The CAN-bus terminates in a resistor. It prevents
the transmitted data from returning as an echo
from the ends and corrupting data.
The terminal resistances of the CAN-bus have a
value of 120 and are located in the ABS
control module (w/EDL) -J104- and the Engine
Control Module (ECM) -item 3-. This results in an
overall terminal resistance of approx. 60 . The steering angle sensor -G85- transmits its
data to the control module via the CAN-bus. It
does not have a terminal resistance.
As of implementation of control module 8D0 907
389 D/E, the CAN-bus is connected centrally in
the Engine Control Module (ECM) with a
resistance of approximately 66 . All other
control modules connected to the CAN system
(for example the ABS control module -J104-) are
connected with a high ohm resistance of 2.6 k .
