(unit side and connector side).
OK or NG
OK >> GO TO 2.
NG >> Repair the terminal and connector.
2. CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect the connector of steering angle sensor.
2. Check the resistance between the steering angle sensor harness connector terminals.
OK or NG
OK >> GO TO 3.
NG >> Repair the steering angle sensor branch line.
3. CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the steering angle sensor. Refer to BRC-48, "
Schematic"
(Models with VDC), LT- 7 9 , "Wiring Diagram — AFS —" (Models with AFS).
OK or NG
OK >>
Present error: Replace the steering angle sensor. Refer to BRC-91, "Removal and Installation"
(Models with VDC), LT- 9 4 , "REMOVAL" (Models with AFS).

Past error: Error was detected in the steering angle sensor branch line.

AFS (ADAPTIVE FRONT-LIGHTING SYSTEM)

Bending lamp (exclusive lamp for AFS) turn ON/OFF depending on the steering wheel angle and the vehi-
cle speed, when the headlamp LOW/HIGH lights, and the shift position is at any ranges except P.

Bending lamp supplies efficient light distribution for turning intersection and driving on the curves.

When turning to the left (right), bending lamp left (right) turn ON/OFF while driving forward or backward.

Power is supplied at all times

to ignition relay [located in IPDM E/R (Intelligent Power Distribution Module Engine Room)], from battery
direct,

through 15A fuse (No. 71, located in IPDM E/R)

to CPU (central processing unit) in IPDM E/R,

through 15A fuse (No. 78, located in IPDM E/R)

to CPU in IPDM E/R,

through 10A fuse (No. 38, located in fuse and fusible link block)

to AFS control unit terminal 6.
With the ignition switch in the ON or START position, power is supplied

to ignition relay (located in IPDM E/R),

through 10A fuse [No. 12, located in fuse block (J/B)]

to steering angle sensor terminal 3 and

to AFS control unit terminal 1.
Ground is supplied

to IPDM E/R terminals 38 and 60

through grounds E1 and E31,

to steering angle sensor terminal 2 and

to AFS control unit terminal 4

through grounds M71 and M72.
BENDING LAMP OPERATION
Bending lamp right/left turn ON depending on the steering wheel angle and the vehicle speed under the oper-
ating condition. Bending lamp right/left turn OFF when the steering wheel is returned to the straight.

Operation condition
