Important Installation Notes
After purchasing, please provide us with your VIN so we can program the PCM before shipping. Please note that this module requires a relearn procedure to ensure proper function. Follow these steps for a successful installation: disconnect the battery, replace the old PCM with the new one, and reconnect the battery. Then, use a code reader or scan tool to clear any trouble codes and perform the necessary relearns (e.g., theft relearn using GM systems like Tis2web/Techline Connect). It’s essential to follow these steps carefully to avoid any issues with your vehicle’s performance.
Buyer responsibility: please ensure you have the correct tools and knowledge for a successful installation. If you’re not comfortable with DIY installations, consult a professional mechanic. Additionally, keep in mind that this module is designed for OEM restoration only; it does not enhance or modify your vehicle’s performance.
