HUMMER B — Body

Passenger Deploy. Loop Resistance High

Brand: HUMMER
Type: B — Body
Views: UK: 7 EN: 15 RU: 9
AI status
Completed
ready
Completed 100%
Page language: EN

Causes

  • Open or corroded connector in passenger deployment circuit
  • Damaged or chafed wiring harness to the passenger airbag
  • Poor or intermittent connector pin contact at the airbag or SRS module
  • Faulty passenger airbag (inflator/squib) with internal high resistance
  • Aftermarket seat heaters or accessories interfering with the loop
  • Moisture or corrosion in a connector or wiring splice

Symptoms

  • Airbag / SRS warning lamp illuminated on instrument panel
  • Passenger airbag status (ON/OFF) may be incorrect or disabled
  • Possible loss of passenger airbag deployment readiness
  • Vehicle stores B1015 in SRS memory
  • Some vehicles may disable seat-belt pretensioner(s) or passenger airbag

What to check

  • Read and record SRS codes and freeze-frame data with a capable scan tool
  • Check instrument cluster for airbag lamp behavior and passenger airbag indicator
  • Visually inspect passenger seat area, underside of seat, and B-pillar for damaged wiring or connectors
  • Inspect passenger airbag connector (under dash or seat) for corrosion, bent pins, or loose mating
  • Perform continuity/resistance checks of the passenger squib circuit using an ohmmeter (see safety steps)
  • Wiggle test harness while monitoring live SRS data for intermittent changes

Signal parameters

  • Passenger deployment loop resistance (ohms) — expected low; fault if above OEM threshold
  • Squib circuit continuity — open/short status
  • Circuit voltage present at connector (should be no deployment voltage when system disabled)
  • SRS lamp status (on/off) and related SRS module readiness flags
  • Presence/occupancy sensor state (may affect passenger airbag status)

Diagnostic algorithm

  1. Read and record all SRS-related trouble codes and freeze-frame data using an OEM-capable scan tool.
  2. Follow safe SRS procedures before probing the system: disable the battery and wait the manufacturer-specified time for capacitors to discharge (commonly 2–10 minutes) and wear appropriate personal protective equipment. Never measure squib resistance with system armed or with deployment voltage applied.
  3. Visually inspect the passenger airbag connector(s), wiring harness, and seat area for physical damage, corrosion, pin push-out, or signs of water ingress.
  4. Reconnect battery only when safe per OEM procedures to use live-data features. Use scan tool to view passenger squib circuit live values while performing non-invasive tests.
  5. With the system safely disabled and per OEM instructions, measure resistance across the passenger airbag squib terminals at the connector near the airbag module and at the SRS control module harness to localize the high-resistance point.
  6. If high resistance is localized to a connector, repair or replace the connector and clean corroded terminals; if wiring is damaged, repair with correct procedures (splice/replacement and insulation).
  7. If wiring and connectors test good and resistance remains high, replace the passenger airbag module only using OEM parts and following all safety and handling procedures.
  8. After repairs, clear codes, perform a system self-test with a scan tool, and verify lamp extinguishes and no new codes return. If intermittent faults persist, perform a detailed wiring diagram trace and consult OEM service information or escalate to a specialized SRS technician.
  9. Document all steps, parts, and measurements. If the SRS control module is suspected, verify other SRS circuits and consult OEM diagnostic flow before replacing the module.

Likely causes

  • Corroded or loose connector at passenger airbag or floor harness
  • Wiring damage under the passenger seat due to seat movement
  • Internal failure or increased resistance in the passenger airbag squib
  • Connector pin pushed out or bent at seat/airbag connector

Fault status

⚠️ Status
Passenger airbag deployment loop resistance above allowed threshold — SRS fault; passenger airbag may be disabled until repaired.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 1-3 hours
