Pinpoint Test B : The Adjustable Steering Column Is Inoperative In One Or More Directions -- Using The Memory Set Switch Buttons/Using An RKE Transmitter/Using The Easy Entry/Exit Feature: Notes

Refer to Adjustable Steering Column for schematic and connector information.

Normal Operation 

When the desired memory position is selected using the memory SET switch or an RKE transmitter, the DSM communicates the desired steering column position in a message on the MS-CAN to the BCM. The BCM acts as a gateway module, relaying the message to the SCCM over the HS-CAN. The SCCM monitors the position of the adjustable steering column using Hall-effect type rotation sensors that are integral to the tilt and telescoping motors. The sensors provide a digital signal used by the SCCM to calculate the position of the steering column in relation to the full forward/rearward and full up/down positions. The SCCM uses these signals to store and recall memory positions, carry out easy entry/exit operations and to make sure the tilt and telescope motors do not stall against the steering column end of travel. If a tilt or telescope motor sensor DTC sets, the SCCM does not recall a programmed memory position or automatically position the steering column during the easy entry/exit operation. If a DTC sets for either sensor, the affected adjustable steering column motor operates in jog mode. Jog mode allows limited operation of the affected steering column motor using only the steering column control switch. When the steering column control switch is operated in jog mode, the steering column moves in the desired direction for one second, then stops. The steering column control switch must be released, then pressed again in order to move the steering column for an additional second.
