FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
●
from unified meter and A/C amp. terminal 58
●
through the fuel level sensor unit and fuel pump (main) terminals 5 and 2, and
●
through the fuel level sensor unit (sub) terminals 2 and 1
●
to unified meter and A/C amp. terminal 42.
Unified meter and A/C amp. provides a fuel level signal to combination meter for fuel gauge with communica-
tion line between unified meter and A/C amp. and combination meter.
ODO/TRIP METER
●
ABS actuator and electric unit (control unit) converses a pulse signal from wheel sensor to vehicle speed
signal, and transmits vehicle speed signal to unified meter and A/C amp. with CAN communication.
●
Unified meter and A/C amp. converses vehicle speed signal to 8 pulse signal, and transmits to combina-
tion meter.
●
Combination meter processes the 8 pulse signal and the memory signals from the meter memory circuit.
Then the mileage is displayed.
How to Change The Display For Odo/trip Meter
Operating the odo/trip meter switch allows switching the mode in the following order.
●
The odo/trip meter display switching and trip display resetting
can be identified by the time from pressing the odo/trip meter
switch (1) to releasing it.
●
When resetting with “trip A” displayed, only “trip A” display is
reset. (The same way for “trip B”.)
