Frequently Asked Questions
Do I need to do any programming or flashing myself?
Absolutely not. This module is completely plug-and-play. We program it using the VIN you provide, so it’s ready for installation right out of the box. You will, however, need to perform a simple security relearn procedure, which typically takes about 10-15 minutes with just your key.
What information do you need from me after I order?
After you complete your purchase, you will need to send us your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the 2006 GMC Envoy PCM correctly for your specific options and systems.
Will this fix my check engine light?
If the check engine light is on due to a fault within the original PCM (such as internal processor failure codes), then this replacement module will solve the problem. It’s crucial to ensure the underlying cause of any codes is not a separate faulty sensor or wiring issue.
How do I perform the security relearn procedure?
For most GM vehicles of this era, the procedure is simple: 1) Insert the key and turn it to the ‘ON’ position (don’t start the engine). 2) Leave it on for 10-12 minutes, or until the security light on the dash stops flashing and turns off. 3) Turn the key off for 5 seconds. 4) The vehicle should now start. We include detailed instructions with your order.
Is this compatible with my Trailblazer, Rainier, or Saab 9-7X?
Yes, this PCM is compatible with a wide range of 2006 GM SUVs equipped with the 4.2L engine, including the Chevrolet Trailblazer, Buick Rainier, Isuzu Ascender, and Saab 9-7X. Please check the full compatibility list in the description to confirm your specific model and part number.
