I made an account just to post the fix for this, couldn't find it anywhere.... Your mileage may vary but this is what worked for me. After having my alarm go off continuously with the hood ajar message I unplugged the hood latch sensor to fix the issue but in doing so I lost my factory remote start, not an big deal during the summer but now that its 20 degrees out its an issue. I dislike spending $100-$200 to replace a part that works fine because the $1 electrical switch integrated into it broke. The BCM seems to use logic on that pin other than high/low so the fix isn't as simple as twist the wires together. I ended up cutting the sensor/switch pigtail and wiring in a 10k ohm potentiometer and turning it till it worked. For my truck that was ~2100 ohms. The truck harness only utilizes two wires of the three pin connector and one of them is a ground. Solder in the 2100 ohm resistor in between the red and black wires as shown attached (don't forget to put the shrink tube on before) plug it in and the hood switch will be bypassed in the "hood closed" position. keep in mind that you can now remote start with the hood open and peoples hands in there. Use at your own risk. 2015 GMC Sierra 1500 SLE 4x4 5.3L

My 2015 Silverado 1500 4x4 crew cab has about 110000 miles on it. It just started having an issue that I cannot seem to fix. The engine stays running when I turn the key to the off position and remove it. The accessories turn off normally and the RAP seems to be working. Meaning the radio and things turn off when I open the door....this truck is all stuck with the exception of a light bar. I’ve already pulled the light bar fuse at the battery hookup to see if that had anything to do with it and it made no change. Any ideas? Thanks 64187634141__38D880EE-87ED-4441-B214-B90E348CB1F8.MOV

Bought this vehicle brand new. I love it, and perfect for myself, my family, and the fact it's Diesel puts the cherry on top for me. But... now things have started. We have currently 1,137 miles on the vehicle and had the first message populated: - Service steering column lock. (see photo) Everything else worked, remote start, standard start, and the vehicle had zero issues. The following day from our road trip, we had to go to the DMV with our out-of-state paperwork to submit for plates. My wife now received a new message. - Service emissions system. See owners manual. (see photo) She drove to the DMV and left to get the smog paperwork. Then a new issue: - Vehicle remote start isn't working. (see photo) She is in the car and tries to start... Nothing. She tries again. It starts, and she drives it to a local dealer. They come to look and scheduled us for an appointment. She drives the vehicle now, and Onstar now shows the emission issue. ( see photo ) We now can't register the vehicle in California, because, the check engine light is on, emissions warning, and they won't smog it until it's corrected. Awesome... I noticed that none of these issues happened until it updated the software in the vehicle. I'm hoping this is something that can be fixed. I've been looking around for answers and only finding more issues that are all pretty shitty. Sorry, no better way to say it. I've also seen a post of people saying, “deal with it, it's a new breed of vehicles,” etc. I’d challenge that answer. No one should pay this much for a vehicle and face these issues I'm reading about. So here's what I'm going to do, document everything, and I mean everything. This will be for everyone who may have this issue now or who may come across it. My opinion...but I'm not a mechanic, is that there is a massive software and hardware issue with these models. I believe GM internally has to know about this from Dealers, Customer Service, Compliance Reports, etc. I'm sure all issues are in the queue to be address or fixed. I do, however, feel with the challenges of physical hardware that they chose a vendor that was most cost-effective, which is a component of these issues a long with the capability to support the software complexity of the current models. Or maybe I'm just wearing a tin hat, who knows. So, I open this up to you. Any advice, similar issues, outcomes you've faced, and other topics, please comment below. May the journey of dealership visits begin. Hopefully, this journey isn't to long.

Remote start only works when I disconnect and reconnect the battery. It will work for about 5 starts and it stops working. No check engine light. No warning lights, hood is closed, doors are closed and all the fuses are good. 2014 silverado 5.3L

Anyone have a check engine light show up then go away and come back? Code uo129 lost communication with brake control module, UO101 lost communication with transmission Control Module. Went to bed with no check engine light, woke up in the morning for work and noticed the truck would not remote start. When I go in to head to work noticed check engine light. After work ran codes. Shortly after getting codes and using google to research check engine light was gone. Went for a drive never came back on. Woke up this morning it was on again. Can anybody relate?

This winter the alarm started going off after a remote start cycle ends. When the car shuts off (after remote start cycle ends) there will be about a 30 second delay and then the alarm starts going off. I mentioned it to the dealer service and they suggested trying a different FOB before they started digging into it. They obviously had not heard of the problem before. I tried a different FOB and it made no difference. I have searched the internet and haven't seen anyone else mention this problem. I don't have a lot of faith in the service at the dealer, so I am wondering if anyone has any ideas?

I have a 2019 Chevy Silverado 1500 and my key fob only has the lock/unlock, and the panic button on it. I saw that the official Chevy accessories page has the key fobs with remote start, tail gate unlock on them as well. If I get one, will I be able to have the dealership program it on my current truck so I can have remote start or is this only for replacement for owners that already have the same key fob? 5 Button Keyless Entry Remote Key Fob Part No. 84312372 https://accessories.chevrolet.com/product/2019/Chevrolet/Silverado 1500/5-button-keyless-entry-remote-key-fob-84312372?categoryId=12001 Thanks much!

I recently bought a 2020 Trail Boss and whenever I remote start the vehicle, the A/C is blowing on high, how can I disable this or Adjust this?

I have a 2017 Silverado Work Truck. Came with Factory power windows and power locks. It did not come equipped with a keyless entry system from the factory. It does not have any of the modules to add remotes for door lock entry or remote start. Does anyone know of a kit to add these features to my truck?

I am getting desperate for some help on this issue. I bought a 202o Silverado 1500 WT and I have been slowly adding OEM parts to it. I live in New England, so I thought a remote starter would be nice for those cold mornings. My problem is that my local dealer told me that the OEM remote starter isn't available for my truck (something about the software not having that option). I don't know how much I believe this, because an OEM starter should be pretty much universal across the 5.3L engines and computers, right? Well, I asked another dealer, and they said the starter kit isn't showing up as a possible accessory with my VIN#. I then tried to call GM directly, and got absolutely nowhere with the tech support, because the first girl had no idea why it wasn't showing up, and the second one had no idea what I was talking about. She thought I was just wondering why it wasn't showing up as an accessory on the page. I am trying to keep the truck as OEM as possible, because I really don't want a bunch of wire splices and extra key fobs to carry around. My question is, has anyone else been having this issue, and/or is this just a load of b.s. and the starter kit and new key fob with the start button will install just fine? Any information would be greatly appreciated about why my WT can't have the remote starter kit installed. (Last eight of the VIN is LG141071)

so i understand you need ap8 code showing in glove box. im showing ap8 among many other codes? does the mean i have the remote start prepp package?
