What Is Seat Occupancy Sensor? 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.
How does a seat occupancy sensor work? A vehicle’s passenger occupancy sensor detects whether a passenger is in the seat and decides whether or not to allow the airbag to deploy in the event of an accident. If the sensor determines a weight on the seat is not a person, the airbag does not deploy.
What are the three types of occupant detection system sensors? Detection technologies cover a wide range of options to detect the presence, the most common being inductive sensors, photoelectric sensors, capacitive sensors and ultrasonic sensors.
How do you test a seat sensor? Move the seat back in small increments (about 5 mm, 0.2 in) until the driver’s seat position sensor reads NOT NEAR. The seat should be about 55 mm (2.17 in) from the front. NOTE: It takes a few seconds for the HDS to display changes, so wait for about 5 seconds between each movement.
What Is Seat Occupancy Sensor? – Related Questions
What is occupant detection system?
An occupant detection system determines a seat occupancy condition including occupancy of a vehicle seat and a size of the occupant, that is, an adult or a child. The system detects a velocity of the vehicle and compares it with a predetermined velocity threshold.
How do I reset my seat sensor?
Remove the terminal clamp and leave it disconnected for 5-10 seconds to allow the airbag sensor to reset. Then reconnect the battery terminal and turn the vehicle on. With a bit of luck, the light will stay off. If it comes back on then the best thing to do is to take your car in for a diagnostics scan.
What is occupant sensing airbag?
The OWS works with sensors that are part of the front passenger’s seat and seat belt. The sensors are designed to detect the presence of a properly seated occupant and determine if the passenger’s side front airbag should be enabled (may inflate) or disabled (will not inflate).
What is SRS fuse?
Pull out the SRS fuse. In most models, this is fuse #40, located in the lower right corner of the fuse block. The SRS light is a warning light for your supplemental restraint system (airbags). An SRS light means that there is a problem in the system. The fuse will not activate the airbags.
Where are shorting bars used?
Shorting bars are used to short both the terminals of a disconnected airbag connector for preventing sudden deployment or expansion of the airbag. The shorting bars are designed as spring-loaded clips which provides a low resistance path when a power supply is made available or when the connectors are reconnected.
Where are seat sensors located?
They are housed in the center of the steering wheel for the driver and in the dashboard for the front passenger. Both airbags are marked SRS AIRBAG. SRS (Supplemental Restraint System) indicates that the airbags are designed to supplement seat belts, not replace them.
How does occupant classification system work?
The Occupant Classification System (OCS) is designed to classify the weight of the front seat passenger and automatically turn OFF the front passenger air bag under certain conditions. For the front passenger seat, the occupant classification system utilizes sensors that are also monitored.
What is Opds sensor?
OPDS is Occupant Position Detection System
Can an airbag warning light be reset?
You can reset the airbag light on your vehicle from your home garage, saving yourself a trip to the dealership or mechanic. After all repairs have been performed, you can reset the airbag light yourself using a handheld computerized tool purchased from an auto parts retailer.
How do I know if my airbag sensor is bad?
The way you know if the sensor is at fault or not, before scanning your airbag system for faults, is to simply look at the “Passenger Airbag Off” light. If there’s no one in the seat, the light should illuminate. If there is someone in the seat, the light should turn off, signifying that the system is armed.
Why did my SRS light came on?
When this light is on, that means your airbags are deactivated. It means they will not deploy properly if you get into an accident. If your car’s battery has drained recently, it may have also depleted the backup battery that powers the airbags.
Why do airbag sensors go bad?
The airbag battery gets down when your car’s battery is exhausted. This problem often causes the airbag sensor to blink. However, recharging the car’s battery solves the issue, and you should not see the airbag sensor light blinking again.
How much does an airbag sensor cost?
The average airbag sensor replacement cost is between $100 and $600, depending on the car model and labor costs. An airbag sensor costs $50 to $300 and a labor cost of $50 to $300.
What is a Occupant Restraint Controller?
The occupant restraint controller is the computer brain that controls your car’s airbags and related systems. It can be located under one of the front seats, in the dashboard, or under the center console.
What is a occupant classification module?
The Occupant Classification Module (OCM) is located underneath the front passenger seat. The Sensor is located beneath the passenger seat cushion foam. Any weight on the seat will be sensed by the Sensor. The OCM uses input from the Sensor to determine the front passenger’s most probable classification.
What is a sensing diagnostic module?
The Sensing and Diagnostic Module (SDM) may reset itself following a hard braking event on some road surfaces. If this occurs during an aggressive turning maneuver, and then afterwards a potential vehicle rollover event is sensed, the roof rail airbag may unintentionally deploy.
Is there a fuse for SRS?
The fuse block is on the driver’s side of the engine compartment. Pull out the SRS fuse. In most models, this is fuse #40, located in the lower right corner of the fuse block. Turn the ignition switch to “ON” without starting the engine.
