LIFTGATE OPENER SYSTEM

id091400107300


Outline

•  A liftgate opener system has been adopted in which the liftgate can be opened just by pressing the liftgate opener switch.
•  The rear body control module (RBCM) performs liftgate opener system fail-safe. (See REAR BODY CONTROL MODULE (RBCM).)

Function

•  When the liftgate opener switch is pressed, the liftgate 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
Instrument cluster
Parking brake lever status signal (MTX)
Via instrument cluster from TCM
Selector lever signal (ATX)
Via instrument cluster from PCM
Vehicle speed signal

Operation


Operation condition

When all of the following conditions are met, the liftgate opener system operates.
•  Ignition is switched ON (engine off or on)
―  Selector lever is in P position (ATX)*1
―  Parking brake lever is pulled (MTX)*1
―  Vehicle speed is 3 km/h {2 mph} or less
―  Driver's door is unlocked
•  Ignition is switched OFF (LOCK)
―  Vehicle is stopped (no vehicle speed input)
―  Driver's door is unlocked

*1  :The operation conditions are included depending on the vehicle's period of manufacture.

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 rear body control module (RBCM) turns the transistor on for approx. 0.7 s (2) and turns on the liftgate release relay.

3.  When the liftgate release relay turns on, the liftgate lock actuator operates (3).

4.  When the liftgate lock actuator operates, the latch lever is freed and the liftgate lifts up simultaneously via the spring force of the liftgate weatherstrip and stopper rubber, and opens.
