DAYTIME RUNNING LIGHT SY STEM : System DiagramINFOID:0000000009463547
DAYTIME RUNNING LIGHT SYST EM : System DescriptionINFOID:0000000009463548
System Description
The daytime light system is equipped with a daytime light control that activates the daytime lights within the
front fog lamp assembly when the engine is operating. If the parking brake is applied, the daytime lights will
turn OFF. The daytime lights will turn ON when the parking brake is released.
OPERATION
The BCM monitors inputs from the parking brake swit ch and the combination switch (lighting and turn signal
switch) to determine when to operate the daytime light s ystem. The BCM sends a daytime light request to the
IPDM E/R via the CAN communication lines. The IPDM E/ R grounds the daytime light relay which in turn, pro-
vides power to the daytime lights.
FRONT FOG LAMP SYSTEM
FRONT FOG LAMP SYSTEM : System DiagramINFOID:0000000009463549
FRONT FOG LAMP SYSTEM : System DescriptionINFOID:0000000009463550
The front fog lamps are activated with the combination switch (lighting and turn signal switch). The lighting
switch signal to the BCM is monitored with the BCM combination switch reading function. When the fog lamps
are turned ON with the lighting switch, the BCM sends a front fog lamp request signal via CAN communication
lines to the IPDM E/R. The IPDM E/R grounds the front fog lamp relay coil to activate the front fog lamps.
FRONT FOG LAMP OPERATION
When the lighting switch is in front fog lamp ON position and also in 1st or 2nd position or AUTO position
(headlamp is ON), the BCM detects FR FOG ON and the HEAD LAMP 1, 2 ON or the AUTO LIGHT ON. The
BCM sends a front fog lamp request ON signal via the CAN communication lines to the IPDM E/R. The IPDM
E/R then turns ON the front fog lamp re lay sending power to the front fog lamps.

TURN SIGNAL AND HAZARD WARNING LAMPS : System DescriptionINFOID:0000000009463552
TURN SIGNAL OPERATION
When the combination switch (lighting and turn signal swit ch) is in LH or RH turn position with the ignition
switch in the ON position, the BCM receives input reques ting the turn RH or turn LH lamps to illuminate. The
BCM controls the turn signal power to the respective turn signal lamp. The BCM also sends a turn indicator
signal ON request via the CAN communication lines to the combination meter. The combination meter then
activates the appropriate turn signal indicator and audible buzzer.
HAZARD LAMP OPERATION
When the hazard switch is in the ON position, the BC M receives input requesting the hazard lamps illuminate.
The BCM controls the turn signal power to both the LH and RH turn signal lamps. The BCM sends a hazard
indicator signal ON request via the CAN communication lines to the combination meter. The combination
meter then activates both the LH and RH turn signal indicators and audible buzzer.

PARKING, LICENSE PLATE AND TA IL LAMPS : System DescriptionINFOID:0000000009463554
PARKING, LICENSE PLATE AND TAIL LAMPS OPERATION
When the lighting switch is in 1st or 2nd position, BCM detects the LIGHTING SWITCH 1st or 2nd POSITION
ON. The BCM sends a parking light ON request via the CAN communication lines to the IPDM E/R. The IPDM
E/R then activates the tail lamp relay which sends power to the parking and instrument illumination circuits.
EXTERIOR LAMP BATTERY SAVER CONTROL
With the combination switch (lighting and turn signal switch) in the 1st or 2nd position and the ignition switch is
turned from ON or ACC to OFF, the battery saver feature is activated.
Under this condition, the exterior lamps remain illumi nated for a period of time unless the lighting switch posi-
tion is changed. If the lighting switch position is changed, then the exterior lamps are turned off.

REFRIGERANT
4. Press UV lamp switch (5) and check A/C system for refrigerant leakage. (Where refrigerant leakage
occurs, fluorescent leak detec tion dye appears in green color.)
WARNING:
Do not look directly into UV lamp light source.
NOTE:
• For continuous operating time of UV lamp, follow the manufacturer operating instructions.
• Illuminate piping joints from different angles using UV lamp and check that there is no leakage.
• Use a mirror in area that is difficult to see to check refrigerant leakage.
• Refrigerant leakage from evaporator can be detected by soaking cotton swab or a similar material with
drain hose water and illuminating it using UV lamp.
• Dust, dirt and packing materials adhesive used for condenser, evaporator, and other locations may fluo- resce. Be careful not to misidentify leakage.
5. Repair or replace parts where refrigerant leakage occurs and wipe off fluorescent leak detection dye. NOTE:
Completely wipe off fluorescent leak detection dy e from gaps between parts, screw threads, and others
using a cotton swab or similar materials.
6. Use a UV lamp to check that no fluorescent leak detection dye remains after finishing work.
WARNING:
Do not look directly into UV lamp light source.
NOTE:
• For continuous operating time of UV lamp, follow the manufacturer operating instructions.
• Dust, dirt, and packing materials adhesive used for condenser, evaporator, and other locations may flu-
oresce. Be careful not to misidentify leakage.
CHECK REFRIGERANT LEAKAGE USING ELECTRICAL LEAK DETECTOR
WARNING:
Do not check refrigerant leakage while the engine is running.
CAUTION:
Be careful of the following it ems so that inaccurate checks or misidentifications are avoided.
• Do not allow refrigerant vapor, shop chemical vapor s, cigarette smoke or others around the vehicle.
• Always check refrigerant leakage in a low air flow en vironment so that refrigerant may not disperse
when leakage occurs.
1. Stop the engine.
2. Connect recovery/recycling/recharging equipment or manifold gauge set (J-39183-C) to A/C service
valve.
3. Check that A/C refrigerant pressure is 345 kPa (3.52 kg/cm
2, 50 psi) or more when temperature is 16 °C
(61 °F) or more. When pressure is lower than the specif ied value, recycle refrigerant completely and fill
refrigerant to the specified level.
NOTE:
Leakages may not be detected if A/C refrigerant pressure is 345 kPa (3.52 kg/cm
2, 50 psi) or less when
temperature is less than 16 °C (61 °F).
4. Clean area where refrigerant leakage check is performed and check refrigerant leakage along all surfaces of pipe connections and A/C system components us ing electrical leak detector (J-41995) probe.
CAUTION:
• Continue checking when a leakag e is found. Always continue and complete checking along all
pipe connections and A/C system components for additional leakage.
• When a leakage is detected, clean leakage area using compressed air and check again.
• When checking leakage of cooling unit inside, always clean inside of drain hose so that the
probe surface may not be exposed to water or dirt.
NOTE:
• Always check leakage starting from high-pressure side and continue to low-pressure side.
• When checking leakage of cooling unit inside, operate bl ower fan motor for 15 minutes or more at the
maximum fan speed while the engine is stopped, and then in sert electrical leak detector probe into drain
hose and hold for 10 minutes or more.
• When disconnecting shut-off valve that is connected to A/C service valve, always evacuate remaining
refrigerant so that misidentification can be avoided.
5. Repair or replace parts where refrigerant leak age is detected. (Leakage is detected but leakage area is
unknown.)
