Transmitter Test
NOTE:. lf the doors unlockorlockwiththetransmitter, but
the LED on the transmitter does not come on, the LED
is faulty. Replace the transmitter,. lf anydoor isopen, you cannotlockthedoorwiththe
transmrtter.. lf you unlocked the doors with the transmitter, but do
not open any of the doors within 30 seconds, the
doors relock automatically.. The doors do not lock or unlock with the transmitter if
the ignition key is inserted in the ignition switch.
1. Press the lock or unlock button five or six times to
reset the transmitter.
. lf the locks work, the transmitter is OK.. lf the locks don't work, go to step 2.
2. Open the transmitter and check for water damage.
. lf you find any water damage, replace the
transmrtter.. lf there is no waterdamage, go to step 3.
3. Replace the transmitter battery (A) with a new one,
and try to lock and unlock the doors with the
transmitter by pressing the lock or unlock button
five or six times.
. lf the doors lock and unlock, the transmifter is OK.. lf the doors don't lock and unlock, go to step 4.
Reprogram the transmitter, then try to lock and
unlock the doors.
. lf thedoors lockand unlock.thetransmitter is OK.. lf the doors don'tlockand unlock, replacethe

Transmitter Programming
Storing transmitter codes:
The codes of up to three transmitters can be stored in
the keyless receiver unit memory. (lf a fourth code is
stored. the code which was input first will be erased.)
NOTE: lt is important to maintain the time limits
between the steps. Make sure the doors and the hatch
are closed.
1. Turn the ignition switch ON (lli.
2. Within 1 to 4 sec., push the transmitter lock or
unlock button with the transmitter aimed at the
receiver in the multiplex control unit behind the
driver's side of the dash.
3. Within 1 to 4 sec., turn the ignition switch OFF.
4. Within 1 to 4 sec., turn the ignition switch ON (ll).
5. Within 'l to 4 sec., push the transmitter lock or
unlock button with the transmitter aimed at the
receiver in the multiplex control unit behind the
driver's side of the dash.
6. Within 1 to 4 sec., turn the ignition switch OFF.
7. Within 4 sec., turn the ignition switch ON (ll).
8. Within 1 to 4 sec., push the transmitter lock or
unlock button with the transmifter aimed at the
receiver in the mupltiplex control unit behind the
driver's side of the dash.
9. Within 1 to 4 sec., turn the ignition switch OFF,
'10. Within 4 sec., turn the ignition switch ON (ll).
11. Within 1 to 4 sec., push the transmitter lock or
unlock button with the transmitter aimed at the
receiver in the multiplex control unit behind the
driver's side of the dash.
12. Confirm you can hearthe sound ofthe door lock
actuators. Within 1 to 4 sec., push the transmitter
lock or unlock button again,
13, Within 10 sec., aim the transmitters (up to two
additional ones) whose codes you want to store at
the receiver, and press the transmitter lock or
unlock buttons.
Confirm that you can hear the sound of the door
lock actuators after each transmitter code is stored.
14. Turn the ignition switch OFF, and pull out the key.
'15. Confirm proper operation ofthe transmitter.

System Description
The vehicle is equipped with an immobilizer system that will disable the vehicle unless the proper ignition key is used.This system consists of a transponder located in the ignition key, an immobilizer control unit-receiver, an indicatorlight, and the ECM.
When the key is inserted in the ignition switch and turned to the ON {ll) position, the immobilizer control unit-receiversends power to the transponder in the ignition key. The transponder then sends a coded signal back to the immobilizer
control unit-receiver which then sends a coded signal to the ECI\4.
iEl'JUiliii'tlun"oona"|.r KEYCYLTNDER
lf the proper key has been used, the immobilizer indicator light will come on for about 2 seconds, then go off.lf the wrong key has been used or the code was not received or recognized by the unit, the indicator light will comeon for about 2 seconds, then it will blink until the ignition switch is turned OFF.lf the ignition switch is turned OFF, the indicator will blink for about 5 seconds to signal that the unit has reset
correctly, then the indicator will go off.
lf the customer has lost his key, and cannot start the engine, contact Honda Customer Relations.
