Very good educative video!!!

[@wile80pro93]

Great video How did you get the voltage chart and resistance reading chart?

[@yurytelegin1162]

Thank you very much!! How to find out the voltage parameters for the def heater line#5 ??? Where can I find that manual??

[@yurytelegin1162]

And when you diagnosed it, did you keep the egnition start key on??

[@simonsays6924]

@@yurytelegin1162 it show code on my dash. What code you have? You check with multimeter if no resistance means broken wire like on my truck was. But could be short. So should be resistance. Multimeter will show you. I found manual when googled code.

You can get the full shop, not owner manual for any truck online. Dodge the ads and this site is rock solid for pdf manuals. www.pdfmanual4trucks.com/freightliner/

Is the truck drivable when this happens?

[@stratefacts9075]

I drove a month ...one day on freeway my truck derated then shut off......

[@thereckchanic4709]

The truck will drive and don’t go into derate as long as the ambient temperature does not drop near or below freezing.
