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.
