Thank you for this! I had the code and ordered the parts and replaced it. After I replaced the shutters , the thermometer was not communicating so I unplugged the battery and it works now. But the compass needed to be recalibrated by just driving around! No more check engine light now and I can remote start again!

[@stevelove7236]

Great job on explaining & the video diagnosing the U1510 code. I recently purchased a 2018 GMC Sierra 1500 Crew Cab with only 50k miles & the check engine light came on a day or 2 after I had replaced the truck's original factory battery. I was curious if the new battery or a bad connection with it can cause the check engine light to come on. The battery hook up for my 2018 GMC has a case that goes over the positive side you have to remove to get the battery out so that made me wonder if the battery guy may have not put it back on correctly. I had my mechanic run a diagnostics check & said it was a U1510 code. He read all the possibilities of what could be causing it & because both the heater & AC are working fine he cleared the code to see if maybe if it was from changing out the battery. Next morning check engine light came back on. I am going to send my mechanic your video in the morning to review & see if this maybe the issue. My question is what damage will it cause to the engine, heating & cooling, & electrical components if I wait & keep driving my truck for a while before I fix it ?

[@deltaswift9153]

Did you know what it was? Was it the grill active grill shutter?

[@Dstreet370]

Thank you. My company uses prodemand and it sucks. It's very hard to find information like this on it.

Awesome video thank you! You’re getting me closer to figuring my situation out. My check engine light comes on some days and doesn’t other days. I live in Minnesota and it seems it comes on when it’s been getting colder out. Any thoughts? So yes it’s on again off again situation. Hoping I don’t have to replace the shutter but where do you think I should start looking and have you heard of this situation before

I have same code came up I went put on code reader at auto zone and it said to remove any debri or like something was in coil. So I sprayed it at carwash but engine light still on but the coil it had just got replaced and my auto start won't work the doors on mine are open what part u think I need to get or u think I need to take battery cable off then put back on or maybe a wire is loose but what is the part called just shutters

[@jbee001]

Nice video. Could use some clarification for myself. Is this something that can be done with a standard multimeter and which wires are what?

[@MikesRadioRepairRestoration]

Great video and scan tool. You got some good diagnostic thinking. My 2017 Sierra set U1510 and P2101 at the same time. Is this the Shutters causing loss of data on the LIN hence giving me a false code for the throttle body? Or did both these things crap out at once.

[@garybeck8730]

Can you tell me where the 15amp fuse is? I replaced my battery and they stopped working and threw a shutter code. I wanted to check for voltage

[@bayze6584]

First time seeing your video. Great video by the way. I got the same U1510 code. 2017 Chevy Silverado 1500 Z71 4X4. Watched your video. Called the dealer, purchased a new shutter assembly and installed it with no issues. Simple installation. However, the check engine light is still on and the same code is still popping up. Any ideas on what else it could be?

[@Varelaboy561]

Ever got it fixed?

[@wildlandkid]

Great video Sir, what brand and model scanner are you using, and what are your thoughts?

[@nonyaanon6801]

what color is the lin bus wire? and I have the same code from autozone, but the print out says from Code U1510, Remove Object or debris obstructing active grill shutter assembly? says no suggested parts? Power Train System. what causes this, and is there a way to just not use it and allow it to remain open at all times, since i dont live in alaska and or severe cold place, and just want to remove the check engine icon symbol? Not everone has that diagnostic display, so if i have an electrical dc meter can i do the same? how do you know if its not just a fuse? and where to check to fuse first?

[@oponce0592]

Is the active shutter grille is part of HVAC system ? If so when doing live data stream shouldnt it show a low value? Mine still shows 100% on both shutter position and position command telling me its still good?? Im confused?

[@MrMatt1580]

Great Video, I only had a U1501 and replaced the Air shutters, but since the replacement, I have a U1510 is there anything else that could cause it.

[@MrMatt1580]

I found the issue, the fuse failed for the air shutter and failed in a way where only visible inspection would identify. the fuse is number 47 call "throttle control" on the 2017 Serria Denali engine bay fuse panel

[@GTmoments]

Would this keep the A/C compressor from cycling? Have this code and no A/C

[@jureliado1]

Onix 2021 1000 cc turbo engine has the (code u1345 bus lin control module) here in Chile nobody knows how to repair it. Under your knowledge, where do you think I could start to review? I hope you help me please. thank you

[@terrystoybox]

I have the same 2 codes happening to me currently on my 2018. Did you get this resolved?

[@alchly.s]

Hey bud same thing happened on my 2017 k1500 and it was smoking for a while then the code showed so i know the motor burned out you think you can link the part number or something so i can replace it myself

[@manuelaltamirano5704]

I have a 2018, same code. Does this cause the truck to shake at 40+mph ?

