Causes

Open or short in the inflatable seat belt squib/wiring
Corroded or loose connector at the seat belt module or airbag control module
Faulty inflatable seat belt module (squib/pyrotechnic device or control unit)
Poor or missing ground/power to the seat belt deployment circuit
Previous deployment — damaged/removed components not replaced correctly
SRS control module internal fault or software/communication error

Symptoms

SRS/airbag warning lamp illuminated on instrument cluster
Possible disablement of inflatable seat belt deployment for second-row left seating position
Stored trouble code(s) and inability to clear without repair
Possible related occupant restraint system diagnostics flagged (reduced protection)

What to check

Scan SRS/airbag control module to confirm DTC B00F2 and check for related codes or freeze frame data
Visual inspection of the second-row left seat belt, connectors, and wiring for damage, corrosion, or loose connectors
Verify whether the vehicle has had a prior deployment and that replacement parts were fitted correctly
Check power and ground at the seat belt module connector with key off and per manufacturer safety procedures
Measure continuity and resistance of the squib circuit from connector to airbag control module (do not attempt to fire or energize the squib)

Signal parameters

Typical squib/inflator resistance: low ohms (commonly ~0.5–2.0 ohms) — manufacturer-specific values vary
Open circuit: infinite/OL resistance; short to ground: near 0 ohms
Vehicle battery/ignition voltage should be stable ~12V during checks
SRS control module reports status via diagnostic bus (CAN) — communication should be normal
No firing voltage should be present during diagnosis; do NOT attempt to apply power to the squib

Diagnostic algorithm

Read and record all SRS/airbag codes and freeze frame data with a capable scan tool. Note any additional codes.
Follow vehicle manufacturer safety procedures for SRS work: key off, disconnect battery and wait the specified time before handling SRS components.
Visually inspect the second-row left inflatable seat belt assembly, connector, and harness routing for physical damage, corrosion, or signs of repair.
Inspect connector pins for corrosion, bent pins, or foreign material; reconnect securely and check for retention.
With battery disconnected and per manufacturer guidance, measure resistance/continuity of the squib circuit from the seat belt inflator connector to the SRS control module. Compare to manufacturer spec. Look for open or high-resistance conditions.
Check power and ground circuits to the seat belt module (with proper safety precautions and tools). Verify wiring integrity and absence of short to chassis.
If wiring and connectors are good but resistance is out of spec, replace the inflatable seat belt module/inflator assembly (do not attempt to reuse a deployed inflator).
If wiring is damaged, repair to manufacturer standards (splice methods, insulation, routing) and recheck continuity/resistance.
After repairs, reconnect battery, clear codes, and perform SRS system checks with a scan tool to confirm the fault does not return and system readiness is restored.
If fault persists and wiring and module check good, consider SRS control module inspection or reprogramming per manufacturer procedures.

Likely causes

Damaged harness or chafed wiring in the second-row left seatbelt circuit
Corroded/loose connector at the seat belt inflator/module
Open or high-resistance squib (inflator) or connector (most common)
Faulty seat belt inflator/module requiring replacement

Fault status

⚠️ Status

Stored when the SRS control module detects a malfunction in the deployment control circuit for the second-row left inflatable seat belt (electrical fault, open/short, module fault, or circuit problem). The SRS warning light is likely illuminated and inflatable seat belt deployment for that seating position may be disabled until repaired.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 1.0-3.0 hours
