1 x  2in1 small design Seat Occupancy Mat Sensor Emulator (Bypass Unit) CE and RoHS compliant    

 1 x seat belt emulator with original plug (it switches off the unfasten seat belt sound and light)

1 x Installation Instruction

        Instead of an faulty passenger occupancy seat sensor, you can install this emulator, which is a safe and inexpensive solution. The Seat Occupancy Emulator is designed to override your defective passenger occupancy mat and fix you airbag warning light.
      After proper connecting the device to your car’s computer a signal about the presence of a passenger will be sent, even in his absence.


It takes only a few minutes since there is no de-installation of the seat. The control box simulates a permanently occupied passenger seat, and in case of an accident, airbag will ALWAYS deploy - with or without a passenger on the seat.

In some cases it might be necessary to delete the fault with diagnostic device.

 Please be aware: do not not place the child seat on the front seat!
