2.6.6.5.1 SENSORS FOR STEERING POSITION
Two curve sensors working on the principle of inductive proximity are used for sensing the steering lock.
The two sensors sense the position of the steering cylinder directly and without contact. They are insensitive
to dirt, wetness and temperature. When the steering lock is over 40°, the sensing area of the sensor is no
longer influenced by the steering cylinder and the sensor output is switched off. When the steering cylinder
is over the sensing area of the sensors (steering lock under 40°), the two sensors apply battery negative
voltage to the electronic traction control.
Both sensors are connected to the main wiring harness via a 3-pin connector (sensor X6 with 1B9 on left-
hand side, sensor X7 with 1B10 on right-hand side).
An LED is built into the sensor, which indicates the switching function of the sensor. The LED is not illuminated
when the steering cylinder is no longer over the sensing area.

SENSOR ADJUSTMENT:
The sensors require a clearance of 1 mm between the sensing area and the steering cylinder. Both sensors
can be set to the specified dimension with a feeler gauge after loosening the fastening nut.
