Rear-End Electrics

Rear-End Electronics

Rear-End Electronics Control Unit







The rear-end electronics are connected directly to CAN comfort.







Two LIN connections are available to activate a variety of peripheral devices; these connections are divided according to area:
LIN 1 covers = EC interior mirror, sliding roof and roof module with interior surveillance (IS) and inclination sensor (INC).
LIN 2 connects the alarm siren to the control unit.

Rear Exterior Lights

The rear left and right brake lights and the third brake light are controlled by a hard-wired signal from the PSM control unit. The back-up lights are activated by a selector lever CAN signal in PDK transmission.







The tail lights, rear fog lights and license lighting are also connected to the rear-end electronics control unit.

NOTES:
The brake lights are activated in the following cases:
1. Driver brakes manually using the brake pedal
2. ACC brakes automatically
3. Emergency braking is triggered via the electric parking brake.

The emergency brake signal may be triggered at speeds above 43 mph (70 km/h) in the event of sharp deceleration or an ABS intervention.

Interior Lighting

An orientation light is available in the passenger compartment for the center storage compartment. This light is dimmable so that it can be adjusted to the relevant lighting conditions. Safety and exit lighting at the tailgate illuminate the ground around the tailgate and provide better visibility at the rear of the vehicle when the rear hatch is open and it is dark. The luggage compartment lighting illuminates the interior of the luggage compartment when the rear lid is open.







Terminal G1 (comfort lighting, switches off after 16 minutes).

Access and Driving Authorization/Alarm System

The alarm siren is connected via LIN 2 and triggers an alarm if the rear-end electronics detect an attempted theft. The alarm siren is equipment-specific and must be coded in the rear-end electronics.







The roof module is connected via LIN 1. Inclination sensors (INC) and an interior surveillance feature (IS) are integrated in the roof module. If required, these can be deactivated by pressing a button. If the vehicle is locked and an alarm event is detected by the interior surveillance system or the inclination sensors, the roof console sends a signal to the alarm system. A breakage sensor in the rear window detects a broken window and alerts the alarm system.
