Anyone try to program modules lately? - SOLVED

[TrybalRage]

is a long thread but here's what I found on the development of it.

OBDX Development - Developer Tools and Suggestions - pcmhacking.net

I've not used ls Droid but I watched some YouTube videos on it a while back. if you have the older ecm, I hope it works for you.

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.

that will be cool. you'll have to let us know if 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 – Reprogramming Error: Check all connections and reset Programming Interface
E4423 - Programming failed

huh. I was able to update my tcm with it. and a few things on the newer combo.

might email the OBDx guys. they might have an idea.

so what was wrong with the old window switch to begin with?

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.

what is the plug-n-play behavior with the new switch?

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

I'm a bit confused. can you not replace the switch on the drivers door without replacing the module? I changed a passengers rear switch. it was just cheap cheap little switch that pops in and out?


as for programming. can you find something else that has an update available to try? mine had like 32 modules and a few different ones had newer software. I didn't feel like doing anything but the tranny. but that might rule out if it's truck or gm/laptop side.

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 individual electronic switch to replace.
