Tesla Model S: 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.
