GF80.50-D-0001H Anti-Theft Alarm System (ATA [EDW]), Function

- with CODE (FZ5) Anti-theft alarm system (ATA [EDW])

The anti-theft alarm system (ATA) is activated via the "Lock" transmit button on the transmitter key or with the "Relocking" function, when all doors in the vehicle are closed.Activation of the ATA system is indicated by the turn signal lamp flashing three times as well as the LED flashing in the interior central locking button (N72/1s7).
The ATA system is deactivated via the "Unlock" transmit button on the transmitter key or by inserting the transmitter key into the EIS control unit (N73), e.g."Circuit 15C ON" is activated.Deactivation of the ATA system is indicated by the turn signal lamp flashing once and when the LED in the interior central locking button goes out.

The ATA system monitors all inputs relevant for the ATA system for their non-actuated state.If a change of status is detected at one of the monitored inputs, an audible and visual alarm is given. The rear SAM control unit (N10) causes the signal horn to output acoustic signals H1.
The rear SAM control unit or the OCP control unit (N70) causes the turn signal lamp and the interior lighting to output visual signals.
The control electronics of the ATA system is integrated into the OCP control unit, which takes over the master function and is interlinked with the controller area network, class B (interior compartment) (CAN B).

The OCP control unit performs a self-test after activation of the ATA.Then the OCP control unit reads in the messages and the status for the following components and "monitors" them:
- EIS control unit via CAN B.
- Rear SAM control unit via CAN B.
- UCP control unit (N72/1) via CAN B.
- Hot water auxiliary heating control unit (N33/3), with code (H12) Auxiliary heater (warm water) or with code (HZ5) 10 kW warm water auxiliary heater with timer via CAN B.
- AAC control and operating unit (S98) via CAN B.
- 2nd warm water auxiliary heater control unit (N33/2), with code (HZ9) Heater booster, diesel or with code (HZ5) 10 kW warm water auxiliary heater with timer via CAN B.
- ATA hood switch (S62) via a discrete line.
- Front passenger door CL rotary tumbler switch (M14/5s1), available from rear SAM control unit via CAN B.
- Driver door CL rotary tumbler switch (M14/6s1), available from rear SAM control unit via CAN B.
- Rear-end door CL rotary tumbler switch (M14/7s1), available from SAM control unit via CAN B.
- Left door CL rotary tumbler switch CREW CAB (M14/8s1), on model 906.2, available from SAM control unit via CAN B.
- Right door CL rotary tumbler switch CREW CAB (M14/9s1), on model 906.2, available from SAM control unit via CAN B.
- Right sliding door CL rotary tumbler switch (M14/27s1), with code (T16) Right load compartment sliding door, available from SAM control unit via CAN B.
- Left sliding door CL rotary tumbler switch (M14/28s1), with code (T19) Left sliding door, available from SAM control unit via CAN B.

Alarm interruption of ATA system
The alarm is interrupted by actuating the "Unlock" transmit button on the transmitter key, simultaneously the ATA system is deactivated which is indicated by the turn signal lamp flashing once and when the LED in the inner central locking button goes out.

The OCP control unit receives the message "Unlock" from the EIS control unit via CAN B.
The OCP control unit transmits the message "EDW_ST (ATA status)" via CAN B to the UCP control unit.
