- Obstruction or binding in the back door mechanism (check for anything blocking movement)
- Damaged liftgate struts or misalignment
- Weak battery or low voltage to the motor
What You Can Try:
✅ Manual Reset Procedure (works on some models):
- Turn off the engine.
- Open the back door manually all the way.
- Close it manually and then press and hold the PBD button for 5–10 seconds.
- Try opening the door again with the button and see if it works.
✅ Inspect the Motor & Wiring:
- Remove the left side trim in the cargo area and check the motor, connector, and wiring for corrosion or damage.
- If possible, test voltage at the motor when the button is pressed.
✅ Clear the Code & Retest:
- Use a scan tool to clear the B2228 code.
- Try operating the door again and see if the code returns.
If the issue persists, the left-side motor or its circuit board may need replacement.
