XENON HEADLAMP
DescriptionINFOID:0000000009463586
OPERATION
Refer to EXL-9, "HEADLAMP SYSTEM : System Description".
PRECAUTIONS FOR TROUBLE DIAGNOSIS
• Installation or removal of the connecto r 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 malfunction can be traced directly to the electrical system, first check for items such as blown 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 (bul b socket harness, ballast harness) is prohibited.
• Immediately after illumination, the light int ensity and color will fluctuate, this is normal.
• When the bulb has reached the end of its lifetime, the br ightness may drop significantly, it may flash repeat-
edly, or the light may turn a reddish color.
Diagnosis ProcedureINFOID:0000000009463587
1.CHECK XENON BULB
Install a known good bulb to the applicable headlamp. Check that the headlamp operates.
Is the inspection result normal?
YES >> Replace the xenon bulb.
NO >> GO TO 2.
2.CHECK HID CONTROL UNIT
Install a known good HID control unit to the appl icable headlamp. Check that the headlamp operates.
Is the inspection result normal?
YES >> Replace HID control unit.
NO >> Inspection End.

DAYTIME LIGHT RELAY CIRCUIT
DAYTIME LIGHT RELAY CIRCUIT
DescriptionINFOID:0000000009463588
The BCM sends a daytime light request to the IPDM E/R via the CAN communication lines. The power flows
through fuse 43 located in IPDM E/R to the daytime li ght relay coil. When the IPDM E/R operates the daytime
light relay, power is sent to the daytime lamps.
Diagnosis ProcedureINFOID:0000000009463589
Regarding Wiring Diagram information, refer to EXL-39, "Wiring Diagram".
1.CHECK DAYTIME LIGHT RELAY VOLTAGE SUPPLY
1. Turn the ignition switch OFF.
2. Remove the daytime light relay.
3. Check the voltage between the daytime light relay harness connector E228 and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK DAYTIME LIGHT RELAY CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect IPDM E/R harness connector E18.
3. Check continuity between the IPDM E/R harness c onnector E18 and the daytime light relay harness con-
nector E228.
4. Check continuity between the IP DM E/R harness connector E18 and ground.
Is the inspection result normal?
YES >> Replace IPDM E/R. Refer to PCS-32, "Removal and Installation".
NO >> Repair or replace the harness or connector.
3.CHECK DAYTIME LIGHT RELAY CONTROL CIRCUIT
1. Turn the ignition switch OFF.
2. Check continuity between the IPDM E/R harness connector E201 and the daytime light relay harness
connector E228.

Check the daytime light relay. Refer to EXL-99, "Component Inspection"
.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Replace relay.
5.CHECK DAYTIME LIGHT CIRCUIT (OPEN OR SHORT TO GROUND)
1. Turn the ignition switch OFF.
2. Check continuity between the daytime light rela y harness connector E228 and the front fog lamp harness
connector.
3. Check continuity between the daytime light relay harness connector E228 and ground.
Is the inspection result normal?
YES >> GO TO 6.
NO >> Repair or replace the harness or connector.
6.CHECK DAYTIME LIGHT GROUND CIRCUIT FOR OPEN
1. Turn the ignition switch OFF.
2. Disconnect front fog lamp connector E234 or E237 in question.
3. Check continuity between the front fog lamp connector E234 or E237 and ground.
Is the inspection result normal?
YES >> Inspect daytime light bulb.
NO >> Repair or replace the harness or connector.
Component InspectionINFOID:0000000009463590
1. CHECK DAYTIME LIGHT RELAY
1. Turn ignition switch OFF.
2. Remove daytime light relay.
