What it means
The restraint control module detected a fault in the driver knee airbag deployment control circuit. The airbag may not deploy as intended in a crash.
How it works
The driver knee airbag is a low-mounted restraint intended to help protect the driver’s lower body, and the restraint control module monitors its deployment circuit. B0014 sets when that module detects a fault in the driver knee airbag circuit, which may prevent the airbag from deploying as designed.
Common causes
Most likely first.
- Squib circuit open or shorted
- Airbag connector loose
Symptoms
- Airbag warning light on
How to diagnose it
- Read SRS freeze-frame and subfault information with a capable scan tool to identify the driver knee airbag circuit condition.
- Follow the manufacturer’s SRS safeing procedure, then inspect the driver knee airbag connector and wiring for looseness, corrosion, or physical damage.
- Check the circuit for an open, short, or poor terminal contact using the manufacturer’s specified SRS test method.
- If the connector and harness pass, test the driver knee airbag module and restraint control module following the service information.
- After repair, clear B0014 and rescan to confirm the driver knee airbag fault has not returned.
Common fixes
- Reconnect or repair the loose driver knee airbag connector using the specified SRS procedure.
- Repair damaged wiring or terminals in the driver knee airbag circuit.
- Replace the driver knee airbag module if it fails its specified circuit test.
- Repair or replace the restraint control module if diagnostics confirm it is faulty.
Can I keep driving?
The warning light means the driver knee airbag may not deploy in a crash, reducing lower-body restraint protection. Minimize driving until the fault is repaired, and do not probe the airbag circuit with standard test equipment.
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.
