If the DTC sets following a calibration of the door actuator, inspect the door and the actuator for the following conditions:
- A misaligned actuator
- Broken linkages or binding linkages
- A broken door or a binding door
- An obstruction that prevents the door from operating within the full range of motion
- Missing seals to the door
- Poor connections at the harness connector of the door actuator
