The Plug-and-Play Solution
Don’t waste time and money at the dealership. We pre-program this module to your vehicle’s specific VIN before shipping. This ensures that it integrates seamlessly with your H2’s existing systems right out of the box. The programming uses the latest GM software updates, resolving common factory issues and ensuring optimal performance. Simply install the module, and you’re ready to go—no expensive dealer tools or additional calibration required for most functions.
Post-Installation Procedures
While this module is designed for plug-and-play installation, some vehicles may require a simple relearn procedure. If your airbag light remains on after installation, a technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules. In some cases, a ‘Brake Pedal Position Relearn’ may also be necessary. Always consult your service manual or a qualified technician for vehicle-specific instructions.
