and then goes into normal mode from low power consumption mode.
• Each unit starts transmissions with CAN communication by receiving sleep wake up signals. Each unit trans- mits wake up signals to BCM with CAN communication to convey the start of CAN communication.

DOOR LOCK FUNCTION
DOOR REQUEST SWITCH
DOOR REQUEST SWITCH : System DiagramINFOID:0000000005146875
DOOR REQUEST SWITCH : System DescriptionINFOID:0000000005146876
Only when pressing the request switch, it is possible
to lock and unlock the door by carrying the Intelligent
Key.
• The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function) by carrying the Intelligent Key, which operates based on the results of electronic ID verifica-
tion using two-way communications between the Intelligent Key and the vehicle (BCM).
CAUTION:
The driver should always carry the Intelligent Key
• If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer
goes off to inform the driver (Warning chime function).
• When a door lock is locked or unlocked with request switch or remote controller button operation, the hazard
lamps flash and the Intelligent Key warning buzzer or horn sounds (Hazard and buzzer/horn reminder func-
tion).
• The settings for each function can be changed with the CONSULT-III.
• If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be
registered.
• It is possible to perform a diagnosis on the system and register an Intelligent Key with the CONSULT-III.
OPERATION DESCRIPTION/DOOR LOCK/UNLOCK
• When the BCM detects that each door request switch is pressed, it starts the outside key antenna and inside
key antenna corresponding to the pressed door request swit ch and transmits the request signal to the Intelli-
gent Key. And then, check that t he Intelligent Key is near the door.
• If the Intelligent Key is within the outside key ant enna detection area, it receives the request signal and
transmits the key ID signal to the BCM via remote keyless entry receiver.
• BCM receives the key ID signal and compares it with the registered key ID.
• BCM sends the door lock/unlock signal and sounds Intelli gent Key buzzer warning (lock: 2 times, unlock: 1
time) at the same time as a reminder.
OPERATION CONDITION
If the following conditions are not satisfied, door lock/unlock operation is not performed even if the request
switch is operated.
Door switch Transmits door open/close condition to BCM.
Passenger select unlock relay Enables or disables the unlocking of rear doors when this Intelligent Key option is selected. Item

AUTOMATIC BACK DOOR SELF-DIAGNOSIS PROCEDURE
Self-Diagnosis ProcedureINFOID:0000000005146997
INPUT SIGNAL CHECK MODE
Input signal check mode allows testing of swit ch input signal to the back door control unit.
To activate input signal check mode on the automatic sliding door, perform the following steps:
1. Turn ignition switch OFF.
2. Turn back door close switch to CANCEL (system cancelled).
3. Place A/T selector lever in P position.
4. Using the inside emergency release lever, open the back door.
5. Have an assistant press and hold the back door handle switch.
6. While the assistant continues to hold the back door handle switch, turn ignition switch ON (DO NOT start
engine).
7. After approximately 5 seconds, the back door warning chime will sound for 0.5 seconds.
8. Release the back door handle switch.
9. Within 8 seconds of the back door warning chime sounding, press and hold the power liftgate switch.
10. After approximately 5 seconds, the back door warning chime will sound for 1 second.
11. Release the power liftgate switch.
12. The input signal check mode is now initialized.
The input signal check mode can test the following inputs. The back door warning chime will sound for approx-
imately 0.5 second each time a switch signal input oc curs. Use this test when one of these inputs is not
responding during normal automatic back door operation.
*Back door warning chime should sound as soon as vehicle moves.
Turn ignition switch OFF to end input signal check mode.
OPERATING CHECK MODE
Operating check mode allows self-diagnos is of the automatic back door system.
To activate operating check mode on the automatic back door, perform the following steps:
1. Turn ignition switch OFF.
2. Turn back door close switch to CANCEL (system cancelled).
3. Place A/T selector lever in P position.
4. Using the inside emergency release lever, open the back door.
5. Have an assistant press and hold the back door handle switch.
6. While the assistant continues to hold the back door handle switch, turn ignition switch ON (DO NOT start engine).
7. After approximately 5 seconds, the back door warning chime will sound for 0.5 second.
8. Release the back door handle switch.
