2019 Silverado LD with 81,000 miles. First change of brake pads. I know I should have done rotors too, but I am away from home on work and only had limited tools and a Sunday to mess with it. So I pad slapped the front, and put it back together. Didn't un-plug any sensors, just pads. After I put the wheels back on I started the truck and was greeted by a host of service errors. When I turn the key forward before the truck is even running the service Stabilitrak message comes up, after I dismiss that Service Trailer Brake comes up. To go along with that the ABS and Traction control lights are on now as well. 

 

I tried scanning it, but the scanner didn't come back with any codes. I tried disconnecting the battery for 5 minutes, but that didn't do anything. The brake fluid is full, between Min/Max. The truck has a great brake pedal now, and drives as it did before. I've put 70-80 miles on it since I did the brake pads yesterday. Any thoughts or input is appreciated. Thanks in advance.

When you say "LD" do you have the OLD body truck that looks like a 2018?  Or is it a NEW body 2019?  

 

Either way, the first place to start is with a good code reader that can read all the modules in the truck and see what codes are set.

Yes it is a 2019 that has the old style like a 2018. I believe the LD stands for Light Duty. It's void of a couple features so I'm told, but I've never wanted for anything. 

 

The two scanners I tried came up with nothing. I'd hate to take it to the dealer to solve this. I have a warranty up to 100k through GM, but something tells me this will be an out of pocket expense.

Both of these I linked above can read codes in every module on GMs.  Many handhelds will give you powertrain and sometimes ABS, these can read codes for BCM, TCM, HMI, Trailer Brake module, etc.

Turns out the Blue Driver won't read the ABS data. That's per Blue Driver.

Ordered the OBD Link MX+, should arrive tomorrow. I've put 700 miles on the truck this week, and it drives normal. Except for the fact that is clearly does not have ABS. Making me think I messed up an ABS sensor while doing the break pads somehow.

Update. Picked up the MX+ scanner and it turned out to be the front right ABS sensor. Swapped it, and went ahead and did rotors since I was back in there. No issues, and all back to normal. Looking at the old sensor, it didn't appear to have any damage. Best I can figure is a piece of rust fell down by the sensor or something like that.

      2027 GMC Sierra: Official Discussion

      By KARNUT · Posted

      It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.

      It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.
