Code B1B0A Description

The B1B0A diagnostic trouble code (DTC) indicates that there is an open circuit in the Passenger Airbag Squib 1 circuit. The airbag squib is a component of the airbag system that is responsible for deploying the passenger side airbag in the event of a collision. An open circuit means that there is a break or interruption in the electrical pathway, preventing the airbag from deploying properly.

Symptoms of B1B0A

  1. Airbag warning light illuminated on the dashboard
  2. Passenger airbag indicator shows a fault
  3. Loss of communication with the airbag system
  4. Inability to pass state inspection due to airbag system fault

How to Fix B1B0A

  1. Begin by conducting a thorough inspection of the wiring harness and connectors to identify any visible damage or breaks. Repair or replace any damaged components as needed.
  2. Test the passenger airbag squib for proper functionality using a multimeter. Replace the squib if it fails the test.
  3. Check and replace any blown fuses in the airbag system to ensure proper electrical flow.
  4. If the issue persists, consult with a professional technician to diagnose any underlying problems with the airbag control module and address them accordingly.

Cost to Fix B1B0A

The cost of repairing a Passenger Airbag Squib 1 Circuit Open can vary depending on the specific cause of the issue and the extent of the repairs needed. In general, the cost of replacing a faulty airbag squib can range from $200 to $600, while repairing a damaged wiring harness may cost between $100 and $300. Additional costs for diagnostic testing, labor, and any necessary replacement parts should be factored into the overall repair estimate.

When is the Code Detected?

This Diagnostic Trouble Code (DTC) sets when the ORC detects a open or high resistance on the squib circuit for more than 2.5 seconds. This DTC transitions from active to stored when the ORC sees a recovery from the open or high resistance condition for greater than 2.5 seconds.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

  • Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
  • Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
  • Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
  • Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
