Re: Glow plug error code p 380 Reply #1 – August 10, 2017, 09:53:13 pm Yahoo Message Number: 16156Check your 10A glow plug fuse. It's my understanding that the ecm will not throw a P380 code for a bad plug.. Only for wiring and/or glow plug controller. Good luck, Chris Quote Selected

Re: Glow plug error code p 380 Reply #3 – August 11, 2017, 04:31:11 am Yahoo Message Number: 16158Hi Joe, I have attached 3 files, a schematic and a system description. I'm not sure where the 10A fuse is on your truck. There should also be a 175A mega fuse between the battery and the glow plug relay. It is my understanding that there are some differences between California CARB models and non. I do know that the glow plug relay is a regular problem on these trucks. It is located on the driver's side, behind the engine near the firewall. You should be able to find a replacement for $60-$100. There are quite a few YouTube videos regarding glow plug relay replacement. It is not a hard job. Remember, once you replace fuses and/or the relay you still need to clear the code. Good luck and let me know if you would like some links to YouTube videos.. A video is a much better explanation than what I can provide. Let us know what you find.Chris Quote Selected

Info should be very similar if not identical. My apologies.ChrisOn Aug 11, 2017 1:31 AM, "Chris Mize" chrismize@...> wrote: Quote Selected
Re: Glow plug error code p 380 Reply #5 – August 11, 2017, 05:22:29 am Yahoo Message Number: 16160Here is a link to electrical drawings for our C5500 MDT chassis motorhomes.http://www.dieselplace.com/forum/76-speciality-forums/34-medium-duty-trucks/423764-2007-2009-gm-medium-duty-electrical-manuals.htmlYou will fuse information on page 2 of the link above.Fuses are located in 2 places. Under hood on passenger side near firewall and under dash on passenger side. You have to remove 2 bolts (10mm wrench) to get access to the fuses, circuit breakers and relays under dash. There should be a area in your Kodiak Owner's manual that show where fuses are at. There are also labels on fuse panel covers.I did a lookup for the Code P0380 on Diesel Place. Lots of pickup problems but nothing on MDT. Here is a link.Lots of instructions on how to test.http://www.dieselplace.com/forum/gtsearch.php?q=p0380Make sure you are looking at LLY/LMM not LB7 instructions.BestRon Hall Quote Selected
