LIGHTING (EXT): LIGHTING SYSTEM: B2412,B2413: Headlight Swivel Motor LH Malfunction
B2413 - Headlight Swivel Motor RH Malfunction
DESCRIPTION
Each swivel motor receives a signal from the AFS ECU (headlight swivel ECU assembly) to operate and sends a signal indicating the direction of the headlight and condition of the headlight swivel motor to the AFS ECU (headlight swivel ECU assembly).

INSPECTION PROCEDURE
NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
PROCEDURE
1. CHECK FOR DTC
(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.
(b) Check for the DTCs Reading and Clearing Diagnostic Trouble Codes.
OK:
DTC B2412 or B2413 is not output.
NG -- PERFORM ACTIVE TEST USING TECHSTREAM
OK -- USE SIMULATION METHOD TO CHECK How To Proceed With Troubleshooting
2. PERFORM ACTIVE TEST USING TECHSTREAM
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Start the engine.
(e) Enter the following menus: Body Electrical / AFS / Active Test.
(f) Check that the swivel motors operate.
AFS
OK:
Swivel motors operate normally.
NG -- CHECK HARNESS AND CONNECTOR (BATTERY - AFS ECU)
OK -- Continue to next step.
3. REPLACE HEADLIGHT SWIVEL MOTOR (HEADLIGHT REFLECTOR)
(a) Temporarily replace the headlight swivel motor (headlight reflector) with a new or normally functioning one Components.
(b) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
OK:
DTC B2412 or B2413 is not output.
NG -- REPLACE AFS ECU (HEADLIGHT SWIVEL ECU ASSEMBLY) Components
OK -- END
4. CHECK HARNESS AND CONNECTOR (BATTERY - AFS ECU)
(a) Disconnect the A53 AFS ECU (headlight swivel ECU assembly) connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Text in Illustration
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (AFS ECU - BODY GROUND)
(a) Disconnect the A53 AFS ECU (headlight swivel ECU assembly) connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Text in Illustration
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
6. CHECK HARNESS AND CONNECTOR (AFS ECU - HEADLIGHT ASSEMBLY)
(a) Disconnect the A53 AFS ECU (headlight swivel ECU assembly) connector.
(b) Disconnect the A18 or A26 headlight assembly connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
LH Side (B2412)
RH Side (B2413)
Text in Illustration
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
7. INSPECT AFS ECU (HEADLIGHT SWIVEL ECU ASSEMBLY)
(a) Reconnect the A53 AFS ECU (headlight swivel ECU assembly) connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
LH Side (B2412)
RH Side (B2413)
Text in Illustration
NG -- REPLACE AFS ECU (HEADLIGHT SWIVEL ECU ASSEMBLY) Components
OK -- Continue to next step.
8. INSPECT HEADLIGHT UNIT
(a) Remove the headlight unit Components.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
LH Side (B2412)
RH Side (B2413)
Text in Illustration
NG -- REPLACE HEADLIGHT UNIT Components
OK -- Continue to next step.
9. REPLACE HEADLIGHT SWIVEL MOTOR (HEADLIGHT REFLECTOR)
(a) Temporarily replace the headlight swivel motor (headlight reflector) with a new or normally functioning one Components.
(b) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.
OK:
DTC B2412 or B2413 is not output.
NG -- REPLACE AFS ECU (HEADLIGHT SWIVEL ECU ASSEMBLY) Components
OK -- END
