Ultrasonic interior monitoring
On Board Diagnostic (OBD)

General Information

The ultrasonic interior monitoring system is only
offered in conjunction with the anti-theft system.
The security provided by the anti-theft system is
enhanced through addition of the ultrasonic
interior monitoring option.
Interior monitoring activates the anti-theft alarm
when unauthorized attempts are made to enter
the vehicle through the side windows.

Function
The ultrasonic interior monitoring system
consists of:

Control module for ultra-sound sensors -
J347-
Ultra-sound sensor, left for anti-theft warning

The ultra-sound sensors in the right and left
upper B-pillar trims monitor the side windows and
send the monitoring signal to the control module
for ultra-sound sensors.
If the monitoring signal deviates from the norm,
the control module for interior monitoring
activates the alarm via the control module for the
anti-theft system.
In addition to the contact switches in the lock
units, glass break sensors in side windows as
well as the conductor loop in rear window, (only
for Avant), serve for securing the exterior of the
vehicle.
The control module for interior monitoring
activates the warning lamps next to the door
locking buttons. These warning lamps provide
further information regarding the interior
monitoring system.

Repair Manual, Electrical Equipment Interior monitoring can be manually shut off for
the duration of a door closing via the switch for
interior monitoring.

The ultrasonic interior monitoring system is
capable of extensive On Board Diagnostic
(OBD). If malfunctions in component parts
develop, DTCs are stored in the DTC memory of
the control module. Malfunctions can then be
identified using the VAG1551 or VAG1552 scan
tools.

Diagnostic Trouble Code (DTC) table, interior monitoring

Notes:

The following table lists all the DTCs that can be recognized by the control module for interior monitoring and printed out
by the VAG1551 Scan Tool (ST). The DTCs are listed in order according to their 5-digit numbers.
DTC 5-digit numbers appear only on the print-out from the scan tool.
Before replacing a component shown as malfunctioning, check wiring and connections to the component as well as the
Ground (GND) connections according to the relevant wiring diagram.
When a repair has been completed, the system should be armed and then disarmed. Then check and erase DTC memory
using the VAG1551 Scan Tool (ST).
DTC memory records all static and sporadic malfunctions. When a malfunction occurs, it is first identified as a static
malfunction. If it does not occur again it is registered as a sporadic malfunction, and the letters "/SP" appear at the right of
the display.
After system is armed, all existing malfunctions are automatically re-classified as sporadic malfunctions and will only be
registered as static malfunctions if they still occur after testing.
Sporadic malfunctions which no longer occur after 50 driving cycles are erased automatically.
The three digit malfunction type number appearing next to the DTC is a data code which may be disregarded.
