The central electronic module (4/56) is the main control module for alarm functionality. The central electronic module determines how the alarm should be activated, deactivated or deployed by receiving information on the Controller Area Network (CAN) from other control modules and via the directly connected signal cables from the components.
Signal cables are directly connected to the central electronic module from:
- Switch in the lock units in all doors (3/74-77), open/closed
- Switch in the lock units in the rear side doors (3/76-77), locked / unlocked
- Switch hood (3/62), open/closed
The central electronic module is controlled via a direct cable:
- All turn signal lamps.
