Restore Peak Performance to Your GM Vehicle
As a technician with over two decades of experience under the hood, I’ve seen firsthand how a failing Powertrain Control Module (PCM) can turn a reliable vehicle into a source of constant frustration. Mysterious check engine lights, erratic engine behavior, poor fuel mileage, and even no-start conditions can often be traced back to this single component—the brain of your engine. If your 2006 Chevy Equinox, Pontiac Torrent, or other compatible GM model is giving you headaches, this professionally programmed PCM, part number 19210070, is the definitive solution to get you back on the road with confidence.
This isn’t just a part in a box. We take the hassle and guesswork out of the repair by pre-programming this module specifically for your vehicle using your VIN. This critical step ensures that all communications between your engine, transmission, and other onboard systems are perfectly synchronized from the moment of installation. It’s loaded with the latest GM software updates, addressing potential factory bugs and optimizing performance beyond the original specifications. By handling the programming for you, we save you a costly trip to the dealership and the need for expensive proprietary scan tools.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2006 Pontiac G6 that came into my bay with a truly baffling set of symptoms. The owner complained of intermittent stalling at red lights, harsh 1-2 shifts, and a cooling fan that would run constantly, even on a cold morning. The check engine light was on, but the codes were all over the place—a transmission communication error (U0101), a throttle body performance code, and a generic internal module fault (P0606). A less experienced tech might have started throwing parts at it: a new throttle body, a transmission solenoid pack. But based on the scattered, unrelated electrical faults, my gut pointed straight to the PCM. After installing a VIN-programmed module just like this one, every single issue vanished. The car ran smoothly, shifted perfectly, and all codes were cleared. It’s a classic case of the PCM being the root cause of what looks like multiple system failures.
Is Your GM Vehicle Showing These PCM Failure Signs?
A failing computer can manifest in numerous ways. If you’re experiencing any of the following, a faulty PCM is a highly likely culprit. Replacing your 2006 Equinox Powertrain Control Module can be the solution.
- ✔ Persistent Check Engine Light (CEL) with codes like P0601, P0602, P0606 (Internal Control Module Memory Check Sum Error/Processor Fault).
- ✔ Unexplained drop in fuel economy.
- ✔ Engine stalling, stumbling, or running rough.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Complete no-start condition where the engine cranks but won’t fire up.
- ✔ Communication errors with other modules (U-codes).
- ✔ Failure to pass state emissions testing.
A Straightforward Guide to Your PCM Swap
Installing your new PCM is a manageable job for a confident DIYer. While a security relearn procedure is required after installation, it doesn’t require special tools. Here’s a general guide:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to allow all modules to power down completely.
- Locate the PCM: On most of these models, the PCM is located in the engine compartment on the driver’s side, often near the air filter box.
- Disconnect Connectors: Carefully release the locking tabs and unplug the large electrical wiring harnesses from the old module. Inspect the connectors for any corrosion or bent pins.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket. Keep the hardware as you will reuse it.
- Install the New Module: Mount your new, pre-programmed PCM onto the bracket and securely tighten the bolts.
- Reconnect Everything: Plug the wiring harnesses back into the new module, ensuring they click securely into place. Reconnect the negative battery terminal.
- Perform Security Relearn: This is a vital step. Turn the key to the ‘ON’ position (without starting) for 10-15 minutes, then turn it ‘OFF’ for 10 seconds. Repeat this cycle three times. On the fourth attempt, the vehicle should start and run, with the security system having learned the new PCM.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the module with the exact software and calibrations for your vehicle’s specific options, engine, and transmission. This ensures 100% compatibility and proper function without needing a trip to the dealer.
Is this part difficult to install?
The physical swap is straightforward for most DIYers with basic tools. The most critical part is performing the security relearn procedure correctly after installation, which involves a series of key cycles as described in our guide.
Will this fix my check engine light?
If the check engine light is caused by an internal PCM failure (common codes P0601-P0606) or a fault the PCM is responsible for, then yes, this will resolve the issue. It’s always best to have the codes read to confirm the diagnosis before ordering.
What is the difference between a PCM, ECM, and ECU?
These terms are often used interchangeably. PCM (Powertrain Control Module) is the most accurate term as it controls both the engine and transmission. ECM (Engine Control Module) and ECU (Electronic Control Unit) are older or more generic terms.
Is there a core charge for my old module?
This listing does not require a core return. You can keep or responsibly dispose of your old, faulty module without needing to send it back to us.
What if I still have problems after installation?
First, double-check that the security relearn procedure was completed successfully. If issues persist, it may indicate another underlying problem with wiring or a sensor that the new PCM is now correctly identifying. Our support team is here to help you troubleshoot.
