DTC B1041-14: Headlight Leveling Actuator Circuit Malfunction (Adaptive Front Lighting System): Notes
DTC B1041:14 (ADAPTIVE FRONT LIGHTING SYSTEM) DETECTION CONDITION AND POSSIBLE CAUSE
| System malfunction location |
Headlight leveling actuator circuit malfunction |
| Detection condition |
- Headlight leveling actuator circuit voltage of 3.2 V or less is detected for 5 s or more with the ignition switched ON (engine off or on).
|
| Fail-safe |
- The swivel actuator is moved to the center.
- The headlight leveling actuator is stopped at the position when the malfunction is determined.
|
| Possible cause |
- Front combination light (LH) connector or terminal malfunction
- Front combination light (RH) connector or terminal malfunction
- AFS control module connector or terminal malfunction
- Short to ground in wiring harness between the following terminals:
- AFS control module terminal B and front combination light (LH) terminal I
- AFS control module terminal H and front combination light (LH) terminal F (Without auto leveling sensor)
- AFS control module terminal P and front combination light (LH) terminal F (With auto leveling sensor)
- AFS control module terminal B and front combination light (RH) terminal I
- AFS control module terminal H and front combination light (RH) terminal F (Without auto leveling sensor)
- AFS control module terminal P and front combination light (RH) terminal F (With auto leveling sensor)
- Open circuit in wiring harness between the following terminals:
- AFS control module terminal B and front combination light (LH) terminal I
- AFS control module terminal H and front combination light (LH) terminal F (Without auto leveling sensor)
- AFS control module terminal P and front combination light (LH) terminal F (With auto leveling sensor)
- AFS control module terminal B and front combination light (RH) terminal I
- AFS control module terminal H and front combination light (RH) terminal F (Without auto leveling sensor)
- AFS control module terminal P and front combination light (RH) terminal F (With auto leveling sensor)
- Headlight leveling actuator malfunction
- AFS control module malfunction