[@atwalveron]

Great video man! Without a professional mechanics scope, is there a way to diagnose the harness to check if the BCM is communicating with the AGS module?

[@2010Rafa3l]

Is there a fuse to check before replacing whole module shutters ?

[@user-xs5ou3gr1l]

Yes it’s the 47 I believe

[@Zabarotropitili]

i finally managed to test the wires. one provides constant 12-13V voltage and the other color wire is dropping/fluctuating a little bit. i dont have a scope to see the signal mode. the engine check engine comes on all the time. if the issue with the shutter, how the actuator pins should react if i test the resistance between the pins of the actutator. want to make sure i should replace the actutator.

[@traildisc155]

If you got power ground and signal lin bus other alternative would be just the shutter assembly

[@Zabarotropitili]

@@traildisc155 the shutter looks to start working after I cleared the code using by a scanner.

[@almal5754]

Appreciate the detailed video. I have a 2017 Chevy silverado and check engine light came on today. No other mechanical issue , code was u1510 “ remove object or debris obstructing active grill shutter assembly “ no other code. Does this mean I need to replace the shutter like you did? Please help!

[@traildisc155]

Most likely you would have to but a diagnostic procedure like i did here would be best to make sure but most the time its this 300$ shutter assembly

[@almal5754]

@@traildisc155 I just don’t want to have to pay an addtl $200 to have a dealer diagnosis it. I was able to remove everything and expose the shutters . You made the replacement look fairly easy. Taking it to a shop it’s labor+part+ diagnostic fee .

Hello, i have the same issue on my 18 Tahoe. I'm wondering, since it's such a common issue, has anyone figured out what exactly goes bad in the circuit? If it's just a resistor or capacitor, I'd rather just fix my grill instead of buying a new one that will do the same thing down the line.

[@lucasmckenzie7023]

Hey man, my 2018 Chevy Silverado 15 is throwing two codes. P2101 and U1510. My check engine light was on for a couple days prior but it ran fine. The truck was sitting for 4 days then when I went to start it now it says reduced engine power and shakes. I left it off for awhile and it ran fine. It is showing that I need throttle body and LIN Bus. Is this correct?

[@mrcamarovp]

Same scenario here , did you get the fix?

[@terrystoybox]

Same here anyone have the fix?

[@kalebjohnson1035]

Literally same things. I need an answer!

[@terrystoybox]

So I had the throttle body cleaned and it took care of the first code. The second code is the shutter assembly in the grill. After changing that out I have been issue free. I think in some way these 2 issues are related.

[@kalebjohnson1035]

@@terrystoybox I’ve changed the shutters 3 times now and code keeps coming back. I’ll clean the throttle body as well and reset codes and see what happens

[@Zabarotropitili]

The shutter was replaced on my GMC but the code u1510 discussed in the video didn't go off. The electricians don't have software for my model and refuse to take over the issue. Probably the temperature sensor was not installed. I think I will deal with it myself. Would be nice to have a wire diagram or description of the wires.

[@traildisc155]

Like in video, theres one power , ground and signal wire. Test them first and if ok then most likely the shutter or less likely the pcm

[@Zabarotropitili]

@@traildisc155 which one is the power cord?

[@Ayetown16]

Question, can I replace the entire AGS for the CEL to be cleared ?

[@traildisc155]

U have to replace the whole thing if the codes and diagnostics prove its faulty because they sell it all together as an assembly

[@sixthinline6]

Will the check engine light reset itself automatically after the new installation? How quickly does it reset

[@traildisc155]

It should if not disconnect neg terminal of battery for 5 minutes

[@6gendj584]

Will this make the truck run sluggish? My 2017 doesn't seem to be getting fuel at times..

[@traildisc155]

No normally no But if the blinds are stuck open and your environment is colder then cold starts do stay colder longer causing more fuel to be gushed in cylinders to heat them up faster

[@yomomma9070]

Is this on all vehicles or just an option for the colder climates and prevailing winds. I've seen these on refrigeration units but never cars. I always thought the coolant thermostat would regulate the engine temp.

[@traildisc155]

Sometimes i guess thermostat aint fast enough according to the engineers who designed this

[@bethmad3449]

It’s just more garbage to put on the vehicle and more for the dealership to get you to come in so they can screw you

How do you unclip the final piece to get the shutters off I’m having trouble doing that

Just so yall know before replacing this parts, you can deactivate the use of this part. It will always break anyway and its pretty expensive. Youll need to call someone who can acces your truck with a computer and he'll take care of everything
