CAUTION:AKS007MT

Installation or removal of the connector must be done with the lighting switch OFF.

When the lamp is illuminated (when the lighting switch is ON), do not touch the harness, HID control unit,
inside of the lamp, or the lamp metal parts.

To check illumination, temporarily install lamp in the vehicle. Be sure to connect power at the vehicle-side
connector.

If the error can be traced directly to the electrical system, first check for items such as burned-out fuses
and fusible links, broken wires or loose connectors, pulled-out terminals, and improper connections.

Do not work with wet hands.

Using a tester for HID control unit circuit trouble diagnosis is prohibited.

Disassembling the HID control unit or harnesses (bulb socket harness, ECM harness) is prohibited.

Immediately after illumination, the light intensity and color will fluctuate, but there is nothing wrong.

When the bulb has reached the end of its lifetime, the brightness may drop significantly, it may flash
repeatedly, or the light may turn a reddish color.
Xenon Headlamp Trouble DiagnosisAKS007MU
1. CHECK 1: XENON HEADLAMP LIGHTING
Install normal xenon bulb to corresponding xenon bulb headlamp, and check if lamp lights up.
OK or NG
OK >> Replace xenon bulb.

2. CHECK 2: XENON HEADLAMP LIGHTING
Install normal HID control unit to corresponding xenon headlamp, and check if lamp lights up.
OK or NG
OK >> Replace HID control unit.
NG >> GO TO 3.
3. CHECK 3: XENON HEADLAMP LIGHTING
Install normal xenon lamp housing assembly to corresponding xenon headlamp, and check if lamp lights up.
OK or NG
OK >> Malfunction in starter (boosting circuit) in xenon headlamp housing. (Replace xenon headlamp
housing assembly.)
NG >> INSPECTION END

DAYTIME LIGHT SYSTEM
Revision: 2004 November 2004 FX35/FX45
DAYTIME LIGHT SYSTEMPFP:284B2
Component Parts and Harness Connector LocationAKS007MZ
System DescriptionAKS007N0
DAYTIME LIGHT SYSTEM turns on Daytime Light Lamps while driving. Day Light Lamps are not turned on if
engine is activated with Parking Brake on. Take off Parking Brake to turn on Daytime Light Lamps. The lamps
turn off when Lighting Switch is in the 2ND position or AUTO position (Head Lamp is “ON”) and when Lighting
Switch is in the PASSING position. (Daytime Light Lamps are not turned off only by Parking Brake itself.)
An parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN commu-
nication line, and control daytime light system.
OUTLINE
Power is supplied at all times

through 10A fuse [No. 19, located in fuse block (J/B)]

to combination meter terminal 8

through 15A fuse [No. 22, located in fuse block (J/B)]

to BCM (body control module) terminal 42

through 50A fusible link (letter M, located in fuse and fusible link block)

to BCM (body control module) terminal 55

through 10A fuse [No. 36, located in fuse and fusible link block]

to daytime light relay terminals 2 and 5.
When the ignition switch is in ON or START position, power is supplied

through 10A fuse [No. 14, located in fuse block (J/B)]

to combination meter terminal 7

through 15A fuse [No. 1, located in fuse block (J/B)]

COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
AUTO LIGHT OPERATION
For auto light operation, refer to LT- 5 4 , "System Description" in “AUTO LIGHT SYSTEM”.
CAN Communication System DescriptionAKS007N1
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitAKS0080T
Refer to LAN-6, "CAN Communication Unit" .
