What it means
B009F is the generic code for a fault in the right side restraints sensor 6 circuit or device. The restraint control unit (airbag module) saw a signal, communication or electrical value from this sensor that was missing or outside its expected range. The sensor's exact type and position, such as a side impact accelerometer or pressure sensor, depend on the vehicle, so check the model-specific wiring information.
Symptoms
- Airbag or SRS warning light on the dashboard
- Warning message about a restraint system fault on some vehicles
- Passenger or right side airbags may be disabled by the system
- Intermittent warning light that comes and goes with bumps or door movement
- Other restraint codes stored alongside it, such as for the right side airbag or other sensors
Possible causes
- Damaged, corroded or loose connector at the right side restraint sensorlikely
- Wiring fault (open circuit, short or chafing) between the sensor and the restraint control unit, often in the door, sill or seat arealikely
- Faulty right side restraint sensorpossible
- Previous accident or repair that left the sensor damaged, wrongly fitted or not mounted securelypossible
- Low battery voltage or poor earth causing the control unit to log a sensor faultpossible
- Faulty restraint control unit or outdated software, where the manufacturer has documented it for the modelrare
How to diagnose
- Read all stored and pending codes and any freeze frame data, and note whether B009F is current or historic and whether other restraint codes are present.
- Check the battery condition and charging voltage, as low voltage can set restraint faults.
- Find the right side sensor 6 location from model-specific information, and visually inspect the sensor, its mounting and the surrounding body for crash or repair damage.
- Inspect the sensor connector and the wiring along its route for corrosion, bent or pushed-back pins, chafing and water ingress, with the battery disconnected and the correct waiting time observed before touching any restraint connector.
- Do not probe airbag circuits with a standard test meter. Use the manufacturer's procedure for any resistance or voltage checks.
- Clear the code and see whether it returns. Gently move the wiring and connector while monitoring live data, if the system supports it, to find an intermittent fault.
- If the wiring and connectors are good, compare sensor live data with the specification for the model and check the sensor is secure and correctly oriented.
- Check for software updates or technical bulletins for the model before considering the control unit as faulty.
How to fix
- Clean, repair or replace a damaged or corroded connector and terminals.
- Repair or replace damaged wiring between the sensor and the restraint control unit, using the correct method for airbag wiring.
- Replace the faulty right side restraint sensor and make sure it is mounted correctly and torqued to specification.
- Correct any crash damage or poor repair around the sensor mounting, then verify the system.
- Rectify battery or earth problems, then clear the code and confirm it does not return.
- Update the control unit software or replace the unit only if confirmed as the cause, then carry out any required setup procedures.

High severity
The car can be moved carefully to a workshop, but the right side restraint protection may not work properly in a crash. Avoid using it for anything other than getting it repaired, and have it fixed promptly.
