67GTO, I was actually talking to you on there. I've just come across this looking for something else. Did you ever get it or do you still need help? Feel free to message me. You need to VIN program the Radio and the HMI but you'll also need calibrations for your HMI as they probably won't match. The calibrations configure backup camera, the boot logo, icons, etc... It's been months but I'm happy to help if you need.

There actually is a step tunerpro in the GM utility file that will send the VIN command (they're different between the radio, HMI and other modules) but, there's a comparison step (see screenshots) that I can't recall off of the top of my head right now what it compares but it will skip that step if a certain variable in the HMI/Radio is set. I caught SPS sending the command once on one of my test ones but it's the same utility. If I'm bored sometime, I'll dig into the logic and play around with it again. In some cases, it will skip that step though.
Edit: Curiousity killed me. It's reading the MEC, if it's 0, it skips the step otherwise it does the VIN command. In most cases, the HMI will be set to 0 so this step will get skipped which means DPS *usually* won't work.

I need help, and I'm messaging you!Originally Posted by gmman
Oh GM DPS will most certainly work and I wrote a script based off the utility file for the radio Module for it to clear the vin info so it will accept another vin from the BCM. However i use a CAN command to do it because its quicker and sends it directly to the HMI module using a CANalyst-II.
Yeah, I was just showing that as a point. I actually built custom software to use a MDI (or J2534) and sent the command. It's a one-liner........ You can actually do it using a cheap ELM327 too. I've written my own software for the Macchina and the J2534 as there's not really much good stuff out there. Anyways, I tried to help the OP but haven't heard back unfortunately.

Have you had any success? I have a HMI and Radio module from a 2018 Denali that works fine in my 2015 Silverado until I turn the key all the way to "On", at which point I receive the theft locked message. I have a J2534 and would like to give it a try...
Does anyone know what system the new EV Hummer uses? I need to reprogram the air suspension but I haven?t found anything on the new GM electric vehicle architecture yet?
I don?t get email alerts for
This site but yes, it can be done.
Just had a update on regular ol sps2 within the last 2-3 weeks. Sps 3 installed but has not opened for me yet. Speaking of dps i cannot get mine to clear a vin.
I have used SPS3 a few times now. Seems to work much better than before. I used to get connection errors on my factory OEM MDI2. Seems to be a lot better now
Ive had lots of issues on the acdelco website. Mostly "security" errors. What vehicles are using sps3?
Just looked at my Techline Connect and I know I have seen it download SPS3 but it still shows SPS2 on my Techline Connect "Home" page.
I wonder if sps3 will be for the new global b stuff up and coming. Could be a new mdi3? Who knows.
I've done Global B with my MDI2 and SPS2.
Could you help me out I have the him module 2.5 I had it installed to my truck that use to have the 2.0 I got it program with the obd genie but after 2 years I went to start my truck and my radio is just black but if I install my old hmi my radio works fine how can I reprogram the 2.5 to my truck
Can anyone reprogram a global b t93 TCM for my 2023 silverado 5.3/10l80 truck? HP doesn?t support my current service code, so I bought a used TCM with the correct service code and I need it reprogrammed with my vin number.
