Component Tests and General Diagnostics
Function
The engine control module communicates with all control modules capable of data bus via a CAN data bus.
Data bus-compatible control modules are connected together via two data bus wires twisted together (CAN high and CAN low) and exchange
information (messages). Information not available in the data bus will be recognized as a malfunction by the engine control module as well as other CAN
data bus control modules.
The data bus requires a matching resistor to function fault-free. This central matching resistor is located in the engine control module.
Diagnosis via the CAN-bus wire is undertaken via the diagnostic interface for data bus -J533- in the "Gateway".
NOTE: Read out which control modules are actively connected via data bus to the engine control module in measured value blocks 125 and 126.

See Self Study Program "The CAN data bus".
