Tilt/Telescoping Soft Stops

After replacement of the driver position module (DPM), it is necessary to program the tilt/telescoping soft stops. Each soft stop is a programmable end of travel that is set approximately 1.3 cm (0.5 in) from the mechanical end of travel. The steering column has a soft stop set at each end of the telescoping in/out and tilt up/down movement. The system uses soft stops to prevent wear on the system by ensuring that the steering column movement stops before it reaches its mechanical end of travel in any direction. The soft stops are initially programmed at the factory. The stop positions may be reprogrammed, which is necessary any time the DPM, the tilt actuator or telescope actuators replaced, as described in the following procedure.
