- How the Circuit Works
Do not smoke while working on the fuel system.
Keep open flame away from the work area. Drain
fuel only into an approved container.
A thermistor is mounted in the fuel tank unit. When
the thermistor is cool, its resistance is very high.
When the thermistor is warm, its resistance
decreases. Fuel in the fuel tank transfers heat away
from the thermislor last enough to keep it cool so
the thermistor's resistance stays high and the low
fuel indicator lighl does not come on. When the fuel
level drops below about 2.2 gallons, the thermistor
is no longer immersed in fuel. Without the fuel to
cool it, the thermistor's resistance decreases,
allowing current to flow through the low fuel
indicator light and the thermistor to ground, and lhe
low fuel indicator light comes on.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.

How the Circuit Works
The maintenance reminder light comes on to
remind the driver that the car is due for
scheduled mainlenance.
The maintenance reminder unit receives a vehicle
speed input from the vehicle speed sensor (VSS)
and uses this inlormation to compute the distance
traveled. For the first 6000 t 1 00 miles (9650 t 160
km) after the maintenance reminder light is reset, it
will come on for two seconds when you turn the
ignition switch to ON (ll) as a bulb check.
Between 6000 1 100 miles (9650 t 160 km) and
7500 t 100 miles (12070 I 160 km) the reminder
light will come on for two seconds when you turn
the ignition switch to ON (ll), and then flash for eight
seconds more.
Beyond 7500 t 100 miles (12070 t l60 km) the
reminder light will stay on when the ignition switch is
in the ON (ll) position until the unit is reset.
To reset the unit, the car must be parked and the
ignition switch in the ON (ll) position. Press the
reset button on the unit and hold it there for more
than three seconds, and the reminder light will
go off.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.

- How the Circuit Works
With the ignition switch in ON (ll) or START (lll),
voltage is applied to the A,/T gear position indicator.
The A,/T gear position switch provides a ground for
each position. As an input is grounded, ils indicator
light comes on. lf you se,ecl B, tor example, ground
will be applied to the input of the A,/T gear position
indicator, and the R indicator bulb will come on.
With the headlight switch in PARK or HEAD, voltage
is applied to the RED/BLK wire terminal. this
changes the indicator panel illumination from lixed
to controlled by the dash lights dimmer inpul
through the RED wire.
When the lransmission ('98.99 models) or
powertrain ('00 model) control module (TCM or
PCM) detects an abnormality in the automatic
transmission control system, or when you request
diagnostic trouble codes through the service
check connector, the TCM or PCM will make lhe D4
indicator light blink.
Refer to the Service Manual (Section 14,
Automatic Transmission) for soecific tests or
troubleshooting procedures.
