Headlamp Leveling Motor (Export): Description
The Headlamp Leveling System allows the driver to adjust the headlamp beam pattern from the interior of the vehicle to compensate for passenger or cargo load. Only the vertical axis of the headlamp beam can be adjusted.
A headlamp leveling switch is located on the instrument panel Accessory Switch Bank Module (ASBM), and controls the headlamp leveling motors found on the headlamp unit. The headlamp leveling switch has four settings 0-3, 0 being the highest, 3 being the lowest headlight beam vertical setting.
When performing a headlamp beam pattern alignment on a vehicle equipped with headlamp leveling, be certain the headlamp leveling switch is in the "0" position before starting. Failure to do so will result in an incorrect headlamp unit alignment.
