Initialization and Learning Value Saving

All PTM initialization and learning cannot be performed with the diagnostic tool (GDS). It must be operated manually.
Initialization and learning value saving are procedures to reduce variations in the parts that make up the PTM. In other words, if a new actuator or trunk panel is installed, the liftgate opening angle may differ depending on part variations. When initialization is performed, the liftgate opens and closes repeatedly, and the initial values are set after the liftgate opening angles are recognized. PTM initialization is a method to reduce the difference in opening angle that may occur when parts are replaced. The saved initial values are stored permanently.
  1. To replace the PTM
    1. Install the new PTM in the vehicle, then connect the connector.
    2. Close the liftgate manually
    3. When the external manual switch is used to open the liftgate, initialization is completed with a buzzer sound.
  2. To replace parts that may affect the PTM, except for PTM unit parts.
    1. Press the liftgate interior switch
    2. Press the liftgate exterior manual switches simultaneously.
    3. When pressed for 3 seconds or more, a single buzzer sound is heard.
    4. Close the liftgate manually
    5. When the external manual switch is used to open the liftgate, initialization is completed with a buzzer sound.
    1. Do not stop the liftgate while saving the learning value. Make sure the parameter values can be saved by turning off power and closing based on PTM (Power Trunk Module) control.
    2. The safety function is enabled while the parameter value is being saved.
    3. Once the parameter value is saved, it will not be deleted even if the battery is discharged, and you do not need to repeat the saving process after charging the battery.
    4. If you perform the saving process again after the parameter value has been saved, the new parameter value will be saved in the Power Trunk Module.
