B0014: Air bag deployment circuit or seat wiring fault
What Does B0014 Mean?
B0014 is a high-signal diagnostic/code reference associated with air bag deployment circuit or seat wiring fault. FixIt matched it to 11 NHTSA owner reports across 6 vehicle models; the strongest signal is Chevrolet Malibu.
This page was promoted from the June 2026 ranked content-gap batch because owner-report demand is concentrated enough to deserve a full diagnostic guide. GM owner reports most often mention service-airbag warnings and wiring/sensor faults under the seat. Treat the code as a diagnostic direction, then confirm the exact manufacturer definition, companion codes, and live data before replacing expensive parts.
Symptoms of B0014
- ⚠️ Service Air Bag message or SRS warning light
- ⚠️ Airbag module stores B0014 with other deployment-loop codes
- ⚠️ Warning changes when seat position or under-seat wiring moves
- ⚠️ Airbags may be disabled while the fault is active
Common Causes
- 🔍 Broken or high-resistance wiring under the seat
- 🔍 Loose SRS connector or damaged terminal tension
- 🔍 Failed seat/side airbag sensor or deployment loop component
- 🔍 Previous repair that disturbed SRS harness routing

Diagnostic Tips
- Do not probe SRS circuits casually; follow the service manual and disable power first
- Inspect under-seat harness routing, connectors, and terminal condition
- Scan the SRS module for companion B-codes before replacing parts
- Repair wiring/connectors and clear codes only after confirming circuit resistance is in spec
Common Mistakes to Avoid
- ❌ Replacing a module or safety component before checking power, ground, connectors, and companion codes.
- ❌ Using only a generic OBD-II scanner when the code is stored in ABS, SRS, body, or manufacturer-specific modules.
- ❌ Clearing the code before saving freeze-frame data and confirming whether recalls/campaigns apply.
