What does 000 in the supply tank indicate on the CAD?

Explanation:
Interpreting a 000 reading in the supply tank on the CAD hinges on recognizing a fault indicator rather than a real level. The quantity measurement uses three digits, and when the transmitter or its signal path fails, a valid reading cannot be produced. The system flags this with a 000 value and an accompanying status like “F QTY Fail,” signaling a fuel-quantity sensor fault. So you should not treat it as empty or any normal level. Instead, check other indicators (another gauge or transmitter, local sight gauge) and diagnose the sensor circuit (power, wiring, transmitter health) to confirm the actual tank condition. The other states would typically be shown by valid readings or different normal-status indicators, not by a fault code.
