The Telescoping Steering Column Switch circuit provides an input to the Left (LH) Seat Control Module (SCM) when the switch is held closed in the in, button pressed toward the driver, or out, button pressed toward I/P, position. The SCM monitors a 12 volt signal applied to the steering column telescope forward switch signal circuit. When the steering column switch is closed in the In position, the column in 12 volt signal is grounded and pulled low within the SCM, indicating a column In request. The Diagnostic Trouble Code (DTC) sets when the steering column switch input, to the SCM, is active for more than 20 seconds.
