Calibrate steering-angle sensor → 456000 Initialising and calibrating steering-angle sensor - chapter
on "Calibrating".

• 

If the steering column is replaced (new steering column), the electric steering column locking
mechanism (ELV) must be taught with the Piwis Tester in the PAS system, menu Learning functions
>> Teach ELV <<. You can get the necessary Teach Enable Code (TEC code) from IPAS or from
your importer using the vehicle identification number.

• 

Always replace the fastening screw for the universal joint of the steering column.

•

Steering shaft to steering gear

2. Put steering gear in centre position. Make sure that the clip for steering gear pinion is present (steering

shaft assembly aid). Mount the steering shaft (universal joint) to the steering gear in the correct position
using new hexagon-head bolt -arrow- .

Steering column tightening sequence

3. Insert the steering column and pay attention to the block teeth of the steering shaft (the steering shaft

can only paired be in one position! 2. worker required). Tightening sequence for mounting:

1.

- Pedal bearing axle on a/f 10 mm hexagon -2- (tightening torque 8 + 2 Nm (6 + 1.5 ftlb.))

2.

- Lock nut right -1a- (tightening torque 10 Nm (7.5 ftlb.)). Then lock nut for steering column -1b-

(tightening torque 46 Nm (34 ftlb.)).

3.

- Lock nut of upper mount -3- (tightening torque 46 Nm (34 ftlb.))

4. Install front underbody panel.

5. Install KESSY/PAS control unit.

6. Put steering column in the lowermost adjustment position and close the locking lever again. In this

position, fasten the strut to the structure (this allows the adjustment range to move smoothly in all
positions).

7. Install the steering-column switch and the trim panel from the steering-column switch → 9450

8. Carry out suspension alignment.

9. After the suspension alignment, with the position of the wheels >> straight ahead << calibrate the

steering-angle sensor on the measuring platform.

10. Carry out a test drive and check the operation (continuous easy steering movements, steering column

adjustment, electronic steering column lock).

Gefahr des Verlusts der Text-Bild-Zuordnung beim Ausdruck.

Aus technischen Gründen kann derzeit nicht ausgeschlossen werden, dass trotz
einwandfreier Darstellung auf dem Bildschirm beim Ausdruck der
Zusammenhang von Text und zugehörigem Bild verloren geht.

WARNING

Danger of losing text-figure correspondence when printing out.

For technical reasons, it can currently not be ruled out that the correspondence
between text and associated figure can be lost when it is printed out, even though
the display on the screen is correct.

• 

If the fault is not noticed, there is the danger that work will not be performed
correctly which can cause injury and damage.

• 

→ Therefore, always compare printouts with the screen display after printing them out. Correct
the printouts if they are faulty so that the content of the screen display matches that on the
printouts.
