High and Low Temperature Resistance Rail Bus, Car Seat Occupancy Sensor, Seat Pressure Sensor US$2. You'd need the OE spec for the resistance to find out the ohm rating. F40Model Year : 2019 + Previous Generations Does "passenger restraint system malfunction" only mean the seat sensor is malfunctioning though, or are there other potential problems? _____ E90M 6MT Slicktop Single Humper in need of a diet. 2. Please read my disclosure for more info. Be sure your wires go thru the hole in the seat bottom just like the It looks like I need a passenger seat sensor in my 2011 R172. I've pluged 5V into sensor, and unloaded, sensor on Vout pin returns ~4. For the record, I dont recommend that anyone attempt this especially for a street car or one in which you may have a small adult or child in the passenger seat. Release the wire cable (PIC 12 ) 10. 00-5. Could be the wrong version for your vehicle b. I had the recall done and it did not fix the issue and initially had the "resistance too high" issue, I unhooked batter, took seat out the car, unhooked all the connections and rehooked after cleaning the connections with proper cleaner. Hi everyone, please help I have a 2017 Mustang When a weight is placed on the seat, resistance in the seat occupancy mat changes. 7 posts · Joined 2023 Add to quote; Only show this user #1 · Nov 30, 2023. I managed to order a replacement seat sensor from a UK main dealer with an ebay shop for under £200 will be attempting to fit this before my MOT is due in October. Airbag360 modules are equipped with original connector ( exact same as the original sensor in Your vehicle ) Step 1. because a simple on off switch would consist of only 2 wires and there would be no need to any kind of a controller to handle the seat sensor and the airbag control module would be able to handle the workload all Has anyone used or come across one of these? ,i have a malfunctioning seat pad sensor and thought it might just be so the 3. 3 mm x 0. 6 VDC * Current Consumption 0. 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. When a passenger seat on, the sensor will be activated and connect to ECU,if the seat belt is not locked, the alarm from car speaker will remind the passenger to fasten the safe belt . I didn't wanna just bypass the sensor with resistors and diodes. The invention relates to a seat occupancy sensor ( 10 ) comprising at least two switch elements ( 12, 14 ) which can be activated by pressure. If this sensor is not working properly, it can cause the warning light to illuminate. You effectively increased the resistance to infinity by removing the resistor. Introduction Seat-occupancy monitoring systems generally use mechanical sensors that detect weight, The proposed method relies on a single FSR, which is a sensor whose resistance (Rx) decreases Yes, it's the Front Passanger Seat Occupancy Sensor, that is supposed to prevent the passanger airbag from needlessly deploying when the front seat is unoccupied. Outside of these two values, and this does include if the system is damaged, the A Passenger Occupancy Sensor, also known as a Weight Sensor, Seat Mat, or Passenger Occupancy Mat, is installed under the seat cushion.
