Frequently Asked Questions

Can water bottles under the seat cause this?

Potentially. A leaking water bottle or drink container under the passenger seat could allow moisture to reach the seat harness connector, causing a short circuit.

Is this code related to the side curtain airbag?

No. B0022 specifically refers to the side torso airbag in the passenger seat, not the side curtain airbag in the headliner.

How do I prevent this from happening again?

Avoid storing items under the seats that could damage or wet the wiring. During car cleaning, be careful not to soak the area around seat connectors.
