Task

The ATA [EDW]/tow-away protection/interior protection control unit has the following tasks:

Reading in of signals
Evaluation of input factors

Reading in of signals

The input factors are read in via the following connections:

Alarm system LIN (LIN B14)
Direct line
Interior CAN (CAN B)

Alarm system LIN

The ATA/tow-away protection/interior protection control unit reads in the signals from the alarm siren (H3/1) via the alarm system LIN.

Transmitting signals

The signals are transmitted by the anti-theft alarm system/emergency call system button group via the interior CAN.

Receiving and transmitting ultrasonic waves

The ATA [EDW]/tow-away protection/interior protection control unit monitors the vehicle interior for movements by sending and receiving ultrasonic waves.

The anti-theft alarm system/emergency call system button group includes the following components:

Location

The ATA [EDW]/tow-away protection/interior protection control unit is located on the overhead control panel control unit (N70).

Actuation of components
Transmitting signals
Receiving and transmitting ultrasonic waves

Direct line

The signals from the following components are read via direct lines:

Left rear window glass breakage sensor (B39)
Right rear window glass breakage sensor (B39/1)
Rear window glass breakage sensor (B39/4)

Interior CAN

The signals are read in by the anti-theft alarm system/emergency call system button group via the interior CAN.

The functions that use these signals are described in the individual function descriptions (see the appropriate block diagram or function schematic).

Evaluation of input factors

The input factors that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.

Actuation of components

The anti-theft alarm system/emergency call system button group actuates the alarm siren via the alarm system LIN.

The functions that use these signals are described in the individual function descriptions (see the appropriate block diagram or function schematic).

Interior protection receiver (N26/6a1)
Left interior protection transmitter (N26/6b1)
Right interior protection transmitter (N26/6b2)
