Code B165A Scion Description
The B165A diagnostic trouble code for Scion vehicles indicates that the Occupant Detection Sensor Zero Point Calibration is incomplete. This sensor is a crucial component of the vehicle's occupant detection system, which is responsible for determining whether a passenger is present in the front passenger seat and adjusting the deployment of the airbag accordingly. When the zero point calibration is incomplete, the system may not function properly, potentially leading to incorrect airbag deployment or failure to deploy in the event of a collision.
Common Causes of B165A Scion
- Electrical issues such as a loose connection or damaged wiring affecting the occupant detection sensor.
- Faulty occupant detection sensor requiring replacement.
- Software glitch preventing the completion of the zero point calibration.
- Impact or physical damage to the occupant detection sensor.
- Issues with the vehicle's battery voltage affecting the calibration process.
Symptoms of B165A Scion
- Airbag warning light illuminated on the dashboard.
- Inconsistent or erratic airbag deployment.
- Passenger airbag indicator showing incorrect status.
- Fault codes related to the occupant detection system stored in the vehicle's computer.
- In some cases, the airbags may not deploy at all in a collision.
How to Fix B165A Scion
- Begin by checking the wiring and connections related to the occupant detection sensor for any damage or loose connections. Repair or replace as necessary.
- Perform a diagnostic scan to retrieve the fault codes and clear them from the vehicle's computer memory.
- Attempt to complete the zero point calibration using a diagnostic tool compatible with the vehicle's system.
- If the calibration cannot be completed, consider replacing the occupant detection sensor with a new, OEM part.
- After the repair is completed, perform a final diagnostic scan to ensure the fault codes have been cleared and the system is functioning properly.
Cost to Fix B165A Scion
The cost of repairing the Occupant Detection Sensor Zero Point Calibration Incomplete issue can vary depending on the specific cause of the problem and the labor rates in your area. In general, the cost of parts for this repair can range from $200 to $500, with labor costs adding an additional $100 to $200. Keep in mind that these are rough estimates, and actual costs may vary based on the vehicle make and model, as well as the location and rates of the auto repair shop. It's recommended to consult with a professional technician for a more accurate cost estimate tailored to your specific situation.

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.
