(ATA/Tow-Away Protection/Interior Protection Control Unit, Component Description - GF80.50-P-4131GR)
Model 166
up to Model year 2016
with CODE 882 (Interior monitoring (with ATA [EDW] only))
Shows Model 166.0
Location
The ATA [EDW]/tow-away protection/interior protection control unit is located on the overhead control panel control unit (N70).
Task
The ATA [EDW]/tow-away protection/interior protection control unit has the following tasks:
- Reading in of signals
- Evaluation of input factors
- Actuation of components
- Transmitting signals
- Receiving and transmitting ultrasonic waves
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.
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 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.
Transmitting signals
The signals are transmitted 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 block diagram or function schematic).
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:
- Interior protection receiver (N26/6a1)
- Left interior protection transmitter (N26/6b1)
- Right interior protection transmitter (N26/6b2)
