Hello .. thanks for the donation .. much appreciated

The locking units located in the doors (door lock) have an electric motor. The motor locks the door and also takes care of the "Safe" condition; that is, after locking at an external lock (door lock, tailgate, or radio remote control) the vehicle is protected against theft and can no longer be unlocked from the interior. The feedback on the respective condition in control module occurs via the contact switch in the locking unit.
All the known convenience functions can be performed with the electric convenience system, interior lights control, Anti-Theft Alarm with interior monitoring, electric windows, mirror and the radio remote control. If the Airbag Control Module is triggered, a signal is sent to the convenience control module to unlock the doors.
The Convenience System Control Module (J393) is located under the dash panel and is secured with a bracket to the steering column. It is equipped with a DTC memory. The On Board Diagnostic (OBD) connection is located under the driver's knee bar to left of the steering wheel.

The convenience system includes the following.
Central locking
Anti-theft alarm
Electric windows
Radio wave remote control
Mirror

The control module recognizes DTC's and malfunctions in the central locking convenience system and stores them in a nonvolatile memory. Testers VAG 1551 and 1552 can be used to check the DTC memories and code control modules as well as the function On Board Diagnostic of the VAS 5051. The function "Guided Troubleshooting of the VAS 5051 should be used for troubleshooting in diagnostic cable systems. Using this system a systematic malfunction check s guaranteed, from the fuses via wiring, connections in the current path.
The malfunction information displayed is used to refer to a DTC table with notes on the possible causes for directed repair measure. Malfunctions which can be attributed to a temporary open circuit in the wiring or a loose contact, will also be stored. These malfunctions will be displayed as sporadic DTCs "SP." Only statistical malfunctions are considered:
Central locking inoperative
Mirror positioning motor inoperative
Electric window positioning motor inoperative
CAN-bus communication inoperative.
NOTE:Before changing a component erase DTC memory, perform functional checks and check DTC memory again.

Hope this helps
