WIRING DIAGRAM





INSPECTION PROCEDURE
HINT: Perform a visual check of the headlight (swivel motor) before replacing it.

PROCEDURE

1. CHECK FOR DTC
(a) Clear the DTC Reading and Clearing Diagnostic Trouble Codes.
(b) Check for DTC Reading and Clearing Diagnostic Trouble Codes.
OK:
DTC B2410 or B2411 output does not occur.
NG -- CHECK HARNESS AND CONNECTOR (BATTERY - AFS ECU)
OK -- USE SIMULATION METHOD TO CHECK
2. CHECK HARNESS AND CONNECTOR (BATTERY - AFS ECU)




(a) Disconnect the A37 ECU connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:






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

3. CHECK HARNESS AND CONNECTOR (AFS ECU - BODY GROUND)




(a) Disconnect the A37 ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






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

4. CHECK HARNESS AND CONNECTOR (AFS ECU - HEADLIGHT)




(a) Disconnect the A37 ECU connector.
(b) Disconnect the B3 and B13 light connectors.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:

for LH





for RH





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

5. CHECK HEADLIGHT ASSEMBLY




(a) Disconnect the B3 and B13 connectors.
(b) Disconnect the swivel motor connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:

for LH





for RH





NG -- REPLACE HEADLIGHT ASSEMBLY
OK -- Continue to next step.

6. CHECK HEADLIGHT SWIVEL MOTOR (OPERATION)
(a) Temporarily replace the headlight swivel motor with a new or normally functioning one Disassembly.
(b) Check for DTC Reading and Clearing Diagnostic Trouble Codes.
OK:
DTC B2410 or B2411 output does not occur.
NG -- REPLACE AFS ECU
OK -- END (REPLACE HEADLIGHT SWIVEL MOTOR)
