Which fuse?

I have an '09 Silverado, equipped with a manual shift on the floor for four wheel drive. Recently I've noticed that the "idiot lights" on the dash when I engage the four wheel drive is not coming on. The four wheel drive is actually engaging...we've had snow recently and I've used the 4 x 4 and can feel the front end driving. Also, the light for the "positive traction" feature is not lighting either...the recent snow has had that kicking in as well.

 

The rest of the dash lights appear to be working fine, so I'm assuming it's the fuse that controls these lights. I've looked through the owners manual in an attempt to determine which fuse is blown, but frankly I can't determine which one controls these lights? Again, the rest of the dash lights appear to be working fine. Any help in pointing me there, like possibly showing me a better diagram than the one in the owners manual? Or better yet, just tell me the number of the fuse that corresponds to these lights and I'll switch it out?

No fuse for those lights, all of the lights in the IPC are all turned on and off by the data line messages it receives from the ECM

So then this means???? If both the 4 x 4 and the positive traction seem to be working, should I be concerned about the lights not operating? Does it indicate some other kind of problem (note that I posted a separate question about a recent brake concern)?

brakes have nothing to do with the lights ,

 

take it in ,your thinking waaaay to deep here and have no idea how the truck works,,

 

you have a cluster concern....get it diagnosed by a shop that knows the truck like a dealer.

 

buy an online service manual and start reading ....alldata.com $25/yr

      Tire psi

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol

      You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !

      Some Assembly is Required

      This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.
