B0044 high Severity

B0044: Left Front/Driver Frontal Deployment Loop Circuit Fault

Airbag system malfunction; potential non‑deployment of driver airbag in collision

Overview

DTC B0044 indicates a fault in the driver frontal deployment loop circuit of the airbag/supplemental restraint system, often due to electrical issues in the deployment loop, connectors, wiring, or modules.

Common Symptoms

  • Airbag warning light on
  • Supplemental Restraint System indicator illuminated
  • Possible disabled driver airbag deployment

Most Common Causes

Faulty airbag deployment loop wiring or connectors high

Corrosion, open or shorted wiring in the driver frontal deployment loop can trigger B0044.

Faulty airbag module or squib medium

Defective steering wheel airbag module or squib can cause low resistance in the loop.

Airbag control module fault medium

Internal SDM/ACM error may falsely report loop fault if module diagnostics are compromised.

Diagnostic Steps

  1. Retrieve DTC with professional scan tool and confirm code B0044
    Expected: B0044 present in memory
    Interpretation: Confirms fault stored by airbag control module
  2. Perform visual inspection of driver frontal deployment loop wiring and connectors
    Expected: No visible damage, corrosion, or loose connections
    Interpretation: Eliminates obvious wiring faults
  3. Measure loop resistance with multimeter per manufacturer spec
    Expected: Resistance within specified range
    Interpretation: Out‑of‑range indicates open/short in loop
  4. Test/replace airbag module or squib if wiring check is normal
    Expected: Circuit within resistance spec
    Interpretation: Confirms module or squib as root cause

Repair Solutions

Repair or replace damaged wiring/connectors in the deployment loop medium
Estimated Cost: $50 - $200

Cost depends on extent of wiring repair and labor.

Replace driver airbag module or squib medium
Estimated Cost: $150 - $300

Requires careful handling and reset of airbag system.

Airbag control module diagnostics and potential replacement hard
Estimated Cost: $300 - $600

High cost; recommended after confirming module failure.

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Misinterpreting generic ISO/SAE reserved claim as no fault
  • Diagnosing unrelated body electrical issues instead of deployment loop
