Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
The Initialization And Learning Value Saving
The initialization and learning value saving are the works to reduce the variations of the parts comprising PTM. In other words, if a new drive unit or trunk panel is installed, the trunk opening angle may be different depending on the part variations If the initialization is done, trunk opening and closing are repeated and the initial values are set after recognizing the trunk opening angles.
The PTM initialization is a method to reduce the trunk opening angle difference which could occur when replacing the parts. The saved initial values are memorized permanently.
- To replace the PTM unit
- Install a new PTM unit in the car and then connector
- Close the trunk manually
- When using the outside hand switch to open the trunk, the initialization is completed with a buzzer sound.
- To replace parts that can affect PTM, except the PTM unit parts
- Press the trunk inner switch
- Press the trunk outside hand switches at the same time
- When pressing 3 seconds of more, a buzzer sound is issued one time.
- Close the trunk manually
- When using the outside hand switch to open the trunk, the initialization is completed with a buzzer sound.
NOTE:- You should not stop the trunk when saving the parameter values. Ensure that the parameter values can be saved by power opening and closing based on PTM (Power Trunk Module) control.
- The safety function is on while the parameter value is being saved.
- Once the parameter value is saved, the value will not be deleted even though the battery is discharged and you will not have to do the saving process again after charging the battery.
- If you do the saving process again after saving a parameter value, a new parameter value is saved in the power trunk module.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- β’ You smell fuel, burning insulation, or see smoke.
- β’ Brakes feel soft, pull hard to one side, or make grinding noises.
- β’ The engine overheats, stalls repeatedly, or misfires under load.
- β’ You are missing required tools, torque specs, or safe lifting equipment.
- β’ You are not confident in the next step or safety outcome.
