• Electronic alarm system engine hood contacts (S62)
• Storage compartment switches (S85)
• Glove compartment illumination switch (E13/2)

Reading of the following signals: 

• Brake lining wear front left

Scanning the following signals: 

• Circuit 61 (the pre-exciter current is generated in the SAM by a series resistor)

Switching loads via semiconductor switches: 

• Stationary and park lights front right (E1e3)
• Dimmer lights front right (E1e2)
• High beam/headlamp front right (E2e1)
• Fog lamps front right (E1e4)
