B0010 B0xxx · Body (B) High severity
Passenger Frontal Stage 1 Deployment Control
Fault in the passenger frontal airbag deployment loop. Same safety-critical handling as B0001, on the passenger side.
Severity guidance: High — stop driving and diagnose now; risk of further damage
Symptoms you will notice
- Airbag lamp on
- Passenger airbag disabled indicator
- No audible difference
Common causes
Ordered from most to least likely — start at the top.
- 1 Open squib circuit or high resistance
- 2 Damaged wiring in the dash harness
- 3 Faulty connector at the airbag
- 4 Previously deployed or tampered airbag
How to diagnose it
Cheapest and least invasive first — most of these codes are not a parts problem.
- ✓ Follow the full airbag safety procedure before testing.
- ✓ Read loop resistance from the airbag ECU.
- ✓ Inspect the passenger-side dash harness and connector.
- ✓ Verify no aftermarket work has disturbed the wiring behind the glovebox.
Repair options
- Repair the wiring or connector
- Replace the airbag assembly if deployed or damaged
- Replace the control module only as a last step
B0010 — frequently asked questions
Why does it come back after clearing? +
Airbag codes latch and often require a specific reset procedure after the physical fault is fixed.
Does the passenger seat sensor matter here? +
That is a different code (B0080). B0010 is strictly about the deployment loop.
