Tried posting in the Scan & Tune section but no replies.

My 6l80E builder has asked me if my new transmission has set any Transmission Control Module (TCM) codes. It seems my code scanner will not read TCM codes. Can someone recommend a reasonably priced scanner that will read TCM codes.

Thanks in advance.

 

If you own and work on a C6, I recommend just getting a Tech 2 clone.

 

I see this Autel for 385.00 !!..don’t buy a “graymarket” one because Autel will not warranty those !!

 

Buy a GM Nano for less than $150.00 so you can check the DTC's without a subscription from GM Delco. You are able to access the controllers to program parameters if wanted, but need to buy a $40.00 2 year license from GM. The Nano does the same as a Tech II.
Here is a you tube of the Nano set up, etc.

I just bought one and set it up on my laptop

 

How about ECM & BCM codes and making changes to any/all of the modules?

If you are asking about the GM Nano, yes it will check all codes without a license, but you need to buy the 2 year license from GM for approx $40.00 if you want to change or remove parameters in those modules. The you tube video touches on how to buy a license, and he removes one parameter in his vehicle. Other simple stuff like removing the theft lock and marrying a radio to the VIN # can be done without a license.

 

Quick break down, and A/C Delco TDS is just used to flash in OEM module firmware into the OEM modules for the C6. If the car is 2008 or older, than TIS2000 can be used for the same OEM firmware flashing instead.

As for BCM type programming like fob learns, radio clearing to remarry, changing the RPO features in the BCM programming, and brake/clutch pedal relearns and such, then this is done in Tech2win software alone with the Nano. Also, Nano will allow scanning of all system, using the Tech2win software that comes with it.

As for ECM type re-progamming of the OEM firmware (tuning), tech II clone, Nano, nor any programs they run, can do this. To after market tune a ECM's OEM flashed firmware, you would need either HP tuner, or EFI live and it module instead.

 

So do I infer correctly that in order to make modifications to other GM brands and years, like a 2014 Camaro, some other software/app is required and that the A/C Delco TDS is for the C6, or is it for just some years, or???

They sure don't make this easy and I've been in the IT business for 30+ years...

TIS2000 will software firmware flash GM brand owned vehicals up to 2009 for the most part (including SAAB), while on the C6 vet, only up to 2008. TDS on line is that transition from TIS2000 software, to the on line software that does all year firmware flashing, including the later vehicles as well.

The Nano is a MDI clone (what GM now uses instead of the Tech II hand held devices since the MGI can run GDS2 as well) that comes with Cracked Tech2win to use for free for Tech II needs (back to 1991), , as well as comes with cracked GDS2V21 for cars from 2013 forward.

List of what uses Tech II(win), or GDS2,

So since the Nano is a MDI I clone, runs Tech2win for free to work just like a Tech II with laptop, runs GDS2 for free, works as pass through module for TIS2000, and TDS on line, For all the vehicles that GM branding owns both domestic and abroad for dealership level diagnostics and repairs. (Deawoo, holden, saab, and such).

And why the Nano can run such software for free ( as well as gm now offering TDS $40 subscription per vin for 24 months as well, since TIS2000 only goes up to 2009), its the change in the right to repair laws from the fall out of manufacturers trying to monopolize the repair software use in their equipment to gouge farmers.

As for aftermarket tuning of the OEM ECM firmware (modding the oem firmware of the module once flashed in), you need something like HP tuner module and software instead. As for how HP tuner works, its a pay credit system per Vin that you need to pay to use the software on the car, and the paid credits are not world wide stored, but only stored on the single turners laptop that the software is loaded and used to aftermarket tune. Hence if someone has you tune, then goes to another tuner, will need to pay the credits again for that tuner to use the software on the car as well.
