Lamps Lighting - Exterior
Fig. 46: Left Multifunction Switch

The left (lighting) multi-function switch is located on the left side of the steering column, just below the steering wheel. This switch is the primary control for the interior and exterior lighting systems. The only visible components of the switch are the control stalk (2), control knob (1) and control sleeve (3) that extend through the steering column shrouds 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 beneath the shrouds.

Fig. 47: Steering Control Module

The switch housing (2) and controls (1) are constructed of molded black plastic. Each of the switch controls has white International Control and Display Symbol graphics applied to it, which clearly identify its many functions. A single screw (7) through a mounting tab integral to the back of the switch housing, and a slide tab integral to the bottom of the switch housing secure the switch to the mounting bracket integral to the clockspring (3).

The Steering Control Module (SCM) is internal to the switch housing. The switch outputs are internally connected directly to the SCM. A single connector receptacle containing seven terminal pins is integral to the inboard end of the switch housing and connects the right multi-function switch (6) through a jumper wire harness (5) directly to the SCM. An integral connector receptacle on the back of the switch housing connects the SCM to the vehicle electrical system through a dedicated take out and connector of the instrument panel wire harness.

The left multi-function switch provides the vehicle operator with a control interface for the following exterior lighting functions:

  • Automatic Headlamps - For vehicles so equipped, the left multi-function switch control knob provides detent switching for the optional automatic headlamps.
  • Front Fog Lamps - For vehicles so equipped, the left multi-function switch control knob provides detent switching for the optional front fog lamps.
  • Headlamps - The left multi-function switch control knob provides detent switching for the headlamps.
  • Headlamp Beam Selection - The left multi-function switch control stalk provides detent switching for selection of the headlamp high or low beams.
  • Headlamp Optical Horn - The left multi-function switch control stalk includes momentary switching of the headlamp high beam circuits to provide an optical horn feature (sometimes referred to as flash-topass), which allows the vehicle operator to momentarily flash the headlamp high beams as an optical signalling device.
  • Park Lamps - The left multi-function switch control knob provides detent switching for the park lamps.
  • Rear Fog Lamps - For vehicles so equipped, the left multi-function switch control knob provides detent switching for the optional rear fog lamps. Rear fog lamps are optional only for vehicles manufactured for certain export markets, where they are required.
  • Turn Signal Control - The left multi-function switch control stalk provides both momentary non-detent switching and detent switching with automatic cancellation for both the left and right turn signal lamps.

The left multi-function switch also provides the vehicle operator with a control interface for the following interior lighting functions:

  • Interior Lamps Defeat - The left multi-function switch control ring provides detent switching to defeat the illumination of all interior courtesy lamps when a door or the liftgate is opened.
  • Interior Lamps On - The left multi-function switch control ring provides detent switching to illuminate all interior courtesy lamps simultaneously.
  • Panel Lamps Dimming - The left multi-function switch control ring provides simultaneous adjustable control of the illumination intensity of all instrument panel lighting at one of six available illumination intensity levels.
  • Parade Mode - The left multi-function switch control ring provides detent switching for a parade mode that maximizes the illumination intensity of all instrument panel lighting for visibility when driving in daylight with the exterior lamps turned on.

The left multi-function switch cannot be adjusted or repaired. If any function of the switch is ineffective, or if the switch is damaged, the entire switch unit must be replaced. The clockspring (with the multi-function switch mounting bracket), the left multi-function switch (with the SCM), the right multi-function switch and the jumper wire harness are each available for separate service replacement.

    Operation
    The left (lighting) multi-function switch uses resistor multiplexing to control the many functions and features it provides using a minimal number of hard wired circuits. The switch receives clea ...
