Ask a Heavy Equipment Repair Mechanic for Answers ASAP
Hello i can help can you give me your engine serial number?
ok current ecm code is AU90061.10 and the latest revision is .30 The only way to fix this fault is to get an ecm software update. from Cummins ,I have listed the fixes below. The reason that you have this fault is The Cummins ECM did not receive a multiplexed message from an OEM VECU within the time limit or did not receive it at all.When the ECM is set up properly (components enabled and OEM VECU source addressed correctly) to receive information from an OEM VECU, but the OEM VECU is actually transmitting a message that says that component is not available for multiplexing. This can be caused when a multiplexed component is enabled in the Cummins ECM, but the OEM VECU source address of the VECU transmitting the component message is incorrect in the CumminsECM, or the OEM VECU is not set up to transmit the multiplexed component message.
