Combination Switch: Description and Operation
The multi-function switch (2) is located on the steering column, just below the steering wheel, within the Steering Column Control Module (SCCM).
The only visible components of the multi-function switch are the control stalk and control knob that extend through the SCCM on the left side of the
column. The remainder of the switch including its mounting provisions, its electrical connection, and the turn signal cancel actuator are concealed within
the SCCM.

The multi-function switch provides the vehicle operator with a control interface for the following functions:
-
Front Washer Control - The multi-function switch control knob provides a momentary position for front washer system operation.
-
Front Wiper Control - The multi-function switch control knob provides two continuous front wipe switch positions, low speed or high speed; and,
an intermittent front wipe mode with six delay interval positions.
-
Headlamp Beam Selection - The multi-function switch control stalk provides detent switching for selection of the headlamp high or low beams.
There is also an intermediate momentary position that allows the headlamp high beam circuits to be momentarily flashed to provide an optical
horn feature (sometimes referred to as flash-to-pass) as an optical signalling device.
-
Turn Signal Control - The multi-function switch control stalk provides momentary non-detent (lane change) switching and detent switching with
automatic cancellation for both the left and right turn signal lamps.
The multi-function switch cannot be adjusted or repaired. If any function of the switch is faulty, or if the switch is damaged, the entire switch must be
replaced as a unit. See: Relays and Modules/Relays and Modules - Steering and Suspension/Relays and Modules - Steering/Steering Column Control
