The system for the rear massage function consists of five parts:

• The Rear seat function module (RSX) whose task is to communicate with the rear seat function control panel and to control the electric motor for the rear backrest angle and activate the massage unit.
• Switches for the rear seat functions control panel
• Massage unit
• Massage pump
• The air cushion unit consists of five air cushions.

The system for the rear backrest angle consists of three parts:

• Rear seat function module (RSX).
• Switches for the rear seat functions control panel
• Electric motor

The rear seat functions module (RSX) is mounted in the backrest console near the fans below the refrigerator behind the second row of seats. The massage unit is located in the backrest on the seat. The massage pump is also located in the backrest on the seat. The air cushion unit is attached with air hoses to the massage unit in the seat. The air pump is connected to the massage unit, both with air hoses and wires. The electric motor for the backrest angle is positioned on the outside of the seat.

The Rear seat functions module (RSX) is 30 powered and communicates with the climate control module (CCM) via the LIN-bus. The control module activates the massage unit and powers the electric motor for the rear backrest angle and forwards the LIN communication between the rear seat functions control panel and the climate control module (CCM).

The massage function can be set to three different levels.

The rear seat functions module (RSX) is not diagnosable by the Climate control module (CCM).
