Pinpoint Tests: Notes

The Adjustable Steering Column is Inoperative in One or More Directions Using the Steering Column Control Switch 

Refer to Wiring Diagrams Cell 128 for schematic and connector information.

Normal Operation and Fault Conditions 

The SCCM receives input directly from the steering column control switch then sends a message along the HS-CAN2 to the GWM indicating the desired steering column movement. The GWM sends the message to the DSM along the MS-CAN which activates the tilt and telescopic (reach) motors depending on the message received.

A failure of the steering column control switch, circuits, motor or module cause the power adjustable column to become inoperative and a DTC may be set in the SCCM and the DSM.
