Item Description

The emulator simulates a correctly functioning seat occupancy sensor (seat mat), making the vehicle detect that the seat is always occupied. It sends the same signal to the airbag control unit as a seat mat does when a passenger is seated. This device simulates a person sitting in the passenger seat with the seat belt fastened. To use the emulator, you will need a diagnostic tool (such as the latest models from Autel, Bosch, iCarsoft, etc.) to clear any existing errors from a defective passenger seat mat stored in the airbag control unit. Once the emulator is connected, your diagnostic tool can remove the old errors and turn off the SRS/airbag warning. Please note that errors related to other safety systems cannot be cleared automatically. This emulator is intended as a diagnostic device to verify that the car installation is working correctly and that any dashboard errors are caused by a faulty seat occupancy sensor. ⚠️ Please ensure you have the same plug before purchasing.
