After replacing the steering wheel.
After replacing the tilt steering column.
After replacing the steering gear assembly.
If the fault code C1515 is stored.
Note:
The power steering control module must be correctly initialized before a calibration of the steering wheel torque sensor is performed.
Test prerequisties:
The battery voltage should be >12 V.
Ignition on, engine off.
No stored fault codes except C1515 .
Vehicle on a flat and level surface.
Tires pointed straight ahead.
The steering wheel centered.
