Airbag ECU repair and crash data reset involve the restoration of a vehicle’s Airbag Electronic Control Unit (ECU) after it has been affected by a crash or collision. Skilled technicians use specialized tools to repair the ECU, addressing any faults or damage caused by the impact. Additionally, the crash data stored in the ECU, which records information about the collision, is reset to its original state. This process ensures the airbag system functions correctly and allows for the safe and effective deployment of airbags in future incidents.
