B00E0 medium Severity

B00E0: Third Row Left Seatbelt Pretensioner B Deployment Control (Subfault)

May not directly impact engine drivability but affects Supplemental Restraint System (SRS) safety readiness; airbag or seatbelt warning light likely illuminated.

Overview

OBD-II B00E0 code relates to a deployment control subfault for the third row left seatbelt pretensioner 'B' in the vehicle's body restraint system.

Common Symptoms

  • Airbag or SRS warning light illuminated
  • Seatbelt pretensioner readiness fault detected by BCM/SRS module
  • Possible disabled pretensioner function

Most Common Causes

Faulty third row left seatbelt pretensioner 'B' component medium

Pretensioner internal fault or failure to meet factory specifications can trigger this code.

Open or short wiring or harness for the pretensioner circuit medium

Poor electrical connection between pretensioner and SRS control module may set the code.

Poor electrical connection at pretensioner connector or body control module medium

Corrosion, loose connectors, or grounding issues can cause intermittent faults.

Diagnostic Steps

  1. Record freeze frame and confirm B00E0 presence with a capable SRS/OBD-II scan tool.
    Expected: B00E0 displayed with related SRS events and possibly airbag light history.
    Interpretation: Confirms the fault is currently or recently active in the seatbelt pretensioner circuit.
  2. Visually inspect wiring harness and connectors for the third row left seatbelt pretensioner.
    Expected: No damaged, corroded, or disconnected wiring; secure connector.
    Interpretation: If damaged harness or connector issues found, repair or reconnect as needed.
  3. Measure pretensioner circuit resistance and continuity with manufacturer-specific data.
    Expected: Resistance within OEM spec and continuity present.
    Interpretation: Out-of-spec resistance suggests pretensioner or wiring harness issue.
  4. Check for related SRS codes or multiple seatbelt restraint codes.
    Expected: No other SRS subfault codes beyond seatbelt third row left.
    Interpretation: Presence of network or BCM faults suggests broader control module issues.
