HEADLAMP AIMING SYSTEM (MANUAL)
Description
INFOID:0000000009667167
The manual headlamp aiming system uses a headlamp aiming switch to adjust the axis of the headlamp aim-
ing motor. The headlamp aiming switch has four settings, each with a different resistance value. The head-
lamp aiming motor adjusts to the proper axis based off the position of the headlamp aiming switch.
Diagnosis Procedure
INFOID:0000000009667168
Regarding Wiring Diagram information, refer to
.
1.
CHECK HEADLAMP AIMING MOTOR POWER SUPPLY
1. Disconnect headlamp aiming motor harness connectors.
2. Turn ignition switch ON.
3. Check voltage between headlamp aiming motor harness connectors and ground.
