B2904

Circuit Description
The Steering Column Tilt/Telescoping Module (SCCM) receives an input from the tilt/telescope switch
when the switch is pressed. The SCCM recognizes this input and supplies battery voltage and ground 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 voltage and ground applied to the circuits is simply reversed to accomplish movement in opposite directions.

Conditions for Running the DTC
With the ignition switch ON, the SCCM checks the switch inputs every 30 seconds regardless of source voltage.
Conditions for Setting the DTC
When the SCCM detects two simultaneous inputs for more than two seconds, the module considers the inputs invalid and sets the DTC.

Action Taken When the DTC Sets
- The SCCM no longer moves the steering column in the direction of the invalid inputs.
- The SCCM continues to respond to inputs from the other manual switches.

Conditions for Clearing the DTC
- The SCCM no longer receives two simultaneous switch inputs.
- Use the scan tool to clear the DTC.
- Use the On-Board Diagnostics to clear the code.

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