What is a Mitsubishi Lancer Evolution III airbag control unit?
The Mitsubishi Lancer Evolution III airbag control unit (ECU) is the central electronic control unit (ECU) of the Supplemental Restraint System (SRS), which is essential for occupant safety in the event of a collision. It continuously monitors sensor data, decides on airbag and seatbelt pretensioner deployment, and stores important crash information. It thus ensures the proper functioning of all passive safety systems.
This state-of-the-art component is crucial for the reliable operation of your airbag system and therefore for the vehicle occupants.
It acts as the brain of the airbag system and must be immediately subjected to a **Mitsubishi Lancer Evolution III airbag control unit repair** in the event of a fault.
