In this video we can see the problem of the airbag light on in a 2019 Fiat 500, not as a result of an accident, but due to a sudden malfunction. The diagnostics reveal error B0105-2D: it is a pressure sensor in the door that detects impacts to trigger the airbags.

Upon visual inspection, both the sensor and the connector appear intact, but the light persists. However, in the flexible belt between the door and the body, where the cables bend with each opening/closing, there is a broken red/gray wire and another with damaged insulation (a common sign of wear).

The solution is to repair the broken wire with soldering and insulating tape, and also reinforce the insulation of the second wire for prevention. After reconnecting everything, the airbag light turns off autonomously, without the need to clear the error.

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.
