INSPECTION PROCEDURE

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM

(a) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG) and turn the Techstream on.

(c) Select the item below in the ACTIVE TEST and then check the motor operation.

AFS (AFS ECU)





OK:

Headlight beam leveling control actuator is operated.

Result:





C -- CHECK WIRE HARNESS (HEADLIGHT BEAM LEVEL CONTROL MOTOR - AFS ECU)

B -- REPLACE AFS ECU

A -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE

2. CHECK WIRE HARNESS (HEADLIGHT BEAM LEVEL CONTROL MOTOR - AFS ECU)





(a) Disconnect the B11 and B2 headlight assembly connectors.

(b) Disconnect the A28 AFS ECU connector.

(c) Measure the resistance according to the value (s) in the table below.

Standard resistance:

LH Side (B2417)





RH Side (B2418):





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

3. INSPECT HEADLIGHT LEVELING MOTOR (LH or RH)

(a) Measure the resistance of the connector.





Standard resistance:

RH Side (B2418)





LH Side (B2417)





Result:





C -- REPLACE HEADLIGHT ASSEMBLY LH OR HEADLIGHT ASSEMBLY RH

B -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE

A -- REPLACE AFS ECU
