POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
Ithrough 10A fuse [No. 16, located in the fuse block (J/B)]
I to combination meter terminal 27.
With the ignition switch in the ON or START position, power is supplied
I through 10A fuse [No. 12, located in the fuse block (J/B)]
I to combination meter terminal 28.
Ground is supplied
I through body grounds F36, F47 (LHD models) or M33, M754 (RHD models)
I to combination meter terminal 29.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
Thermal transmitter provides a engine coolant temperature signal to combination meter for water temperature
gauge.
TACHOMETER
The tachometer indicates engine speed in revolution per minutes (rpm). ECM provides an engine speed sig-
nal to combination meter for tachometer.
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
Ifrom body grounds B10 and B18
I through terminal 3 of the fuel level sensor unit and
I through terminal 2 (TD27Ti engine) or 1 (ZD30DDTi engine) of the fuel level sensor unit
I to combination meter terminal 13 for the fuel gauge.
SPEEDOMETER
The combination meter receives a signal from vehicle speed sensor. The speedometer converts the signal into
the vehicle speed displayed.
AMBIENT TEMPERATURE GAUGE
Ambient temperature sensor provides the signal for ambient temperature to combination meter.

System Description
The rear window defogger system is controlled by the time control unit. The rear window defogger operates
only for approximately 15 minutes.
Rear window defogger switch is built into the A/C control panel.
Power is supplied at all times
Ithrough 10A fuse [No. 5, located in the fuse block (J/B)]
I to time control unit terminal U09.
With the ignition switch in the ON or START position, power is supplied
I through 10A fuse [No. 26, located in the fuse block (J/B)]
I to time control unit terminal U01
I to rear window defogger relay coil power side.
Ground is supplied
I to time control unit terminal U16
I through terminal MM2 of fuse block (J/B)
I through body grounds F36, F47 (LHD models) or M33, M754 (RHD models)
I to terminal 5 of A/C control panel (rear window defogger switch)
I through body grounds M33 and M754.
When the rear defogger switch is turned ON, ground is supplied
I through terminals 3 and 5 of A/C control panel (rear defogger switch)
I through terminal M19 of fuse block (J/B)
I to time control unit terminal U03.
Terminal U13 of time control unit then supplies ground to the rear window defogger relay coil ground side.
With power and ground supplied, the rear window defogger relay is energized.
Power is supplied
I through 15A fuse [No. 14 and No. 15, located in the fuse block (J/B)]
I to the rear window defogger terminal 1
I through 10A fuse [No. 1, located in the fuse block (J/B)]
I to door mirror LH/RH (defogger) terminal 3.
Ground is supplied
I to rear window defogger terminal 2
I to door mirror LH/RH terminal 2
I through body grounds B10 and B18.
With power and ground supplied, the rear window defogger filaments heat and defog the rear window.
When the system is activated, the rear window defogger indicator illuminates in the rear window defogger
switch.
