B00E5 medium Severity

B00E5: Second Row Center Seatbelt Pretensioner C Deployment Control (Subfault) — fault in deployment control circuit for second‑row center seatbelt pretensioner “C”.

Typically does not affect engine operation but may cause airbag/safety restraint warning light and disable safety belt pretensioner function.

Overview

B00E5 OBD‑II body code second row center seatbelt pretensioner C deployment control subfault wiring or pretensioner issue

Common Symptoms

  • Restraint system warning light or airbag warning light ON
  • Seatbelt pretensioner circuit fault indicated on scan tool

Most Common Causes

Faulty second row center seatbelt pretensioner C medium

Pretensioner itself may have internal failure or open/short conditions.

Open or short in seatbelt pretensioner ‘C’ harness or connector medium

Wiring harness connectors often cause intermittent faults when loose or corroded.

Poor electrical connection at seatbelt pretensioner or control module medium

Loose, corroded, or damaged terminals can disrupt proper signal.

Diagnostic Steps

  1. Connect professional scan tool and verify B00E5 presence with freeze frame data.
    Expected: Confirmed presence of code B00E5 in memory and associated freeze frame values.
    Interpretation: Ensures correct code and conditions exist before further diagnosis.
  2. Visually inspect second row center seatbelt pretensioner wiring harness and connectors for damage or corrosion.
    Expected: No damaged wires, secure connectors with no corrosion; if present corrective action required.
    Interpretation: Wiring/connectors often the cause; visible issues increase likelihood of harness fault.
  3. Measure resistance of pretensioner circuit per OEM specification with multimeter (ignition OFF).
    Expected: Circuit resistance within specification; no open or short.
    Interpretation: Out‑of‑range resistance indicates pretensioner or wiring fault; guide part replacement or repair.
  4. If wiring and resistance are correct, evaluate airbag/pretensioner control module diagnostics.
    Expected: Control module communicates correctly; no other related faults.
    Interpretation: Control module internal fault may be cause if other components verified good.
