Part Description
This Engine Control Module (ECM) was removed from a 2011 Subaru Legacy equipped with a 2.5L naturally aspirated engine and automatic transmission with Federal emissions. The unit has been thoroughly inspected by our certified technicians and is currently on the shelf ready for immediate shipment. This OEM Subaru part ensures proper engine management and vehicle performance.
The Engine Control Module is the central computer that manages your Subaru’s engine operations, controlling fuel injection, ignition timing, emissions systems, and transmission shifting. ECM failures commonly occur due to electrical surges, water damage, or internal component degradation over time, resulting in poor engine performance, rough idling, transmission shifting issues, or complete no-start conditions. A functioning ECM is essential for proper vehicle operation and emissions compliance.

Frequently Asked Questions
Does this ECM need to be programmed for my 2011 Subaru Legacy?
Yes, this ECM will require programming to your vehicle’s VIN and security system by a qualified Subaru technician or automotive locksmith. We recommend having this done before installation.
Will this ECM work with California emissions vehicles?
This specific unit is programmed for Federal emissions. California emissions vehicles require a different ECM calibration, so please verify your emissions type before ordering.
What are common signs of ECM failure in Subaru Legacy?
Common symptoms include engine stalling, rough idle, transmission shifting problems, check engine light, poor fuel economy, and in severe cases, complete no-start conditions.
Is this ECM compatible with manual transmission Legacy models?

Check your current ECM part number and compare it with our interchange number 52816. Also verify your engine size (2.5L), transmission type (automatic), and emissions type (Federal vs California).
