Important Installation Notes
Before installing your new ECM, please note the following: After purchasing, provide us with your VIN so we can program the module before shipping. This ensures the module is tailored to your vehicle’s specific needs. During installation, disconnect the battery first to avoid any shorts or electrical issues. It’s also essential to follow proper relearn procedures for optimal performance and to prevent any potential problems. For vehicles equipped with theft deterrent systems, a relearn procedure using GM systems like Tis2web/Techline Connect may be required. Please consult your owner’s manual or contact a professional mechanic if you’re unsure about any aspect of the installation process.
