When the front fog lamp switch is turned to ON with
the tail lamp or the headlamp on (the tail lamp switch
or the headlamp switch is ON), the fog lamp relay
turns on, and the fog lamps will illuminate.
If the tail lamps or the headlamps are turned off with
the lighting switch OFF while the fog lamps are on,
the front fog lamps turn off at the same time to
prevent unattended operation.
If the tail lamps are turned off by the headlamp
automatic shutdown function, the fog lamps turn off
at the same time. However, if the tail lamps illuminate
again, the fog lamps do not.
The front fog lamps are controlled by the Smart
Wiring System (SWS). For troubleshooting, refer to
respective Groups below.
•Not using SWS monitor: GROUP 54B, SWS

FRONT FOG LAMP AIMING CHECKM1542001100438
After setting the vehicles to the following condition,
adjust the front fog lamp aiming.
•Check that the tyre inflation pressure is at the
value indicated on the tyre pressure labels.
•Set the vehicle to the unladen condition and park
it on a level surface.
•Have a single person (approximately 75 kg) sit in
the driver’s seat.•Run the engine at a speed of 2000 r/min to fully
charge the battery.
Turn on the front fog lamps and check that the
illumination is within the standard value range.
Standard value: Illuminates to within 40
metres
CAUTION
For the fog lamp which is not being measured,
disconnect that fog lamp’s connector if possible
so that it does not illuminate while carrying out
the adjustment. Furthermore, make sure that the
light axis does not get shifted when
re-connecting the connector.
If the value is out of the standard value, insert the
screwdriver (+) through the aiming hole on the side
under cover to adjust by turning the adjusting gear
for fog lamp aiming.
NOTE: Horizontal adjustment is not possible.
In addition, the method of checking the light axis on a
screen (simple check) is given below. Item Standard value

Dimmer interior lamp control function
The room lamp off is delayed by ETACS-ECU. The
lamps off delay time vary according to the conditions.
The control details are as follows. The lamp delay off
Yes/NO and delay time can be set with the settings
(adjustment function). for adjustment methods and
adjustment details (post-adjustment operations).
•ADJUSTMENT PROCEDURE
•Not using SWS monitor: GROUP 54B,
P.54B-423.
•The room lamp lights up if the ignition switch is at
the "LOCK" (OFF) position and either of the
doors are opened (either of the door switches:
ON). At this time, if all doors are closed (all door
switches: OFF) then the lamp will gradually dim
down to lamps off in about 15 seconds.
NOTE: When the lamps are dimmed and the ignition
switch is turned ON or if the door is locked, then
the dimming operations stop and the lamps are
turned OFF.
•When the ignition switch is at the ON position and
one of the doors are opened (one of the door
switches: ON) then the room lamp will light up. At
this time, if all doors are closed (all door switches:
OFF) then the lamps will dim out.
•When the ignition key is pulled out the room lamp
lights up and then will dim out in 15 seconds. The
lamp will dim out if the ignition key is inserted
again and the door is locked while the timer is
activated.

lamps lights back up if the ignition switch is turned to
the ON position or either of the doors is opened
(either of the door switches: ON). The function

Rear Defogger operation
The defogger relay turns ON if the defogger switch
built-in the A/C-ECU is turned ON when the ignition
switch is in the "ON" position. When the defogger
relay turns ON, power is supplied to the defogger
and the defogger is activated. The defogger comes
with a timer function that causes the defogger switch
to automatically turn OFF in about 11 minutes after
the defogger switch is turned ON.

1. Run engine at 2,000 r/min. Check heater element
with battery at full.
2. Turn "ON" rear window defogger switch. Measure
heater element voltage with circuit tester at rear
window glass centre A. Condition is good if it
indicates about six volts.
3. If 12 volts is indicated at A, there is a break in the
negative terminals from A. Move test bar slowly to
negative terminal to detect where voltage
changes suddenly (0 volts).
4. If 0 volts is indicated at A, there is a break in the
positive terminals from A. Defect where the
voltage changes suddenly (12 volts) in the same
method described above.

DIAGNOSIS
STEP 1. Check the defogger and outside/inside
air selection damper control motor operation.
Q: Do the defogger and outside/inside air selection
damper control motor work normally?
YES :
Go to Step 2.
NO : Refer to Inspection procedure 9
"Malfunction of the A/C-ECU power supply
system
STEP 2. Check the blower motor operation.

YES :
Go to Step 3.
NO : Refer to Inspection procedure 5 "Blower fan
and motor do not turn P.55-29."
STEP 3. Check the A/C compressor.
Check the A/C compressor for compressor oil leaks.
Q: Is the check result satisfactory?
YES :
Go to Step 4.
NO : Replace the A/C compressor or the
expansion valve.
STEP 4. Connector check: B-114 A/C compressor
connector and C-123 engine-ECU connector
