HEADLAMP AIMING CONTROL SYSTEM (AUTO)
System DiagramINFOID:0000000003774320
System DescriptionINFOID:0000000003774321
OUTLINE
 Headlamp aiming control system is controlled by auto levelizer control unit.
 Auto levelizer control unit controls the headlamp light axis height appropriately depending on the vehicle rear
height.
 Auto levelizer control unit detects the vehicle condition necessary for the aiming motor control with the fol-
lowing signals.
- Sensor lever signal (detected by the sensor lever)
- Tail lamp signal (inputted from IPDM E/R)
- Vehicle speed signal (8-pulse) (inputted from combination meter)
HEADLAMP AUTO AIMING OPERATION
 Auto levelizer control unit calculates vehicle pitch angle from sensor lever signal and determines the neces-
sary correction to compensate the deviation from standard light axis position.
 Auto levelizer control unit outputs aiming motor drive signal when operating conditions are satisfied.
Operating condition
- Ignition switch ON
- Tail lamp ON
 Auto levelizer control unit changes the aiming motor drive signal when any of the correcting condition is
detected. Output is maintained if other condition is detected.
Correcting condition- Tail lamp is turned ON.
- Vehicle posture becomes stable after the vehicle posture change is detected with the tail lamp ON and the
vehicle stopped.
- Vehicle speed is maintained with the tail lamp ON and the vehicle driven.
CAUTION:
Adjusted axis position may differ from the preset position although the headlamp auto aiming acti-
vates properly when the suspension is replaced or worn.
