- Right reading lamp (A67e2)
- Ambient lamp (A67e3)
Alarm system LIN (with code 882 (Interior protection and tow-away protection))
The overhead control panel control unit actuates the alarm siren via the alarm system LIN.
Interior CAN
The signals are sent by the overhead control panel control unit via the interior CAN.
Transmission and reception of ultrasound waves (with code 882 (Interior protection and tow-away protection) or code 852 (Sensor system for anti-theft alarm system (ATA)))
The overhead control panel control unit monitors the vehicle interior for movements by sending and receiving ultrasonic waves. The overhead control panel control unit contains the following components for this purpose:
- Interior protection receiver (N70a1)
- Left interior protection transmitter (N70a2)
- Right interior protection transmitter (N70a3)
Detection of changes to vehicle inclination (with code 882
(Interior protection and tow-away protection) or code 852 (Sensor system for anti-theft alarm system (ATA)))
If the inclination sensor integrated in the overhead control panel control unit senses an alarm-relevant inclination change, an alarm is output.
