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 $$.

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.

    • This is NOT impact damage nor neglect. There were previous class action lawsuits because of such paint preparation st GM manufacturing plant. Not just the Cherry Red Color. This paint is applied in three processes to obtain the desired color.  The manufacturer will cover for 36 months or 36k miles only. That rust is actually corrosion because of the paint process failure. Corrosion is covered for 100,100 miles or a certain months. However their corrosion doesn't include this type. Go figure. Clearly manufacturer knew from previous paint issues. This started 3 weeks ago out of the blue.  
    • Is it time to put a piece of tape over the CEL? 
    • consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.
    • can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?
    • Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL
