Hmmm. Check the orientation of the diode. The diode has to be connected in a manner that allows continuity in the direction away from the #10 pin. Think of it as a one way valve. The stripe on the diode should closest to the #18 (or 22) pin.

 

Try following my original instructions for the 10-18 pins. Push the diode leads in hard. Dont pussyfoot around. I used a pair of needle nose pliers. If it's pushed in well, you won't need any tape to hold it in place.

Got it.  Hopefully this saves someone from having to go back through 45 (at this point) pages of information.

This was on the Duramax forum. I believe it is for a GMT 900. But the principles are likely applicable to a K2. Use this information cautiously. ------------------------------------------------------

OK, After struggling thru the schematics and online mods of past models all evening, I figured it out. This is for a Sierra and should be the same for the Silverado. It involves pushing one Diode in

I was just starting to wade through the 45 pages, perhaps you can save me the trouble.  Which pin does the stripe on the diode 'face', 10 or 22?
 
*Edit* ...and I'm assuming it's still the same on an '18?  Just traded my '14 in last night.

Phil-
What is the diode in the gray plug for?

:) I get asked that all the time. Lol. It’s the dome lamp/Puddle Lamp workaround.

For 2014 trucks, the BCM doesn’t send the full 12V to the Puddle Lamp circuit. This is how we address that.

So that’s not the 10/22 jump, you’re just showing the orientation of the diode?

 

*Edit* Nevermind, I put my glaesses on and saw the other diode circled.

So Phil, the Gray diode isn’t needed on the 16 models? I installed this diode on my 16, noticed the puddle lights now mimic the interior lights, On & Off , as well as the exit lights of the Cab & Taillights diode mods.

The puddle lamp circuit, on its own, will only come on at night when the truck is unlocked... then off when locked.

So if your Puddle lamps are functional now, you don’t need the diodes (unless you’re 2014) OR you want them to follow your dome Lamp.

Thanks Phil.  Yeah they come on during the day, when the doors are opened, and at night when unlocking truck. So puddles comes on every time doors are opened, but  with these diode mods, the Cab/backups/& Puddles at night. So, puddles at Day, & All at night...Thanks Phil, & Thanks to everyone who brought us this mod.

Needle nose pliers are helpful

Did this mod to my ‘15, shortly after I bought it.  There is no daylight sensor for the interiors.  I noticed that when I unlocked the truck, opened any/all of the doors, and if I turned on the interior lights with the ON/DOOR/OFF switch (not with the individual switches) the puddles would come on.  Even driving down the highway, if you flip the ON/DOOR/OFF switch to the ON position, the puddles would light up the sides of the truck.

      2026 DENALI 6.2L

      By pyoung62 · Posted

      I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.

      Can you add a 360° Cameras hard button to a 2021 Sierra?

      By ShowMeShooter1332 · Posted

      I am curious if anyone has figured out a way to add an hard button AUX or 360 Camera switch to the center row of switches. I have a 2021 AT4, and want to split the hill decent button and add a 360 camera button so that you don't have to go into the center display and locate the camera functionality, etc...   My father's 2024 Yukon XL AT4 and it has a hard button, see below. I found this thread on the Yukons, but it seems like there may not be a part number for the 2021 sierras. https://www.gm-trucks.com/forums/topic/255339-adding-hard-button-for-camera-on-2021/ Anyone else figured this out. Seems like it would need to be a custom switch!   I am getting ready to install the auto stop/start eliminator, so would be nice to knock them out at once.     Upvote1Downvote0Go to comments

      Oil Consumption

      By Chuck FB · Posted

      Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.
