Infiniti G35 (V35) Sedan. Manual — part 642
EXL-10
< FUNCTION DIAGNOSIS >
[XENON TYPE]
HEADLAMP SYSTEM
• When the headlamp high relay is turned ON, magnetic force is
applied to the high beam solenoid (1) by a current. The mobile
valve shade (3) is switched to the high beam position through the
actuator rod (2).
• When the headlamp high relay is turned OFF, the current stops.
The mobile valve shade returns to the low beam position automati-
cally.

Description
BCM
• Judges each switch condition by the combination switch reading function.
• Judges that the headlamp is turned ON according to the vehicle condition.
- Requests the headlamp relay (HI/LO) ON to IPDM E/R (with CAN communication).
- Requests the high beam indicator lamp ON to the combination meter [with CAN
communication (through unified meter and A/C amp.)].
IPDM E/R
Controls the integrated relay, and supplies voltage to the load according to the request
from BCM (with CAN communication).

AUTO LIGHT SYSTEM
System Diagram

System Description
INFOID:0000000000962401
OUTLINE
• Auto light system is controlled by each function of BCM and IPDM E/R.
Control by BCM
- Combination switch reading function
- Headlamp control function
- Auto light function
- Delay timer function
Control by IPDM E/R
- Relay control function
• Auto light system has the auto light function and the delay timer function.
- Auto light function turns the exterior lamps* and each illumination ON/OFF automatically according to the
outside brightness.
- When auto light system turns the exterior lamps ON with the ignition switch OFF, delay timer function turns
the exterior lamps OFF depending on the vehicle condition with the auto light function after a certain period
of time.
*: Headlamp (LO/HI), parking lamp, tail lamp, and front fog lamp (Headlamp HI and front fog lamp depend on
the combination switch condition.)
AUTO LIGHT FUNCTION
• BCM detects the combination switch condition with the combination switch reading function.
• BCM supplies voltage to optical sensor when the ignition switch is turned ON or ACC.
• Optical sensor converts outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.
• BCM judges outside brightness from the optical sensor signal and judges ON/OFF condition of the exterior
lamp and each illumination according to the outside brightness.
• BCM transmits each request signal to IPDM E/R with CAN communication according to ON/OFF condition
by the auto light function.
NOTE:
ON/OFF timing differs based on the sensitivity from the setting. The setting can be set by CONSULT-III. Refer
to
EXL-31, "HEADLAMP : CONSULT-III Function (BCM - HEAD LAMP)"
DELAY TIMER FUNCTION
BCM turns the exterior lamp OFF depending on the vehicle condition with the auto light function when the igni-
tion switch is turned OFF.
• Turns the exterior lamp OFF 5 minutes after detecting that any door opens (Door switch ON).
• Turns the exterior lamp OFF a certain period of time* after closing all doors (Door switch ON
→
OFF).
