Is your 2007 Sierra 1500 acting up? Frustrating issues like a persistent Check Engine Light, rough idling, stalling, or a sudden drop in fuel economy often point directly to a failing Engine Control Module (ECM).

This replacement Engine Control Module, part number 12589297, is the definitive solution to get your truck running like it just rolled off the factory line.

Forget the expensive trip to the dealership and the hassle of scheduling a programming appointment. We handle the critical first step for you. Before this module ships, we will flash it with the latest official GM software updates, precisely matched to your truck using your Vehicle Identification Number (VIN). This ensures seamless integration and communication with all your vehicle’s systems. This isn’t just a replacement part; it’s a direct-fit, VIN-programmed solution designed to restore reliability and drivability to your truck.

A failing ECM can cause a wide range of problems. If you’re experiencing any of the following, it’s a strong indicator that your module may need replacement:

• ✔ Persistent Check Engine Light (CEL)
• ✔ Diagnostic Trouble Codes (DTCs) such as P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault)
• ✔ Engine stalling or shutting off while driving
• ✔ Unexplained drops in fuel efficiency
• ✔ Rough or erratic engine idle
• ✔ Harsh or incorrect transmission shifting
• ✔ Complete no-start condition where the engine cranks but won’t fire
• ✔ Communication errors with other vehicle modules

A Straightforward Guide to Installation

Installing your new 2007 Sierra 1500 ECM is a job most DIYers can handle with basic tools. Since we program it beforehand, you won’t need any special scan tools for the initial setup.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
2. Locate the ECM: On most 2007 GM trucks and SUVs like the Sierra, the ECM is located in the engine bay, on the driver’s side, underneath the battery tray. You will need to remove the battery to access it.
3. Disconnect the Connectors: Carefully unlatch and remove the electrical wiring harness connectors from the old ECM. Inspect them for any corrosion or damage.
4. Remove the Old Module: Unbolt the old ECM from its mounting bracket.
5. Install the New Module: Mount your new, pre-programmed ECM onto the bracket and securely fasten it.
6. Reconnect Everything: Plug the wiring harness connectors firmly into the new module until they click into place. Reinstall the battery and connect the negative battery terminal.
7. Perform Security Relearn: While the module is programmed, your vehicle’s anti-theft system may need to be relearned. This is a simple procedure: Turn the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds. Repeat this cycle 3 times. On the fourth try, the vehicle should start.
