Is Your 2009 Traverse Running Rough? Restore Its Reliability.
There’s nothing more frustrating than an unreliable vehicle, especially when it’s the one you count on for family trips, daily commutes, and getting things done. If your 2009 Chevy Traverse is experiencing baffling issues like stalling at stoplights, a persistent check engine light, or refusing to start altogether, a failing Engine Control Module (ECM) is very likely the culprit.

We offer the definitive solution: a professionally programmed 2009 Traverse ECM 12623325, flashed specifically to your vehicle’s VIN for a seamless, hassle-free installation.
Common Failure Symptoms & Your Direct-Fit Solution
A faulty ECM can manifest in numerous ways, often mimicking other component failures and leading to costly, incorrect repairs. If you’re noticing any of the following, it’s time to consider the brain of your engine:
- Persistent Check Engine Light (CEL) with communication error codes (e.g., U0100).
- Engine stalling unexpectedly or running rough at idle.
- Complete no-start condition where the engine cranks but won’t fire.
- Noticeable decrease in fuel economy.
- Erratic transmission shifting or performance issues.
- Diagnostic Trouble Codes (DTCs) pointing to internal module failure, such as P0601 or P0606.
This module is the solution. It arrives at your door programmed with the latest GM software updates, matched perfectly to your vehicle’s unique identity. This eliminates the need for expensive dealership programming and gets your family’s SUV back to the reliable performance you depend on.

Will this fix my vehicle’s anti-theft system?
After installation, you may need to perform a simple security relearn procedure to sync the new ECM with your vehicle’s anti-theft system.
