Anyone try to program modules lately?

Hardware specs from AC Delco are here: https://gsitlc.ext.gm.com/userguides/Aftermarket Infrastructure Guideline v1.0.pdf

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 reasonable 12.3-12.4V with the truck key turned on (key off shows 12.7-12.8) and it connects, but again fails to actually write the new data to the module.

I'm not sure what to do at this point. Maybe try that OBDX Pro.

I've never been able to program with this Tech2. Last time I needed to code a module I used my now not-functioning MDI clone.

Maybe try taking all the connections apart clean or blow them out with air and re-attach very firmly, then try again

A service bulletin that mentions the cyber security code on page 3. Not a lot of info, but something about renaming sps folder and relaunching. No idea if it applies to you..

Have you tried reprogramming your old door module just to see if it will program?

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 configuration, then tries to push and goes through 2 retries before cancelling.

Here are the instructions from that service bulletin.

E4491 – Reprogramming Error: Check all connections and reset Programming Interface
E4492 – Cyber Security Access Failure
E4399 – There was an error retrieving the controller data

1. Clear cache.
2. Rename SPS folder in C drive and save on computer. example: This PC > OSDisk (C > Users > (GM ID (six digits)) > sps
3. Relaunch TLC in admin mode.
4. Connect wired MDI. Note: If steps 1 through 4 don’t work, try a different setup if available (computer/MDI/cable)
