How do you calibrate an occupant sensor?

Settle the seat weight sensors after the seat is properly set-up by doing this:

1. Drive the vehicle at 22 mph (36 km/h), then park the vehicle on level ground.
2. Turn off the engine and HVAC system. Close the windows and doors.
3. During the calibration procedure, DO NOT sit in or touch the front passenger’s seat.

What are the three types occupant detection system sensors?

Occupancy sensor types include:

• PIR sensors, which work on heat difference detection, measuring infrared radiation.
• Environmental sensors, such as temperature, humidity and CO2 sensors, which detect the change in the environment due to the presence of a human.
• Ultrasonic sensors, similar to radar.
• Microwave sensors.

Where is the SRS fuse?

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.

How do you reset the SRS airbag?

Conclusion – How to Reset Airbag Light

1. Turn your ignition on and off.
2. Restart your vehicle and do a test drive.
3. Examine the passenger airbag switch.
4. Inspect whether seat belts are fastened or working correctly.
5. Verify that the passenger seat sensor is not applied.
6. Use a scanner with an SRS or airbag light reset option.

How does a presence sensor work?

1) The built-in presence sensors that are incorporated into your motion detector pick up on a presence within the area they’re monitoring. 2) Then, the motion detector triggers the secondary tier of your home security set-up, allowing security cameras, alarms and lighting to kick in.

What should I do if the occupant detection system (ODS) does not initialize?

The occupant detection system (ODS) or occupant position detection system (OPDS) may not initialize if there are SRS DTCs or an SRS unit problem. The scan tool is the preferred method for initialization because it has the ability to confirm proper completion. If normal troubleshooting doesn’t resolve the problem, do this:

What is the speed limit for ODS seat weight sensor inspections?

For ODS seat weight sensor inspections 2 and 3, the HDS software requires driving the vehicle 22 mph to properly check the seat weight sensor’s operation and calibration. Driving the vehicle at that speed creates vibrations that remove any binding that could be present in the weight sensors.

How have occupant detection systems evolved over time?

Occupant detection systems have evolved through several configurations and subsystems since their introduction. Through the years, the design of these systems and service manual terminology have also changed, as detailed in this table: First ODS subsystem adopted.

Why won’t the ODS or ODS initialize?

The occupant detection system (ODS) or occupant position detection system (OPDS) may not initialize if there are SRS DTCs or an SRS unit problem. The scan tool is the preferred method for initialization because it has the ability to confirm proper completion.
