B0097 — Right Side Restraints Sensor 2

Generic OBD-II · all makesBody

B0097 indicates a fault in the Right Side Restraints Sensor 2 circuit, meaning the vehicle's airbag control module has detected a problem with the second sensor that monitors the right side occupant restraint system.

Symptoms

What causes it — most likely first

1. Faulty Right Side Restraints Sensor 2

The sensor itself has failed electrically (open, short, or internal failure) and cannot provide the required signal to the airbag control module.

2. Damaged or corroded wiring harness

Frayed wires, broken connectors, or corrosion in the harness leading to the sensor can cause loss of signal or intermittent readings.

3. Loose or mis‑torqued sensor connector

A connector that is not fully seated or has loose pins can create an intermittent circuit fault.

4. Vehicle crash damage affecting the sensor mounting

Impact from a previous collision can deform the sensor mounting bracket or crush the wiring, leading to a fault.

5. Airbag control module software glitch

Rarely, a software error in the airbag control module may misinterpret a good sensor signal as a fault.

6. Failed airbag control module (PCM/ECM)

A malfunctioning airbag control module can falsely report a sensor fault, but this is the least common cause and should be considered only after all wiring and sensor checks are completed.

How it's diagnosed

  1. Connect a compatible scan tool and read the freeze frame data for B0097 to confirm the sensor circuit is flagged.
  2. Visually inspect the right side restraint sensor, its mounting hardware, and the associated wiring harness for damage, corrosion, or loose connections.
  3. Perform a continuity and resistance test on the sensor circuit according to the service manual specifications.
  4. Apply voltage to the sensor connector and measure the sensor output signal while moving the seat belt or simulating occupant presence to verify proper operation.
  5. If the sensor and wiring test within spec, re‑flash or update the airbag control module software; if the fault persists, consider module replacement as a last resort.

Frequently asked

Can I fix B0097 by simply resetting the code?

Clearing the code without addressing the underlying issue will usually cause the code to return, and the airbag warning lamp will stay on.

Do I need to replace the entire airbag control module for this code?

Replacing the airbag control module is rarely necessary for B0097. The majority of cases are due to a faulty sensor, connector, or wiring. The module should be considered only after those components have been verified as good.

Will driving with the airbag warning lamp on affect vehicle safety?

Yes. The right‑side side curtain airbag may not deploy in a crash if the sensor fault is not repaired, reducing occupant protection on that side.

Is the sensor a replace‑once‑only part?

The sensor is a replaceable component. If testing shows it is out of specification, replace it and re‑test the circuit.
