True but that connection is there to charge/maintain an RV battery (it can also provide power for electric brakes) so it has to be direct and the wire sized properly to do that.

Got one of these. Bought some wire at Home Depot (2 wires in one cable). Hooked up the + & ground. My battery maintainer came with an adapter meant for a motorcycle battery which I soldered on to the 2 wires. Just plug it in and let in charge/maintain the battery. I work from home so I don't drive much anymore. I can go 3 to 4 weeks without doing anything and my truck will still start fine but that can't be good for the battery. All the computers the truck has drain the battery even though they go to sleep after a short time.

I made a connector that plugs into the trailer plug to hook up my battery tender. Works great. The only thing is you can't charge at a high rate since the fuse for the trailer power is 40amps. Jay

If you turn off the lane change alert it will also turn off the blind spot alert (at least on my 2021). I turn it off when towing. Jay

Is your air filter dry or oiled? If it's oiled you may have oil on the MAF. Jay

You do know the ECM controls oil pressure & volume. It's possible your tune is the cause of the leak. Jay

Normal operation. The ECM & BCM controls the alternator output and will lower the system voltage when it thinks it can (not much electrical load). This is just a way to save fuel for fuel economy. This is not new to GM, they have been doing this for years. It's in the owners manual somewhere. Jay

Those transponders are passive (at least all the ones I have had) and are not the problem. They work like the chip on a credit card active only when put under a transponder reader.. I would be looking for something interfering with the remote to truck signal. Could be something on the truck or something in the area you live causing issues. Aftermarket wireless cameras have been known to cause issues with keyless entry/starting. Jay

Don't forget the timing light.

The spot is between the cup holders in the console. The purpose is to allow the truck to start if the battery in the remote is dead. Have you tried the other remote? Jay

Maybe - Auto stop/start

Great work/write up. Someone needs to pin this so it's easy to find/see. Jay

I have one in my truck. The auto stop eliminator just remembers the switch position. If you turn it off it will stay that way until you turn it on again. If you can use the dash switch to change from on to off you probably have the ASE. If your switch doesn't change anything you have some other device to turn it off. Jay

On my 2021 you only need a subscription for traffic etc. The navigation works just fine. I can't imagine a 22 (that's really a 21) is any different. The actual updated 22s haven't hit the streets/dealer lots yet. Jay

There is no float. It use sensors like a water/grey/Black tank in an RV. The DEF is allowed to freeze so a float wouldn't last long. Jay

Remember the grape smelling differential lube that GM used in the past?

On my Chev I have a set of winter tires/rims (18") that I put on for the winter. Living at 7000' and driving in the mountains it makes a huge difference. I agree the factory 22" tires are not very good in the snow. Jay

I think I would just remove the one from the other side so it matches. Jay

Center counsel with the Denali/HC/AT4 etc. Not sure on the lower models.

Also the chip shortage probably makes it nearly impossible to get an ECM. Jay

Set up a profile. Jay

Kevin Living in CO those factory Bridgestones suck on anything but flat roads. I have had them on 2 trucks now (19 Denali & 21 High Country). I now have a set of rims/snow tire that I put on around Nov 1st. I got 18" rims because they are cheaper and easier to find tires for. Huge improvement especially braking. Remember that in Colorado if you cause traffic issues in the mountains without chains or 4wd and good tires the fines can be pretty expensive. Jay

#2 same adjustment as the forward collision alert (or what ever it's called). Jay

If you have onstar, go to the web site (mychevrolet.com) and change your password. You will then have to log in again in your truck. Jay
