Control unit J197
The control unit is the central element of the
system. It is installed in the vehicle in front of
the glove box.
It processes the relevant messages from the
other bus users, and the discreet input sig-
nals (see function diagram and CAN informa-
tion exchange).
The principal result of this processing work
are the signals to actuate the compressor, the
solenoid valves and the shock absorbers.
Because of the differences between the
standard and sporty running gears, the con-
trol unit had to be produced in two versions
(software application).
* These numbers are correct as at 06/2002. Changes may be made as a result of further
technical developments.
(See current Repair Manual.)
