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 to remove old errors from a broken seat mat that are stored in the control unit. Once you connect the emulator, use your diagnostic tool to remove old errors and turn off the SRS warning. Unfortunately, errors related to the system are not removed automatically. Before purchase, please scan your car with a diagnostic tool to ensure your SRS warning is caused by a defective seat mat. FOR EUROPEAN MODELS AND 3-WIRED SEAT MAT.
