Expert Tech Tip: Why VIN Programming is Non-Negotiable
In vehicles like the Cobalt and HHR, the PCM is integrated with the anti-theft system (VATS/Passlock), transmission controls, and emissions equipment. Simply installing a used, non-programmed module will result in a no-start condition. Our VIN programming service ensures the replacement PCM communicates perfectly with all other modules in your car, just like the original. This is the key to a successful, hassle-free repair, making our programmed 2005-2006 Chevy Cobalt PCM the smart and reliable choice.
Frequently Asked Questions
Do I need to do anything after I install this PCM?
For most vehicles, the module is fully plug-and-play. After installation, you should clear any old codes with a scanner. In some cases, a Crankshaft Variation Relearn (CASE Relearn) may be needed to clear a P1336 code, which can be performed by most professional scan tools.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will receive an email with instructions on how to send us your VIN. You can also add your VIN as a note during the checkout process for the fastest service. We cannot ship your order until we receive your VIN.
Will this fit my Pontiac Pursuit or Chevy HHR?
Yes. This PCM is compatible with the 2005-2006 Pontiac Pursuit and the 2006 Chevrolet HHR (2.2L engine) as specified in the detailed fitment list. We program it based on your VIN to ensure it’s correct for your specific make and model.
What if my original part number is different from 12589998?
This module is a direct replacement for several service numbers, including 12599714, 12597329, 12600882, and more. As long as your vehicle’s year, make, and model are on our compatibility list, this programmed 2005-2006 Chevy Cobalt PCM will be the correct, updated part for your car.
Will this definitely fix my car’s problem?
This PCM will resolve any issues directly caused by a failing computer. However, it’s crucial to ensure your vehicle has been properly diagnosed. This part will not fix problems related to faulty sensors, wiring, or mechanical components.
