B0082 high Severity

B0082: Passenger Seatbelt Load Limiter Deployment Control (Subfault)

May not affect engine drivability but disables or impairs passenger safety restraint system

Overview

B0082 indicates a malfunction in the passenger seatbelt load limiter deployment control circuit/sensor affecting SRS/passive restraint safety system.

Common Symptoms

  • Airbag/SRS warning light illuminated
  • Seatbelt warning light illuminated or fault
  • Possible loss of passenger restraint system functionality

Most Common Causes

Damaged or open/short circuit in load limiter/seatbelt sensor wiring medium

Electrical issues in harness/connectors to passenger seatbelt load limiter can trigger this code.

Faulty passenger seatbelt load limiter or pretensioner assembly medium

Internal failure in the load limiter unit may cause improper signals to SRS control module.

Faulty SRS/airbag control module low

Less common but possible if module fails to interpret sensor circuit correctly.

Corroded/poor electrical connectors at seatbelt SRS components low

Moisture or corrosion affecting connector contacts could create intermittent open circuits.

Diagnostic Steps

  1. Use a professional SRS-capable OBD2 scanner to retrieve stored and active codes
    Expected: Presence of B0082 and any associated SRS codes
    Interpretation: Confirms SRS system fault and isolates related faults
  2. Visually inspect harness and connectors at passenger seatbelt load limiter and sensor
    Expected: No broken wires, loose pins, or corrosion
    Interpretation: Interruption in continuity suggests wiring/connector issue
  3. Measure circuit resistance/continuity of seatbelt load limiter harness with multimeter
    Expected: Resistance within manufacturer specification
    Interpretation: Abnormal values indicate open/short circuit
  4. Swap or replace passenger seatbelt load limiter assembly if wiring checks normal
    Expected: Code clears after replacement
    Interpretation: Fault located in load limiter component
  5. If issue persists, inspect SRS control module and perform software/firmware check
    Expected: Module fault codes or update available
    Interpretation: Confirms module-level issue

Repair Solutions

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

Cost depends on extent of harness damage and labor

Replace passenger seatbelt load limiter/pretensioner assembly medium
Estimated Cost: $200 - $800

Part costs vary widely by vehicle make/model

Service or replace SRS control module hard
Estimated Cost: $500 - $1500

High cost typically at dealer level; may require programming

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Generic airbag code assumption without specific SRS subsystem check
  • Misinterpreting as seatbelt retractor failure rather than load limiter circuit

Frequently Asked Questions
