INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (HEADLIGHT BEAM LEVEL CONTROL MOTOR - HEADLIGHT BEAM LEVEL)





(a) Disconnect the headlight assembly connector on the headlight beam level control motor side and the headlight beam level control ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
LH Side





RH Side






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

2. INSPECT HEADLIGHT BEAM LEVEL CONTROL MOTOR





(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:
LH Side





RH Side





HINT: Measure the resistance after the headlight has cooled down.

NG -- REPLACE HEADLIGHT BEAM LEVEL CONTROL MOTOR
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
