The central control unit for convenience
system, J393, has the usual diagnostic functions,
such as read fault memory, read measured value
blocks, adaptation, coding, as well as selective and
sequential actuator test at its disposal.

The selective actuator test initiated by the diagnosis
tester can be used to check the following actuators:
– Indicator light for safe central locking K133
(in door rim)

–Tilt sensor
– Passenger compartment sensor
– Convenience function via radio
–Right-hand traffic
–Avant detection
–Rear sun blind
Convenience electrics

The door control units have a similar functionality to
those used in the Audi A8 ´03 and are used in the
Audi A6 ’05 with appropriately adapted functions
and actuation features.
The separate installation of the door control unit
and the power windows motor is new here.
Stand-by master function
As in the Audi A8 ´03, the door control unit on the
driver’s side J386 controls central locking if the
central control unit for the convenience system
J393 fails. If there is no co mmunic atio n b etw een the
driver’s-side door control unit J386 and the central
control unit for the convenience system J393, the
other door control units evaluate the information
from the driver’s-side door control unit directly.
In this case, it is no longer possible to open the
vehicle via remote control or Advanced Key.
Diagnosis
The address words 42, 52, 62 and 72 "Door
electronics" offer diagnostic options, such as
measured-block reading, coding or the selective /
sequential actuator test (the selective actuator test
is used for the targeted activation of actuators).
Versi on s
Low-Line and High-Line versions of the door control
units are used.
The High-Line version includes the following
functions, for example:
– Advanced Key
– Memory switch block
– Ambient lighting
–Area lighting
–Folding mirrors
– Automatic anti-dazzle mirror
– Electric child-lock
