B009F — Right Side Restraints Sensor 6 Fault

Severity: medium Safe to drive

What B009F means

The airbag (SRS) control module constantly polls its crash sensors and checks their circuits. B009F means right side restraints sensor 6 is not responding correctly or its circuit shows a fault. It is a subfault code, so the exact detail depends on the manufacturer. While the fault is active, part of the protection on that side may be disabled.

Symptoms

  • Airbag/SRS warning light on
  • Light stays on after engine start
  • Possible airbag system fault message
  • Other SRS codes may be stored

Possible causes

  1. Damaged or corroded wiring or connectors at the right side sensor
  2. Faulty side crash sensor 6
  3. Poor connection at a connector under the seat or in the body pillar after repairs
  4. Faulty airbag control module
  5. Prior collision or bodywork with incorrect sensor installation

How to diagnose

  1. Scan all SRS codes with a scan tool that supports airbags and note whether the fault is current or stored
  2. Inspect right side connectors and harness for corrosion, damage or moisture
  3. Confirm the sensor is mounted correctly, secure and shows no impact damage
  4. Test circuit resistance and continuity following the manufacturer wiring diagram
  5. Check power and ground at the sensor and the connector condition
  6. Swap in a known good sensor or replace it and see if the fault clears
  7. If sensor and wiring are good, test the SRS module

Common fixes

  • Repair the wiring and connectors to the right side sensor
  • Replace sensor 6 following the manufacturer procedure
  • Replace or reprogram the SRS control module
  • Clear codes and confirm the warning light goes out

Questions and answers

Can I drive with code B009F?

The car will run, but the right side protection may not work in a crash. Get it fixed as soon as you can.

Why is my airbag light on?

The SRS module found a fault in the circuit of right side sensor 6 and is warning that the system may not work properly.

Can I work on SRS sensors myself?

Visually checking connectors is fine, but turn the ignition off and disconnect the battery as the service manual says. Leave sensor replacement to a professional.

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.
