TRNW-2: AC Delco TDS

Thu Mar 27 06:04:12 PDT 2025

I had the same issue Monday after techline connect updated. Called GM they were no help, claimed they haven't had an update in over a month. He didn't like it when I called Bullshit. I just flashed another one last week.

My account isn't locked. Programming just doesn't work. Major bummer. I have a 10L80 that we rebuilt and replaced the valve body. I need to program the new TUN. Can I just drive this thing out?

The quick learn function doesn't work with my Snap-on scanners because it doesn't recognize when the transmission selector position is in Drive. 🙁

Another thread about the use of VPNs violating the EULA and terms of use for TechLine Connect.  The previous thread appears to confirm they will ban your account.

I knew GM was logging IPs and is looking for strange user behavior and location data on how they are authenticating users.

Be aware.

GM has made a big mess it appears with an update, but could be intentional.

Some folks are not being affected and others are.  May be related to their previous crackdown on counterfeit MDIs and some sort of escalation.  I have not seen a resolution yet.  Opus (DrewTech) hasn't made a comment I've seen yet.

The banners have info displayed.

What passthrough are you using?

Here's a long thread about what sorts of things they are cracking down on.  Looks ugly.

I am trying to figure out what led to ACDelco locking my account. I usuall see the warning about the use of counterfeit MDI whenever I visit ACDelco website to log into my account and I thought it was just a warning deterring fake MDI users. I use CarDaq Plus 3 for programming the vehicles I go to work on as mobile programmer. I started having "Access Unauthorized with Destination System" error…

Is anyone else having problems programming a GM today with Techline Connect?

It seems like the J2534 wrapper they made me install is corrupt or
something. ???

I get to the final screen for reprogramming and then it sets an error
saying GDS2 is not communicating with the device. This is after I select
the module for reprogramming and select the programming options. It
should start the reprogramming session at that point but it gives me the
error instead.
