Information Bus: Description and Operation
CAN-Bus For ESP
CAN-Bus for ESP
The ESP function relies on an exchange of signals between ABS control module (w/EDL) -J104- (-item 2- in the illustration), the engine control
module (-item 3-) the transmission control module (-item 4-) and the steering angle sensor -G85- (-item 1-).
The matching resistors at the ends of the CAN-Bus are rated at 120 9, and are located in the ABS control module (w/EDL) -J104- (-item 2-) and in the
engine control module (-item 3-).
As of implementation of control modules 8DO 907 389 D/E, the CAN-Bus is terminated centrally in the ECM with a resistance of approx. 66 ohms.
All other control modules in the CAN connection, e.g. -J104-, are terminated with a high-resistance of 2.6 k Ohms.
