INSPECTION PROCEDURE
PROCEDURE
1. CHECK FOR DTC
(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.
(b) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
OK:
DTC B2410 or B2411 output does not occur.
NG -- CHECK HARNESS AND CONNECTOR (HEADLIGHT SWIVEL ECU ASSEMBLY - BATTERY)
OK -- USE SIMULATION METHOD TO CHECK How To Proceed With Troubleshooting
2. CHECK HARNESS AND CONNECTOR (HEADLIGHT SWIVEL ECU ASSEMBLY - BATTERY)
(a) Disconnect the A46 headlight swivel 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.
4. CHECK HARNESS AND CONNECTOR (HEADLIGHT SWIVEL ECU ASSEMBLY - HEADLIGHT UNIT)
(a) Disconnect the A46 headlight swivel ECU connector.
(b) Disconnect the A49*1 or A50*2 headlight connector.
*1: for LH
*2: for RH
(c) Measure the resistance according to the value(s) in the table below.

for LH
for RH
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
5. INSPECT HEADLIGHT UNIT
(a) Remove the headlight unit Disassembly.
(b) Disconnect the headlight reflector (swivel motor) connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
for LH
for RH
Text in Illustration
NG -- REPLACE HEADLIGHT UNIT Disassembly
OK -- Continue to next step.
6. CHECK HEADLIGHT REFLECTOR (SWIVEL MOTOR) (OPERATION)
(a) Temporarily replace the headlight reflector (swivel motor) with a new or normally functioning one Disassembly.
(b) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
OK:
DTC B2410 or B2411 output does not occur.
NG -- REPLACE HEADLIGHT SWIVEL ECU ASSEMBLY Removal
OK -- END (REPLACE HEADLIGHT REFLECTOR [SWIVEL MOTOR]) Disassembly
