What it means
B0010 flags an electrical fault in the passenger (RF) frontal airbag, Stage-1 deployment loop. Depending on the OEM and sub-byte, it may indicate open/high resistance, low resistance (short), or voltage out-of-range on the airbag high/low control circuits. Factory procedures group B0010 with tests that isolate the passenger airbag module, wiring/connectors, and the RCM/SDM. Charm+2Charm+2
Symptoms
- SRS/Airbag lamp on; B0010 stored.
- Passenger airbag inhibited until repaired/cleared. Charm
Severity / priority
High (safety-critical). A deployment-loop fault can lead to improper or non-deployment in a crash. Address immediately. Charm
Common causes
- Open/high resistance from broken/chafed wiring, poor terminal tension, or connector corrosion.
- Low resistance / short-to-ground or short-to-battery in the loop.
- Damaged clock spring/spiral cable where routing passes the column (platform-dependent).
- Less common: failed passenger airbag module or RCM/SDM. Charm+1
Diagnostic notes
- Use an SRS-capable scan tool to confirm B0010 and note any symptom-byte (e.g., :01 short to B+, :02 short to GND, :04 open, :0D high resistance, :0E low resistance). Follow OEM SRS safety (battery disconnect & wait; do not probe live inflator circuits). Charm
- Perform visual inspection of the IP/airbag connectors, intermediate connectors, and column/under-dash harness; look for pin fit and corrosion/water intrusion.
- With the inflator disconnected per OEM, measure loop/segment resistance and check for short-to-GND/B+ per the pinpoint tests. Charm+1
Possible fixes
- Repair wiring/terminals; correct routing/strain relief; clean or replace corroded connectors.
- Replace a failed clock spring if indicated by continuity tests.
- Replace the passenger airbag module only if it fails OEM checks; evaluate RCM/SDM last.
- Clear DTCs, cycle ignition, and verify with a re-scan. Charm
