Description The seat occupancy mat is a sensor mounted in the front passenger seat. The emulator simulates a situation where a person is sitting in the passenger seat with a seat belt fastened. To make the emulator work, you need a diagnostic tool (such as Autel, iCar2030, or iCarsoft) to clear stored error codes from the control unit related to a faulty seat mat. Once connected, the emulator allows your diagnostic tool to remove existing errors and turn off the SRS warning light. Please note that errors related to safety systems do not clear automatically. Before purchase, scan your vehicle with a diagnostic tool to confirm that the SRS warning is caused by a defective seat mat.
