Crash Unlocking

The crash message is transmitted from the Safety Information Module (SIM) via the ZGM to the K-CAN-S. The CAS receives the message and passes it on over the K-CAN-P.

The message is made available to the door modules and the Power Module. A priority "unlocking message" is simultaneously created by the ZV master in the CAS and forwarded to the door modules and the Power Module. This is to ensure that the system is unlocked in each case even if the crash message were to be delayed because of a currently active message. Unlocking of the Central Locking system in the event of a crash is only permitted under the following conditions:

• Terminal R ON
• Terminal 15 ON
• Vehicle is not in double-locked state (for theft protection).
