Caution
Do not heat R-134a above 40
C
In most instances, moderate heat is required to
bring the pressure of the refrigerant in its container
above the pressure of the system when charging
or adding refrigerant.
A bucket or large pan of hot water not over 40
C
is all the heat required for this purpose. Do not
heat the refrigerant container with a blow torch
or any other means that would raise temperature
and pressure above this temperature. Do not weld
or steam clean on or near the system components
or refrigerant lines.
Caution
Keep R-134a containers upright when charging
the system.When metering R-134a into the refrigeration system
keep the supply tank or cans in an upright position.
If the refrigerant container is on its side or upside
down, liquid refrigerant will enter the system and
damage the compressor.
Caution
1. The leak detector for R-134a should be used
to check for refrigerant gas leaks.
2. Do not allow liquid refrigerant to touch bright
metal.
Refrigerant will tarnish bright metal and chrome
surfaces, and in combination with moisture can
severely corrode all metal surfaces.

INSPECTION
· Check the SRS-ECU and brackets for dents, cracks or
deformation.
· Check connectors and lock lever for damage, and
terminals for deformation
Caution
If a dent, crack, deformation or rust is discovered,
replace the SRS-ECU with a new one.
NOTE
For checking of the SRS-ECU other than described
above, refer to the section concerning troubleshooting.
(Refer to P.52B-5.)
AIR BAG MODULES AND CLOCK SPRING
Caution
1. Disconnect the battery (-) terminal and wait
for 60 seconds or more before starting
work. Furthermore, the disconnected
battery terminal should be covered with
tape to insulate it. (Refer to P.52B-3)
2. Never attempt to disassemble or repair the
air bag modules or clock spring.
If faulty, replace it.
3. do not drop the air bag modules or clock
spring or allow contact with water, grease
or oil.
Replace it if a dent, crack, deformation or
rust is detected.4. The air bag modules should be stored on a
flat surface and placed so that the pad
surface is facing upward.
Do not place anything on top of it.
5. Do not expose the air bag modules to
temperatures over 93° C.
6. After deployment of an air bag, replace the
clock spring with a new one.
7. Wear gloves and safety glasses when
handling air bags that have already
deployed.
8. An undeployed air bag module should only
be disposed of in accordance with the
procedures (Refer to P.52B-31.)

Exit conditions from the adjustment mode
The ETACS-ECU cancels the adjustment mode when any of the following conditions is satisfied:
•
Diagnosis control: OFF (Disconnect the MUT-II>)
•
Key reminder switch: ON (Pull out the ignition key.)
•
Ignition switch: Other than LOCK (OFF)
•
Door switch: ON (Open the door)
•
After the ETACS_ECU has entered the adjustment mode, no adjustment is made within 3 minutes (If
any adjustment is made within 3 minutes, the ETACS-ECU monitors an adjustment operation for
other 3 minutes.
•
Other warning buzzer(s) sounds
3.
Adjustment of functions
Function Adjustment procedure
Keyless entry answerback function When the transmitter lock switch is turned on twice continuously
within 2 seconds, the lock answerback function toggles on and off.
•
If the function toggles on, the buzzer sounds once (default con-
dition).
•
If the function toggles off, the buzzer sounds twice,
When the transmitter unlock switch is turned on twice continuously
within 2 seconds, the unlock answerback function toggles on and
off.
•
If the function toggles on, the buzzer sounds once (default con-
dition).
•
If the function toggles off, the buzzer sounds twice,
Initialisation of all the ETACS func-
tions (From deactivation to activa-
tion)When the tailgate switch remains on for more than 20 seconds, th
buzzer sounds twice and he answer-back function of the keyless
entry system is initialised.
The buzzer will sound in 10 seconds (indicating that the ETACS-
ECU enters the adjustment mode), but the washer switch must re-
mains off for 20 seconds in order to initialise all the functions.
If the tailgate switch remains on for more than 20 seconds without
entering the adjustment mode, the system enters the adjustment
mode in 10 seconds, but does not initialise all of the functions.

transmitter, but the room lamp or turn-signal lamp does
not flash or illuminate. (However, the room lamp oper-
ates normally when the doors are opened and closed.)Probable cause
If neither room lamp nor turn-signal lamp flash/illuminate, the
cause may be a malfunction of the ETACS-ECU or driver’s-side
door lock actuator.
If either room lamp or turn-signal lamp does not flash/illuminate,
the cause may be a malfunction of the room lamp circuit or turn-
signal lamp.•
