Tesla Model S (2012-2025) Service Manual / Safety and Restraint / Sensor - Occupant Classification - Front Passenger's Seat - Calibration
Note: The OCS is not installed in all markets and is currently only present in North America. This OCS re-zero calibration procedure is for North America.
OCS Re-Zero Calibration
- Ensure that no objects are on or under the passenger seat. Warning: Performing this procedure with weight on the passenger seat could result in the passenger airbag not deploying as designed.
- Ensure that the passenger seat belt buckle is not latched.
- Run the "Occupant Classification System Re-Zero" procedure in Toolbox.
- Exit the vehicle. This turns off the driver rail and cycles the power on the vehicle.
- Sit in the driver's seat again. Step on the brake pedal to turn on the drive rail to cycle the power on the vehicle.
- Ensure that the airbag safety indicator light displays on the
instrument cluster during vehicle startup and then turns off after 5
seconds.

- Verify that the Occupant Classification status has changed to "EMPTY". If it does not, repeat steps 2-8 to perform the re-zero calibration process again. Note: The passenger seat signal is designed to change slowly; you may need to wait up to 15 seconds for it to reflect the current seat state. Note: If the re-zero calibration is not successful after 3 attempts, contact Service Engineering for further instructions.
- Reinstall all components that were removed for access.
