Restore Peak Performance to Your Vehicle with a Programmed Engine Control Module
Is your 2013-2016 Buick Encore, Chevy Cruze, Sonic, or other compatible GM vehicle suffering from perplexing engine issues? The Engine Control Module (ECM), often called the Powertrain Control Module (PCM), is the central computer responsible for managing engine performance, fuel economy, and emissions. When it begins to fail, it can cause a cascade of problems that are often difficult to diagnose, leading to frustrating and costly repairs. This replacement ECM, part number 22819494, is the definitive solution to restore your vehicle’s original drivability and reliability.
This isn’t just a part in a box. We provide a crucial service that sets our modules apart: VIN-specific programming. Before this unit ships, our technicians will flash it with the latest, most stable software updates directly from GM, tailored precisely to your vehicle’s Vehicle Identification Number (VIN). This ensures seamless integration with your car’s existing systems, eliminating the need for an expensive trip to the dealership for programming. You receive a component that is ready for installation right out of the box.
Symptoms of a Failing 2013-2016 Encore ECM
A failing ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your engine computer may be the culprit:
- ✔ Persistent Check Engine Light: The light stays on, and you may see codes related to sensor circuits (P0100-P0600 series), processor faults (P0601-P0606), or communication errors (U-codes).
- ✔ Engine Performance Issues: Noticeable loss of power, hesitation during acceleration, rough idling, or random engine misfires.
- ✔ Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG is a strong indicator that the air/fuel mixture is not being managed correctly.
- ✔ Intermittent or No-Start Condition: The engine cranks but refuses to start, or starts unreliably. This can be caused by the ECM failing to control the fuel injectors or ignition coils.
- ✔ Erratic Transmission Shifting: The ECM works with the Transmission Control Module (TCM). A faulty ECM can send incorrect data, leading to harsh or delayed shifts in automatic transmissions.
- ✔ Communication Loss: Your mechanic’s diagnostic scan tool is unable to communicate with the ECM, making it impossible to read codes or live data.
The Importance of VIN Programming
Modern vehicles are complex networks of modules that must communicate perfectly. The VIN contains critical information about your vehicle’s specific options, emissions standards, and security systems. By programming this module to your exact VIN, we ensure that it recognizes and works with the anti-theft system (Passlock/VATS), the transmission, the ABS, and all other onboard computers. This plug-and-play approach saves you hundreds of dollars in dealer fees and significant vehicle downtime.
Installation and Post-Install Procedures
Physically installing the ECM is straightforward for a DIYer with basic tools. Disconnect the negative battery terminal, locate your old ECM, carefully unplug the wiring harnesses, and swap the module. However, after installation, a Security Relearn Procedure is typically required. This pairs the new ECM with your vehicle’s anti-theft system and keys. The procedure is simple and can usually be done without special tools by following a sequence of key turns. Instructions are widely available online or in service manuals. In some cases, a Crankshaft Position Sensor (CASE) relearn may be needed to clear certain trouble codes, which requires a bi-directional scan tool.
Frequently Asked Questions
Do I need to take my vehicle to the dealer after installing this part?
No. We program the module to your vehicle’s VIN before shipping. This handles the main programming. You will only need to perform a simple security relearn procedure at home, which does not require a dealer visit or special tools.
What is a VIN and where do I find it?
The VIN is your vehicle’s unique 17-digit identification number. You can find it on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this a guaranteed fix for my vehicle’s problems?
This module will fix any issue directly caused by a faulty ECM. However, it’s crucial to ensure your vehicle has been properly diagnosed. This part will not fix issues related to bad wiring, faulty sensors, or other mechanical problems.
What if my original part number is not on your list?
The part numbers listed (12668866, 12643636, 12663405, etc.) are often interchangeable. If your part number is different, please contact us with your VIN and original part number. We can verify compatibility for you.
Does this part come with a warranty?
Yes, all of our electronic modules come with a standard warranty. Please see the warranty tab on this page for complete details and coverage information.
