Toyota Corolla Repair Manual: On–vehicle inspection
1. Inspect wireless door lock control functions
Hint
:
- the switch described in this text is a switch for transmitting
signals (lock switch, unlock switch
and panic switch) which is built into the door control transmitter.
- All the functions listed below must be checked in the remote control
operational area.
- put the vehicle under the conditions that allow the wireless
control function to be operated (see precaution
on page 73–7).
- check the basic function.
- Check that all the doors lock when the lock switch is pressed.
- Check that only the driver side door unlocks when the unlock
switch is pressed once and the
other doors unlock when the unlock switch is pressed again within 3 seconds.
- check the chattering prevention function.
- Check that the corresponding operation occurs only once and is not
repeated continuously while
the switch is held. However, when the switch is operated repeatedly at 1
second intervals, check
that the corresponding operation is carried out.
- check the automatic lock function.
- Check that all the doors lock automatically as long as none of
them have been opened or all the
doors have not been locked within approx. 30 Seconds after they are unlocked
by pressing the
unlock switch.
- Check that the automatic locking function does not operate when
any door has been opened or
all of them have been locked within approx. 30 Seconds after they are
unlocked by pressing the
unlock switch.
- check the switch operation fail–safe function.
- Check that the doors can not be locked using the switch while the
key is in the ignition key cylinder.
However, this does not apply when the system is in the recognition code
registration mode.
- check the operation stop function when a door is open or not
completely closed.
- Check that the doors are not locked by the switch while any door
is open or not completely closed.
However, the glass hatch open operation is possible in this situation.
- check the repeat function.
- Check that all the doors attempt to automatically lock once again
1 second after the lock switch
has been pressed while the movement of the driver side door control knob is
being restricted
while in the unlocked position.
- check the hazard warning lamps flashing functions (answer–back).
- When the lock switch is pressed, check that the lamps flash once
with the locking of all the
doors.
- When the unlock switch is pressed once, check that the lamps flash
twice with the unlocking
of the driver side door.
- When the unlock switch is pressed again within 3 seconds, check
that the lamps flash twice
with the unlocking of all the doors.
- check the remote panic alarm function.
- Check that the horn sounds, and the headlamps, the taillamps and
the hazard warning lamps
flash for 60 seconds by the theft alarm function when the panic switch is
pressed. Also, check
that the horn stops sounding and the lamps stop flashing when either switch
of the transmitter
is pressed once again.
- check the illuminated entry function.
- When all the doors are locked, pressing the unlock switch causes
the room lamp (when the
lamp switch is in the door position) to illuminate simultaneously with the
unlock operation.
- Check that the room lamp goes off in approx. 15 Seconds if doors
have not been opened.

of the door control receiver connector and the body
ground, as shown in the illustration and table.
