Is Your Cadillac, Chevy, or GMC Running Rough?
There’s nothing more frustrating than a vehicle that won’t perform as it should. A persistent Check Engine Light, unexplained stalling, poor fuel economy, or a complete failure to start can disrupt your entire day. These are often symptoms pointing to a critical component: the Engine Control Module (ECM), the central computer of your vehicle’s powertrain. When the ECM fails, it can cause a cascade of problems that are difficult to diagnose. This isn’t just a part; it’s the brain behind your engine’s performance, and we have the precise, programmed solution you need.
Common Symptoms of a Failing GM ECM
- ✔ Check Engine Light: The most common indicator, often with codes related to module communication or sensor failures.
- ✔ Engine Stalling or Misfiring: The ECM may fail to correctly manage fuel injection and ignition timing, leading to rough running.
- ✔ No-Start Condition: A completely failed module can prevent the engine from starting at all, as it controls the fuel pump and ignition systems.
- ✔ Poor Fuel Economy: Inefficient engine operation due to incorrect sensor readings or fuel mapping will cause your vehicle to consume more gas.
- ✔ Erratic Transmission Shifting: The ECM works with the Transmission Control Module (TCM) to ensure smooth shifts. A faulty ECM can cause harsh or delayed shifting.
- ✔ Performance Issues: Noticeable loss of power, hesitation during acceleration, or inconsistent performance.
The Direct-Fit Solution: A Pre-Programmed Engine Module
Don’t let a faulty computer keep your vehicle off the road. We offer a reliable, professionally programmed Engine Control Module that is a direct replacement for part number 12692068 and other compatible numbers. The key to our service is the VIN-specific programming. Before we ship your part, our technicians use your vehicle’s unique Vehicle Identification Number (VIN) to load the latest, most stable software updates directly from GM. This ensures the module is perfectly calibrated for your vehicle’s specific engine, transmission, and options, eliminating the guesswork and the need for an expensive trip to the dealership for programming.

Expert Pro Tip
After installing your new ECM, a Vehicle Theft Deterrent (VTD) relearn is almost always necessary. This is a security procedure that syncs the new module with your vehicle’s keys and anti-theft system. Without it, the vehicle will not start. This procedure requires a professional scan tool with GM programming capabilities (like TIS2WEB or Techline Connect). While we handle the complex engine calibration programming, this final security handshake must be done on the vehicle. Plan to have this performed by your mechanic or a qualified technician upon installation.
