What Does B0082 Mean?
This code indicates the Body Control Module (BCM) or Restraint Control Module has detected a malfunction in the passenger seatbelt load limiter deployment circuit or control system. The load limiter is designed to release measured amounts of seatbelt webbing during a collision to reduce chest injuries. The subfault designation suggests a secondary or related issue within the load limiter deployment control system, such as a circuit resistance problem, internal component failure, or communication error.
Safety Warning
Vehicle should not be driven until repaired as the passenger seatbelt load limiter may not deploy properly in a collision, significantly increasing injury risk to the front passenger. The entire restraint system integrity is compromised and airbag warning light will remain illuminated.
Common Causes
45%
Faulty seatbelt pretensioner/load limiter assembly with internal circuit failure or damaged pyrotechnic charge connector
30%
Damaged or corroded wiring harness between restraint control module and passenger seatbelt load limiter
15%
Faulty Restraint Control Module (RCM) with internal deployment control circuit malfunction
10%
Previous deployment event not properly cleared or seatbelt buckle switch providing incorrect occupancy data
Diagnostic Steps
1
Step 1: Perform visual inspection of passenger seatbelt pretensioner assembly and connector at B-pillar for physical damage, corrosion, or signs of previous deployment (twisted webbing, blown charge indicators). Check for collision history in vehicle records.
2
Step 2: Using a digital multimeter, measure resistance across the load limiter deployment circuit at the pretensioner connector (typically 2-4 ohms when not deployed). Compare readings to manufacturer specifications and check for open or short circuits.
3
Step 3: Inspect wiring harness from B-pillar to restraint control module location for pinched wires, damaged insulation, water intrusion, or connector corrosion. Pay special attention to areas where harness passes through body panels or hinges.
4
Step 4: Using scan tool, monitor live data for passenger occupancy classification, seatbelt buckle status, and load limiter circuit voltage while moving seatbelt and connector. Look for intermittent dropouts or incorrect values.
5
Step 5: If all wiring and connections test good, perform resistance test on restraint control module deployment output circuit per manufacturer specifications to verify module integrity.
6
Step 6: After repairs, clear codes, perform restraint system self-test using scan tool, and verify airbag warning light extinguishes. Conduct test drive and re-scan to confirm no code recurrence.

The most common cause of B0082 (Passenger Seatbelt Load Limiter Deployment Control (Subfault)) is: Faulty seatbelt pretensioner/load limiter assembly with internal circuit failure or damaged pyrotechnic charge connector
Typical repair costs for B0082 range from $400 to $1,800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle should not be driven until repaired as the passenger seatbelt load limiter may not deploy properly in a collision, significantly increasing injury risk to the front passenger. The entire restraint system integrity is compromised and airbag warning light will remain illuminated.
