I have an error code in my Durmamax Diesel po380. The engine light comes and goes the truck does not seem to be running any differently. A friend of mine has a scan tool and he plugged it in and got the po380 code which says Glow Plug Heater Circuit A. Any suggestions or recommendations? Please drop me a note. Thanks

Probably a glow plug or relay

I just had the same code in my 04 CA model. It was a #5 glow plug open. Lot's of information on this site telling you how to check them. If yours isn't a CA model it may be a relay. Again lots of information on this site just do a search for the P0380. Good Luck
