My 2018 Gmc Sierra (55k miles) had the U1510 code this past week. I noticed the check engine light came on after heavy rain day down here in houston. Anyway...the code has to do with the Active Grille Shutter having an electrical short.

Dealer quote @ $750 to replace whole unit. (Parts and labor)..i was fortunate my ext warranty covered it.

I researched the part online..you can buy the part@ $220 and pay your local mechanic shop to replace unit and save $$.

Did you remote start quit working as well?

Got a baffling issue going on.   Couple of days ago the check engine light came on with a 2017 1/2 ton Gas Silverado.    Had a dealer trouble shoot it to run the codes.   It is a communications fault and comes up U1510.    They want the truck for a couple of weeks so they can trial and error a connection or wire issue.   I am reading on-line a LIN communications break down is somewhat common,  maybe with the ECM,  the BCM or other module such as the HVAC.   Anyone seen a common issue with these newer 1/2 tons that can prevent a trial and error approach by the dealership.   I don't really want the truck dismantled while they trial and error the connections.

 

Thanks!

 

Any chance your remote start also quit working? I’m having the same code right now with my 2017 Silverado and the only things I notice different is the remote start doesn’t work anymore and my oil pressure drops down to 20 after idling for more than 20 minutes when not driving.

Check engine light disables remote start.  Oil pressure sounds normal

I have a 2017 GMC Sierra and got a code of U1501 LIN Bus 1. Any ideas?? I've had no issues with performance and local parts store cleared the code saying they have never seen it before.  Will watch to see if it comes back but wanted to see if there were any thoughts on corrective action or maintenance to keep it from happening.

Hello I’m having the exact same issue with my truck it’s a 2017 GMC 1500 sierra 5.3 L 4 x 4 codes that are coming up are U1510 and U1501 can’t figure out the problem what solved it for you?

You all have a 95% chance of needing the active aero shutter that's behind the grille.  The shutter actuator fails internally due to moisture, corrosion, etc. and pulls the LIN BUS communications line which then sets the U1510.  U1510 and a malfunction of the shutter set the check engine light because the shutter is tied in with the ECM.

 

Replacement of the active aero shutter will resolve this issue.

Any of you guys ever get the U1510 code sorted out? I'm having this issue with mine now. I changed the grille shutter last weekend and the light is still on

Well the dealership figured it out, bad connection at the ECM. All the hours of research I did and never saw this fix.

Hope this helps someone in the future figure out there issue.

    • Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.
    • 10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O. 
    • Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.    
    • apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.
    • yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
