I have the same problem (read my own code as well). My codes were intermittent and all over the place, but I believe my root cause to be a loose relay on the ECBM. When the weather cools down I intend to pop it off and take a look inside.

Pretty common on the 800 series. Google search on the subject. Tons of info. Many cases have been broken solder joins in the EBCM. You can have them rebuilt fairly inexpensively and quickly

remove the EBCM, contact Module Masters (google them), send yours to them to get it rebuilt, and get a better one with a 5 year warranty sent to you, if you live in the rust belt, good luck getting the EBCM off, it is no fun..

I had them do my module last year.

 

100% agree that the removal process is no picnic. My job resulted in new brake lines through out the truck due to corrosion.

With mine, I first tried to just remove the ebcm from the valve block without removing it from the truck. I could not get the torx bolts out due to corrosion and the lack of room to get at them with sufficient leverage.

 

Upon attempting to pull the whole assembly, I found that the valve block and the brake line fittings had fused and corroded quite badly. Line wrenches were useless. I ended up cutting the brake lines and using a quality six point socket, liberal amounts of Kroil and a lot of colorful language.

 

You may be in a better place than I am. My truck has spent it's entire life in Michigan and northern Ohio.

Plan on having to remove the whole ABS module to get the screws out, unfortunately...

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
