    Anyone try to program modules lately? - SOLVED

    FINALLY yes. OBDX Pro GT for the win. Just not with this tower I lugged into the garage, apparently. But my Surface Pro 7 worked with it. Does it have the minimum RAM? No. HD space? No. Operating system (Pro)? No. But sure, we'll work now.

    I did poke around there with the Tech2 when I first got the switch, didn't find anything to 'learn' it to the vehicle. Now that the programming is complete, all switches appear to be working. Thanks for putting in the time to try and help.

    Well, I just re-installed Techline connect on the FIRST computer that wouldn't work, and now it's installing. On the first try. I swear, this stuff is going to send me back to carburetors. Thanks all for following along with my insanity. Looks like the OBDX Pro with the right computer works.

    I can try that. My tech2 has always been a little finicky though. Connection errors on and off again. Again, it's one of those things - is it my vehicle or the fact it's a clone?

    Yeah that's going to be the next step, not sure if they're open tomorrow but contacting their support is the only thing I can think of that's left.

    Anyone try to program modules lately? - SOLVED

    I haven't been able to update ANY modules. Same error. The driver's door module contains all of the switches for the windows, mirrors, door locks, etc. When I disassemble it the switches are little plastic rockers that depress a rubber membrane that covers the whole circuit board. There's no...

    Nothing works at all with the new switch. Tech2 sees it but reports that the VIN has not been set yet.

    Driver door window would not go up and down anymore. All other windows would. I can command the window down and up with a Tech2 and it works.

    Still no luck. Same exact behavior. I connect to the truck with the new OBDX Pro GT, it can see the controllers, allows me to choose, tells me the current coding and what's going to be written - go to write, fail. Every time. Antivirus and firewalls disabled. Voltage good. E4491 –...

    Yeah it's a 411 PCM out of an '02, if I remember right. I only ever had VATS removed, it's never been tuned at all and I've been driving it for almost 5 years that way. I'd like to play with some of the shift points, first.

    Yes, got the GT. Apparently the VX(?) is also J2534 compatible, but the GT specifically mentions being able to communicate with low-speed canbus. It should be here saturday. I'm also researching LSDroid, PCMHammer and TunerPro to play around with my LM7-swapped C10.... if I can use this dongle...

    I got tired of messing with it, put the Tech2 away in it's case and just ordered one of those OBDx Pro things. We'll see if that does any better. On another fun note, now there seems to be some kind of draw on the battery happening. I love my truck.

    Anyone try to program modules lately? - SOLVED

    I am not able to reprogram the old driver's module or the passenger module. I haven't tried any others out of fear of bricking them lol. Each time, same communication error when it tries to write. It can "see" the truck, shows me available modules that can be updated, choose and download the...

    Anyone try to program modules lately? - SOLVED

    Unfortunately, no luck this evening. Removed the radio entirely. Disabled antivirus and firewalls completely. Hooked up my battery charger and tried to connect - communication error. I look at my charger and see that it's pushing 15V+, lol. Turned to "motorcycle" mode which seemed to be a more...

    I've been powering the tech2 on a house line, but plugged into the cable where it meets the Candi module, not the tech2 itself. I'll try that too.

    Anyone try to program modules lately? - SOLVED

    Yes, I do have an aftermarket radio but I've had the fuse pulled for it through this entire process since I've read about that issue before. I was hoping that would be enough, do you think it actually needs to be physically removed/unplugged? I suppose that's easy enough to try once I'm ready to...

    Anyone try to program modules lately? - SOLVED

    OK - I've made some progress. Partially I think a hardware issue and a giant part is because I am a moron. So I decided to try a different computer, I read some other posts about making sure you have the minimum hardware covered and admittedly my Surface 7 does not meet that. So I drug an old...

    Anyone try to program modules lately? - SOLVED

    No luck yet. Following the video previously posted, I can get to the point where I can select what kind of module I want to program, but when it tries to connect to the vehicle and get data from the module, I get the error E4399: There was an error retrieving the controller data! Which, when I...

    Yeah, plugged in the new driver's window switch module and nothing works. Dug my chinesium MDI-not-a-2 out and it's not going through it's startup sequence correctly and my computer doesn't seem to "see" it though the USB connection anymore... So I guess I'm off to order one of those Tripp...

    2500 Burb or Yukon XL

    Engines are considered very good and long lasting. The transmissions have a bit of a checkered history... the torque converters are known to fail and then send metal through the whole transmission taking it out. Some people will upgrade the TC in advance, and then also get a tune to change the...

    So I have a clone/china made Tech2 and an MDI2 that I bought a few years ago, to do my own diagnostics and pass-through programming when needed. At the time I was basically told by the ACDelco TDS people that the Tech2 wasn't supported (they were still doing some kind of bypass on demand at the...

    Picked up this dope android head unit for my burban

    I installed the same type of unit, probably made by the same factory in china but under a different brand on Amazon. I had a few issues installing - the plugs didn't actually match the factory wiring, and their support said 'just force them together' lol. I did, but got a terrible electronic...

    I suspect BCM... thoughts?

    Yeah it's been a pain trying to find the issue. What's so weird is if I immediately disconnect and reconnect the battery, all is fine. I've been inspecting the wiring everywhere I can, repaired one section that was causing a different problem. My codes pop on both the high-speed and low-speed...

    I suspect BCM... thoughts?

    Your first video is what mine does when it acts up while driving. Sometimes it happens while it's sitting, however, and when that happens I get a no-crank condition.
