No.1 AFS OFF LIGHT ILLUMINATES WHEN THE IGNITION IS SWITCHED TO ON [AFS (ADAPTABLE FRONT LIGHTING SYSTEM)]

id0903c6912100

1

AFS OFF light illuminates when the ignition is switched to ON
DESCRIPTION
•  The AFS OFF light illuminates continuously and the AFS does not operate (light-bending does not illuminate) when the ignition is switched ON regardless of whether the AFS OFF switch is turned ON or OFF.
POSSIBLE CAUSE
•  AFS OFF signal is always input to AFS control module
―  AFS OFF switch malfunction (stuck ON)
―  Short to ground circuit in wiring harness between AFS OFF switch terminal H (L.H.D.)/B (R.H.D.) and AFS control module terminal P
•  Auto leveling sensor signal circuit malfunction
―  Short to ground circuit in wiring harness between AFS control module terminal G and front auto leveling sensor terminal B
―  Short to ground circuit in wiring harness between AFS control module terminal E and rear auto leveling sensor terminal B
•  Instrument cluster malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
INSPECT IF MALFUNCTION IS IN AFS OFF SWITCH OR ELSEWHERE
•  Switch the ignition to off.
•  Disconnect the AFS OFF switch connector.
•  Switch the ignition to ON.
•  Verify the AFS OFF light condition.
•  Does the AFS OFF light turns off after illuminating for a few seconds immediately after the ignition switch is turned to the ON position (push start button switched to ON)?
Yes
Replace the AFS OFF switch.
(See AFS (ADAPTIVE FRONT LIGHTING SYSTEM) OFF SWITCH REMOVAL/INSTALLATION.)
No
Go to the next step.
2
INSPECT IF MALFUNCTION IS IN AFS OFF SWITCH SIGNAL WIRING HARNESS OR ELSEWHERE
•  Disconnect the AFS control module connector.
•  Verify the continuity between AFS OFF switch terminal H (L.H.D.)/B (R.H.D.) and body ground.
•  Is there continuity?
Yes
Repair or replace the malfunctioning part for short to ground circuit between AFS OFF switch terminal H (L.H.D.)/B (R.H.D.) and AFS control module terminal P.
No
Go to the next step.
3
INSPECT IF MALFUNCTION IS IN AUTO LEVELING SENSOR SIGNAL CIRCUIT OR ELSEWHERE
•  Verify the continuity between AFS control module terminal G/E and body ground.
•  Is there continuity?
Yes
Repair or replace the suspect wiring harness for a short to ground circuit.
No
Go to the next step.
4
INSPECT IF MALFUNCTION IS IN INSTRUMENT CLUSTER OR ELSEWHERE
•  Connect the M-MDS to DLC-2.
•  Select the active command “WL+IL” using the M-MDS and turn on the warning light in the instrument cluster.
•  Does the AFS OFF light illuminate?
Yes
Replace the AFS control module.
(See AFS (ADAPTIVE FRONT LIGHTING SYSTEM) CONTROL MODULE REMOVAL/INSTALLTION.)
No
Replace the instrument cluster.
