Cold weather errors (trailer connection & sensors)

So Roczcqg, your saying if the adjustment in the software fixes the alerts it’s ok? Let’s put this in perspective, you at abc tire to buy a set of awesome AT tires. The shop says, hey one of them had a leak and we patched it. Good as new, Are you ok with that or do you want a replacement?

Or, your cruisen down the road haulin your Razr and family for a weekend in the hills and the trailer brake fuse blows cause GM never fixed the short in the system. You lost control and a family member in the accident. I wonder how you would feel about the software fix then.

If GM during their testing phase, detected the problem we are experiencing, then they developed the fix and applied it. So the truck goes on sale and no one knows the difference because everything concerning the Trailer connection works perfectly. No problem then. Thats in a perfect world. GM missed a few problems during their testing phase ie Trailer functions, Camera views, Infotainment problems etc. GM has issued updates or applied a fix for most of the problems. Once a problem arises, that issue begins a sort of tracking stat. When is becomes prevalent ie by number of warranty claims, calls from dealers or customers, GM starts looking into it. Now GM knew about this Trailer problem back in Feb 2018 and has been working on it since. How hard have they been working on it? Do not know. But they released a fix and now guess what, we get to test and find out the result. I am sure they have ran their own tests but we are the real testers. Now is there a hardware cause for this problem that they are masking or is a software patch good? The software patch could change setpoints, it could change the way the chips react to certain stimuli, It could prioritize communications on the data bus etc. All I am saying is if after the patch is applied and everything works as described by the user manual, Dealerships, GM's info handouts, and the driver has not experienced any problems, then I guess they fixed it.

You will know if the problem is fixed if you shut the truck off with the trailer plugged in see if the lights come on and off with you behind your trailer

That is something to check for sure. It looks like the software update involves an update of the operating system and calibrations to the Trailering Module.

Got my truck reprogrammed this morning (took about 15 - 20 minutes). Unfortunately the temps here are not supposed to drop below 25 for at least the next week. I will post if I notice an desensitization of the sensors from past experiences. I may not know until December if this fix actually worked.

Same here. The timing of this annoys me beyond belief. If it was just software, how did it take nearly a year to correct???

This is only to make some of the worst trucks drivable and eliminate some nuance alerts. The mild and intermittent short is still there. The original fix was to change the trailer module, then the plug and some wire harness. None of that worked. That admitted they new it was a short, they just can’t find it.

The real concern should be long term damage on other electrical components and if it may cause critical failures. Most critical industrial equipment with electronic controls have ground fault indicators with shutdowns to protect the electronics and equipment from damage.

I understand Chevy taking this cheap way around, they are risking a lot. Hopefully it is an intermittent step. I also think the fault will be found if not already. I just hope they have done all the risk analysis to prevent serious failures or possible injuries.

My truck said it was 5° this morning
No warnings or errors popped up
Ran the truck through the car wash night before to get all the connections nice and wet

Put your truck thru the Rough 'n' Tough and let us know how the Trailer System works.

I will try to check as many different scenarios that I can think of

Approx 40 miles of the trip will be on dirt road in Quebec

The forecast is in the 20s with 5 to 7 inches of snow on travel day

Glad to hear it's all sorted out so far! Looking forward to getting mine fixed as well.

Mine is in the shop today getting it’s update. Fingers crossed. And for all of you worried about the temps don’t, I’m in Montana and it’s still cold as hell!!!

The trip went well

The trailer detection system worked

Gm accessory camera that mounts to the rear of the trailer and plugs in did not work so well

Lost connection or truck did not recognize it I still have to diagnose it

The antitheft system is a pain it flashes the leds nonstop When Truck is off and trailer is still plugged in

I may be the happiest man on earth that I have a low mileage 2005 K1500 without all the bells and whistles. No, I take that back, the Apollo 13 astronauts are as the GM engineers weren't in charge of the fix.

This is actually a great post. Very informative. Especially the section named Tips. It clearly shows how Chevy is putting the responsibility for it to work correctly on the consumer. Why would you come out with a new model year and the module will not work with LED bulbs? This is standard equipment on trailers and a very popular upgrade. It is understandable older trucks have issues with LED’s. Why not fix their design on a new model year to work with LED lights?

No different than the dumb windshield washer button midway down the blinker switch handle and the auto headlights a push button on the end of it. Which do you use most.

These new trucks look and run great so we have a great start if we can get Chevy to listen and fix the squirrelly software and electronic parts. They should have a “engineer meet your truck user day” and design to today’s standards and uses. Rain, snow, cold and mud, LED lights etc... Not the soccer mom.
