LIGHTING: LIGHTING SYSTEM: B2412,B2413: Headlight Swivel Motor LH Malfunction
B2413 - Headlight Swivel Motor RH Malfunction
DESCRIPTION
The swivel actuator receives the signal from the AFS ECU to operate and sends the signal regarding the direction of the headlight and condition of the headlight swivel motor to the AFS ECU.

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 that the motor operates.
AFS (AFS ECU)
OK:
Swivel actuator operates.
Result:
C -- INSPECT HEADLIGHT ASSEMBLY
B -- REPLACE AFS ECU
A -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
2. INSPECT HEADLIGHT ASSEMBLY
(a) Disconnect the B11 and B2 headlight assembly connectors.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
LH Side (B2412)
RH Side (B2413):
HINT
Measure the resistance after the headlight has cooled.
NG -- REPLACE HEADLIGHT ASSEMBLY
OK -- Continue to next step.
3. CHECK WIRE HARNESS (HEADLIGHT ASSEMBLY - AFS ECU)
(a) Disconnect the A28 AFS ECU.
(b) Disconnect the B11 and B2 headlight connectors.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
LH Side (B2412)
RH Side (B2413)
NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
4. CHECK AFS ECU
(a) Disconnect the B11 and B2 headlight connectors.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:
LH Side (B2412)
RH Side (B2413)
Result:
C -- REPLACE AFS ECU
B -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
A -- Continue to next step.
5. REPLACE HEADLIGHT ASSEMBLY
(a) Temporarily replace the headlight assembly with a new or normally functioning one.
(b) Check that headlight assembly operates.
OK:
Return to normal operation.
NG -- REPLACE AFS ECU
OK -- END
