B0010 — Front Passenger Frontal Stage 1 Deployment Control
B0010 points to the front passenger frontal airbag stage 1 deployment loop, the first-stage squib circuit in the dash-mounted passenger airbag. The restraint control module saw circuit resistance or voltage outside its limits, meaning an open, a short or high resistance. The failure-type byte gives the exact condition, and the meaning can vary by manufacturer.
What this means for truckers
Stop within ~50 miles on a Cummins X15, Detroit DD15, PACCAR MX-13. Driving longer risks damaging adjacent components (turbo housing, head gasket, aftertreatment) and turning a $300 fix into a $3,000 fix.
Before you replace parts — try this first
B0010 is an airbag (SRS) circuit code, most often loose or corroded passenger airbag connector behind the dash. Airbag circuits are not treated like ordinary sensors:
- Treat the airbag as possibly disabled. With an SRS code set, the airbag may not deploy in a crash. Get it diagnosed soon.
- Disconnect the battery and wait before touching anything. Follow the service manual wait time (often 1–10 minutes) so the SRS module reserve power drains.
- Never probe a squib circuit with a test light or ohmmeter. Use the manufacturer's SRS simulator/load tool and a scan tool that reads SRS codes.
- Check the cheap items first. Seat and clockspring connectors under the seat or behind the wheel are common causes after seat or steering work.
- Replace parts only after diagnosis. Some modules must be replaced, not reset, after a deployment.
Symptoms
The airbag lamp stays on and the passenger airbag may be disabled. A passenger airbag status indicator, if fitted, may look wrong. The truck otherwise drives normally. The code often shows up after dash work, a radio, ELD or gauge install, or water getting in under the dash.
