B007F medium Severity

B007F: Passenger Seatbelt Pretensioner C Deployment Control (Subfault)

May not directly affect engine performance but impacts occupant safety systems (airbag/pretensioner).

Overview

Diagnostic Trouble Code B007F indicates a fault in the passenger seatbelt pretensioner C deployment control loop, often related to sensor or wiring issues within the occupant restraint system.

Common Symptoms

  • Airbag or safety restraint warning light illuminated
  • Seatbelt warning indicator active
  • Possible incorrect passenger occupancy detection

Most Common Causes

Faulty passenger seatbelt pretensioner component medium

Pretensioner loop may have resistance outside spec due to internal fault or wear. Commonly d as primary cause for B007F triggers. ([OBD2 Codes](https://obd2-codes.co/codes/b007f/?utm_source=chatgpt.com)

Seatbelt pretensioner circuit open or short medium

Wiring harness affected by chafing, break, corrosion leading to open/short circuit faults in deployment loop. ([OBD2 Codes](https://obd2-codes.co/codes/b007f/?utm_source=chatgpt.com)

Poor electrical connection medium

Loose terminals or connector corrosion in the restraint system harness. ([OBD2 Codes](https://obd2-codes.co/codes/b007f/?utm_source=chatgpt.com)

Faulty Restraints Control Module (RCM) or occupant classification system low

Module interpreting the pretensioner loop may fail; less common according to community consensus. ([OBD2 Codes](https://obd2-codes.co/codes/b007f/?utm_source=chatgpt.com)

Diagnostic Steps

  1. Retrieve all stored codes with a compatible OBD2 scanner supporting body/airbag codes.
    Expected: B007F present and possibly related airbag/seatbelt codes.
    Interpretation: Confirms current fault and detects any simultaneous faults. ([RepairPal.com](https://repairpal.com/obd-ii-code-b007f-passenger-seatbelt-pretensioner-c-deployment-control-subfault?utm_source=chatgpt.com)
  2. Perform a visual inspection of seatbelt pretensioner, wiring harness, and connectors in passenger seat area.
    Expected: No obvious damage, frayed wiring, or disconnected connectors.
    Interpretation: If damage found, likely cause is wiring/connection fault. ([GeekOBD](https://www.geekobd.com/dtc-codes/b007f.html?utm_source=chatgpt.com)
  3. Measure loop resistance of seatbelt pretensioner circuit per manufacturer spec using multimeter.
    Expected: Resistance within threshold specified by OEM.
    Interpretation: Out-of-spec resistance indicates pretensioner or wiring fault. ([OBD2 Codes](https://obd2-codes.co/codes/b007f/?utm_source=chatgpt.com)
  4. Test/scan occupant classification system sensors and restraints control module.
    Expected: No classification system sensor faults present.
    Interpretation: Faulty sensors or module may require replacement or programming. ([GeekOBD](https://www.geekobd.com/dtc-codes/b007f.html?utm_source=chatgpt.com)

Repair Solutions

Repair/replace wiring harness or connectors medium
Estimated Cost: $50 - $200

Fix damaged wiring or secure connectors to restore proper circuit continuity. ([OBD2 Codes](https://obd2-codes.co/codes/b007f/?utm_source=chatgpt.com)

Replace passenger seatbelt pretensioner hard
Estimated Cost: $150 - $300

Pretensioner replacement often requires airbag system recalibration. ([OBD2 Codes](https://obd2-codes.co/codes/b007f/?utm_source=chatgpt.com)

Replace/repair restraints control module or occupant classification sensor hard
Estimated Cost: $300 - $700

Module replacement often expensive and requires professional programming. ([GeekOBD](https://www.geekobd.com/dtc-codes/b007f.html?utm_source=chatgpt.com)

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Confusing airbag light generic fault with engine power issues
  • Assuming battery disconnection clears safety codes (unsafe and incorrect)
