B0010 — Passenger Frontal Stage 1 Deployment Control

Generic OBD-II · all makesBody

Code B0010 indicates a malfunction in the deployment control circuit for the passenger-side frontal stage 1 airbag. This typically means the Airbag Control Module has detected an electrical irregularity, such as high resistance or an open circuit, in the deployment squib or its associated wiring.

Symptoms

What causes it — most likely first

1. Faulty Airbag Module

Internal failure of the stage 1 deployment squib within the passenger airbag assembly.

2. Wiring Harness Damage

Frayed, pinched, or broken wires leading to the passenger airbag connector.

3. Corroded or Loose Connector

Poor electrical contact at the airbag module connector due to moisture, corrosion, or improper seating.

4. Grounding Issue

A poor ground connection in the passenger-side electrical subsystem affecting the SRS circuit.

5. Airbag Control Module Failure

Internal hardware failure within the SRS/Airbag Control Module (ACM).

How it's diagnosed

  1. Confirm the presence of the SRS warning light and scan for all active B-codes.
  2. Visually inspect the passenger airbag connector for security and signs of corrosion.
  3. Inspect the wiring harness for physical damage, such as chafing or rodent damage.
  4. Perform a continuity test on the wiring from the control module to the airbag connector using a low-current diagnostic tool.
  5. Verify the integrity of the system grounds associated with the SRS circuit.

Frequently asked

Can I use a standard multimeter to test the airbag?

No. Using a standard multimeter to test an airbag squib can send enough current to accidentally trigger the airbag deployment.

Is the Airbag Control Module (ACM) usually the cause of B0010?

No. It is far more common for the fault to lie within the airbag module itself or the wiring harness than in the control module.

Is the car safe to drive with this code?

The vehicle remains drivable, but the passenger frontal airbag may not function in an accident, significantly increasing the risk of injury.
