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.

    • The code B1615 on a Toyota, related to the SRS (Supplemental Restraint System), typically indicates an issue with the passenger airbag sensor or a malfunction in the occupant classification system. Here’s what it may mean and some steps to troubleshoot it:

      Cause of Code B1615

      1. Passenger Occupant Classification Sensor: This sensor detects whether a passenger is present and how the airbag should deploy. If it’s faulty or misaligned, it could trigger this code.
      2. Faulty Wiring or Connector: Damaged or loose connectors in the seat wiring harness, often located under the passenger seat, can cause a bad connection with the SRS system.
      3. Faulty Airbag Module: In rare cases, the airbag control module itself could have an internal failure.
      4. Seat Position Sensor Malfunction: A misaligned or faulty seat position sensor can also trigger this code.

      Repair Steps

      1. Inspect Wiring and Connectors: Check for loose or damaged connectors, especially under the passenger seat. Reseat or replace as necessary.
      2. Examine the Occupant Classification System: Make sure the seat sensor is properly calibrated and functioning. Recalibration might be needed, which can often be done with a scanner or by a professional.
      3. Reset the Airbag System: After repairs, clear the code with a scanner and see if it returns.
      4. Check Airbag Module: If the issue persists, consider testing or replacing the airbag module, but this step is usually the last resort.

      If you're unable to clear the code after checking these areas, a visit to a technician or dealer may be necessary, as specialized tools and expertise are often required for SRS system repairs.
