ASSEMBLY SERVICE POINTS
ABATTERY INSTALLATION
Install a new battery with (+) side upward.
Battery required for replacement:
Lithium battery CR1216
SECRET CODE REGISTRATION METHOD
Each individual secret code is registered inside
the transmitter, and so it is necessary to register
these codes with the EEPROM inside the receiver
in the following cases.

When either the transmitter or receiver is
replaced;

If it appears that a problem is occurring because
of faulty registration of a code.
A maximum of two different codes can be stored
in the memory area of the EEPROM (two different
transmitters can be used). When the code for the
first transmitter is registered, the previously-regis-
tered codes for two transmitters are cleared.
Therefore, if you are using two transmitters or are
adding a second transmitter, the codes for both
transmitters must be registered at the same time.
Before beginning with the registration, check that
the doors lock normally when the key is used.
1. Connect the MUT-II to the diagnosis connector.
NOTE
This will connect terminal (1) of the diagnosis
connector to earth, and the system will be in
secret code registration standby mode.
Caution
Always turn the ignition switch to OFF before
connecting and disconnecting the MUT-II.
2. Close all the doors.
3. Turn the ignition switch to ACC and then back
to OFF.NOTE
The doors will lock and unlock once at this
time and the system will switch to registration
mode.
4. Press the transmitter switch, and then press
it two times within 10 seconds of the first press.
This will register the code.
5. After registration is completed, the doors will
be automatically locked and unlocked once.
6. If you are using two transmitters or have added
a second transmitter, the same registration
procedure should be carried out for the second
transmitter, and it should be carried out within
one minute after registration of the code for
the first transmitter has been completed. After
the second registration is completed, the doors
will be automatically locked and unlocked once.
7. Registration mode will be cancelled if one of
the following conditions is met.

When the secret codes for two transmitters
have been registered;

When 1 minute has passed after
registration mode started;

If the MUT-II is disconnected (the earth
connection is broken);

If the ignition switch is turned to ON;

If any of the doors are opened;
8. After registration is completed, carry out the
following to check if the keyless entry system
is operable properly.

Remove the ignition key.

Close all the doors.

SRS WARNING LAMP INSPECTION
1. Check to be sure that the SRS warning lamp illuminates
when the ignition switch is in the ON position.
2. Check to be sure that it illuminates for approximately
7 seconds and then switches off.
3. If the above is not the cause, inspect the diagnosis codes.
INSPECTION CHART FOR TROUBLE SYMPTOMS
Get an understanding of the trouble symptoms and check according to the inspection procedure chart.
Trouble symptomInspection procedure No.Reference page
Communication with
MUT-II is not possible.Communication with all systems is not
possible.152B-14
Communication is not possible with
SRS only.252B-15
When the ignition key is turned to “ON” (engine stopped), the
SRS warning lamp does not illuminate.Refer to diagnosis code No.43.52B-12
After the ignition switch is turned to ON, the SRS warning lamp
is still on after approximately 7 seconds have passed.Refer to diagnosis code No.43.52B-12
INSPECTION PROCEDURE FOR TROUBLE SYMPTOMS
Inspection Procedure 1
Communication with MUT-II is not possible. (Communica-
tion with all systems is not possible.)
Probable cause
The cause is probably a power supply system (including earth circuit) of the diagnosis
line.
Malfunction of connectors

Malfunction of wiring harness
Refer to GROUP 13A – Troubleshooting.

SRS – Troubleshooting / SRS Maintenance52B-15
Inspection Procedure 2
Communication with MUT-II is not possible.
(Communication is not possible with SRS only.)
Probable cause
If communication is not possible with the SRS only, the cause is probably an open circuit
in the diagnosis output circuit of the SRS or in the power circuit (including earth circuit).

SRS MAINTENANCE
The SRS must be inspected by an authorized dealer 10 years
after the date of vehicle registration.
SRS WARNING LAMP CHECK
Turn the ignition key to the “ON” position. Does the SRS
warning lamp illuminate for about 7 seconds, turn off and
then remain extinguished for at least 5 seconds? If yes, SRS
system is functioning properly. If no, consult page 52B-6.

SRS – SRS Maintenance52B-16
SRS COMPONENT VISUAL CHECK
Turn the ignition key to the LOCK (OFF) position, disconnect
the negative battery cable and tape the terminal.
Caution
Wait at least 60 seconds after disconnecting the battery
cable before doing any further work. (Refer to P.52B-3.)
SRS CONTROL UNIT (SRS-ECU)
1. Check SRS-ECU case and brackets for dents, cracks,
deformation or rust.
Caution
The SRS may not activate if the SRS-ECU is not
installed properly, which could result in serious injury
or death to the vehicle’s driver or front passenger.
2. Check connector for damage, and terminals for
deformation or rust.
Replace SRS-ECU if it fails visual check.
(Refer to P.52B-24.)
AIR BAG MODULES, STEERING WHEEL AND CLOCK
SPRING
