Almost a year ago This article gives detailed instructions on bypassing the passenger seat occupancy sensor in 2007-2013 3 series vehicles (E9x). edu. The invention relates to a seat occupancy sensor ( 10 ) comprising at least two switch elements ( 12, 14 ) which can be activated by pressure. You could try checking the sensor mat's resistance when it is occupied to see if you are getting any reading. No lights Occupancy sensor reads 400 ohms with no one on seat so I just soldered 4- 100 ohm resisters I had in series to 2 wires and covered it all on hot melt glue, soldered it to van wires and it worked. com. CAUSE. Didn't know the car seat sensor was something you could order and didn't know it could be conencted that way. In [7], a review of different readout circuit architectures is presented. For the passenger seat there is an occupancy sensor which is a pain to bypass properly. If you still can’t find the correct plug, contact us and attach to your message as exact photos as you can, showing all connections under the passenger seat. (3-pronged) 2. ) The only solution is to replace the sensor. al three parts i connected to Hi everybody! I have broken passenger occupancy sensor in my Altima '07 2. The only drawback to using it is that you should not use a child seat because the air bag will deploy. Dissassemble the part of the Seat where you sit on, change the Sensor, then put everything back together. I didn't wanna just bypass the sensor with resistors and diodes. BMW E46 SRS Warning Light When I bought the car I did so knowing it had the SRS warning light illuminated. When the sensor is released the circuit opens, thus blocking the flow of current. g. E81 / E82 / E87 / E88Model Year: 2004 - 2011. The concept of car seat sensor The car seat sensor is a flexible, contact sensor. Factory Setup: - Adult Passenger FRONT Seat: sensor tells The proposed method relies on a single FSR, which is a sensor whose resistance (R x) decreases with increasing the force applied to it. BMW SEAT OCCUPANCY SENSOR: Q&A on RESISTANCE, TESTING, and REPLACEMENT By chatting and providing personal info, you 2002 BMW X5 trying to believed to have been in an accident but not sure. ” 3. 5-0. Product Specification: Loop Resistance : ≤100Ω Insulation Impedance : ≥20MΩ DC=100V Voltage : Max5. If it is the Seat Occupancy Sensor then yes there are emulators that can by-pass this and they are relatively cheap. After doing some research i found our that we can bypass this sensor. now that fault is gone but I'm stuck with these two faults, and all this happend 1k outside of warranty which, really sucks. You'd need the OE spec for the resistance to find out the ohm rating. I believe that the sensor has 2 resistors as part of the circuit. Body weight applied to the sensor causes the compressions of built As a very important part of automobile safety system, seat belt is closely related to seat occupancy sensor. Even though we used a 2011 335i to perform this repair, this article can be applied to any 2007-2013 3 series with minor modifications to Automotive Sensor Products Passenger Safety Sensors Seat Occupancy Sensor – Hall General Description The Seat Occupancy sensor is a magnetically operated push button sensor with a simple push-fit clip mounting configuration, allowing the passenger safety system to determine the presence of an object or person in a seat. Delta Systems’ Hall Effect Seat Switch indicates operator presence via an electrical signal and contains no mechanical contacts, allowing the switch to operate for 1 million or more cycles. First attempt was using 2 100ohm resistors and a 1N4007 diode. Said elements can be associated with the surface of a seat and are arranged at a certain distance from each other in such a manner that a first switch element ( 12 ) is associated with a first area of the seat and a second switch element ( 14 ) is The occupancy detection sensor operates in the range of 20ohm (fat passenger) to 400ohm (empty seat). The seat occupancy detection function, however, also depends on the type of seat. The purpose of the sensor is to determine whether to disable the passenger airbag based on the weight of the occupant. "Seat Occupied Sensor" (Resistance too small. Introduction Seat-occupancy monitoring systems generally use mechanical sensors that detect weight, pressure, force or acceleration over Shorting the 2 sensor connector wires together will not switch off the light. Your front passenger seat contains a sensor that can tell whether someone is sitting there, and how much they weigh. Our seat An occupancy sensor assembly with a variable-resistance seat occupancy sensor comprises an adapter circuit for connecting the occupancy sensor to a control unit. A seat occupancy sensor has at least two pressure-activatable switch elements, which are assigned to two areas of a seat and are spaced a distance apart from one another and connected in a logic AND operation arrangement.
