When “HEAD LAMP LO”, “HEAD LAMP HI” does not change depending on lighting switch
operation, refer to LT- 7 5 , "
System Description" . If above system is normal, replace AFS control
unit. Refer to LT- 9 4 , "
Removal and Installation of AFS Control Unit" .
3. CHECK STEERING ANGLE SENSOR
Check “STR ANGLE SIG” in “DATA MONITOR” when steering wheel
is driving straight and steering turn 90° to right or left.
OK or NG
OK >> GO TO 4.
NG >>

When steering is out of range while driving straight,
perform steering angle sensor adjustment. Refer to LT- 8 2 , "
WORK SUPPORT" .

When the function is normal while driving straight but the displayed value is different from
actual steering position with turning to right or left, replace steering angle sensor. Refer to LT-
94, "Removal and Installation of Steering Angle Sensor" .
