To avoid personal injury or death, on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, occupant classification system, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the Supplemental Restraint System (SRS). Failure to take the proper precautions could result in accidental airbag deployment.
The multi-function switch is secured with screws to the multi-function switch mounting housing on the left side of the steering column. The switch, its mounting provisions, and its electrical connections are all concealed beneath the steering column shrouds.
A single connector connects the switch to the vehicle electrical system.
The multi-function switch supports the following functions and features:
Continuous Wipe Modes - The control knob of the multi-function switch provides two continuous wipe switch positions, low speed or high speed.
Hazard Warning Control - The internal circuitry and hardware of the multi-function switch provide detent switching for activation and deactivation of the hazard warning system.
Headlamp Beam Selection - The internal circuitry and hardware of the multi-function switch provide detent switching for selection of the headlamp high or low beams.
Headlamp Optical Horn - The internal circuitry and hardware of the multi-function switch includes momentary switching of the headlamp high beam circuits to provide an optical horn feature (sometimes referred to as flash-to-pass), which allows the vehicle operator to momentarily flash the headlamp high beams as an optical signaling device.
Intermittent Wipe Mode - The control knob of the multi-function switch provides an intermittent wipe mode with multiple delay interval positions.
Turn Signal Control - The internal circuitry and hardware of the multi-function switch provide both momentary non-detent switching and detent switching with automatic cancellation for both the left and right turn signals.
Washer Mode - The control knob of the multi-function switch provides washer system operation when the knob is depressed towards the steering column.
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 unit must be replaced.
Removal & Installataion
The turn signal switch is incorporated into the Multi-Function Switch.
