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 

EXL-65, "Wiring Diagram"

.

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.

Is the inspection normal?

YES

>> GO TO 2

NO

>> Check the following:

• 10A fuse No. 5 located in the fuse block (J/B).

• Harness for open or short between headlamp aiming motor and fuse block (JB).

2.

CHECK HEADLAMP AIMING SWITCH SIGNAL FOR OPEN OR SHORT CIRCUIT

1. Disconnect headlamp aiming switch connector M140. 

2. Check continuity between the headlamp aiming switch harness connector and headlamp aiming motor

harness connector.

3. Check continuity between the headlamp aiming switch harness connector and ground.

Are continuity results as specified?

YES

>> GO TO 3

NO

>> Repair the harness or connector.

3.

CHECK HEADLAMP AIMING MOTOR GROUND CIRCUIT

Check continuity between headlamp aiming motor and ground.
