Actuator Calibration Function

ACTUATOR CALIBRATION FUNCTION

The Actuator Calibration function:
- is actuated with a scan tool.
- homes and repositions door actuators.
- monitors for door span faults. Door span faults (Door Travel Range Too Large or Door Travel Range Too Small) will only display after calibration.
- will cause the electric backlight (EBL) status indicator (if equipped) to flash while the test is running.
