Frequently Asked Questions
Do I need to do any programming after I receive this part?
No. This PCM is shipped to you fully programmed to your vehicle’s VIN number. In some rare cases, a CASE relearn or security relearn may be required, which can be performed with a capable scan tool or by a simple key-cycle procedure. Instructions are available upon request.
Where is the PCM located on my 2006 Isuzu Ascender?
On the 2006 Isuzu Ascender with the 4.2L engine, the PCM (also called the ECM) is located on the driver’s side of the engine compartment, mounted to the engine block below the intake manifold.
How do I provide you with my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for correct programming.
