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.
Inner tailgate pushbutton and outer tailgate pushbutton
Using the two buttons (inner tailgate pushbutton and outer tailgate pushbutton) it is possible to open the tailgate when the vehicle is unlocked and stationary.
The inner tailgate pushbutton is installed in the center console control panel. The center console control panel outputs the button signal as a request to the IHKA control unit. The IHKA control unit serves as a data interface and outputs the request as a message on the bus connection to the junction box electronics (JBE).
The junction box electronics evaluates the button signals of the two buttons (inner tailgate pushbutton and outer tailgate pushbutton). The junction box electronics activates the opening of the tailgate.
