Remote Start Troubleshooting

[mikez71]

'blindsquirrel' (hptuners forum) mentions that Dorman universal parts, sometimes do weird stuff.
But I haven't heard anything specific to the TCCM... and so long as you can return it, it maybe worth a shot...
(For that matter any TCCM module you are allowed to return)

Wondering why I don't see a single speed TCCM forsale on rockauto?

Here is the thread in case you want me to add something I may have missed..

Remote start not working after swapping 1 speed x-fer case for 2 speed?

Hoping someone happens to know why. (no tune, no log question!) A friend swapped his '09 Tahoe single speed transfer case & module, for a 2 speed case & module. The new unit was from an 07-14 silverado. It works, except his remote start does not. He has a crank abort, YET when he...

Only thing I can think of to check, vehicle speed is 0 before startup.

Thanks for posting tha! Good to get their thoughts for sure. Just FYI, my Tahoe is a ‘13, not ‘09. (First one was an ‘09, sadly was totaled.)

I also wondered why I didn’t see a single speed TCCM. Seems weird.

Yeah vehicle speed shows zero in tech 2 before RS attempt.

Looked at my Tech2, nothing for TCCM! Did you check data display for other modules?

When I look at the EBCM data, it says VSES is failed and not enabled, I don't have any dash lights or DTC's for it..

Remote start will be inhibited if 4WD Low Fault is detected.
- Check TCCM for right OS and calibration.
- Perform actuator relearn.

I'm not sure where to find the TCCM info in the Tech2..

Found a company that does TCCM programming...

GM TCCM Transfer Case Control Module Programming — Ewalt's Auto Tuning

This listing is for a transfer case control module (TCCM) that is programmed/flashed for your vehicle with the newest updates from GM using your VIN to match your vehicle. After you purchase the TCCM you will need to provide us with your VIN so we can program it before we ship it to you. The followi

Transfer Case – Powertrain > Special Functions

See the Tech 2 Pathing document that @Joseph Garcia posted here:

BCM and Tech2

For those that have Tech2's, what all parameters can be changed on the BCM on a 11 Tahoe? If you have a DIC on your Tahoe, I believe that all of the options contained there involve changes in the BCM settings.

Thanks for that! But cannot find it. Could be pathing is correct for other models, but not my 2012.

 

[mikez71]

Looking under ECM or TCM special functions also nothing with TCCM..

Are you selecting the "C" chassis at the beginning? Why not "K" for 4x4?

Should select the 5th character of your VIN.

 

[mikez71]

Oh man, I WAS selecting the C option, thought "C" was for Chevy!

Welp, that makes sense now!
Thanks Fless!! I would have lived my whole life not knowing...
