B0007 DTC Code: Passenger Frontal Airbag Stage 1 Deployment Control Fault

The B0007 Diagnostic Trouble Code (DTC) indicates a malfunction in the passenger frontal airbag Stage 1 deployment control circuit. This Body (B) code is related to the Supplemental Restraint System (SRS). When the SRS control module detects an electrical fault in the Stage 1 deployment circuit, it stores code B0007 and turns on the airbag warning light.

What Does Code B0007 Mean?

B0007 means the SRS control module has detected an abnormal electrical condition in the passenger frontal airbag Stage 1 deployment circuit. Dual-stage airbag systems use two separate deployment circuits to control inflation force. If the Stage 1 circuit experiences an open circuit, short circuit, or abnormal resistance, the control module disables the affected airbag function and stores DTC B0007.

Symptoms of B0007

• Airbag (SRS) warning light illuminated.
• SRS warning message displayed.
• Passenger frontal airbag Stage 1 may be disabled.
• Additional SRS trouble codes may be stored.

Common Causes

• Faulty passenger dual-stage airbag module.
• Damaged wiring harness.
• Loose or corroded electrical connectors.
• Open circuit or short circuit in the deployment circuit.
• Faulty SRS control module.
• Collision damage or previous improper repairs.

How to Diagnose B0007

1. Read all stored SRS fault codes using a professional scan tool.
2. Inspect the passenger airbag wiring and connectors.
3. Check for damaged insulation, corrosion, or loose terminals.
4. Follow the manufacturer's diagnostic procedures for the deployment circuit.
5. Repair the fault, clear the code, and verify the repair.

Possible Repairs

• Repair damaged wiring.
• Replace faulty connectors.
• Replace the passenger airbag module if defective.
• Repair or replace the SRS control module if required.
• Clear the diagnostic code after repairs.

Can You Drive with B0007?

Although the vehicle will usually remain drivable, it is not recommended to ignore this code because the passenger airbag may not provide full protection during a collision.

Estimated Repair Cost

Repair	Estimated Cost (USD)
Wiring repair	$50–$200
Connector replacement	$20–$80
Passenger airbag replacement	$300–$1,200
SRS control module replacement	$300–$1,000

Frequently Asked Questions

What is Stage 1 airbag deployment?

Stage 1 is the initial deployment level of a dual-stage airbag system, typically used during moderate-impact collisions to reduce injury risk while providing effective protection.

Can B0007 clear itself?

No. If the electrical fault remains, the code will continue to return until the problem is repaired.

Will the passenger airbag still work?

Depending on the vehicle design, the passenger frontal airbag or its Stage 1 deployment function may be disabled until the fault is corrected.

Conclusion

The B0007 DTC indicates an electrical fault in the passenger frontal airbag Stage 1 deployment circuit. Repairing the issue promptly helps restore full SRS functionality and ensures maximum passenger protection in the event of an accident.
