INSPECTION PROCEDURE

PROCEDURE

1. INSPECT HEADLIGHT BEAM LEVEL CONTROL MOTOR LH





(a) Disconnect the connector from headlight beam level control motor LH.
(b) Measure the resistance according to the value(s) in the table below.
Resistance:






NG -- REPLACE HEADLIGHT BEAM LEVEL CONTROL MOTOR LH
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (LEVEL CONTROL MOTOR LH - LEVEL CONTROL ECU)





(a) Disconnect the H3 connector of headlight beam level control motor LH and the H17 connector of the headlight beam level control ECU.
(b) Measure the resistance according to the value(s) in the table below.
Resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. INSPECT HEADLIGHT BEAM LEVEL CONTROL MOTOR RH





(a) Disconnect the connector from headlight leveling motor RH.
(b) Measure the resistance according to the value(s) in the table below.
Resistance:






NG -- REPLACE HEADLIGHT BEAM LEVEL CONTROL MOTOR RH
OK -- Continue to next step.
4. CHECK HARNESS AND CONNECTOR (LEVEL CONTROL MOTOR RH - LEVEL CONTROL ECU)





(a) Disconnect the H7 connector of headlight beam level control motor RH and the H17 connector of the headlight beam level control ECU.
(b) Measure the resistance according to the value(s) in the table below.
Resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
