B0014: Airbag Deployment Loop Circuit Fault

Airbag system may be disabled and fail to deploy in a collision

Overview

B0014 indicates an airbag deployment loop circuit fault in the supplemental restraint system (SRS), often related to resistance issue, open/short circuit or wiring/connectors around the side or frontal airbag deployment loop

Common Symptoms

  • Airbag warning light illuminated
  • Airbag system disabled
  • Intermittent airbag light
  • No additional symptoms until collision

Most Common Causes

Damaged or chafed wiring in airbag deployment loop high

Commonly causes open or short to ground/voltage in the loop

Poor electrical connection or corroded connector high

Connectors under seat or in loop harness often loose or corroded

Faulty airbag module or impact sensor medium

Module failure or sensor fault can report incorrect loop status

Seatbelt pretensioner harness mispositioned or pinched medium

May cause intermittent contact affecting loop continuity

Diagnostic Steps

  1. Verify and note any additional SRS codes with scan tool
    Expected: B0014 with or without related loop codes
    Interpretation: Confirms the deployment loop fault requires further investigation
  2. Visually inspect airbag wiring harness and connectors (under seats, seat belt area)
    Expected: Look for damaged, pinched, corroded or disconnected wiring
    Interpretation: Damage or poor connection often the root cause
  3. Measure resistance and continuity of the deployment loop circuit with multimeter
    Expected: Resistance within manufacturer spec; no opens or shorts
    Interpretation: High/low resistance or open/short confirms wiring or component fault
  4. Check and reseat connectors, especially under driver/passenger seat
    Expected: Good fit, clean contacts
    Interpretation: Restores proper connection if previously loose or corroded
  5. If wiring and connectors OK, test or replace airbag module or impacted sensor
    Expected: Module reacts within spec on loop tests
    Interpretation: Faulty module may need replacement

Repair Solutions

Repair or replace damaged wiring harness medium
Estimated Cost: $100 - $600

Cost varies widely based on vehicle model and extent of damage

Clean and secure connectors or replace corroded clips easy
Estimated Cost: $20 - $120

Often resolves loose contact issues

Replace faulty airbag module or sensor hard
Estimated Cost: $400 - $1500

Airbag module replacement should follow OEM safety procedures

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Confusing B0014 with network communication codes or non‑SRS related electrical faults
