Memory Position Programming and Recall

The SCCM  monitors steering column position using Hall-effect sensors that are integral to the tilt and telescoping motors. When a memory position is recalled through either the memory SET switch or the Remote Keyless Entry (RKE) transmitter, the SCCM  monitors the Hall-effect sensors and stops sending voltage to the steering column motors once the commanded memory position is reached. If the SCCM  receives a steering column switch input during a memory position recall function, the module stops the memory recall and responds to the new steering column switch position input.

When the RKE  transmitter is activated, a message is sent over the Medium Speed Controller Area Network (MS-CAN) to the Driver Seat Module (DSM). When the memory SET switch is pressed, the DSM  senses continuity to ground on the switch circuit. When the DSM  receives either the MS-CAN  message or the ground input through the switch circuit, it sends a message over the MS-CAN  to the Body Control Module (BCM). The BCM  acts as a gateway module, relaying the MS-CAN  message that was received from the DSM  to the SCCM  over the High Speed Controller Area Network (HS-CAN). The SCCM  then sends voltage over the appropriate circuit to the steering column tilt or telescoping motor to adjust the steering column position.
