Had an ice storm this weekend, took the truck out a few times in 4 wheel drive. This evening, I started the truck and the ABS warning light is on, also, the ABS motor still runs, even with the ignition off. I found the fuse in the under hood electric system for the ABS and pulled it.

 

1999 Sierra 1500 ext. cab, new body style.

 

Anyone have any ideas? Is it safe to drive with the ABS not working for a few days?

Haven't you ever owned a vehicle without ABS? That's what you have now and it's just as safe.

 

You need a new EBCM (module). I believe there are places on the Internet where you can buy a reman or you can get yours fixed. You can probably even find some reference to those places here. I'm sure it has been discussed before. Otherwise, it's pretty pricey.

Check modulemaster.com...alot of folks here have had they're EBCM's repaired there with great results dirt cheap (less than $20 I think). A new EBCM will run over $800.

Yes, the company mentioned above has been posted in other threads previously. A search for "abs running" or abs module may give you some other options as well as confirm that this is a common problem on the nbs trucks.

I lived the same problem!  No issues w/ driving w/o the ABS fuse in.. Like said before, just realzie the ABS portion of your brakes do not function...so pump yourself :D

When I pulled out the fuse, the ABS light stayed ON and now the BRAKE LIGHT is ON... any issues with this? Did you experience the same thing?

 

Thanks everyone for all the help!!!!!!! :thumbs:

Yes, SAME thing. Both lights stayed on, and actually...THe brake one MAY have gont off after a day, but I had the same thing. In fact you may notice other things not work when you remove the module. IE my trac control acted as if I had the disable button pushed while I had the unit sent out for repair. Sounds like the EXACT same thing I had... DONT take it to the dealer!!! its an easy repair, slightly tricky to reach the 4 screws, but...4 screws and 2 or 3 wire harness to un plug, and its off!

I know it! The guy wont let ya down..

 

Also...

I once you remove it, be sure to cover up the area, i used duct tape and some plastic bags, and also made sure I had the wire harnesses in a bag to keep moisture out of it all.

 

And when I re-installed it i took a hair dryer to the unit..and heated up the contact areas as to dry out any moisture that may get 'traped' in there. I fugure it could not hurt..just my 2 cents.

Mine kept going off at low speed on dry pavement. The Dealer cleaned the snesor and everything was fine since. P.S when I pulled my fuse both lights stayed on as well.

 

 

 

 

 

This is a different issue, what he is talking about is the pump running regardless of anything else.. Key in car or not, the pump runs.

 

It is a little diode int there that breaks. When I took mine off I could actually hear it rattle in there. And i guess he replaces them with a 'larger' than oem one.

Moderator : This should be a sticky, It sure seems like a common problem and took me forever to find an answer 6 months ago. I was afraid if I diod get in an accident that i would be liable without my abs

I was trying to get a thread going that would be good enough to eventually earn sticky status... please visit this thread and add your issues as well ... Message that hopes to be sticky someday

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
