B0024 high Severity

B0024: Left Front/Driver Frontal Deployment Loop (Single Stage or Stage 1) Short to Ground or Voltage Out of Range

Airbag warning light illuminated; driver frontal airbag may fail to deploy properly, compromising occupant safety

Overview

B0024 driver frontal airbag deployment loop voltage out of range short to ground airbag circuit fault

Common Symptoms

  • Airbag warning light ON
  • Driver frontal airbag disabled or non‑functional

Most Common Causes

Damaged or shorted wiring harness in the driver frontal airbag deployment loop high

Short to ground/out‑of‑range voltage usually indicates wiring harness or connector fault

Faulty steering wheel module coil/clockspring medium

Clockspring provides electrical connection through steering column and is a common failure point

Poor electrical connection or corrosion at connectors medium

Loose or corroded connectors can lead to intermittent voltage errors

Faulty airbag control module (ACM/SDM) low

Malfunctioning module may misinterpret signals or provide incorrect voltage

Diagnostic Steps

  1. Perform a full airbag system scan with professional scan tool
    Expected: Retrieve B0024 and check for related SRS codes
    Interpretation: Confirms code is present and helps identify additional related faults
  2. Visually inspect wiring harness and connectors for damage, chafing, corrosion, or loose pins
    Expected: No physical damage or corrosion
    Interpretation: If damage is present, repair or replace harness/connectors
  3. Test continuity and resistance of deployment loop wiring and clockspring with multimeter
    Expected: Resistance within manufacturer specification
    Interpretation: Out‑of‑range resistance indicates open/short circuit
  4. Measure voltage at relevant airbag circuit points during ignition ON
    Expected: Voltage within expected range
    Interpretation: Voltage out of range confirms circuit issue
  5. If wiring and connectors are good, consult airbag control module diagnostics
    Expected: No erratic or incorrect signals reported
    Interpretation: Irregular signals suggest ACM/SDM fault
