B0082: Passenger Seatbelt Load Limiter Deployment Control (Subfault)

What it means

This code identifies a fault associated with the passenger seat belt load limiter deployment control. The restraint control module sets it when it detects a problem in that deployment control; the exact fault is specified by accompanying subfault information.

How it works

The passenger seatbelt load limiter is part of the SRS belt system and is intended to manage belt force on the passenger during a crash. The restraints control module monitors its deployment circuit and sets this code when it detects a fault; accompanying subfault information specifies the failure type.

Common causes

Most likely first.

1. Load limiter wiring or connector fault
2. Open or shorted deployment circuit
3. Faulty passenger seat belt load limiter
4. Restraint control module fault

Symptoms

• Airbag warning light on
• Passenger load limiter may not operate in a crash

How to diagnose it

1. Read the SRS subfault details and freeze-frame data to establish the reported circuit condition and when it occurred.
2. Inspect the passenger load limiter connector and harness for damage, corrosion, poor connection, or pinching near the belt assembly.
3. Check for related SRS codes that could indicate a shared module power, ground, or connector issue.
4. Make the SRS safe according to the manufacturer's procedure, then test the passenger load limiter circuit for the open or short indicated by the subfault.
5. If wiring checks pass, test the passenger load limiter and restraints control module with the manufacturer's diagnostic procedure.

Common fixes

• Reconnect or repair a loose or corroded passenger load limiter connector.
• Repair damaged wiring or an open or short in the passenger load limiter circuit.
• Replace the passenger seatbelt load limiter assembly if it fails the specified checks.
• Repair or replace the restraints control module if testing confirms an internal fault.

Can I keep driving?

The vehicle may be driveable, but the passenger load limiter may not manage belt force as intended in a crash. Keep the passenger properly restrained and arrange prompt SRS diagnosis; avoid probing deployment wiring outside the manufacturer's safety procedure.
