  2. Rear locker light flashes intermittently - dealer can't/won't fix

    I have an additional light for the combination front/rear lockers that is not coming on. Does that rule anything out?
  3. Rear locker light flashes intermittently - dealer can't/won't fix

    I'm having an intermittent issue with the rear locker light flashing and this symbol popping up on the dash: I took it to the dealer, along with a video of the two lights, and they didn't repair anything, saying, "No codes in system. No lights on dash. Actuated rear locker and released...
  4. Would you advise your loved ones, your friends and relatives to own a Jeep Wrangler?

    No for two reasons: 1. Steering (you have to keep on top of it) 2. Price (it's overpriced for what it is) The "No" vote is silly because my reasons have nothing to do with it breaking down or something awful happening. Actually, I'm pretty pleased that the only problems mine have suffered are...
  5. What did you NOT KNOW about your Jeep until today?

    Some vehicles built during 2021 were shipped despite a chip shortage which affected that AND your auto-dimming mirror from operating properly. If you're still under warranty, take your vehicle to the dealer and show them the problem and they'll be able to resolve it by installing the missing...
  6. Analysis Paralysis - (Help me choose my next tire)

    By the way... is sound level on the road a concern?
  7. Jeep Wrangler Windshield Cracks: A Rite of Passage

    Fun fact! Not all of our windshields fold down, as I learned the hard way. It seems that if you have a Sky One Touch roof on your vehicle, your front windshield will not fold down unless you disassemble and remove the entire top from the vehicle!
  8. Save $ on oil/tire change after Jeep Wave?

    I've got a great dealer and I'm looking to stick with them for tire rotation / oil change. Now that my Jeep Wave has expired, what's financially going to be my best bet to get those services done? Is there some sort of package deal / coupon kind of thing available for bulk oil changes on the...

    "Battery Energy Control Module Internal Performance" - I wonder which battery this is for? (Sounds related.)
  10. JEEP HACKING CAN-C / CAN-IHS / UDS ! (Reverse Engineering)

    I know that Jeep had a problem with the HVAC that they fixed with a firmware update. The firmware update was already applied to my 2021 June Wrangler, what month is your Wrangler?
  11. JEEP HACKING CAN-C / CAN-IHS / UDS ! (Reverse Engineering)

    Here's the latest idea for a new format for the Wranlger CAN bus spreadsheet: The new format is machine readable, making it something that is easily imported into ChatGPT as a cut-and-paste CSV file. Here's a selected sample of the new spreadsheet, in CSV format (to cut-and-paste into...
  12. JEEP HACKING CAN-C / CAN-IHS / UDS ! (Reverse Engineering)

    I agree! Or when (ChatGPT 3.5 in particular) doesn't know, so it starts hallucinating a response. In our specific situation, I was able to work around nearly all false solutions by specifying the exact versions of the language and modules, which put an end to most if not all of that nonsense...
  13. JEEP HACKING CAN-C / CAN-IHS / UDS ! (Reverse Engineering)

    Yes. I'm trying to create a prompt for you guys. Once someone hands you the right prompt, coding with ChatGPT is effortless. It's starting to look like the solution may be outside the bounds of what ChatGPT 3.5 can do. It hallucinates solutions. I'll make sure it works cleanly with ChatGPT 4.0...
  14. JEEP HACKING CAN-C / CAN-IHS / UDS ! (Reverse Engineering)

    I've spent the past few hours arguing with ChatGPT because it doesn't know how to convert nibbles into bytes. I guess there's not enough modern books or websites on the subject, so it doesn't know much. I've gotten it to the point where it analyzes everything correctly... UNLESS you've got...
  15. JEEP HACKING CAN-C / CAN-IHS / UDS ! (Reverse Engineering)

    I was thinking of changing the format of the spreadsheet to make the position of the data more clear than $XXXX????00?? and to make it so that it can be read by machine tools such as GPTchat. Please visit the link, take a look, and let me know.

    Version 1.1 of the Read OBD Values script has been released. The new version can take an extended command line parameter, such as: obd2 0x04 0x05 0x06 0x07 0x0A 0x0B 0x0C 0x0D 0x0E 0x0F 0x11 0x1C 0x1F 0x20 0x21 0x2C 0x2D 0x2E 0x2F 0x30 0x31 0x32 0x33 0x34 0x3C 0x42 0x43 0x44 0x45 0x46 0x47 0x49...
  17. What did you do TO your Jeep JL today?

    I used my Raspberry Pi to record OBD-II data for several minutes as I drove 80mph (the speed limit) on a toll road. I then used ChatGPT 4.0 to analyze the data and give me a maintenance recommendation: Based on the provided data, a few observations can be made: Engine Load: The calculated...

    Cool! Here's a shell script that will pull ALL the OBD2 parameters in order. You'll find that some of them are broken in a really obvious way. I might circle back around to fix those, but if there's one or more you particularly need, let me know. #!/bin/bash # loop through each value in the...

    Interesting enough, if you use the following prompt with ChatGPT: The following parameters describe a 2020 Jeep Wrangler Unlimited with a 2.0L turbo engine at idle. Does anything stand out to you? [COPY/PASTE YOUR PARAMETERS HERE] Then it will comment on your engine's statistics: Based on the...
