2018 2500 HD duramax. ~15000 m Got the batteries replaced just before trying to get a smog test. Smog test failed as the computer history was cleared and various sensors have not cleared. I've driven about 500 miles and went to retest today but it shows the PM Filter Not Completed. Does anyone know what I have to do to get that to complete? I suspect there may be a longer trip requirement or something. My longest trip has been about 35 miles since changing the batteries. Appreciate any help. Cheers! Sent from my SM-G950U using Tapatalk
the only aftermarket accessories installed are a ham radio (rarely used) and a LED light bar which I disconnected when sorting through this.. The batteries received a Full charge just before taking the truck to the dealer for inspection and they failed their test.. I'm guessing just bad batteries.
Just an update.. the majority of the errors cleared the next day. Last night, the battery failed again and I had to jump the truck. Took it to the dealer today and just got word that the batteries failed the GM test so they will be replacing under warranty. Sent from my SM-G950U using Tapatalk
I've been getting the service trailer brake message for a couple weeks. I haven't towed a trailer in a year. This week I did have batteries too low to start the truck. I threw a charger on it on and all has been good since Wednesday until I got all these messages tonight. I thought the battery drained because I left some lights on a couple times and I really dont drive all that far/long to get them charged up while driving. Is there some way to reset the system? In the event it was just the low/dead batteries that caused this? Sent from my SM-G950U using Tapatalk
2018 2500 HD duramax. ~15000 mi. Started getting a bunch of error messages. Clearly I need to get to the dealer. Does anyone have an idea what may be going on? Brake light is on. ABS light is on Traction control is off DIC - Service Trailer Brake System DIC - Service Power Steering Drive With Care DIC - Service Stabilitrack DIC - Information Park Assist Off (I didn't turn it off) Here are some pics of the errors. Note, one pic was taken before I filled the fuel tank. Sent from my SM-G950U using Tapatalk
It would have fit but I felt that it blocked too much of the light. No use buying a light and putting something in front of it.. It's not big enough that I am overly eager to fill it.. I did retain a piece of the grill that I removed that I may fill the gap with.. I would use the threaded mount at the end of the fixture to mount the extension/filler.
It comes with a full wiring harness and rocker switch. I have not routed and mounted it yet. It's currently just strung into the cap through the window. I'll route it through the grommet in the firewall and find a place to mount the switch next weekend. Here is the light I got. https://www.roughcountry.com/40-inch-curved-led-light-bar-72940blkdrl.html Sent from my SM-G950U using Tapatalk
Well, my brackets look like shit and I'm a shitty welder bit it is strong and rigid. The grill can be removed without removing the light bar. It's rough wired and I'll run it for a couple weeks to see if it needs any adjustment. It was a pain in the ass working alone and trying to fab in that tight space with the grill on.
