Frequently Asked Questions
Is this module difficult to install?
No, installation is designed to be straightforward for a DIYer with basic tools. The module is typically located under the hood on the driver’s side, near the battery. After swapping the hardware, you’ll perform a simple security relearn procedure (often called a ‘key relearn’) which involves turning the key on and off in a specific sequence. Instructions are readily available online, and it requires no special equipment.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s registration, insurance card, or on a plate on the driver’s side of the dashboard visible through the windshield.
Will this fix my specific check engine light codes?
This 2001-2002 Yukon XL 1500 ECM is the correct solution for codes related to internal processor failure, such as P0601, P0602, P0604, and P0606. If your vehicle has been properly diagnosed with a faulty engine computer, this part will resolve those issues. However, it will not fix problems caused by other faulty sensors or wiring on the vehicle.
Do I need to have my keys reprogrammed at a dealership?
No. The security relearn procedure pairs this new module to your existing keys and vehicle security system. You do not need to go to a dealership or a locksmith, which saves you significant time and money.
Is this a used part?
This is a professionally inspected and verified component that has been tested to meet or exceed original equipment standards. It is programmed with fresh, vehicle-specific software to ensure optimal performance and longevity for your Yukon XL.
