Car Seat Occupancy Mat Sensor Emulator Bypass for - CLK W209 W203 Seat SRS Emulator Parts The seat occupancy mat is a sensor mounted in the front passenger seat. The emulator simulates a situation of a person sitting in the passenger seat with a seat belt fastened. To make the emulator work, you need a diagnostic tool (such as Autel, iCarsoft, etc.) to remove old error codes related to a faulty seat mat stored in the control unit. Once the emulator is connected, your diagnostic tool will be able to clear the stored errors and turn off the SRS warning light. Error codes related to safety systems do not clear automatically. Before purchase, please scan your vehicle with a diagnostic tool to confirm the SRS warning is caused by a defective seat occupancy mat.
