Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN (Vehicle Identification Number). We will program the 2006 HHR Engine Control Module with this information before we ship it, ensuring it is a perfect match for your vehicle’s systems.
Is this part difficult to install?
For someone with basic mechanical skills, the installation is straightforward. The ECM is typically located in the engine bay. The process involves disconnecting the battery, unplugging the electrical connectors from the old unit, unbolting it, and then installing the new one in the reverse order. Since our unit comes pre-programmed, no special computer tools are required.
Will I need to do anything after installation?
In most cases, the vehicle will start and run perfectly. However, some GM vehicles may require a simple security relearn procedure, which can be done without any special tools and typically involves a sequence of turning the key in the ignition. Instructions can be easily found online or in your vehicle’s service manual.
What does the ECM actually do?
The Engine Control Module is your car’s main computer. It controls critical functions like fuel injection, ignition timing, emissions systems, and transmission shifting by reading data from sensors all over your vehicle. A properly functioning ECM is essential for performance, fuel economy, and reliability.
