Control Module Communication (Faulty Communication)
Control Module Communication (Faulty Communication)
Description
The control modules transmit and receive information via a standardized serial communication method - CAN (Control Area Network). The diagnostic trouble code (DTC) is stored if the engine control module (ECM) registers serious interference (CAN communication blocked). Note! In the event of system communication problems, it is not possible to communicate with the engine control module (ECM). Therefore it will only be possible to read off the diagnostic trouble code (DTC) if the fault is intermittent. Substitute value: The engine control module (ECM) shuts itself off (bus-off). NOTE: The engine control module (ECM) will remain shut off until the power supply is broken (15, 30, x-supply). When the power supply is switched on, the engine control module (ECM) will make a new attempt to communicate.
Cause and Solution
Contact resistance or oxidation in the terminalsOpen-circuit in the control area network (CAN) wiringShort-circuit between the control area network (CAN) wiringInternal fault in the engine control module (ECM)Internal fault in another control module in the same part of the control area network (CAN).
