B0010 — Passenger Frontal Airbag Stage 1 Deployment Control Circuit Fault

Severity: high Drive with care, to a shop

What B0010 means

The SRS control module continuously monitors the stage 1 squib circuit of the front passenger airbag for correct resistance, opens, and shorts to ground or voltage. B0010 is stored when the circuit falls outside the allowed range. The airbag may not deploy in a crash, so the module turns on the SRS warning light.

Symptoms

  • SRS (airbag) warning light is on or flashing
  • B0010 stored in the SRS module
  • Passenger front airbag may not deploy in a crash
  • Passenger airbag off indicator is on or flashing
  • Scan tool shows a squib circuit fault

Possible causes

  1. Open or shorted wiring in the passenger airbag deployment circuit
  2. Corroded, loose, or damaged SRS connectors
  3. Faulty passenger airbag module (squib)
  4. Damaged clockspring, if it is part of the circuit
  5. Failed SRS control module or its driver circuit
  6. Occupant classification system or dash wiring problems

How to diagnose

  1. Scan all modules with an SRS-capable tool, record the data, and look for other SRS codes
  2. Inspect connectors under the dash, at the SRS module, and under the passenger seat for moisture, corrosion, or poor latching
  3. Find out whether the dash, seat, or airbag was recently serviced or removed
  4. Disconnect the battery and wait the time the manufacturer specifies, then test the circuit wiring for opens and shorts
  5. Measure the circuit only with the manufacturer-approved method and tools; never apply power to a squib
  6. Check the clockspring and seat occupancy sensor if they are in the circuit
  7. After repair, clear the code and confirm it stays away and the SRS light goes out

Common fixes

  • Repair or replace damaged wiring and connectors in the airbag circuit
  • Replace the passenger airbag module
  • Replace the clockspring if it is faulty
  • Replace or repair the SRS control module
  • Clean contacts and restore secure connector latching

Questions and answers

What does code B0010 mean?

The SRS module detected a fault in the stage 1 deployment circuit of the front passenger airbag. It is most often a wiring, connector, or airbag module problem.

Can I drive with B0010?

Technically yes, but the passenger airbag may not deploy in an accident. Get it diagnosed soon and avoid seating anyone up front.

Can I test the airbag circuit myself?

Only read codes and visually inspect connectors. Measuring the squib circuit or removing the airbag risks accidental deployment and is best left to a professional.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
