B007D: Second Row Center Seatbelt Pretensioner B Deployment Control (Subfault)

May not directly impact engine drivability but can disable or compromise seatbelt pretensioner safety systems.

Overview

B007D refers to a body/safety restraint system code indicating a fault in the second row center seatbelt pretensioner B deployment control circuit.

Common Symptoms

  • Airbag or supplemental restraint system (SRS) warning light illuminated
  • Seatbelt pretensioner system indicator or warning
  • Possible diagnostic codes present for related seatbelt or airbag modules

Most Common Causes

Faulty second row center seatbelt pretensioner module medium

Pretensioner itself may have failed or internal short.

Wiring harness open/short or poor connection in pretensioner circuit medium

Corroded, damaged, or loose connectors under seats often trigger body safety codes.

Faulty airbag control module interpretation low

Control module processing or software anomaly could falsely register B007D without hardware fault.

Diagnostic Steps

  1. Obtain full SRS code readout with OEM-level scanner.
    Expected: Diagnostic trouble code B007D with possible related codes.
    Interpretation: Confirms seatbelt pretensioner B deployment control fault.
  2. Visually inspect wiring and connectors for second row center seatbelt pretensioner.
    Expected: Check for broken wires, corrosion, loose clips.
    Interpretation: Damaged connections likely root cause if present.
  3. Measure resistance and voltage in pretensioner circuit per OEM specs.
    Expected: Resistance/voltage within specified range.
    Interpretation: Abnormal values indicate sensor or wiring fault.
  4. If wiring checks good, replace second row center pretensioner module.
    Expected: Post-replacement code clear and no symptom recurrence.
    Interpretation: Confirms module failure.

Repair Solutions

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

Depends on extent of wiring damage and labor involved.

Replace second row center seatbelt pretensioner assembly medium
Estimated Cost: $200 - $500

Requires SRS reset and potentially seat disassembly.

Reprogram or update SRS/airbag control module hard
Estimated Cost: $100 - $300

Only if supported by OEM technical service bulletin or specific symptoms.

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Assuming generic airbag sensor fault without isolating seatbelt pretensioner circuit
