DIY RG Colorado SDGM Programming Service — security link a replacement Serial Data Gateway Module to your VIN and push the latest factory calibration updates.
Kit ships with an OBDSync scantool and 2-token redemption serial. Programmed in your driveway over OBD-II.
For all RG Colorado utes (2012–2020) — SDGM is the network bridge between low-speed and high-speed CAN buses; required for inter-module communication.
Security link a replacement Serial Data Gateway Module to your VIN and push the latest GM calibration updates. DIY kit ships with an OBDSync scantool and a 2-token redemption serial — programmed in your driveway over OBD-II.
The Serial Data Gateway Module (SDGM) on your RG Colorado is the network bridge that routes CAN bus messages between the high-speed powertrain network (ECM / TCM / EBCM) and the low-speed body / infotainment network (BCM / radio / cluster). When the SDGM is replaced — usually after a wider electrical fault or wiring damage — the new unit needs to be security linked to your VIN and loaded with the correct factory calibrations before the rest of the modules can talk to each other reliably.
All programming is done in the vehicle via OBD-II using OBDSync on a Windows laptop — no need to remove or ship the SDGM.
Provide your VIN at checkout. We ship the OBDSync scantool with a printed 2-token redemption serial.
Download & install OBDSync (Windows 10 / 11, 64-bit). Sign in and enter your redemption serial to add the 2 tokens.
Plug the scantool into your Colorado’s OBD-II port, select SDGM options in OBDSync, work completed in minutes.
