1. To enter the instrument cluster self-diagnostic mode, simultaneously press and hold the set button and turn the ignition switch from position 0 to position II.
2. Entry to self-diagnostic mode is confirmed when 'TEST' is displayed in the odometer's liquid crystal display (LCD).

4. Self-diagnostic mode is deactivated when the ignition switch is turned to the OFF position or low battery voltage is detected.
5. If input data to the instrument cluster is missing or invalid, the tripmeter LCD will display '----'.
6. If the self-diagnostic mode cannot be activated, test the instrument cluster using the Ford diagnostic device.
