6. FORCED DOOR LOCK CONTROL
While detecting intrusion into the vehicle and sounding alarm,
alarm control outputs the door lock at the moment the door is
unlocked, and prevents intrusion into the vehicle.
(1) Condition for Starting Forced Door Lock
Detecting any of the following conditions activates
the forced door lock.
Alarm system is in alarm status in active
mode.
Except for the case that the key unlock/lug-
gage unlock switch is turned on.
No key is in the ignition key cylinder.
Some of the doors are unlocked.
Since the start of the last forced lock, 0.38
sec. or more has been elapsed.
(2) Conditions for Stopping Forced Door Lock
Detecting any of the following conditions stops the
forced door lock.
All doors are locked.
An alarm is stopped.
A key is inserted into the key cylinder.
7. PANIC CONTROL
The function to sound the alarm when the user presses the pan-
ic switch of the wireless key.
8. ALARM MEMORY CONTROL
If an alarm is activated while a user leaves the vehicle, when the
user comes back to the vehicle and reset the security system,
the tail lights will come on for 2 sec. to show the alarm occur-
rence.
9. DTC CHECK (Using hand-held tester)
(a) Inspect the DLC3.
The vehicle's ECM uses ISO 9141-2 for communication.
The terminal arrangement of DLC3 complies with
SAEJ1962 and matches the ISO 9141-2 format.
HINT:
If the display shows ºUNABLE TO CONNECT TO VEHICLEº
when the cable of hand-held tester is connected to DLC3, the
ignition switch is turned ON and the scan tool is operated, there
is a problem either on the vehicle side or the tool side.
If communication is normal when the tool is connected to
another vehicle, inspect DLC3 on the original vehicle.
If communication does not function when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool's instruction manual.
(b) Make sure the details of the DLC3.

(d) Connect the hand-held to DLC3.
(e) Turn the ignition switch ON and the hand-held tester
main switch ON.
(f) Use the hand-held tester to check the DTCs, note them
down. (For opening instructions, see the hand-held tes-
ter 's intrusion book).
10. DATA LIST
HINT:
By the DATA LIST displayed on the Hand-held tester, you can read the value of the switch, sensor, actuator
and so on without removing any parts. Reading the DATA LIST as a first step of troubleshooting is one of
the method to shorten the labor time.
(a) Turn the ignition switch OFF.
(b) Connect the hand-held tester to DLC3.
(c) Turn the ignition switch ON.
(d) According to the display on the tester, read the ºDATA LISTº.

PRE-CHECK
1. CHARACTERS OF WIRELESS DOOR LOCK
(a) The operation distance changes according to how cus-
tomers hold the transmitter or where it is used.
(b) Because of using the very weak radio wave, if there is a
strong wave or noise on the frequency being used, the op-
eration distance may become shorter.
2. WIRELESS DOOR LOCK BASIC FUNCTION
(a) Stand on the driver's side. Stay 1 m away from the ve-
hicle.
(b) Turn the transmitter toward the vehicle and press any one
of the transmission switched for 1 sec.
3. INSPECT WIRELESS DOOR LOCK DIAGNOSIS MODE

NOTICE:
When the shrews are tightened loosely, it might cause
faulty contact of battery (lithium battery) and terminals.
(h) Assemble the transmitter to the key plate and the cover.
(i) Using a screwdriver, tighten the screw.
7. REPLACE DOOR CONTROL RECEIVER AND TRANS-
MITTER
NOTICE:
When replacing the theft deterrent ECU or transmitter, reg-
istration of recognition code is necessary because they
are provided as a single components.
(a) Select the operation mode to perform from the following
operation modes.
Add mode
Rewrite mode
Prohibition mode
Confirmation mode
HINT:
The ºAdd modeº is for adding the newly recognized codes
for registration while the already registered codes are re-
tained. This mode is used when the transmitter is added.
When the number of the registered codes exceeds 4
codes, the previously registered codes will be erased in
order, staring from the first registered code.
The ºRewrite modeº is for erasing all the registered codes
and registering newly recognized codes only. This mode
is used when the transmitter or the door control receiver
is replaced.
The ºProhibition modeº is for erasing all the registered
codes to prohibit the wireless door lock operation. This
mode is used when the transmitter is lost.
The ºConfirmation modeº is for confirming the number of
recognition codes that are registered. This mode is used
to check the number of registered codes when new codes
are added to the registration, etc.
(b) Follow the chart on the following page to register the
transmitter recognition code to the theft deterrent ECU.
HINT:
When procedure is out of the specified, the registration
operation is cancelled
