Massage Function in Rear-compartment Comfort Seat: Notes
The optional rear-compartment massage gives the rear-seat passenger even more comfort than in the E65. The rear-compartment massage function is being offered in the F01/F02 for the first time at BMW.
An electropneumatic system is used to implement the massage function.
The massage function is available for both the left and right rear passenger seat and can be activated from terminal 30B ON. The seat module is integrated into the back of the backrest in the left rear and the right rear seat and has sole responsibility for the massage function.
The buttons for the massage function are connected via the LIN bus to the junction box electronics.

The junction box electronics evaluate the status of the massage button and sends the status via the K-CAN2.
The central gateway module transfers the signal to the K-CAN. This allows the seat module to receive the current status of the buttons. The seat module evaluates the status, activates the massage function, and monitors it.
In the backrest of the comfort seat, there is a massage pad for the massage function. Pressing the button starts the massage function at the maximum massage intensity. Pressing the button again switches it to a lower massage intensity level.
Pressing the button once again switches the massage function off.
If the button is pressed for longer than 1.2 seconds during the massage function, the massage function will be switched off.
In order to indicate that the massage function has been activated, the seat module sends the request to switch on the LEDs in the button.
The signal terminal 58g ON is made available through the footwell module. The junction box electronics pass on terminal 58g ON to the button. The button then switches the back lighting on.
