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
Electrical issues in harness/connectors to passenger seatbelt load limiter can trigger this code.
Internal failure in the load limiter unit may cause improper signals to SRS control module.
Less common but possible if module fails to interpret sensor circuit correctly.
Moisture or corrosion affecting connector contacts could create intermittent open circuits.
Diagnostic Steps
-
Use a professional SRS-capable OBD2 scanner to retrieve stored and active codesExpected: Presence of B0082 and any associated SRS codesInterpretation: Confirms SRS system fault and isolates related faults
-
Visually inspect harness and connectors at passenger seatbelt load limiter and sensorExpected: No broken wires, loose pins, or corrosionInterpretation: Interruption in continuity suggests wiring/connector issue
-
Measure circuit resistance/continuity of seatbelt load limiter harness with multimeterExpected: Resistance within manufacturer specificationInterpretation: Abnormal values indicate open/short circuit
-
Swap or replace passenger seatbelt load limiter assembly if wiring checks normalExpected: Code clears after replacementInterpretation: Fault located in load limiter component
-
If issue persists, inspect SRS control module and perform software/firmware checkExpected: Module fault codes or update availableInterpretation: Confirms module-level issue
Repair Solutions
Cost depends on extent of harness damage and labor
Part costs vary widely by vehicle make/model
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
