Video tutorial

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.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
