HEADLAMP LEVELING SWITCH - EXPORT
The Headlamp Leveling Switch is located next to the headlamp switch (Fig 25) and is the primary controller of the headlamp leveling system. The leveling switch has three settings 0-2, "0" being the lowest, "2" being the highest headlight beam vertical setting.

With the rotation of the headlamp leveling switch control knob, voltage is adjusted at the headlamp leveling switch (rheostat). This signals the headlamp leveling motors (headlamp module mounted) to adjust the vertical headlamp beam pattern accordingly. The headlamps must be "ON" in order for the leveling system to function. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
