standardized test procedure: press the transmitter switch for 1 second,
directing the beam to driver
side door outside handle from a distance of 1 m (39.4 In.). The transmitter
should be pointed directly
at the door handle, i.E at 90 angle to the vehicle body.


4 Confirm room lamp on
- Check that the wireless door lock buzzer sounds.

5 Switch to self–diagnostic mode
- Switch to self–diagnostic mode by operating the ignition key cylinder.
- Put the vehicle under the vehicle’s initial condition , insert the key into the ignition
key cylinder and remove it.
- Within 5 seconds after the key is removed (step 1), insert the key into
the ignition key cylinder
(ignition key off) and perform the following once: turn the ignition switch
to on and return it
to off.

if operation has failed, the system will return to normal mode.
Hint
:
- turning the ignition switch on after step 3 has been completed will
end self–diagnostic mode.
- Do not lock or unlock doors during self–diagnostic mode.

- Check that the system has switched to self–diagnostic
mode by the blinking frequency of the room lamp.


6 Check by self–diagnostic mode
- Inspect the diagnosis outputs when the door control transmitter switch
is held down (the diagnosis
outputs can be checked with the outputs of the room lamp).
Hint
:
- in the case of a reception of the normal wave of the door lock and
unlock switch (room lamp blinking),
go to step a.
- In the case of an unmatching recognition code (room lamp on), go to
step b.
- In the case of no diagnosis outputs (room lamp off), go to step c.



7 Register recognition code
- Check that the system can switch to rewrite mode or add mode and whether
a recognition code can
be registered.
