B0061 Airbag Diagnostic Trouble Code (DTC)
The B0061 Diagnostic Trouble Code (DTC) indicates a fault within the Supplemental Restraint System (SRS). On many vehicles, this code is associated with an impact sensor, side airbag circuit, or another airbag deployment component. Because manufacturers define B0061 differently, the exact meaning varies by make and model.
Typical Symptoms
Common Causes
- Faulty impact sensor.
- Damaged side airbag circuit.
- Loose or corroded electrical connector.
- Broken wiring harness.
- Clock spring failure (depending on vehicle).
- Fault inside the Airbag Control Module (ACM/RCM/SDM).

Diagnostic Steps
- Read all stored SRS fault codes.
- Inspect the impact sensor connector.
- Check wiring for damage or corrosion.
- Measure wiring continuity.
- Verify module power and ground.
- Repair the fault and clear the code.
- Confirm the warning light stays OFF.
Important Note
Never measure airbag squib circuits with a standard test light or connect power directly to any airbag component. Always follow the manufacturer's safety procedures before servicing the SRS system.

Frequently Asked Questions
Can I continue driving with B0061?
The vehicle may still drive normally, but the airbag system may not protect occupants properly during a collision.
Can a bad connector trigger B0061?
Yes. Loose, damaged, or corroded connectors are common causes.
Does B0061 always mean the impact sensor is defective?
No. Wiring, connectors, the control module, or other SRS components may also cause this code.
Note: The exact definition of B0061 depends on the vehicle manufacturer. Wiring colors, connector pinouts, resistance values, and circuit configuration may vary between different makes and models.
