wheel alignment, if necessary, until pin No. −2− in driver No. −1− and the lug on
the steering gear housing No. −4− line up.
No. −3− is the desired breaking point for pins in new steering gears. The (new) pin No. 2 is inserted into
driver No. 1 and lies with its underside within the recess of lug No. 4. This locks the steering gear in the
centre position. After installation of a new steering gear, the lower part of the pin is sheared off (at the desired
breaking point No. −3− ) by turning the steering wheel. The upper part of the pin remains in the driver.
If necessary, reposition the steering wheel. When doing this, seek the best position.
WARNING
A triggering of the airbag (malfunction in the airbag system) caused by improper work on airbag components
cannot be ruled out! In the case of such a malfunction, an unsuitable steering wheel holder could cause injury
or damage!
•
Use only steering wheel holders which do not project into the area of the airbag unit!
•
Observe safety regulations when working with airbag vehicles!' 69 Passenger protection
5. Clamp steering wheel in centre position with steering wheel holder.
