Warning Signs and How to Overcome Them
If your vehicle is exhibiting any of these symptoms, a failing computer could be the culprit. This module is the definitive solution for:
- ✔ Persistent Check Engine Light (CEL)
- ✔ Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0606, or U0100
- ✔ Unexplained stalling or rough idling
- ✔ A noticeable drop in fuel economy
- ✔ Harsh or incorrect shifting patterns
- ✔ Complete no-start condition where the engine cranks but won’t fire
- ✔ Communication issues with diagnostic scan tools
A Mechanic’s Notebook:
“I had a customer with a 2010 Malibu that was a real head-scratcher. It would stall randomly at red lights, but never threw a consistent code. After chasing down sensors and wiring for two days, we traced it back to an internal PCM fault. We ordered one of these pre-programmed units, provided the VIN, and it arrived ready to go. The security relearn took less than 30 minutes, and the car ran perfectly. The customer went from total frustration to pure relief. It’s a reminder that sometimes the ‘brain’ is the issue, and having a reliable, plug-and-play solution is a lifesaver.”
Guided Installation to Restore Peak Performance
Installing your new 2007-2011 HHR PCM is a manageable task for a DIYer with basic tools. Follow these steps for a successful repair:
- Safety First: Begin by disconnecting the negative terminal on your vehicle’s battery to prevent any electrical shorts.
- Locate the Old Module: Find the existing PCM. On many compatible models like the HHR or Cobalt, it’s located in the engine compartment, often near the firewall or air filter box.
- Disconnect and Remove: Carefully unplug the wiring harness connectors. They have locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket and remove it.
- Install the New Module: Mount your new, pre-programmed PCM in the same location. Securely fasten the bolts and then reconnect the wiring harnesses, ensuring they click firmly into place.
- Reconnect Power: Re-attach the negative battery terminal and tighten it.
- Perform Security Relearn: Your vehicle’s anti-theft system needs to sync with the new PCM. This is a simple procedure, often called a ‘key-on/key-off’ cycle, that typically takes about 30 minutes to complete. Instructions will be provided.

Frequently Asked Questions
Do I need to do anything after I purchase?
Yes. After placing your order, you must send us your vehicle’s 17-digit VIN. We cannot program and ship the module without it. This ensures the software is a perfect match for your car’s specific configuration.
Is this module difficult to install?
Installation is straightforward for most DIY mechanics. It involves disconnecting the battery, swapping the physical module, and then performing a simple security relearn procedure. We provide instructions for the relearn process to make it as easy as possible.
Will this fix my transmission shifting problems?
In many GM vehicles, the PCM (also known as the ECM) controls both engine and transmission functions. If your shifting issues are caused by faulty computer logic or failed internal drivers, this replacement module is very likely to solve the problem.
What is a ‘security relearn’ and why is it necessary?
The security relearn, or anti-theft relearn, is a process that syncs your new PCM with your vehicle’s existing anti-theft system and keys. Without this step, the vehicle will not start. It’s a simple procedure that usually involves a sequence of turning the key on and off over a 30-minute period.
