Description
Part Description
This Engine Control Module (ECM) was removed from a 2004 Subaru Impreza donor vehicle equipped with a 2.5L naturally aspirated engine. The ECM, also known as the engine brain box, has been thoroughly inspected by our technicians and is currently on the shelf ready for immediate shipment. This unit mounts behind the right-hand dashboard and carries OEM part number 22611-AH522.
The Engine Control Module is the central computer that manages your Subaru’s engine performance, controlling fuel injection, ignition timing, emissions systems, and various sensors. ECM failures commonly occur due to electrical surges, water damage, or internal component degradation over time, resulting in symptoms like rough idling, poor fuel economy, check engine lights, or complete no-start conditions. A functioning ECM is essential for proper engine operation and emissions compliance.

Frequently Asked Questions
Will this ECM need to be programmed for my 2004 Subaru Impreza?
Most Subaru ECMs from this era may require programming or adaptation to your vehicle’s VIN and immobilizer system. We recommend having the module programmed by a qualified Subaru technician or automotive locksmith after installation.
What are common symptoms of a failing Subaru Impreza ECM?
Common signs include check engine lights, rough idling, stalling, poor fuel economy, transmission shifting issues, or complete no-start conditions. The ECM controls multiple engine functions, so failures can manifest in various ways.
How do I know if this ECM will fit my specific Subaru model?
This ECM fits 2004-2005 Subaru Impreza models with 2.5L non-turbo engines. Check your current ECM’s part number (22611-AH522) or contact us with your VIN for verification. Turbo models use different ECMs.
What causes Subaru ECMs to fail?
ECM failures typically result from electrical surges during jump-starts, water damage from floods or leaks, internal component aging, or voltage spikes from alternator problems. Proper installation and electrical system maintenance help prevent premature failure.
Can I install this ECM myself?
While physically replacing the ECM is straightforward, programming and adaptation typically require professional diagnostic equipment. Most installations should be performed by qualified technicians to ensure proper programming and functionality.
What’s included with this used Subaru ECM?
You receive the complete Engine Control Module as removed from the donor vehicle. Programming, installation hardware, and technical support are not included. The unit has been inspected and is ready for professional installation.
