I have a cat 785b that keeps flagging up about four error codes relating to the vims and then a heap relating to temp sensor errors etc.
I have had the local cat dealer look at it several times. I have replaced the vims ecu with a second hand unit and when that one was no good i replaced it with another second hand unit (apparently this one was originally from a 793 but it is the same part number) the dealer flashed the ecu but that did not help. He told me he was having data link problems with the cat ET dropping out.
Anyone got any suggestions.
