(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 How To Proceed With Troubleshooting

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.

OK -- Continue to next step.

5. INSPECT HEADLIGHT ASSEMBLY





(a) Remove the headlight assembly Removal.

(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 Removal
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.
