DTC/CIRCUIT DIAGNOSIS
B2503, B2504 SWIVEL ACTUATOR
Description
INFOID:0000000005244694
SWIVEL ACTUATOR
The swivel actuator is installed in the headlamp unit. The swivel actuator consists of the swivel motor and the
swivel position sensor.
SWIVEL MOTOR
• The swivel motor is the two-phase step motor.
• The swivel motor drives headlamp by exciting the two drive coils according to the drive signal from AFS con-
trol unit.
• The rotation direction of the swivel motor is changeable by changing the exciting pattern.
SWIVEL POSITION SENSOR
The swivel position sensor detects the headlamp swivel angle to transmit the swivel position sensor signal to
AFS control unit.
DTC Logic
INFOID:0000000005244695
DTC DETECTION LOGIC
• [B2503] Swivel actuator [RH]
• [B2504] Swivel actuator [LH]
*: initialization is not included.

condition
Possible cause
AFS control unit indicates an applicable DTC when detecting any of the follow-
ing conditions continuously for 2 seconds or more.
• AFS control unit-recognized swivel position differs extremely from the swivel
position sensor-input value while the swivel operating.
*
• The swivel position sensor signal does not change even though AFS control
unit transmits the swivel motor driving signal while the swivel operating
*
.
• The swivel motor short and open is detected while the swivel operating
*
.
• The swivel position sensor power supply is 6 V or more, or 4 V or less.
• The swivel position sensor signal is 0.25 V or less, or 4.75 V or more.

Diagnosis Procedure
INFOID:0000000005244696
1.
CHECK SWIVEL POSITION SENSOR SIGNAL INPUT
1.
Turn the ignition switch ON.
2.
Check the voltage between the AFS control unit harness connector and the ground.
Is the measurement value within the standard value?
YES
>> GO TO 2.
Less than the standard value >>GO TO 6.
Higher than the standard value>>GO TO 9.
2.
CHECK SWIVEL MOTOR
Check the swivel motor.
EXL-48, "Component Inspection"
.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Replace the front combination lamp.
3.
CHECK SWIVEL MOTOR OPEN CIRCUIT
1.
Turn the ignition switch OFF.
2.
Disconnect AFS control unit connector and the headlamp swivel actuator connector.
3.
Check continuity between the AFS control unit harness connector and the headlamp swivel actuator har-
ness connector.
