B00E1 medium Severity

B00E1: Third Row Right Seatbelt Pretensioner 'B' Deployment Control (Subfault)

Likely no direct drivability impact; relates to safety restraint system and may illuminate warning lights.

Overview

OBD‑II code B00E1 indicates a fault in the third row right seatbelt pretensioner 'B' deployment control circuit or sensor, triggering a body safety restraint fault.

Common Symptoms

  • Airbag/SRS warning light illuminated
  • Seatbelt warning light for third row right seat occupant
  • Fault code stored in BCM/SRS module

Most Common Causes

Faulty third row right seatbelt pretensioner assembly medium

Internal pretensioner failure or burned‑out squib may trigger this code.

Open or short in pretensioner wiring harness medium

Wiring issues between the pretensioner connector and airbag control module common in seatbelt circuits.

Poor electrical connector contact medium

Loose or corroded connector at pretensioner or BCM can cause intermittent deployment control fault.

Diagnostic Steps

  1. Verify code present and note freeze frame data with scan tool
    Expected: Code B00E1 stored with relevant module flags
    Interpretation: Confirms B00E1 as active or historic in body/SRS module.
  2. Visually inspect third row right seatbelt pretensioner harness and connector
    Expected: No broken wires, corrosion, or loose pins
    Interpretation: Wiring or connector integrity issues can cause subfault.
  3. Measure continuity and resistance of pretensioner squib circuit
    Expected: Resistance within manufacturer spec (typically low ohm value)
    Interpretation: High resistance/open indicates wiring/pretensioner fault; short indicates possible short or module issue.
  4. Reconnect or repair wiring; if needed replace pretensioner
    Expected: Code clears after repair and does not return
    Interpretation: Confirms cause isolated to seatbelt pretensioner circuit.

Repair Solutions

Repair or replace third row right seatbelt pretensioner and associated wiring medium
Estimated Cost: $200 - $800

Costs depend on part pricing and labor; safety system parts often higher cost.

Clean and secure electrical connectors at pretensioner and BCM/SRS unit easy
Estimated Cost: $0 - $50

Simple reconnection or cleaning can resolve intermittent contact issues.

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Assuming general SRS/airbag malfunction without isolating specific pretensioner circuit
