B00F2: Second Row Left Inflatable Seatbelt Deployment Control

May not directly affect drivability but indicates a fault in the supplemental restraint system (airbag/seatbelt safety system), potentially disabling safety functions.

Overview

B00F2 seatbelt deployment control fault second row left inflatable seatbelt safety system

Common Symptoms

  • Airbag or SRS warning light illuminated
  • Seatbelt pretensioner system fault
  • Possible disablement of second row left inflatable seatbelt deployment

Most Common Causes

Wiring harness short to battery voltage or ground medium

Generic wiring faults such as shorts or open circuits can trigger this reserved body code.

Faulty or damaged connector medium

Poor connection at seatbelt pretensioner or control module can cause intermittent faults.

Defective seatbelt pretensioner or SRS component low

Internal failure of the seatbelt deployment control component itself.

Control module internal error low

Fault within the body control or SRS module potentially due to software or hardware malfunction.

Diagnostic Steps

  1. Retrieve all related safety system codes with an advanced scanner capable of reading SRS/airbag codes.
    Expected: List of stored safety system related codes including B00F2.
    Interpretation: Establish if this fault is isolated or accompanied by other SRS/B‑series codes.
  2. Visually inspect wiring and connectors at second row left seatbelt pretensioner and related harnesses.
    Expected: No visible damage, corrosion, or pinched wiring.
    Interpretation: Damaged wiring/connectors may explain intermittent or continuous fault.
  3. Check continuity and resistance of seatbelt pretensioner deployment circuit.
    Expected: Circuit within manufacturer specification.
    Interpretation: Out‑of‑spec readings indicate wiring or component fault.
  4. Verify proper operation of body control/SRS module via diagnostic tool tests.
    Expected: Module communicates correctly and reports normal sensor input.
    Interpretation: Communication issues may indicate ECU fault requiring repair or reprogramming.

Repair Solutions

Repair or replace damaged wiring/connectors medium
Estimated Cost: $50 - $300

Cost depends on extent of wiring damage and labor; safety system work should follow precautions.

Replace seatbelt pretensioner assembly (second row left) hard
Estimated Cost: $200 - $800

Part cost varies by vehicle; must be done by qualified technician.

Reprogram or replace body control/SRS module hard
Estimated Cost: $300 - $1200

Module replacement and reprogramming often expensive and dealer‑level.

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Generic ISO/SAE reserved misinterpreted as specific component failure without proper SRS diagnostics
