DESCRIPTION
With power back door: The signal for manual locking/unlocking operation of the driver/passenger side door and the signal for locking/unlocking operation interlocked with the driver side door key cylinder are sent to the back door ECU from the body ECU using the MPX line. In response to these signals, the back door ECU causes the back door lock to be locked/unlocked. The ON signal of the back door opener switch, which is output when the switch is pressed, is directly sent to the back door ECU. In response to this signal, the back door ECU causes the back door lock to be open.
Without power back door: The signal for manual locking/unlocking operation of the driver/passenger side door and the signal for locking/unlocking operation interlocked with the driver side door key cylinder are sent to the body ECU. The ON signal of the back door opener switch, which is output when the switch is pressed, is sent to body ECU.

INSPECTION PROCEDURE
1 CHECK POWER BACK DOOR
2 CHECK DTC
3 PERFORM ACTIVE TEST BY INTELLIGENT TESTER
HINT: During the ACTIVE TEST, the intelligent tester sends a signal to the body ECU to drive all the power door lock motors. If all the power door locks operate, the power door lock motors and the harness between the power door lock motors and body ECU are considered to be functioning normally.
BODY (Multiplex network body ECU)
4 INSPECT BACK DOOR LOCK ASSEMBLY
Then, check operation of the latch.
Standard: The latch turns to the open-latch position
