Passenger Frontal Stage 1 Deployment Control
Fault in the passenger frontal airbag deployment loop. Same safety-critical handling as B0001, on the passenger side.

你会注意到的故障现象
- Airbag lamp on
- Passenger airbag disabled indicator
- No audible difference
常见原因
按可能性从高到低排列——从最上面开始查。
- 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
如何排查
先做花钱最少、侵入最小的检查——大多数这类码不是零件问题。
- ✓ 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.
维修方案
- Repair the wiring or connector
- Replace the airbag assembly if deployed or damaged
- Replace the control module only as a last step
B0010 —— 常见问题
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.
