The seat occupancy mat is a sensor mounted in the front passenger seat.<br> The emulator simulates a situation of a person sitting in the passenger seat with a seat belt fastened.<br> To make the emulator work you need a diagnostic tool (like for , , etc.) to remove old errors of a broken seat mat that are stored in the control unit. Once you connect the emulator your diagnostic tool will be to remove old errors and turn off the SRS/ warning. Unfortunately, the errors related to the safety systems are not removing automatically.<br> Before purchase, please scan your car with a diagnostic tool to make sure your SRS/ warning is caused by a defective seat mat.<br> These warnings can be turned on by at least 6 sensors mounted in the seat. The emulator solves the problem caused by a faulty seat mat only. The emulator will not solve your problem if a different sensor is faulty - the SRS/ warning light will still be present after connecting the emulator and removing the error present in the diagnostic tool.<br> Name: Car Seat Occupancy Mat Sensor SRS Bypass Emulator<br> Fitment Type: Direct Replacement Install<br> Fitment:<br> for E-Class W211 Saloon/Sedan (production years: 2004-2009)<br> for E-Class S211 Estate (production years: 2004-2010)<br> for C219 (production years: 2004-2010)<br> for S-Class W221 (production years: 2005-2013)<br> for /S-Class Coupe C216 (production years: 2006-2014)<br> Material: plastic<br> colour: As shown<br> Package Contents:<br> 1 x Car Seat Bypass Emulator<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
