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 $$.

Disconnecting the battery negative cable for 30 seconds would be my first step to see if it comes back.   My truck set a code twice that was a lost communication with the transmission. Don't

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.

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.

      Another 6.2L engine failure!

      By KARNUT · Posted

      More is cylinder deactivation. Kia-Hyundai Ive had 4. The warranty is the same 10 years 100K miles. My grandson drives the first one 05 Elantra GT. My wife drives the second one 2011 Genesis. The Genesis still performs as new and looks great. The Elantra looks rough. He’s not kind to it. The third was a Genesis coup. The fourth was a Santa Fe. Those were my daily drivers. I don’t keep them long. Kia is the same as Hyundai with the same warranty. I looked at the K-4 today. Too small, otherwise pretty good buy. Most of Hyundai and Kia’s have a performance upgrade.

      Oil Consumption

      By Grumpy Bear · Posted

      Great question. Answer....depends. One the volume of the crankcase, the driver that will actually be using the vehicle and the amount it uses plus the distance expected for that next trip. Couple of for instances:   Wife is going to drive Dizzy to Moline and back plus a bit around town so say 500 miles on the day. I know from years with that SUV that around town and local rural it uses about a quart in 1250 miles. But on the Interstate and her at the wheel without her anchor nagging her she'll push it and it will drop a quart in about 800 miles. Hence, around town I wait to somewhere between a quarter down to a quart down. On her trip I'd top it if it was down a few ounces and hope for the best.    Have I overfilled one? You mean by adding before it needs a full quart I assume. No, not once after finding the true fill mark.  I know the dipsticks of everything I drive and add what it needs. I learn this by doing the first oil change a quart low. Run the motor for a few minutes. Let it sit over night. Check and mark. Then add half a cup at a time making note of the place on the stick. I add through the dipstick tube with a barbeque basting bottle. Give it a few minutes to drain down and check again.    A vehicle like Dizzy that uses this much oil will take a few quarts between 3K changes. I keep one in the vehicle with the bottle and a bag. (Mindful of it's fullness) Not a big deal and never makes a mess of it. There is no such thing as "multiple quarts' in my shop for any specific oil. There will be a maximum however of the number of different oils used over the fleet.     Dizzy holds a nominal 5 quarts. So the first fill was indeed over as it actually took 4.75. My vehicles are fit with Valvomax valves so I can meter an ounce on the drain if need be. Found her mark first crack at it. Never to be repeated.    Pepper uses none between changes so I don't keep a quart in that one. Straight up 6 quarts put her dead on the full line. Check it ever fuel stop. They will surprise you when they start using.    Raven holds 3 liters or 5.44 ounces over three quarts. I add 3 quarts and 6 ounces. That gives me 5 oil changes on my orphan quart.    Lawnmower holds about 3/5 of a quart. I don't over fill it to prevent an orphan. So yea, depends.

      185k on original 6.2L engine and 10 speed. 6" lift with 35" tires. Changed oil (Mobil 1 synthetic) when truck told me to. Original tranny with original fluid and no service or flush done. All highway miles. A/C compressor replaced at 155k. Oil cooler line replaced at 180k. Still daily driver. Love this truck.   This is my 3rd 6.2L vehicle (2008 Yukon Denali / 2018 Cadillac Escalade) with over 150k miles and no issues. Denali had broken motor mount at 100k.
