B00E8 high Severity

B00E8: Third Row Center Seatbelt Pretensioner C Deployment Control (Subfault)

May not directly affect engine drivability but affects occupant safety restraint system

Overview

B00E8 code refers to an invalid or fault condition in the third row center seatbelt pretensioner C deployment control circuit indicating potential issues with the seatbelt pretensioner/airbag safety system.

Common Symptoms

  • Airbag / SRS warning light illuminated
  • Safety restraint system fault displayed in diagnostic tool

Most Common Causes

Faulty third row center seatbelt pretensioner C module medium

Seatbelt pretensioner component itself may have failed or degraded

Open or shorted pretensioner wiring harness medium

Circuit issues often trigger invalid data fault

Poor electrical connection or corrosion in pretensioner circuit medium

Connector issues may cause sporadic faults

Airbag / occupant detection system module communication error low

Body control or airbag control module could misreport or misinterpret data

Diagnostic Steps

  1. Connect professional diagnostic scanner to obtain live data and freeze frame data
    Expected: Retrieve B00E8 stored and any associated codes showing related circuits
    Interpretation: Confirm B00E8 presence and check if other restraint system codes exist
  2. Inspect third row center seatbelt pretensioner wiring harness and connectors
    Expected: Check for open/short, corrosion, or damage
    Interpretation: Bad wiring supports electrical cause
  3. Measure circuit resistance of pretensioner squib and compare to specification
    Expected: Proper resistance indicative of intact squib
    Interpretation: Out of range resistance suggests pretensioner or wiring fault
  4. Check BCM and airbag / occupant detection module communication and history
    Expected: No communication errors
    Interpretation: Communication faults can trigger invalid data errors

Repair Solutions

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

Cost varies by vehicle accessibility and harness complexity

Replace third row center seatbelt pretensioner assembly hard
Estimated Cost: $200 - $800

Part prices vary by make/model; safety-critical component

Reprogram or reset airbag/BCM modules if needed medium
Estimated Cost: $100 - $250

May require dealer-level tools

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Assuming generic OBD-II engine or transmission fault due to misinterpretation of code letter B
