PCM, BCM & Immobilizer via Remote J2534 — GDS2 / SPS
GM module work uses GDS2 (Global Diagnostic System 2) and SPS (Service Programming System) — manufacturer tools that require OEM-level access. We run these tools remotely through your J2534 device so you get dealer-quality results without the dealer.

- We connect via Flexihub and run GDS2 or SPS through your J2534.

Frequently Asked Questions
What GM vehicles do you cover?
Most Chevrolet, GMC, Buick, and Cadillac vehicles from 2004 onward. Call with the VIN to confirm.
What is SPS vs. GDS2?
GDS2 is GM's current full-function diagnostic and programming platform. SPS is the older web-based portal for some models. We use whichever is appropriate.
Can you do a passlock/passkey reset with an existing key?
Yes — passlock and passkey relearns with an enrolled key present are standard AIR session work.
What about late-model GM security systems?
Late-model security varies by generation. Call with the VIN and we'll assess the correct procedure.
