Fuel Gage
Fuel gage input signal is from the fuel level sensor, one end of
the fuel gage is connected to fuel sensor terminal.
Fuel sensor resistance parameters are as following:
Fuel Resistance
Full 40 ( ± 2 Ω)
3/4 60( ± 2 Ω)
1/2 90( ± 2 Ω)
1/4 140( ± 2 Ω)
Threshold 190 ( ± 2 Ω)
Empty 300 ( ± 2 Ω)
According to the total fuel tank capacity (55 L), LCD display is
divided into eight equal interval value (slightly different in the
low fuel alarm mode). When the fuel amount decreases, if the
current fuel level falls into the appropriate range, the
corresponding LCD segment will be lit.

When the fuel level is lower than the threshold, low fuel level
warning lamp light.
Engine Coolant Temperature Gage
Engine coolant temperature information is from the CAN bus.
Micro-controller calculates the engine coolant temperature,
and then displays on LCD according to the message sent from
the EMS.
If the CAN message from the EMS is lost continuously for one
minute, or the temperature value is invalid for one minute, LCD
thermometer will show the minimum, and the temperature
warning lamp will be on.
Temperature is displayed in eight segments on LCD. The
temperature corresponding relationships may be adjusted in
the programming and stored in EEPROM. The default
comparison is shown below.

When the engine temperature reaches 124°C (255 ºF), the
engine overheating warning lamps will be flashing at 1Hz
frequency. For detailed alarm policy, please refer to the table:
