OPERATION
<Fuel gauge>
D
When the ignition switch is at the “ON” position,
the fuel gauge is activated.
D
When there is much fuel, the unit’s resistance
is small and the current flowing in the circuit
is great, so the gauge’s indicator indicates in
the “Full” area.
D
When there is little fuel, the unit’s resistance
is high and the current flowing in the circuit
is small, so the gauge’s indicator indicates in
the “Empty” area.
<Engine coolant temperature gauge>
D
When the ignition switch is at the “ON” position,
the engine coolant temperature gauge is
activated.
D
When the engine coolant temperature is high,
the unit’s resistance is low and there is a great
flow of current in the circuit, so the gauge’s
indicator indicates in the “H” area.
D
When the engine coolant temperature is low,
the unit’s resistance is high and there is a small
flow of current in the circuit, so the gauge’s
indicator indicates in the “C” area.
TROUBLESHOOTING HINTS
1. Fuel gauge does not operate, or registers
incorrectly.
(1) The fuel gauge indicates “F” when the fuel
gauge unit (sub) connector is disconnected
and the “1” terminal is earthed.
D
Check fuel gauge.
2. Engine coolant temperature gauge does not
operate, or registers incorrectly.
(1) When the engine coolant temperature
gauge is earthed with its connector
unplugged, it registers “H”.
D
Check engine coolant temperature
gauge unit.
