Scanning the fuel level sensor (B4) 

The resistance valve of the fuel level sensor (B4) is scanned every 255ms. The resistance value is ordered to a percent value that is averaged with the previous value and stored in the passenger compartment CAN Scanning the following signals:

• Transmission and receiving units in the passenger compartment (A26/14)
• ATA [EDW] inclination sensor (B33)

Switching loads via semiconductor switches: 

• Lighting on the rear outside lights
• Trunk lighting (E18/1)
• Turn signal rear left
• Turn signal rear right

Values : 

• Term. 15
• Term. 50

Switches in the following relays: 

• Relay 1, Terminal 5R (N10/2kQ)
• Relay 2, Terminal 15R (N10/2kM)
• Rear window defroster relay (K40/5kU)

The SAM control unit in the rear (N10/8)  is connected to the passenger compartment CAN for the exchange of data.
