Nissan Teana J32. Manual — part 511
EXL-14
< FUNCTION DIAGNOSIS >
[XENON TYPE]
AUTO LIGHT SYSTEM
• Turns the exterior lamp OFF with the ignition switch ACC or the light switch OFF.
*: The preset time is 45 seconds. The timer operating time can be set by CONSULT-III. Refer to
"HEADLAMP : CONSULT-III Function (BCM - HEAD LAMP)"
.
NOTE:
When any position other than the light switch AUTO is set, the auto light system function switches to the exte-
rior lamp battery saver function.

Description
BCM
• Detects each switch condition by the combination switch reading function.
• Judges the outside brightness from the optical sensor signal.
• Judges the OFF timing according to the vehicle condition.
• Judges the ON/OFF status of the exterior lamp and each illumination according to the
outside brightness and the vehicle condition.
Requests ON/OFF of each relay to IPDM E/R (with CAN communication).
IPDM E/R
Controls the integrated relay, and supplies voltage to the load according to the request
from BCM (with CAN communication).

HEADLAMP AIMING CONTROL SYSTEM (AUTO)
System Diagram
INFOID:0000000003774320
System Description
INFOID: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.

FRONT FOG LAMP SYSTEM
System Diagram
INFOID:0000000003773531
System Description
INFOID:0000000003773532
OUTLINE
Front fog lamp is controlled by combination switch reading function and front fog lamp control function of BCM,
and relay control function of IPDM E/R.
FRONT FOG LAMP OPERATION
• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the front fog light request signal to IPDM E/R with CAN communication according to the front
fog lamp ON condition.
Front fog lamp ON condition
- Front fog lamp switch ON
- Lighting switch 1ST, 2ND or AUTO (auto light function ON judgment)
• IPDM E/R turns the integrated front fog lamp relay ON, and turns the front fog lamp ON according to the
front fog light request signal.
• Combination meter turns the front fog lamp indicator lamp ON according to the front fog light request signal.
