Power Liftgate Opening Process

WARNING: This page is about a different car, the 2017 Hyundai Tucson. However, it is still accessible from the selected car via links, so may be relevant.
  1. Opening will start after signals from crash pad lower switch, liftgate handle switch, or wireless remote key (FOB) are received.
  2. The latch motor will unlatch the liftgate by releasing the striker (via the SJB).
  3. To open the liftgate, the PLGM will activate the liftgate spindle motors.
  4. The speed of the spindle motors is monitored via a hall sensor in the motor.
  5. Opening angle of the liftgate will be calculated from the number of pulses of the hall sensor.
    CAUTION: When the motor's movement is restricted PLGM will sense it as an obstacle and either reverse in opposite direction or halt the motor movement.
