Circuit Description
WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The telescoping steering column switch circuit provides an input to the LH Seat Control Module (SCM) when the switch is held closed in the in, button pressed toward driver, or out, button pressed toward I/P, position. The SCM monitors a 12 volt signal applied to the steering column switch circuit. When the steering column switch is closed in the position, the column in 12 volt signal is grounded and pulled low within the SCM, indicating a column out request.
