HEADLAMP -CONVENTIONAL TYPE-PFP:26010
Component Parts and Harness Connector LocationEKS00P7H
System DescriptionEKS00P7I
The control of the headlamp system operation is dependent upon the position of the combination switch (light-
ing switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives
input requesting the headlamps (and tail lamps) illuminate. This input is communicated to the IPDM E/R (intel-
ligent power distribution module engine room) through the CAN communication. The CPU (central processing
unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. When energized, these relays
direct power to the respective headlamps, which then illuminate.

CONSULT-II Functions (BCM)EKS00P7Q
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II BASIC OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, and then turn
ignition switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “BCM” on “SELECT SYSTEM” screen.
If “BCM” is not indicated, refer toGI-50, "
CONSULT-II Data Link

HEADLAMP - DAYTIME LIGHT SYSTEM -PFP:26010
Component Parts and Harness Connector LocationEKS00Q7E
System DescriptionEKS00Q7F
The daytime light system is to illuminate headlamp low beam, clearance lamps, tail lamps and license plate
lamps while the engine is running.
When the engine is running, the BCM (body control module) receives the engine status signal. Then the BCM
sends the headlamp low beam request signal and the daytime light request signal to the IPDM E/R (intelligent
power distribution module engine room) through the CAN communication. As the IPDM E/R receives the
above request signals, its CPU (central processing unit) controls headlamp low relay to illuminate headlamp
low beam, clearance lamps, tail lamps and license plate lamps.
