What Does B0010 Mean?
This code indicates a malfunction in the passenger frontal airbag deployment control circuit, specifically the first stage of deployment. The Airbag Control Module (ACM) has detected an electrical fault or abnormal resistance in the passenger airbag squib circuit, wiring harness, or control module itself. This subfault designation suggests a partial or intermittent fault condition that prevents proper airbag deployment capability.
Safety Warning
Vehicle is unsafe to drive as the passenger airbag will not deploy in a collision, creating serious injury risk for front-seat passengers. This requires immediate professional diagnosis and repair; the SRS warning light will remain illuminated indicating system malfunction.
Common Causes
35%
Damaged wiring harness or corroded connectors in passenger airbag circuit between ACM and airbag inflator
30%
Faulty passenger airbag inflator or squib with open/short circuit or out-of-spec resistance
20%
Defective Airbag Control Module with internal circuit failure or software corruption
10%
Low battery voltage or poor ground connection affecting ACM operation and circuit testing
5%
Previous airbag deployment or accident damage not properly repaired with system components not reset
Diagnostic Steps
1
Step 1: Perform visual inspection of passenger airbag wiring harness and connectors for visible damage, corrosion, or loose connections. Check dash area, under-seat connectors, and ACM connections for physical damage or water intrusion
2
Step 2: Using a digital multimeter with airbag-safe test leads, measure resistance across passenger airbag squib terminals (ACM disconnected). Normal reading should be 2-3 ohms; readings outside manufacturer specification indicate faulty inflator
3
Step 3: Check continuity and resistance of wiring harness from ACM connector to passenger airbag connector on both circuits. Any reading above 5 ohms or infinite resistance indicates wiring fault
4
Step 4: Measure battery voltage at ACM power supply pin (should be 12-14V) and verify proper ground connection with voltage drop test (should be less than 0.1V drop to chassis ground)
5
Step 5: If all wiring and components test within specification, perform ACM diagnostic self-test using advanced scan tool functions to check for internal module faults or stored crash data requiring module replacement
6
Step 6: After repairs, clear codes, perform drive cycle, and verify airbag light remains off. Confirm system operation with scan tool live data showing proper circuit resistance and readiness status

The most common cause of B0010 (Passenger Frontal Stage 1 Deployment Control (Subfault)) is: Damaged wiring harness or corroded connectors in passenger airbag circuit between ACM and airbag inflator
Typical repair costs for B0010 range from $300 to $1,800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
