Detailed Description of Error B0087

OBDII error code B0087 is a manufacturer-specific code that refers to a problem with the Third Row Center Seatbelt Load Limiter Deployment Control (Subfault). This code is usually associated with vehicles that have advanced safety features, including seatbelt pretensioners and load limiters. The load limiter is designed to reduce the force of the seatbelt on the occupant''s body during a crash, helping to prevent injuries. The deployment control module is responsible for controlling the load limiter''s operation.

When the onboard computer (OBDII) detects a fault in the deployment control module or the load limiter itself, it will trigger the B0087 error code. This code is usually displayed on the vehicle''s dashboard or instrument cluster, along with the ''Service Airbag System'' or ''Airbag System Fault'' warning light.

The B0087 error code can be caused by a variety of factors, including electrical issues, faulty sensors, or problems with the deployment control module. In some cases, the code may be triggered by a minor issue, but it can also indicate a more serious problem that requires immediate attention.

Possible Causes of Error B0087

  • Short circuit or open circuit in the load limiter wiring
  • Corrosion or damage to the load limiter connector
  • Deployment control module failure
  • Seatbelt pretensioner failure
  • Seatbelt load limiter failure
  • Electrical issue with the airbag system
  • Software issue with the OBDII system
  • Seatbelt sensor failure
  • Incorrect seatbelt installation or maintenance

Possible Fixes for Error B0087
