Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓Installed a used / junkyard Global A ECM and SPS won't program it to your VIN
- ✓GM SPS / TIS2Web throws "module already programmed" or a VIN-mismatch error
- ✓Used module is still married to the donor vehicle and rejects new programming
- ✓Need a salvage ECM reset to virgin state before a dealer reflash
Won't fix:
- ✗Programming the module to your VIN — we virginize; you (or your dealer) do the SPS write after
- ✗Hardware-failed or water-damaged modules (we reset, not repair internal damage)
- ✗Global B (2019+) modules — those use a different security model, text us to confirm
- ✗Theft-relink / immobilizer key programming (separate service)
Why a used Global A module needs virginizing
GM Global A modules store the VIN they were last programmed to. SPS2 / TIS2Web checks that VIN and refuses to reprogram a module that is already married to a different vehicle. Virginizing clears that marriage so the unit looks like a brand-new part — the only way to make a used ECM/module accept programming to your VIN without buying a new one from the dealer.
