position. (Remove all loads in driver, passenger and trunk rooms.)
OK or NG
OK >> GO TO 3.
NG >> Perform LEVELIZER ADJUSTMENT. Refer to LT- 1 5 3 ,
"WORK SUPPORT (LEVELIZER ADJUSTMENT)" .
3. PERFORM STATE LEVELIZER ADJUSTMENT 2
Check if “LEV ACTR VLTG” changes approx. 3 seconds after lower-
ing vehicle height as low as approx.
0.5V from the value of “HI SEN
OTP RR” in “Data Monitor” at unloaded vehicle position. (Remove all
loads in driver, passenger and trunk rooms.)

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 , "
