how to fix error code B0087 in Tesla Model Y Current (2020-present)

Solution

1. Preparation

• Ensure the vehicle is parked on a flat surface and turn off the ignition.
• Disconnect the 12V battery to prevent any electrical shock or short circuit during repairs.

2. Remove the Passenger Seat

• Using a socket set, remove the bolts securing the passenger seat to the floor.
• Carefully disconnect the electrical connectors from the base of the seat.
• Lift the seat out of the vehicle and place it on a soft surface to avoid scratches.

3. Inspect and Replace the Seat Occupancy Sensor

• Locate the seat occupancy sensor, typically found on the bottom of the seat cushion.
• Check for any visible damage or wear on the sensor and its wiring.
• If damaged, carefully disconnect the sensor from its connector and remove it from the seat.
• Install the new seat occupancy sensor, ensuring it is securely connected.

4. Reinstall the Passenger Seat

• Position the seat back into the vehicle and reconnect the electrical connectors.
• Align the seat with the mounting holes and secure it using the bolts previously removed.
• Torque the bolts to the manufacturer's specified value (usually around 30 Nm for seat bolts, but consult the service manual for exact specifications).

5. Reconnect the Battery and Test

• Reconnect the 12V battery and ensure all connections are secure.
• Start the vehicle and check for the airbag warning light.
• Use the OBD-II scanner to clear the error codes and verify that B0087 does not reappear.
