Component Tests and General Diagnostics
ON-VEHICLE INSPECTION1. CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS
HINT:
- The switch described in this text is a switch for transmitting signals which is built into the door control transmitter.
- All the functions listed below must be checked in comparison with the remote control operational area.

Check that the power back door reverses right when the back door switch is pressed again while the door is automatically moving (no delay).
6. Check that all the power windows and sliding roof (standard type only) open when the UNLOCK switch has been held down for 2.5 seconds or more and they stop operation when the switch is released (manual operation).
c. Check the chattering prevention function.
1. Check that the corresponding operation occurs only once and is not repeated continuously while the switch is held down. However, when the switch is operated repeatedly at 1 second intervals, check that the corresponding operation is carried out.
d. Check the automatic locking function.

2. 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.
e. Check the switch operation fail-safe function.
1. Check that the doors can not be locked by 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.
f. Check the operation stop function when a door is open or not completely closed.
1. Check that the doors are not locked by the switch while any door is open or not completely closed and the wireless door lock buzzer sounds for 10 seconds.
g. Check the repeat function.
1. 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, which is in the unlocked state, is being restricted.
h. Check the hazard warning lamps flashing and warning buzzer sounding functions (answer-back).
1. When the LOCK switch is pressed, check that the lamps flash once and the buzzer sounds once simultaneously with the locking of all the doors.
2. When the UNLOCK switch is pressed once, check that the lamps flash twice and the buzzer sounds twice simultaneously with the unlocking of the driver side door.
3. When the UNLOCK switch has been pressed again within 3 seconds, check that the lamps flash twice and the buzzer sounds twice simultaneously with the unlocking of all the doors.
4. When the UNLOCK switch is held down for 2.5 seconds or more, check that the buzzer sounds once and all the power windows and sliding roof (standard type only) start opening operation.
5. w/ Power back door: When the power back door switch has been held down for 0.8 seconds or more, check that the buzzer sounds twice simultaneously with the operation of the power back door.
