Common Signs of a Failing GM ECM

If you’re experiencing any of the following, a faulty ECM is a likely culprit. Replacing your 2008 Savana 2500 Engine Control Module can resolve these issues:

• ✔ Check Engine Light is illuminated with codes like P0601, P0602, P0606, or U-series communication codes.
• ✔ The engine cranks but refuses to start.
• ✔ Noticeable drop in fuel efficiency.
• ✔ Rough idling, stalling, or engine hesitation.
• ✔ Transmission shifting problems or harsh engagement.
• ✔ Seeming failure of other sensors, as the ECM cannot process their data correctly.

A Straightforward Guide to Installation

Installing your new ECM is a manageable job for a DIYer with basic tools. Follow these steps carefully to ensure a smooth process.

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 Module: On the 2008 Savana/Express vans, the ECM is typically found in the engine compartment, on the left-hand (driver’s) side, often near the back of the engine bay.
3. Disconnect Connectors: Carefully unclip the wiring harness connectors from the old module. These connectors have locking tabs that need to be released. Do not force them.
4. Remove the Old ECM: Unbolt the mounting hardware that secures the old ECM to its bracket. Keep the hardware, as you may need it for the new module.
5. Install the New Module: Mount your new, pre-programmed ECM in place and secure it with the original hardware. Reconnect the wiring harnesses, ensuring they click securely into place.
6. Reconnect Battery: Reattach the negative battery terminal.
7. Perform Security Relearn (If Needed): In many GM vehicles, a security relearn procedure is required. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. This allows the new ECM to sync with your vehicle’s anti-theft system. Consult your vehicle’s specific procedure if it doesn’t start immediately.
