Wireless Control Stop Function; Door Lock Motor Protective Function; Remote Panic Operation - Toyota Camry 1999 Electrical Troubleshooting Manual

SYSTEM OUTLINE
Door lock control (Lock and unlock) and panic control (Theft alarm and flash) is performed by remote control, without the
ignition key inserted in the door key cylinder, using low–power electrical waves emitted by a transmitter.
1. WIRELESS DOOR LOCK OR UNLOCK NORMAL OPERATION
With the ignition key not inserted into the ignition key cylinder (Unlock warning SW off) and all the doors completely closed,
when the lock or unlock button (Transmitter) is pushed, the wireless door lock ECU receives the electrical waves from the
transmitter, causing it to operate.
As a result, the ECU judges whether the door is locked or unlocked based on the signal from the door lock motor and door
unlock detection SW, and sends a signal to the theft deterrent ECU and integration relay to switch the condition from lock to
unlock or vice versa, causing the door lock motor to operate.
2. VISUAL CONFIRMATION OF LOCK OR UNLOCK
If all doors indicate that they are locked after the lock command, parking lights and taillight will flash once. If any door
indicates that it is open after the unlock command, parking lights and taillights will flash twice.
3. WIRELESS DOOR UNLOCK OPERATION
Pushing the unlock button (Transmitter) once, driver's door is unlocked. Furthermore, pushing the button again within 3
seconds, the other doors are unlocked.
4. AUTOMATIC LOCK OPERATION
With the ignition key not inserted into the ignition key cylinder (Unlock warning SW off) and all the doors completely closed,
after pushing the button (Transmitter) to unlock all the doors, if a door is not opened within 30 seconds, all the doors will be
automatically relocked.

5. WIRELESS CONTROL STOP FUNCTION

If a door is open (Door courtesy SW on), a signal is input from the door courtesy SW to the wireless door lock ECU, stopping
wireless door lock or unlock.
If the ignition key is in the ignition key cylinder (Unlock warning SW on), the unlock warning SW inputs a signal to the
wireless door lock ECU, stopping wireless door lock or unlock.

6. DOOR LOCK MOTOR PROTECTIVE FUNCTION

If the door lock or unlock condition does not change after wireless door lock or unlock operation, 2 seconds later, the
integration relay ECU sends current three times to the door lock motor. If the door lock condition still has not changed as a
result, the wireless door lock ECU stops reception and stops door lock and unlock function.

7. REMOTE PANIC OPERATION

Panic will function when doors are locked or unlocked, open or closed. When the panic button (Transmitter) is pushed once,
theft alarm sounds and headlights and taillight flash. Then, the panic or the unlock button (Transmitter) is pushed once more,
sounding and flashing will stop. Panic will not function when ignition key is in ignition key cylinder.
