B00B6 medium Severity

B00B6: Driver Seat Recline Position Restraints Sensor (Subfault)

The vehicle may show a body/electronic warning and potentially related airbag/SRS warnings, but normal driving is generally not immediately compromised.

Overview

Diagnostic Trouble Code B00B6 refers to a fault in the driver seat recline position restraints sensor, often triggering an airbag/SRS warning due to a seat position sensor fault.

Common Symptoms

  • Airbag or SRS warning light illuminated on dashboard
  • Fault code stored in body control module concerning seat recline position sensor
  • Seat memory or seat electronic adjustments not functioning as expected

Most Common Causes

Faulty driver seat recline position restraints sensor medium

Sensor itself may have failed or degraded electrical characteristics.

Open or shorted wiring harness to seat recline position sensor medium

Wiring issues are a common root cause where physical damage or connector corrosion is present.

Poor electrical connection at sensor connector medium

Loose or corroded pins can cause abnormal readings to the control module.

Faulty airbag control module misinterpreting sensor signal low

Less common but possible if module electronics are failing or mis-calibrated.

Diagnostic Steps

  1. Verify DTC with a professional scan tool and note any related SRS/airbag codes.
    Expected: B00B6 stored in seat/airbag system control module.
    Interpretation: Confirms the presence of the B00B6 code and that it relates to the recline position sensor.
  2. Inspect the seat recline position sensor wiring and connector for damage or corrosion.
    Expected: Wiring intact, no corrosion, secure connectors.
    Interpretation: Good wiring reduces likelihood of wiring harness as cause; damage may pinpoint root issue.
  3. Measure sensor signal and reference voltage with a multimeter per OEM spec.
    Expected: Reference voltage present and sensor returns expected signal range.
    Interpretation: Deviation suggests sensor failure or short/open condition.
  4. Swap or replace recline position sensor if available and re-test.
    Expected: Code no longer returns if sensor was replaced successfully.
    Interpretation: If code clears and does not return, the original sensor was likely faulty.

Repair Solutions

Estimated Cost: $150 - $500

Cost varies by vehicle model and accessibility.

Repair wiring harness or connectors to sensor medium
Estimated Cost: $50 - $300

Depends on extent of wiring repair needed.

Reprogram or calibrate airbag control module after repair hard
Estimated Cost: $100 - $400

May require dealer-level tooling.

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Assuming airbag control module failure without checking seat sensor wiring and signal
