ABS/Brake light gremlin

Hello again!

 

Now I am on the the ABS/Brake light gremlin now.

 

Symptom:

 

Driving along, not using the brakes. Both ABS and Brake lights come on at the exact same time

 

If you stop, turn of the burb, and crank it back up, the light goes away. It does eventually come back on.

 

I have not seen it come on while I am actually using the brakes.

 

It doesn't matter if I am towing or not.

 

What I have done so far:

 

I cleaned the ground per some suggestions I have seen. that did not help.

 

Next step:

 

Get codes by going by Precision Tune or something like that?

 

Get feedback from you folks and follow through on that?

 

Go ahead and replace the ABS module?

 

Thanks in advance!

 

 

PS. this is the car I race and tow with the Suburban.

I have the same thing going on and plan to just get the codes from a free scan at auto zone.

 

Even with the lights on I have full abs capability so its just a nuisance to see the lights on.

Scan the EBCM And have the code diagnosed and ignore all crap before this post , it's all nonsense I'm afraid and misinformation

 

Do it right once

Don't worry about it, you're only guessing on someone's wallet content without having any experience or diagnostic ability ,,, what's so ever

 

Glad I can help you as well

If you would have read the description you would have noticed it says "You may have code C0265 Electronic Brake Control Module Motor Relay Circuit"....Sooo scanning was is a given (At least to anyone paying attention anyway). Hell they had the truck on a scanner at the very beggining. Also what about this fix cost's anything other than time? This video is about a repair NOT a replacement.

It is fine for people to disagree but everyone needs to show respect for each other. We are a community that strives to help each other out and the first step towards that is respect for each other.

OK people stay calm! All is well.

 

I am going to get it scanned, I promise. I am also not going t take the ABS module apart, as it would render it unexchangeable.

 

Having said that, once the lights come on, they stay on. They are not intermittent. This guy is describing ABS/Brake flashing intermittently. Mine only go off after I shut the burb off and turn it back on.

 

The one thing I did get from the video is that the ABS unit can stop working due to vibration, so scanning the codes to verify the ABS sensors work is the next step, and replacing the module is the step after that.

 

I'll let everyone know what I find.

 

PS. I was looking for other steps to take so I appreciate the suggestions and did watch the video. We are all smart people here, but remember, if someone suggests I jump off a cliff, it doesn't mean I am going to do it!

 

Thanks.

I did the video as I had code 265. It was hard to cut the glue and more of a pain to get to (under seat on frame). I am very experienced in soldering and circuit boards but that was very easy to do and code cleared. They do sell repaired modules for about $150 or repair your for same. P.S. you need a code reader that can read ABS codes.

      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.
