Shift motor wont line up

Just an opinion, but I don't think there's a need to continue to quote and answer the same question in different posts. From a personal perspective it makes this difficult to read.

A cheap OBD reader is not going to read chassis codes.

NOTE: If you can turn the rear driveshaft by hand, you should be able to rotate it slightly so as to be able to turn the TCase shaft to change TCase modes with a pair of channel locks.

Depending on what your "cheap OBD" device is you 'may' be able to read any or all codes in the vehicle.

It's all in the choice of app or software.

With a $15 bluetooth OBD adapter and the right phone app you can absolutely read your 2003 GM vehicles TCCM (Transfer Case Control Module) codes.

That said it doesn't seem like a code is your current issue.

I stand corrected; it's the software that can read those codes. I was thinking about a standalone reader, not a Bluetooth dongle and an app.

I agree in that an inexpensive "code reader" is unlikely to read much beyond the usual engine and emissions systems related codes.

An ELM type device either bluetooth or wifi or even wired USB with a good phone app can read and reset codes from most modules.

Those with good techy skills can even go hands on and use just a "dumb terminal" app and do the communications themselves. That route is most definitely NOT for "the masses" though

It's a $15 hyper though from Walmart.
Thank you for the tip. I didn't know that . That's actually pretty cool. I'm going to have to get a little more educated on that and try that out.
