B2878

Circuit Description
The steering column module receives ground inputs from contacts inside the tilt/telescoping switch. The steering column module then supplies battery voltage to the tilt motor UP or DOWN circuit, or, the telescope motor IN or OUT circuit depending on which direction of movement is requested. Both motors are reversible and the circuits are simply reversed to accomplish movement in opposite directions.

Conditions for Running the DTC
The steering column module is ON.

Conditions for Setting the DTC
The steering column module detects a switch input for more than 30 consecutive seconds after movement of the motor in the requested direction has stopped.

Action Taken When the DTC Sets
- The motor that is being driven by the failed switch will be deactivated.
- Memory recall functions will be disabled.

Conditions for Clearing the DTC
- The DTC will clear from current status when the failed switch input is no longer active.
- Use a scan tool.

Diagnostic Aids
An intermittently stuck switch can cause this DTC to set. Refer to Testing for Intermittent and Poor Connections in Diagrams/Diagnostic Aids.
