Replacing the Airbag ECU on a Fiat 500

Model: Fiat 500 312 - Years 2007-2024
Part: Control unit

This video shows how to replace the airbag ECU when the light remains on along with the error "fuel interruption unavailable, start & stop unavailable" and the seatbelt light stays illuminated. The mileage flashes and various other errors are detected with the ODB11 scanner. The airbag ECU is faulty, and we need to remove and replace it. Before starting the work, disconnect the battery. The ECU is located in the driver's footwell (this is a right-hand drive), under the carpet, and there are some screws to remove. At the bottom, you will find two electrical connectors to disconnect. The website ecuconnection.co.uk offers various reprogramming or repair services for your unit at costs ranging from £49.17 to £162.50. There is also a helpful video guide for removing and reinstalling the unit.
