Multiple Error Codes - 2017 Silverado 1500 WT

Really at a crossroads trying to find the problem I am facing with my 2017 Silverado 1500 WT, with 85K miles. This all started after 4th of July, went to a touchless carwash. I was throwing 3 separate codes. Also, as of today when I shift into R or D the transmission clunks and the D flashes on the dash, the truck seems to be in a limp home mode. I have replaced the battery with the hope that was causing all the weird electrical issues, but that worked for one drive, then all the lights came back along with 2 additional codes & limp home mode. 

 

The codes I am plagued with are as follows:

  • p10e4
  • p0700 
  • p129d
  • p2534
  • p2535

 

I have crawled around the engine bay and the underside with no obvious signs of damage to the wiring harness. Only thing I can think of is a ground issue, but have not seen other people with this same problem. 

 

Any help would be greatly appreciated!

that thread has a pdf in a reply about a TSB for the p10e4 and p2535 that sets due to water intrusion into headlight housings and/or the connectors to them. i also just had the p10e4, p2535, and p0700 set yesterday. the 2 codes listed will not trip the MIL but will will store the code. the p0700 seems to be a separate issue that i have yet to diagnose on my truck being a generic code that basically says "something is wrong"

 

after doing some quick research, it looks like all of the codes you are experiencing besides the p0700 all have me thinking to have you look into your headlightsand/ or connectors for a start

update to the issues i had on mine, the headlight housing had a cracked housing on the top going from the adjuster around the front and back around the upper mount along with a hole just over the HID ballast, with standing water in the bottom of the headlight. i pulled the headlight out, drained it, scuffed and epoxied the crack back into place with some JB plastic weld. got the pieces to puzzle-piece the hole and epoxied it as well. drilled a couple drain holes in case the epoxy doesnt hold. a $25 repair for now until i can get the funds for a new set of OE housings at a price of $1,200 up to $1,600 (each). the p0700 my truck threw was for the DRL. i would highly suggest taking the assembly out and inspect for cracks or moisture.

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

      Software Update

      By nfisherman · Posted

      I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.

      Exhaust Question

      By newdude · Posted

      Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
