Gas Fuel Finished, Status
The value indicates the status of the combined instrument panel for the gas level in the fuel tank. This data is sent to the LPG control module. When the gas level is low and the LPG control module receives a signal indicating this from combined instrument panel terminal #B12, gas power is switched off and the engine switches to gasoline power. Approximately 5 liters and less is considered as low level. Gas power is available when the gas level is above the minimum level.
Yes = Gas level finished (low level or less).
No = Gas level OK (above low level).
NOTE:
Only applies to bi-fuel cars.
