What is the solution for the automatic opening of the X3 trunk?
1 Answers
First, confirm whether there is a car key inside the vehicle. When BMW detects the key inside the car and the key used to lock the doors, the trunk cannot be closed. More relevant information is as follows: 1. The trunk door is divided into upper and lower parts. Sometimes, if the lower part is not properly closed, it may automatically open. The trunk lid can be opened via the operation button inside the cabin, the external button on the trunk lid, or the remote control. It can be closed via the external button on the trunk lid, the internal button, or the remote control. The trunk lid module is connected to the internal button on the trunk lid. The trunk lid interlock is controlled by the power supply module (PM), with information received and transmitted via the K-CAN data bus. 2. The external button on the trunk lid is directly read by the power supply module and then transmitted to the trunk lid module. The internal button of the trunk lid is read by the Comfort Access and Start System and transmitted to the trunk lid module. When opening the trunk lid, the trunk lid lock is first unlocked by the unlocking drive. If the power supply module detects that the lock is open (the trunk lid contact is grounded) via the trunk lid contact, the automatic closing drive is activated.
