I had to take my 2022 Silverado with the Duramax into the dealership due to check engine light on and they also said there was a recall for the shutters. After they got it into the shop and looked they said in the harness for the shutters a wire was pinched that was causing proper signal for the shutters to open and close. I ask how they fixed the issues and their response was, "We moved the harness to the proper location and moved the wire so it was not pinched and all problems went away." My concern is the wire was pinched now they have moved it to me that has weakened the wire if it was pinched bad enough to not get the proper signal. They claim they did not splice it which personally I am 100% against splices in main wiring harness for a permeant fix especially on a brand new truck. So I wanted to just see if anyone else has ran across this issue yet? I am going to have them show me what harness they moved and verify they did not put a splice in the wire before I take the truck off the lot.

This is the recommended fix from GM:

The fix: dealership service technicians are instructed to add a tie strap to the wiring harness, which will secure it to the vehicle and ensure it does not contact the active grille shutter while it’s moving. These repairs will be performed at no cost to the vehicle owner.

Thank you, my only concern is still there was a pinched wire that was causing all kinds of issues in this wiring harness. My main question is shouldn't the harness be replaced if there was even "just a pinched wire" to prevent issues down the road from that wire being weakened?

If the wire was pinched and there is wiring damage, the service "recall" is to replace the aero shutter assembly and re-secure the new wiring.

I would think they should but the dealer told me and I quote, " We moved the harness so the wiring was not pinched anymore to let the wire transmit proper signal, and that was the reason for all the check engine lights for the ECM and TCM was the wire was pinched enough to not let the proper signal to transmit through it."  To me if a wire is pinched that bad then it should be replaced and not spliced. Am I over thinking this issue?

Yes, they have guidlines to follow and thats what they do, some may be pinched alot more than others,road conditions and driving habits, stops,starts etc could have a lot to do with how hard the wires are pinched if they are pinched. Some may be pinched and others may not be. 

They are not going to replace parts if not needed. the word pinch itself is a word that can have many degrees of pressure. 

Let the dealer perform there job.

As a former service rep for a global company, pinched wires may not have any internal damage. I've seen it several times There are a few ways to verify that too. My question is how did they know a wire was pinched if it's in a covered harness?

My issue would be that they are treating you like an idiot.  A wire carrying electricity cannot have the electricity stopped by kinking or "pinching" the wire.  Electricity don't give a damn. If that truly was what caused the money light to come on, then it was not "pinched", it was severed.  They are talking about it like it is a washer fluid hose or something.  

 

I would not be worried about them splicing it.  If the ever splice fails, then the money light will come on again, and then they will replace the harness or the whole shutter assembly.

Do you have the actual TSB for this?

 

I had the CEL come on tonight and the fans are acting weird. Thinking this could be the issue. I have U0284

      Tire psi

      By Chuck FB · Posted

      And so you had gone through the process of registering and updating the tool and so on ?. All I can say is that on the front page as the tool fires up you go to advanced mode, then vehicle model comes up and you choose Silverado ( not the DRW or EV  since your a single rear wheel ) , then I think its choice 2 which is 07/2021 - 12/2026 ( 433mhz 13542523 ) as that is the series of tpms sensors and then go down to choice 5 which is tire type/pressure selection. Hit yes and it says to connect to OBD port and turn ignition on.    Having said this, I updated the software in my tool lately and these year range choices look different from the past due to them doing some updates it would appear and I have not connected up to the OBD port since last year so hopefully I am not in for a surprise with them screwing up the software and that it won't work on my truck anymore either.    So my question is, when you plugged into the OBD and started your truck it had that message on the Autel screen "vehicle not supported" ?. That does seem odd as tire shops would be pissed right off if hey can't use their tool on the model year after mine that in theory is supposed to be much the same truck ... unless GM did some change in the computer system to block certain things from access.

      Understanding and using modern scan tools is its own body of knowledge. I had little hope that would work...programming access to the BCM is probably required and that is not easy for us consumers. Expensive scan tool, GM programming subscription, online authentication, etc.   It also may be a matter of finding the right dealer to program it for you. Flashing a modern BCM might be a little too advanced for most tire shops.

      AUX switch install

      Update for anyone following:    Installed everything as shown in diagram. Opted for 8 AWG from Battery Positive to a 50A resettable inline breaker. 8 AWG is tied into to 2x 12 AWG wires feeding a 6 way fuse bus in parallel (manufacturer’s design of what I purchased).    4 of the 6 fuses available for circuits are tied to terminal 30 of each relay. I tied a jumper from one of my spare circuits off the bus to terminal 86 of each relay. The trigger, terminal 85, was pulled from my interior by way of T-Taps from the X61A-X5 pins 10, 11, 17 and 23. This was the hardest part of the job. Even with the X61A unbolted and the X5 removed - there was VERY little wiggle room.  I added back up lights that I want to come on with my cargo lamp - but when I would check continuity between S48A-X1 pin 18 to its respective landing point on the X61A-X5 it triggers the factory relay… Instead I opted for a add-a-fuse on the passenger interior fuse panel (fuse location 10 - cargo lamp) and ran it through the boot on the driver side to my load. Did this to avoid introducing any electrical gremlins.   Note: Please check for continuity between the S48A-X1 and the X61A-X5. In my case wire colours were not the same as other’s who have posted. To do a continuity check you need a Multimeter. Completely disassemble the S48A-X1 and remove the brown face plate off the X61A-X5 by way of a flat head screwdriver - this was the only way I could get any results.   The outputs, terminal 87 of the relays, were fed into a junction box and landed at Individual studs and were labelled Aux 1-4.    At this point, all you need to do is run wire to your loads and bring them to ground. I created a negative bus in the engine bay, all my negatives land here.    For anyone having issues with all of your new aux switch lights coming on with the press of one - I noticed this only to be an issue when the battery wasn’t hooked up to my relays? No idea why, but it was quickly corrected by having my system buttoned up and functional.

      Well I ordered the Autel ts508, and it won't work on my truck I tried all the 2023 and everything it just says vehicle not supported lol   I'm able to send this unit back, so I'm going to do that, then I'll just stop into a some tire shops and if none of them are able to do it, I guess ill have to spend a bunch of money to get a good scanner..... Thanks GM lol

      Needing this part.

      By B07 · Posted

      Don't need the air tube but that's how everyone sells them. Most places won't remove that one piece and sell it alone. No money to be made. Hoping someone swapped theirs out for a CAI and no longer wants it. Not asking anyone to give it away. Offering to buy it but I don't need the tube. It's held on by a hex head screw and nut. Been all over eBay.
