       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 .
