What it means
The right rear side impact sensor is reporting a malfunction or implausible signal.
How it works
Right side restraints sensor 2 is identified as a rear side-impact sensor and reports crash-related information to the restraint control module. B0097 indicates that this sensor is reporting a malfunction or implausible input; the precise failure mode depends on the vehicle's SRS diagnostics.
Common causes
Most likely first.
- Sensor failure
- Corroded sensor connector
Symptoms
- Warning light or symbol related to the affected system
- Comfort or safety function impaired
How to diagnose it
- Read the SRS module with a compatible scan tool, confirm B0097, and note whether the fault is current or stored with event data.
- Use service information to identify the right rear sensor 2 location and inspect its mounting area for damage or movement.
- Following the vehicle's SRS disable procedure, inspect the sensor connector for corrosion, looseness, damaged pins, or moisture.
- Check the accessible wiring from right rear sensor 2 for rubbing, breaks, or poor connections, then test the circuit using the manufacturer's procedure.
- If the circuit is sound, test the sensor's reported signal and module connection as directed by the manufacturer.
Common fixes
- Reconnect and secure the right rear sensor 2 connector.
- Repair corroded terminals or damaged wiring in its circuit.
- Correct any damaged or loose sensor mounting.
- Replace the sensor if it fails the manufacturer's diagnostic test.
Can I keep driving?
The affected side-impact protection may not operate as intended in a collision. Limit driving to what is necessary until the SRS fault is diagnosed, and avoid handling the sensor or its wiring without the prescribed safety steps.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
