Suspension Stroke Sensor Circuit Troubleshooting

1. Measure the voltage between the headlight leveling control unit 16P connector No. 4 and No. 6 terminals, and No. 4 and No. 7 terminals while the suspension stroke sensor arm (A) is moved.

Is there about 0.5−4.5 V?

YES | - | Intermittent failure, the system is OK at this time. Check for loose or poor connection between the headlight leveling control unit and the front (or rear) suspension stroke sensor, if the connections are OK, replace the front (or rear) suspension stroke sensor.■
NO | - | Check for an open or a short in the wire between the headlight leveling control unit and the front (or rear) suspension stroke sensor, if the wires are OK, replace the front (or rear) suspension stroke sensor.■
