4. CHECK HEIGHT SENSOR SIGNAL AND AIMING MOTOR DRIVE SIGNAL
Remove height sensor link bracket mounting nuts (rear stabilizer side). For details, refer to LT- 1 9 2 , "
Removal
and Installation of Height Sensor" . Change sensor angle from the basic point of sensor angle 0 (standard
position) and check “HI SEN OTP RR” and “LEV ACTR VLTG” of “Data Monitor”.
With 18-inch wheel
NOTE:
1. Reference value. The value can be different from that of sensor angle and HI SEN OTP RR of maximum/minimum angle of auto
aiming operation depending on LEVELIZER ADJUSTMENT state.
2. Reference value. Approx.
1.5 V from the LEVELIZER ADJUSTMENT value.
With 19-inch wheel
NOTE:
1. Reference value. The value can be different from that of sensor angle and HI SEN OTP RR of maximum/minimum angle of auto
aiming operation depending on LEVELIZER ADJUSTMENT state.
2. Reference value. Approx.
1.2 V from LEVELIZER ADJUSTMENT value.
OK or NG
OK >> Auto aiming operation function is normal.
NG >>
When approx. 4.5 V or 0.5 V is not displayed on “HI SEN OTP RR” screen with sensor angle
approx. 45
or 45, check connector for connection, bend and loose fit. If it is normal, replace
height sensor. Refer to LT- 1 9 2 , "
Removal and Installation of Height Sensor" .
When “HI SEN OTP RR” value is normal but “LEV ACTR VLTG” value differs from maximum/
minimum angle of auto aiming operation, replace AFS control unit. Refer to LT- 1 9 1 , "
Removal
and Installation of AFS Control Unit" .
When “LEV ACTR VLTG” value is normal but operation range is irregular, check aiming motor
system circuit. Refer to LT- 1 8 7 , "

FRONT FOG LAMPPFP:26150
Component Parts and Harness Connector LocationNKS003R2
System DescriptionNKS003R3
The control of the fog lamps is dependent upon the position of the combination switch (lighting switch). The
lighting switch must be in the 2ND position or AUTO position (headlamp is ON) for front fog lamp operation.
When the lighting switch is placed in fog lamp position, the BCM (body control module) receives input signal
requesting the fog lamps to illuminate. When the headlamps are illuminated, this input signal is communicated
to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The
CPU (central processing unit) located in the IPDM E/R controls the front fog lamp relay coil. When activated,
this relay directs power to the front fog lamps.
