Frequently Asked Questions
How does the programming process work?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN (Vehicle Identification Number). Our technicians will use this number to flash the ECM with the correct, most recent software for your specific vehicle configuration before we ship it to you.
Will I need to do anything else after installation?
In most cases, this is a direct installation with no further action needed. However, some vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn), which can typically be done without special tools. Instructions are widely available online for this simple process.
Is this a new or used part?
This is a quality, inspected, and fully functional component that has been sourced from a previously used vehicle. Each unit is thoroughly tested to ensure it meets or exceeds OEM specifications before being programmed and shipped.
Where do I find my VIN?
Your VIN can be found on a metal plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
How do I know this will fix my problem?
While this 2008 Isuzu Ascender programmed ECM resolves the most common causes of engine failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the ECM is the source of your issue. This part is the solution for confirmed ECM failures.
