Gauges (cont'd)
- How the Circuit Works
When the ignition switch is in ON (ll) or START (lll),
battery voltage is supplied through fuse 25 to the
gauges in the gauge assembly.
Speedometer and Odometer
The odometer and speedometer drive circuits
receive pulses lrom the vehicle speed sensor
(VSS). The pulse rate increases as the car
accelerates. The frequency and duration of these
input pulses are measured and displayed by the
speedometer, odometer and tripmeter.
Tachometer ('98-'99 Models)
The tachometer drive circuit receives oulses from
the ignition control module (lCM) in the distributor
assembly. The solid-state tachometer then displays
these pulses as engine speed. For each 200 pulses
per minute from the ignition control module (lCM),
the tachometer displays 100 RPM.
Tachometer ('00 Model)
The tachometer drive circuit receives pulses f rom
the PCM or ECM. The solid-state tachometer then
displays these pulses as engine speed. For each
200 oulses oer minute trom the PCM or ECM the
tachometer displays 1 00 RPM.
Engine Coolant Temperature Gauge and Fuel
Gauge
The engine coolant temperature gauge has two
intersecting coils wound around a permanent
magnet rotor. Voltage applied to the coils, through
fuse 25, generates a magnetic field. The magnetic
field, controlled by the engine coolant temperature
gauge sending unit, causes the rotor to rotate and
the gauge needle to move. As the resistance in the
sending unit varies, current through the gauge coils
changes. The gauge needle moves toward the coil
with the strongest magnetic tield. The fuel gauge
works the same way.
The engine coolant temperature gauge sending
unit's resistance varies from about 137 ohms at low
engine temperature to between 30-46 ohms at high
temperature (radiator fan running).
The fuel gauge sending unit's resistance varies from
about 2-5 ohms at full, to about 110 ohms at empty.
When you turn the ignition switch to LOCK (0), the
gauge remains at the last reading until you turn lhe
ignition switch to ON (ll) or START (lll) again.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.

Power Windows (conrd)
- How the Circuit Works
CAUTION: You could iniure your arms, hands,
or fingers if you unintentionally switch the
driver's window to "automatic down,' while
working in that door with the power on. Discon-
nect the window switch connector or the battery
when working in the driver's door.
System Description
The operation of the power windows is controlled by
the main switch in the power window masler switch.
When the main switch is in OFF, only the driver's
door window can be opened or closed. With the main
switch ON, all windows can be opened or closed
either by switches in the master panel, or switches in
the doors. The driver's window switch also has an
automatic down mode which is tumed on by pushing
the switch down to its second position.
The power windows are driven by reversible motors.
Each motor is protected by a built-in circuit breaker.
lf the window switch is held on too long (with the
window obstructed, or after the window is fully up or
down), the circuit breaker opens the circuit. The
circuit breaker resels automaticallV as it cools.
Driver's Window
With the ignition switch in ON (tt), vottage isprovided to the coil ol the power window relay
through fuse 24. The contacts of the power window
relay close, and voltage is applied to the driver's
switch. When you push the power window master
switch to Uq voltage is applied to the driver's power
window motor. (The motor's ground path is backthrough the power window master switch.) The
driver's window motor then drives the window uo.
When you push the switch to DOWN, voltage ls
applied in the opposite direction and the motor
drives the window down.
Automatic Down (Driver's Window)
With the ignition switch in ON (tl), vottage is applied
to the coil of the power window relay. The contacts
of the power window relay close and voltage is
applied to the power window master switch. When
you push the driver's switch to the AUTO DOWN
position, voltage is applied through the drivels
switch to the driver's window motor. The control unit
receives pulses at the pulser input while the motor
is running. When the window is fully down, the
motor stops, and pulses are no longer generated by
the pulser. This is sensed by the control unit at thepulsBr input, and voltage is no longer applied to the
driver's window motor.
Passenger Windows
With the ignition switch in ON (tt), vottage is apptied
to the coil of the power window relay through fuse
24. The contacts of the power window relay then
close, applying voltage to the individual window
switches and the power window master switch. With
the master panel main switch ON, the passenger
windows can be operated from the individual
window switches or from the master Danel switches.
When you push the front passenger's window
switch to UR voltage is applied to the front
passenger's window motor. (The motor is grounded
through the contacts in the front passenger's window
switch and the power window master switch.) The
wndow moves up as long as you hold the switch in
lhe UP position. lf you push the switch to DOWN,
voltage is applied in the opposite direction io the
front passenger's window motor, and the window
moves down as long as you hold the switch in the
DOWN position. The window switches in the other
doors operate similarly.
When you push the front passenger's switch in the
master panel to UP, voltage is applied through the
front passengeas window switch contacts to the
front passenger's window motor (The motor is
grounded through the contacts in the front
passenger's window switch and the power window
master switch.) The window moves up as long asyou hold the switch in the UP position. lf you push
the switch to DOWN, voltage is applied in the
opposite direction to the front passenger's window
motor, and the window moves down as long as you
hold the switch in the DOWN position. The otherpassenger window switches in the master panel
operate similarly.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.

- How The Circuit Wo
With the ignition switch ON (ll), voltage is applied
through fuse 24 to the coil of the moonroof relay.
The moonroof relay energizes and voltage is
applied from fuse 49 through the closed contacts of
the moonroof relay to the moonroof switch.
Open Operation
When you push the moonroof switch to the OPEN
position, voltage is applied to the moonroof motor.
The moonroot motor is grounded through the
CLOSE contacts of the moonroof switch, and the
motor runs to open the moonroof
Close Operation
When you push moonroof switch to the CLOSE
position, voltage is applied to the moonroof motor.
The moontoof motor is grounded through the OPEN
contacts of the moonroof switch, and the motor runs
to close the moonroof.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.
