Could possibly be bad abs sensors, blown abs fuse?

Are you loosing brake fluid? Does your pedal feel mushy? Do you hear a quite "woosh" when you press your brake pedal?

 

Most of the time, I find that this is either due to a bad fuse (as ss502GMC suggested) or a leaking rear brake cylinder.

The last possible cause is a busted vacuum brake booster, but it has to be in particularly bad shape to effect the abs.

The sonoma, and SUVs of the same series have been know to have bad brake modules. Get the codes scanned, these are not DTCs and an ordinary code reader cannot do it. It must be a Tech 2 or the like.

 

The first thing I would check though, would be the abs sensors, wiring, and rings at the wheels. Clean them up if needed. Second as mentioned above, check fluid and replace if necessary.

 

You can always try Module Master if it is time for a module rebuild.

... get your abs wheel speed sensors checked... and visually check the wiring to each... the wiring can get corroded, frayed, etc.... or maybe a sensor itself has an internal problem

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      There's absolutely a mountain of profit in catering to the "I do my own research" crowd, people who are certain they know better. And I don't mean there isn't data to support that 0w40 produces less wear product than 0w20 in an engine like the 3.0 Duramax, that only feeds them the assurance they need. Again, my whole thing with oil selection is, sure, 0w40 or 0w30 produces less wear product. Are we talking the difference between the engine lasting only 100k versus 200k? Or are we talking more like, if the engine will already go 350k on a good 0w20 regimen recommended by the OE, is using 0w40 going to get us to 355k, assuming we can even get the rest of the truck to last that long, meanwhile sacrificing the first 5y, 100k in powertrain warranty. The answer isn't easy, there are tradeoffs.   I willfully use 0w20 Dexos D for this reason, knowing that a 0w40 will produce slightly less wear. I don't believe the delta in wear product is meaningful over the lifetime of the engine, and I place much more importance on driving style and overall feeding and care of the engine as a whole. It's the mentality that someone can abstain from alcohol their whole life which is an amazing boost to health by itself, theoretically. But if they're sedentary, that lifestyle choice will most likely kill them young despite their other, concerted efforts. Maybe someone doesn't drink AND they are the perfect picture of health and activity AND they use 0w40 AND they treat their engine perfectly. If living until 130 years is the goal, sure, do that. But it's going to be a really old truck falling apart around a good engine for that last 30 years, without a doubt.   I watched Demonworks' other video on the 100k+ 3.0 Duramax that had dealer 0w20 changes on what appears to be OLM-prescribed intervals (8-10k).   The QR codes are still present and readable on the main bearings. That's how little wear it has.   That's not proof that anyone else should stick to 0w20, but it's confirmation, for me, that 0w20 is perfectly acceptable to use in these engines.

      1Based on independent testing of OE 0W-20 in the Peugeot TU3M Wear Test as required by the dexos1 Gen 2 specification.

      oh ya that's good to know - I would rather use a gear than the brakes down a long hill.  I would not let cruise control take over on snow or towing a trailer for sure on hills anyway.     The other thing about the CO trip was that was all done above 6K feet for the most part, so that has to use more gas as the motor is down a good amount of power up there.   If I drove my 2016 Camaro with a very similar V8 to this 6.6 it would probably get about 23-24 on the fast run up to NE.  But the premium fuel premium is steep here in CO, so it would still only save about $40 in overall costs for the round-trip.  And you sure can't carry much gear in a convertible camaro!
