Deployment Commanded w/Loop Malfunction

Causes

  • Open or short in airbag/squib wiring harness
  • Poor or corroded connector at airbag module or airbag/pretensioner
  • Faulty airbag squib or pretensioner (internal short/open)
  • Damaged clock spring (steering column) affecting driver airbag squib circuit
  • Water intrusion or physical damage to wiring
  • Faulty SRS/airbag control module or internal driver for the squib circuit

Symptoms

  • SRS/Airbag warning lamp illuminated on dash
  • Possible stored crash/impact event data
  • Certain airbags or pretensioners disabled (reduced protection)
  • Related restraint system faults present in scan tool data
  • Possible intermittent lamp or multiple SRS DTCs

What to check

  • Scan SRS/airbag control module for all stored codes and freeze-frame/crash data
  • Verify battery voltage and charging system are within specification
  • Visually inspect connectors, airbag module plugs, and visible wiring for damage or corrosion
  • Inspect steering column/clock spring if driver airbag is involved
  • Check harness routing for pinch points, chafing, or water entry
  • Measure squib circuit resistance and continuity with ignition OFF and battery disconnected

Signal parameters

  • Squib circuit continuity: expect low ohms (manufacturer spec; typical squib resistance is low single-digit ohms)
  • Open circuit = infinite resistance; short to voltage or ground = near 0 ohms or unexpected continuity to battery/ground
  • Deployment command = high-current pulse at battery voltage (only seen with safe test equipment or manufacturer diagnostic procedures)
  • No deployment command should be issued while service connector is disconnected and during resistance checks

Diagnostic algorithm

  1. Retrieve and record all SRS codes and freeze-frame/crash data using a capable scan tool. Do NOT attempt repairs before reading stored data.
  2. Verify system voltage and health (battery fully charged, connections clean). Low voltage can cause false SRS faults.
  3. Visually inspect the entire related harness, connectors, and airbag modules for damage, corrosion, or signs of a previous deployment.
  4. With ignition OFF and battery negative disconnected (follow manufacturer recommended disconnect interval — typically wait at least 2 minutes), measure squib circuit resistance between airbag connector and SRS module pins. Compare to service spec. Look for open, high resistance, or short to ground/voltage.
  5. Inspect and test the clock spring if driver airbag circuit is affected. Replace if intermittent/open/short present.
  6. Repair any damaged wiring or connectors (replace terminals, pins, or harness as required). Use only manufacturer-approved replacement airbag connectors and wiring repair procedures.
  7. If wiring and connectors are good, swap or bench-test (per manufacturer procedures) suspect airbag/pretensioner components only if authorized and using proper safety fixtures — otherwise replace the airbag/pretensioner assembly.
  8. If harness and components check OK, consider SRS control module fault. Confirm with manufacturer diagnostics before module replacement; modules may require programming or crash data clearing by authorized service.
  9. After repairs, clear codes and perform SRS system self-checks. Verify no new faults and confirm SRS indicator behaves normally.
  10. If crash data is present, follow manufacturer policy: many modules are non-repairable after deployment/crash and must be replaced and reprogrammed.

Likely causes

  • Open or high-resistance connection in the squib/deployment loop
  • Short to ground or short to voltage on the deployment circuit
  • Connector corrosion or disconnected connector at the airbag or module
  • Damaged wiring harness from impact or wear
  • Failed airbag/pretensioner squib element

Fault status

⚠️ Status
SRS deployment commanded but deployment loop/squib circuit malfunction detected — deployment inhibited or not verified.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 1.0-3.5 hours
