Is Your Chevy Volt Acting Unpredictably?

As the brain of your Volt’s gasoline engine, a faulty ECM can cause a cascade of confusing problems, from poor fuel economy and stalling to a complete no-start condition, leaving you stranded.

Real-World Shop Experience
“A customer’s 2013 Volt came in last week with the engine refusing to start after the battery was depleted. The dash displayed ‘Engine Not Available,’ and the owner was convinced a component in the high-voltage hybrid system had failed. After scanning, we found no hybrid faults, but we did find communication loss codes with the ECM. We swapped in a programmed module just like this one, and the gasoline engine fired right up. It’s a common misdiagnosis I’ve seen over a dozen times on these Voltsโthe problem seems complex, but it’s often a straightforward ECM failure.”
Easy Installation for the 2011-2015 Volt Engine Control Module
You can get your Volt back to perfect running condition with basic hand tools. Follow these steps for a successful installation:
- Safety First: Always disconnect the negative terminal from your 12V auxiliary battery before beginning any work on your vehicle’s electronics.
- Locate the ECM: On the 2011-2015 Volt, the Engine Control Module is found in the left-hand (driver’s side) rear of the engine compartment.
- Disconnect Connectors: Carefully release the locking tabs on the electrical wiring harnesses and pull them straight out from the module. Inspect the pins for any corrosion and clean if necessary.
- Remove the Old Module: Unbolt the mounting hardware holding the original ECM in place and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed ECM in the same location and secure it with the original hardware.
- Reconnect Everything: Firmly plug the wiring harnesses back into the new module until they click into place. Reconnect your negative battery terminal.
- Final Check: Start the vehicle. The check engine light should be off, and the engine should run smoothly, restoring full functionality to your Volt.
