P059F Active Shutter Code 2022 Refresh - Grill Lights - Need Help

So I recently added 2 light bars to the inside of my grill on my 2022 refreshed GMC Sierra 1500 AT4 with 3.0 Duramax.  To install them I had to remove the upper Bumper cover and grill.  I did not disconnect any wiring or remove/disconnect the active shutter system.  One of the light bars in the 40” M&R system.  It comes with brackets that attach via factory bolts and allows the bar to slide up and down to position in the grill.  The other light is a 20” Dark Knight Nuuk from Strands lighting which I mounted lower in the grill.  See attached pictures.  I buttoned everything up and the check engine light came on.  P059F code which is Active Shutter Performance. The code appears 5-15 minutes after driving.   I cleared it several times and it comes back.  On a previous generation truck I read that this code is thrown when the motor/shutters are restricted and the motor senses a current change.   I checked multiple times and nothing is touching the shutters.  Neither bars or wires. Nothing jammed.  I’m at a loss.  I was thinking these some type of air flow sensor I missed and somehow the lights are impacting airflow and throwing the code.  The shutters appear to work because sometimes they are open and sometimes they are closed.  I was concerned about the truck overheating but the factory coolant temp is slightly south of half way.  My iDash has three coolant temperature gauges and they read between 210-225 after driving for awhile.   Any ideas what to do here.  I feel I’m going to have to pull the lights, clear the code, and see if it returns.  if it does I’ll have to take it to the dealer as it’s still under factory warranty.  I really hate to pull the lights and deal with the dealer so any other thoughts would be much appreciated.  And if anyone knows when these shutters open and close I’d love to know. I’m wondering if I should wait till they open and pull the disconnect the harness vs. leaving it plugged in and risk it staying closed when it should be open. I’m not sure these shutters are for aero purposes.  it seems having the air go through the grill and being met by a wall of plastic is less aerodynamic than leaving them open and letting the air pass through and escape.

Pull the lights and retest.  If the shutter code stays, there's a problem with the shutter.  If so, don't take it to the dealer with the lights installed either.

Thanks for the replies.  Didn’t see any wires pinched.  I loosened the light bar brackets and re-torqued. Took each shutter off, lubed the mechanisms with silicone lube, and reseated them.  Never had an issue since.

Are the light bars worth the cost and labor? How about a shot of the light bar on only from inside the cab at night.

RedLT.  As far as lights I have the M&R 40” light bar mounted in the grill,  a 20” Strands Dark Knight Nuuk lower in the grill, Strands Siberia QB Cube lights (ditch lights) on Putco brackets, and Strands ‘Raptor’ style marker lights.  Everything is wired to an Auxbeam AR800RGB 8 switch controller.  I did the installs myself.  Nothing that complicated but I didn’t want to make any holes in the truck that would be noticeable if I removed anything.  It’s been raining for 2 days and think there’s another 5 coming so I’ll post pics as soon as I can take them.

 

Marker lights - these were $65 for a 3 pack.  They can change from amber to white.  Definitely worth it if you like that look.  Super easy to install. I have the white and amber leads wired to 2 different switches on the Aux beam and tied into the marker lights built into the 20” light bar and cube lights so I can turn them all on at once, either yellow or white.

 

Cube/Ditch lights - Putco brackets are a little expensive but they are nice and made the job super easy.  I love these little cube lights.  They are built well and the pair is under $160.  They have a wide patten that’s super bright and really light up a wide area.  Def recommend these.  

 

Dark knight 20” NUUK:  This is a nice light, definitely light the look.  The way I mounted it makes it difficult to adjust and it’s pointing 20 feet in front of the truck.  Can’t really comment on the performance yet until I adjust it.  I know it should have been done by know.  

 

M&R 40” light bar:  This was $329 from M&R.  I mainly purchased this because of the bracket system.  It bolts right up and allows height adjustment for different grills. Taking the entire front bumper cover off to install it is easier than it seems.  Just need to be careful and have several of those plastic trim removal tools.  I did break a couple of the plastic clips on the wheel well moulding so good to have those on hand.  The second time I had to take the bumper cover off (dealing with the shutter issue)  it took under 25 minutes.  I think the M&R bar would be better but the light is mounted  pretty far back from the grill and the AT4 grill blocks quite a bit of the bar.  I was expecting it to be better and I should have thought about the grill design before ordering it.  I think if installed on a different truck with a less restrictive grill it would work really well.  I also think if it wasn’t mounted so far back from the grill that would help as well.  M&R customer service is great.  I emailed them on a Saturday and they called my back in under 30 minutes.  

 

I also recommend the Auxbeam.  I know there are much better pro grade switches out there but this suits my needs as I’m not driving through streams or competing in Baja anytime soon.  It definitely made the install much easier and cleaner wiring everything to the panel under the hood.   

 

I initially purchased all the Strands lights from Brightsource in Canada.  I couldn’t find any of retailer in the US.  The first 20” bar I got was damaged (not the fault of Brightsource).  So I returned it.  Then it was out of stock with no ETA.  I then ordered from https://www.lumise.eu/. I was a little nervous ordering from Finland and thought the shipping would be crazy but they charged me 225 euros for the 20” light and only 19 euros for shipping.  It came in under a week.  The same light bar at Brightsource was $352.  I recommend sourcing from lumise if you can’t find stateside.  They have  many other lights but not sure how competitive the pricing is on the other brands.  

 

 I’ll try to get you some pics and LMK if you have any other questions.

      Tire psi

      By jgaudet99 · Posted

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.
