Frequently Asked Questions
Do I need to have this computer programmed by a dealer?
No. We handle the programming for you. After your purchase, simply provide us with your vehicle’s VIN, and we will program the module so it arrives at your door ready for installation.
Where is the PCM located on my 2006 GMC Envoy XL?
On the 2006 Envoy XL with the 4.2L engine, the PCM is typically located in the engine compartment on the driver’s side (LH side), mounted near the battery or fuse box.
What information do you need from me?
We only need your vehicle’s 17-digit VIN to ensure the 2006 GMC Envoy XL PCM 12596784 is programmed with the correct software and calibration for all of your specific options.
Will this fix my Check Engine Light?
If your Check Engine Light is on due to an internal failure of the PCM (common codes include P0601, P0602, P0606), then this replacement module will solve the problem. It’s always best to have the codes professionally diagnosed to confirm the PCM is the root cause.
Is any other setup required after installation?
In some cases, a security relearn procedure (also known as a CASE relearn or anti-theft relearn) may be necessary. This is a simple procedure that can often be done without special tools and typically involves a sequence of key turns. Instructions are widely available for this process.
