Causes

Open or shorted wiring in driver inflatable seat belt squib/deployment circuit
Corroded or loose connector at the seat, seatbelt inflator, or SRS/airbag control module
Failed seatbelt inflator/squib or internal short in inflator
Faulty SRS (airbag) control module or deployment control unit
Intermittent connection caused by seat track movement or harness chafing
Stored crash-related data or previous deployment not cleared properly

Symptoms

SRS/airbag warning lamp illuminated on instrument cluster
Possible supplemental restraint system message on dash or instrument display
Driver inflatable seat belt function disabled (may not deploy in a crash)
Stored SRS related fault codes and freeze-frame data in airbag module
In some cases, loss of communications with seat/airbag control module

What to check

Read and record all SRS/airbag fault codes and freeze-frame data with a capable scan tool
Note lamp status and any related SRS or occupant classification codes
Visually inspect connectors at the driver seat, seatbelt inflator, and airbag control module for corrosion, deformation, or loose pins
Inspect wiring along the seat harness and under-seat areas for chafing, breaks, or damage (pay attention to seat track areas)
Check battery voltage and SRS module power/ground integrity before testing
Do not probe squib connector while system is armed; follow SRS safety procedures (disconnect battery and wait specified time)

Signal parameters

Inflator/squib circuit continuity: low resistance when intact (manufacturer-specific; typically low ohms)
Open-circuit/OL indicates an open or disconnected inflator/squib
Short to ground or short to battery (very low resistance to 0 Ω or to 12V) indicates a wiring short or internal inflator failure
Module communication: CAN/diagnostic comms present and error-free when scanned
Stored freeze-frame: vehicle speed, battery voltage, and time at fault occurrence (from scan tool)

Diagnostic algorithm

Safety first: follow manufacturer SRS safety procedures—disable SRS power, disconnect battery, and wait recommended time before inspecting or disconnecting airbag/squib connectors
Scan for codes: use a qualified scan tool to record B00F0 and any related SRS/CAN codes and freeze-frame data
Check power/ground: with battery connected and using safe procedures, verify SRS module supply voltage and ground integrity per vehicle spec
Visual inspection: with battery disconnected, inspect connectors, harness, and inflator for damage, corrosion, or loose pins; focus on under-seat routing and seat track pinch points
Harness continuity/resistance: measure resistance of the driver inflatable seat belt squib circuit between module connector and inflator connector. Compare to manufacturer spec; open or very high resistance = broken/open circuit; very low or near-zero may indicate short
Wiggle test: with a technician observing live data (if supported) or monitoring resistance, move the seat through adjustment range to reproduce intermittent faults caused by wire chafing
Connector repair: repair or replace damaged terminals, harness sections, or connector shells. Use correct SRS-rated repair methods (crimp, solder and seal per manufacturer guidance)
Inflator replacement: if wiring and connector integrity confirmed but resistance indicates internal inflator fault, replace the driver inflatable seat belt assembly or inflator module per OEM procedure
Module/communication faults: if wiring and inflator check good but fault persists, investigate SRS control module functionality and communications (bus errors, lost comms) and consider module replacement or reprogramming as required
Clear codes and verify: after repairs, reconnect battery, clear codes, perform SRS system self-test, and confirm no reoccurrence of B00F0 and that SRS lamp behavior is normal

Likely causes

Open/infinite resistance in inflator/squib circuit due to damaged harness or connector
Low/high resistance in the squib (internal short or degraded element)
Connector corrosion at seatbelt inflator or airbag module
Seat wiring pinched/damaged by seat adjustment or service work
Faulty SRS control module or data/communication error

Fault status

⚠️ Status

Driver inflatable seat belt deployment control fault detected — circuit, connector, inflator or SRS module issue present; SRS/airbag warning lamp likely illuminated.
