Programmed 2007 Escalade ESV ECM Engine Control Module 12589297

Restore Peak Performance and Reliability to Your GM Vehicle

Is your 2007 Cadillac Escalade ESV running rough, stalling unexpectedly, or showing a persistent Check Engine Light? These are more than just annoyances; they’re often signs that the vehicle’s brain—the Engine Control Module (ECM)—is failing. As a technician with over two decades of experience, I’ve seen firsthand how a faulty ECM can create a cascade of frustrating and hard-to-diagnose problems. This isn’t just a part; it’s the central command center for your engine’s performance, fuel economy, and emissions. This replacement ECM is your direct, reliable solution to get your truck or SUV running like new again.

What sets this module apart is our professional programming service. Before we ship it, we flash the module with the latest official GM software, specifically matched to your vehicle using its unique VIN. This means you receive a part that is truly plug-and-play. You can bypass the expensive trip to the dealership, avoid their programming fees, and get your vehicle back on the road faster. This is the same process we use in our own repair shop to ensure a perfect fix the first time.

Is Your GM Truck or SUV Showing These Symptoms?

A failing ECM can manifest in many ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs attention. I’ve personally linked these symptoms to ECM failure on hundreds of GM vehicles.

• ✔ Check Engine Light is on or flashing with codes like P0601, P0606, or U0100.
• ✔ Engine stalling, misfiring, or running rough.
• ✔ A complete no-start condition where the engine cranks but won’t fire up.
• ✔ Noticeable decrease in fuel efficiency.
• ✔ Harsh or erratic automatic transmission shifting.
• ✔ Issues with other electronic systems, as the ECM communicates with them.
• ✔ Failure to pass an emissions test.

A Straightforward Guide to Installation

One of the best features of this programmed 2007 Escalade ESV ECM is the ease of installation. While professional installation is always an option, many DIY enthusiasts can handle this job with basic hand tools. Just follow these steps carefully.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow the system to fully discharge.
2. Locate the ECM: On most compatible trucks and SUVs like the Escalade, Tahoe, and Silverado, the ECM is located in the engine bay on the driver’s side, often under or near the battery tray. On cars like the Impala or G6, it may be near the air filter box or on the firewall.
3. Disconnect the Connectors: Carefully unclip the wiring harness connectors from the old ECM. These connectors have locking tabs; be gentle to avoid breaking them. Inspect the connectors for any corrosion or damage.
4. Remove the Old Module: Unbolt the old ECM from its mounting bracket.
5. Install the New Module: Bolt your new, pre-programmed ECM into place.
6. Reconnect Everything: Securely plug the wiring harnesses into the new module until they click. Reconnect the negative battery terminal.
7. Perform Security Relearn: Your vehicle may require a simple security relearn procedure to recognize the new ECM. This typically involves turning the key to the ‘ON’ position for 10-15 minutes. We include instructions for this easy process.
