B007E medium Severity

B007E: Driver Seatbelt Pretensioner C Deployment Control (Subfault)

May illuminate airbag/safety warning light; does not typically affect engine performance but indicates a safety restraint system fault.

Overview

B007E diagnostic trouble code driver seatbelt pretensioner C deployment control subfault body code seat belt airbag safety restraint

Common Symptoms

  • Airbag or safety restraint warning light illuminated
  • Stored B007E on scan tool
  • Possible safety belt pretensioner fault indication

Most Common Causes

Faulty driver seatbelt pretensioner C module medium

Internal failure of the airbag seatbelt pretensioner component.

Wiring harness open/short or poor electrical connection medium

Resistance out of range in deployment loop can trigger the code.

Restraints Control Module (RCM) malfunction low

Control module error or internal software/communication fault.

Diagnostic Steps

  1. Connect diagnostic scan tool and verify B007E present
    Expected: B007E code stored in body control/airbag module
    Interpretation: Confirms code presence before proceeding
  2. Inspect wiring harness and connectors for driver seatbelt pretensioner C circuit
    Expected: No open, short, corrosion or damage
    Interpretation: Wiring integrity essential; faults may cause erroneous resistance readings
  3. Measure deployment loop resistance per manufacturer spec
    Expected: Resistance within specified range
    Interpretation: Out-of-range resistance indicates wiring or component defect
  4. Test or replace driver seatbelt pretensioner C component if wiring is good
    Expected: Fault disappears when pretensioner replaced
    Interpretation: Confirms pretensioner module was cause

Repair Solutions

Repair or replace damaged wiring/connectors medium
Estimated Cost: $100 - $400

Cost depends on extent of wiring repair and labor rates

Replace driver seatbelt pretensioner C assembly hard
Estimated Cost: $300 - $800

Part cost varies by make/model; safety system work should be done by trained technician

Reprogram or replace Restraints Control Module if faulty hard
Estimated Cost: $500 - $1200

Often requires dealership-level tools

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Assuming a generic body code unrelated to the seatbelt pretensioner circuitry
