Part Description
This engine control module (ECM) was removed from a 2006 Lexus IS250 AWD donor vehicle equipped with automatic transmission. The electronic control unit was originally positioned behind the left headlamp assembly and controlled various engine functions. This part has been professionally inspected by our technicians and is currently on the shelf ready for immediate shipment.
The engine control module is the brain of your vehicle’s engine management system, controlling fuel injection, ignition timing, emissions systems, and transmission operation. ECMs commonly fail due to electrical surges, water damage, or internal component degradation over time. When your ECM fails, you may experience poor fuel economy, rough idling, stalling, or the vehicle may not start at all.
