17 Silverado U1510 fault code

[J. Houston]

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. 

[yellowwrecker]

How are you getting the K?? Part of the trouble code ?? Though a GM Tech only scan tool or can a cheapy do it ?? 

I have a 2018 Z71 Silverado showing U1510

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.

I have a 2018 silverado it recently started with a check engine light the code that shows up is u1510 k9 whenever i go to remote start it, it shuts off. I manually start it the code won’t show up it runs fine no issues

[NewUsers]

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

[NewUsers]

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.
