3. Check PIN #1 for battery voltage. If no voltage is present, trace circuit until open or short is found. Refer to Wiring Diagrams for complete schematic.
4. Check PIN #2 for ground. If ground is not present, trace circuit until open or short is found. Refer to Wiring Diagrams for complete schematic.
5. Check PIN #3 for headlamp leveling sense voltage (2.83 - 8.60 V). If voltage is incorrect or not present, trace circuit until open or short is found. (Refer to ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/HEADLAMP LEVELING SWITCH - DIAGNOSIS AND TESTING) for further information.
6. If no open or short is found, and headlamp leveling system is still inoperative, replace the headlamp leveling motor (Refer to ELECTRICAL/ LAMPS/LIGHTING - EXTERIOR/HEADLAMP LEVELING MOTOR - REMOVAL).
