LIFTGATE OPENER SYSTEM

id091400702800


Outline

•  A liftgate opener system has been adopted in which the liftgate can be opened just by pressing the liftgate opener switch.

Function

•  When the liftgate opener switch is pressed, the liftgate latch and lock actuator operates to open the liftgate.
•  The liftgate opener system is controlled based on the following CAN signals:

CAN signal sending module

Signal name
Via instrument cluster from PCM
Vehicle speed signal

Operation

•  When the body control module (BCM) detects the liftgate opener switch on signal while the door lock-link switch (driver's side and passenger's side) unlock signals (driver's and passenger's door locks unlocked) are detected with the following conditions met, it opens the liftgate.

Operation condition

―  Vehicle speed of 3 km/h {2 mph} or less received
―  The door of driver’s side is unlocked


Open operation

1.  When the liftgate opener switch is pressed, it turns on (1).

2.  When the operation condition of the liftgate opener system is met, the body control module (BCM) sends a liftgate release signal (2) by using CAN communication to the electrical supply unit (ESU).

3.  When the electrical supply unit (ESU) receives a liftgate release signal (2), it turns the transistor on (3) and turns on the liftgate release relay.

4.  When the liftgate release relay turns on, the liftgate latch and lock actuator operates (4).
