B0097 — Right Side Restraints Sensor 2 Fault

Severity: medium Safe to drive

What B0097 means

The supplemental restraint system (SRS) control module constantly monitors its sensors and circuits. B0097 means the signal from right side restraints sensor 2 is missing, out of range or not what the module expects. The exact sensor depends on the vehicle: it may be a side impact sensor, a passenger presence sensor or a related component. Once the fault is set, the module may disable some or all airbags.

Symptoms

  • Airbag (SRS) warning light is on
  • Passenger seat belt reminder or occupancy indicator acts incorrectly
  • SRS fault message on the dash
  • Passenger airbag off indicator behaves oddly

Possible causes

  1. Failed right side sensor (side impact or passenger presence sensor)
  2. Poor connection at the sensor connector, corroded terminals
  3. Broken, chafed or shorted wiring on the right side, including under the seat or in the pillar
  4. New sensor installed but not coded or recognized by the SRS module
  5. Internal fault in the SRS control module

How to diagnose

  1. Scan all modules with a tool that supports SRS, record freeze frame data and look for other related codes
  2. Inspect the right side sensor and its connector for damage, moisture and corrosion
  3. Check the harness under the right seat for pinching or wear, especially if the seat was moved or loaded
  4. Make sure nothing is stuck under the seat and connectors are fully latched
  5. Test sensor resistance and wiring continuity per the factory diagram, and check for shorts to ground or power
  6. Confirm battery voltage is normal
  7. Clear the code and see whether it returns immediately or only under certain conditions
  8. If a part was replaced, verify sensor coding or setup with the SRS module

Common fixes

  • Replace the faulty right side sensor
  • Repair the wiring or replace a damaged connector
  • Code or calibrate a new sensor to the SRS module
  • Reprogram or replace the SRS control module if it is confirmed faulty

Questions and answers

What does B0097 mean?

The SRS module detected a fault in right side restraints sensor 2. It is most often a passenger presence or side impact sensor, or its wiring.

Is it safe to drive with B0097?

You can drive, but the airbags may not deploy properly in a crash. Have it diagnosed as soon as you can.

Can I just clear the code?

You can, but if the cause is still there the code will return and the SRS light will come back on. Find and fix the fault first.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
