Steering Column: Description and Operation
Steering column, electrically adjustable
An electrically adjustable steering column is available as an option.
The control module for steering column-belt height adjustment -J352- has no self-diagnosis capability.
In the event of problems, use wiring diagram to perform fault-finding.
Description of operation:
The automatic function simultaneously adjusts seat belt and steering column (vertically/horizontally).
Safety functions:
To avoid overloading vehicle battery, the positioning motors are not activated simultaneously on implementing automatic adjustment but rather in quick succession.
If voltage drops below 10.5 V, the motors are adjusted separately in turn.
Blockage detection (1.5 s) and running time error (max. 30 s/motor) result in direct deactivation of the motor concerned.
Easy-entry facility (adjustment of steering column)
To make it easier to get into and out of vehicle, breaking of S contact (ignition off) causes steering column to move to its horizontal and tilt end position and, to return to its original position when S contact is made (ignition on).
Switching off easy-entry facility switch completely deactivates easy-entry function or immediately terminates current adjustment process.
Special features
Only belt height is adjusted if P button is pressed with S contact off. Steering column only assumes memory position with "S contact on".
If entry position has been altered beforehand, steering column does not return to original position with "S contact on" for example by way of manual adjustment
