Where is the seat belt warning wire located in the X-Trail?

The seat belt warning wire in the X-Trail is located in the seat cushion. Most car seats have a pressure-sensitive switch hidden inside the cushion. When the vehicle reaches a certain speed, the sensor is triggered, and the seat belt is not fastened, the alarm will sound. The seat belt is a vehicle safety device designed to protect occupants from harmful movements that may occur during a collision or sudden stop. The X-Trail is a compact SUV produced by Dongfeng Nissan, with a body length, width, and height of 4675mm, 1820mm, and 1722mm respectively, and a wheelbase of 2706mm. The X-Trail is equipped with 2.0L and 2.5L engines, paired with a 6-speed manual or CVT transmission. The 2.0L model features direct fuel injection, while the 2.5L model is equipped with multi-point fuel injection.
Last time I encountered a situation where the seat belt alarm kept going off randomly. After tinkering with it for a while, I found that the wiring under the seat had come loose. In the X-Trail, the alarm wires are mainly hidden beneath the driver's and front passenger seats. Follow the metal buckle of the seat belt, where several thin wires are connected, running all the way into the gaps of the seat frame. That time, I had to lift the seat cover to clearly see the wiring path and discovered a yellow wire whose insulation had been worn by the seat rail. When inspecting, I recommend first removing the two screws on the side of the seat and using a phone flashlight to check the chassis interlayer, as dust accumulation there often causes poor contact. Before working on it, remember to disconnect the negative terminal of the battery; otherwise, it might trigger the airbag warning light, which would be costly to fix.
