contents are cancelled upon disconnection.
 Reassemble parts in the reverse order of
disassembly procedure unless otherwise
indicated.
 Adjust parts to specifications contained in
this manual if so designated.
Connect the connectors and hoses securely
during reassembly.
After reassembly, ensure all functional parts
operate smoothly.
Airbag system wiring harness is routed near

NOTE:
To prevent static electricity damage to transmitter
printed circuit board, touch the steel area of building
with hand to discharge the static electricity carried
on body or clothes before disassembling transmitter.
B: INSTALLATION
1. TRANSMITTER BATTERY
Install in the reverse order of removal.
C: INSPECTION
1. TRANSMITTER BATTERY
Measure the voltage between battery (+) terminal
and (–) terminal.
NOTE:
 Battery discharge occurs during measurement.
Complete the measurement within 5 seconds.
 During battery voltage measurement, voltage
falls more than 1.8 volts in 3 seconds period.If NG, replace the battery. (Use CR1620 or equiva-
lent.)
D: REPLACEMENT
1. TRANSMITTER REGISTRATION
NOTE:
 A maximum of three transmitters can be regis-
tered for each individual vehicle.
 When replacing the transmitter (key), registration
to immobilizer system is also necessary.
1) Remove the side sill cover at driver’s side, then
connect the registration connectors at front pillar
lower section.
2) Unlock the door lock.
3) Press any button of the transmitter twice while
pressing driver’s door lock switch to unlock side to
be registered.
4) The door lock will automatically lock and unlock
in sequence. This indicates the completion of trans-
mitter registration for first transmitter.
5) If the registration of second and third transmitter
is now to be carried out, repeat the procedure 3)
and 4).
6) Disconnect the registration connectors after the
completion of all registration operations. After con-
firming the operation of door lock using newly reg-
istered transmitter(s), reinstall the side sill cover at
driver’s side.
