Speaking of the built in WiFi, does anyone have a problem with the infotainment system disconnecting from the WiFi and never reconnecting until the truck is turned off and everything is reset? I drive a 2017 Duramax and this happens on every trip multiple times. I listen to Pandora most of the time, so I lose it when this happens. 

There is a software update for the infotainment.   Mine would gr et y out. The update fixes this.

truck.jpg.86edd0e265c15c089179d39a5ebd6a58.jpgI bought a trailer connector and put in a Red 10 ga. wire to the 12 volt terminal. I put a 10 ga Black wire to the Ground. I have approximately 12" of wire coming out of the connector and stripped off an inch or so at the end and curled it, making it easy to connect the Red and Black leads to the wires from my Harbor Freight battery charger. I use this setup everyday. I park in my driveway, not in the garage due to getting a weak signal. Be sure to turn the automatic headlight switch to off. I pull the plug when I leave and hook it up when I am home. No need to unhook this charger at night, it has an automatic shut off. No more popping the hood and slamming it shut to hook up a charger. I also added a wifi extender to cover my whole house.

I have a 2020 Chevrolet Silverado 2500 Highcountry.  They have added a "timeout" to the system that turns ACC to OFF after about 10 minutes disabling the WiFi.  I have tried a few things to possibly circumvent the timeout function including exiting from passenger door, leaving the wireless key fob in the vehicle, leaving it unlocked, etc.  No luck.  I really wish I could find a harness that I can add in that keeps constant power to the wifi module.  Wifi module has to be pretty low power and I have duel batteries in the truck.  Also, would be nice to hack into the infotainment software itself as it is an open source Android platform...  Anyways, if anyone comes up with anything PLEASE POST!  I will do the same.

With the key in the ignition and turned to acc, the truck turns off?  You need the key in the ignition for the acc to stay on.  I use a replacement key that was cut but not programmed. Turns the acc and ignition on, but won’t crank the truck over.

i made an extension cable for this, works well. But if you have a WFCO converter in your camper be aware that after being connected to shore power for 40 hours the converter goes into float mode 13 volts, and this is not enough to charge your truck battery. If we go for a week I just flip the breaker off and then on in the camper converter and all is well in the world

I would like to know what the battery drain is. 2017 Silverado when accessory is on?

Got caught with battery charger/ maintainer quitting when battery is fully charged and does not restart. It’s what they do. I bought a 5amp maintainer. Wasn’t enough. So tried a 7.5 amp one with all the bells and whistles. Battery went from 100% to <75% in a few hours. Back on the charger. Just need to remember to unplug it periodically. I think more than 5 amps is excessive. 
I noticed after snowfall the other night 2” the area around the rear view mirror was clear of snow indicating a lot of heat. Ideas anyone.

For those of us with push start, how do we keep the truck accessory mode on? It times out. We have no key to leave in the ignition. Anyone have success doing this with push button start?

And then you leave the accessory mode on? I assume?

Yes. Regular key. Screen turned off. Dimmer turned all the way down.  Constant drain about 5 amps. I can maintain battery @ 12.6 volts. 
Chevy Duramax. High Country.

    • We have now!  2027 GMC Sierra  Early look, but I'm a GMC guy and so far I think I like the looks of the Chevy better.
    • HD at the moment, are kinda their own deal.  How LTZ sells on those vs on 1500, there is a difference.   They are merging most of the mid trims on 1500.  LT, RST and LTZ are replaced by one trim, Silverado.  LT and RST are a BIG portion of sales.    Bad naming choice aside, the new Silverado trim will offer the spread of options that those three trims offered.  So expect to see things like the tech package for example, and memory seats.  And LT Trail Boss will now just be "Trail Boss" (formerly LT Trail Boss) but will offer content spread like the new Silverado trim will.  The press photos showed the Trail Boss (formerly LT Trail Boss) has access to Super Cruise now, which on the current truck was High Country only.       Here is the Trail Boss interior.  Memory seats and Super Cruise are present.  All things the LT Trail Boss it replaces, and the RST it was based on didn't get on the current gen.  You had to go to LTZ or ZR2 for memory seats, and High Country for Super Cruise.      
    • I installed a Hellwig rear sway bar on my 21 Sierra SLT, it made a huge difference on how the truck handles, no body roll, the trucks much more planted now. Not sure of the suspension differences between the 21 and 26,  if its body roll your having a sway bar will solve it. 
    • So a follow up and my fix. I found in online searches the live data to look at on a scan tool to verify the fuel tank pressure sensor was working.  It showed an spec number towards the lower end of the rang, but in spec.  Then while it was running opened the gas cap and the pressure should change.  It didn't change even a tiny bit.  The data for the purge valve said it was open...never changed. So then I measured the voltages on the plug for the fuel pressure sensor and they matched what it should be.  So local car quest parts had the sensor in stock...it was a bit of a pain to remove and an even bigger one to get it to actually go back in.  It helped to unbolt the driveshaft and bungie cord away from the gas tank to give a bit more room to work. So fuel tank pressure sensor in I cleared the code, and started it up.  I went to the scan tool's live data and... Eureka! The pressure number was different and fluctuated a bit.  So took it on a short drive and pressure number varied saw the purge valve go from closed to open and back to closed.  Drove it to and from work for roughly a week plugged in the scan tool no codes.  I took it in to get tested and passed.  In my state's infinite wisdom (oops meant greed), since I pushed the test with the maximum extensions I have to take it back in by Feb '27 to 'get it back up to date', then my next test won't be until Feb '29.
