2018 Camaro, write VIN to New GM Global ECM The 2018 Camaro's ECM and TCM were destroyed in a front end collision, both were replaced with NEW modules from GM. Using the J2535 Pass-through tool, I subscribed with the VIN # to GM SPS service to reprogram the new ECM with the calibration settings and write the VIN to it. All went well on the upload to the new ECM till the bar graph hit 100% and it then failed with reprogram error. The scanner gives me a P0630 error code which is no VIN written to ECM, and when I check for the VIN on the scanner I get 17 blank spaces. So no VIN has been entered into my new ECM yet.
When I tried to repeat the process to get the VIN into the ECM, the GM SPS software reads the ECM and told me that the new ECM settings were at the latest calibration level and that I was not allowed to reflash the same calibration level. So it appears that the latest calibration settings wrote to my new ECM, but the VIN # of the Camaro body did not. I need help in getting the VIN number into the new ECU, or erase the setting that are saved in there already so I can at least try the process again.
Hope someone out there is familiar with the latest GM SPS system and new GM Global programmable ECMs used after model year 2016.
The ECM part # is 12692070.

also make sure voltage dos not drop you are suppose to use a power supply to keep the cars voltage up but some people get away with a jump box. if I have to do one and I don't have my power supply with me I use jumper cable with my Tahoe running hooked to the car im programming

I have exactly same issue after programming ECM. I even tried to program another new one, but it did not help. P0630 is still there. Have you found the solution? Thanks.
