Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, trim removal tool.
Disconnect the vehicle battery to prevent electrical shock or short circuits.
Allow the vehicle to sit for at least 15 minutes after disconnection.

2. Inspect Wiring and Connectors

Remove the driver's seat from the vehicle using a socket set to unscrew the mounting bolts.
Disconnect the wiring harness from the seat position sensor located on the seat frame.
Visually inspect the wiring and connectors for fraying, corrosion, or loose connections.
If damage is found, repair or replace the wiring harness as needed.

3. Test the Seat Position Sensor

Use a multimeter to measure the resistance across the seat position sensor terminals.
Compare the readings to the Ford specifications found in the service manual.
If the sensor is out of spec, replace the seat position sensor with a new part.

4. Reassemble and Connect

Reconnect the wiring harness to the seat position sensor.
Position the driver's seat back into the vehicle and secure it with the mounting bolts.
Reconnect the vehicle battery and ensure all electrical connections are secure.

5. Clear the Codes and Test

Use the OBD-II scanner to clear the B2275 code from the vehicle's system.
Perform a test drive to ensure the seat functions operate correctly and monitor for any reoccurrence of the code.
