This critical step guarantees that your engine parameters, transmission strategy, and security features function correctly from the moment of installation.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module is completely pre-programmed for your vehicle using the VIN you provide. It is designed to be a plug-and-drive solution, eliminating the need for special tools or a visit to a dealership for programming.
How do I provide my vehicle’s VIN?
After you complete your purchase, we will send you a message requesting your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.
Is this compatible with other part numbers?
Yes, this ECM is a direct replacement for several service numbers, including 12590032, 12602044, 12603530, 12605843, 12607096, 12630457, and 19210737. Please check your original part to confirm one of these numbers.
Will this fix my car’s problem for sure?
This Programmed 2008 Buick Lucerne Engine Control Module will correct any issues directly caused by a faulty ECM. However, it’s crucial that your vehicle has been properly diagnosed. This part will not fix problems related to other faulty components like sensors, wiring, or mechanical parts.
What is a ‘relearn’ procedure?
In some GM vehicles, after installing the new ECM, a simple security or Crankshaft Variation (CASE) relearn procedure may be required. This can often be done without special tools by following a specific sequence of key turns. You can find instructions for your specific model online or in a service manual.
