OBD-II code · ABS / Safety
B-codes cover airbags, climate, radios, and body electronics, and they are manufacturer-specific. Most point at a single sensor, switch, or connector — not the entire system they belong to.
Airbag-adjacent B-codes get scary: whole steering-wheel module, seat sensors, the works. Most are a single clockspring, connector, or seat-buckle switch.
Typical guess-and-swap cost: $1,000+ (steering-wheel module) for an $80 clockspring
SRS-safe diagnostics: exact manufacturer subcodes, resistance and data checks through the circuit with proper disarm procedures. A 20-minute scan-and-multimeter job — with the safety steps respected.
