2010 kenworth t660 low coolant warning

[Starlight]

Kenworth has a problem with the ecm not reading coolant level correctly in some chassis. There is not necessarily a wiring problem or a sensor issue. Its only due to the cummins ecm not reading the signals from the oem sensor correctly resulting in a low coolant warning. To repair find out from kw if there is a update avail for your vin. If yes its just a little module that plugs into the existing coolant level sensor plug and eliminates the intermittent coolant level warning. I have seen and done this update a few times. Works like a charm afterwards. Not saying there arent actual wiring issues such as high resistance with your unit though.
