ATA alarm actuation

Function sequence for triggering alarm

If an alarm criterion is read into the PSE control module (A37), this module sends a CAN message on the passenger compartment bus. This message is received and evaluated by the system acquisition and actuation module (N10/1) and the overhead control panel control module (N70).

The signal-acquisition and actuation module (N10/1) actuates the turn signals via a discrete line. The overhead control panel control module switches on the interior lamps. Simultaneously the ATA horn (siren for ) and rear lamp are actuated by a discrete line.

The version is adapted to the ECE version.

ATA siren

The siren has its own power supply.

When the siren is replaced it must be coded with the HHT (see Diagnosis manual, Body, 13.5)

Tow protection

This is a supplement to the ATA system and serves for sensing changes in the position of the vehicle.

Passenger compartment protection

This is s supplement to the ATA and serves as additional protection for breaking and entry through the side windows.

Retrofitting anti-theft alarm

It is no longer necessary to retrofit the anti-theft alarm, because the insurance requirements applicable in and are fulfilled by the drive authorization system stage 3.
