Stop Light Warning Light
The light is connected to the stop light checker. This checker
consists of a reed switch and magnet coils
CD
and
®,
as
shown in figure. Under normal conditions, the magnetic fields
are generated in the magnet coils
CD
and
®
by the current
flowing through each light while the stop light switch is ON.
These magnetic fields cancel each other because the coils turn
in directions opposite to each other. As a result, the reed
switch will remain OFF, and the warning light is OFF. If
either the left or right hand side stop light fails, current will
flow through only one magnet coil, and the resultant magnetic
field causes the reed switch to turn ON. Therefore, the
warning light will remain lighted as long as the brake pedal is
depressed.
The light will not come ON if both right and left lamp bulbs
burn out simultaneously.

Brake Fluid Level Warning Light
The light is connected to the brake fluid level sensor that is
incorporated in brake fluid reserve tank.
If brake fluid decreases to less than the specified volume in the
reservoi r, the sensor is actuated and the I ight comes on wh i Ie
the engine is running.
Total brake fluid volume in reservoir:

a. For checking if bulb of brake fluid level warning light is
burned out, make sure that the warning light glows when
ignition switch is initially turned to "ON" and it goes out
when engine is running.
b. If brake fluid reservoir is inclined or vibrated abnormally,
the warning light may be lighted momentarily even fluid level
is above the specified limit.

CHECK ENGINE Warning Light
The warning light is provided for the purpose of indicating the
condition of the MPF I system. If the MPF I system is faulty,
the warning light will come on while the engine is running.
For troubleshooting, refer to the chapter titled "2-7 Fuel
Injection System".
STEERING Warning Light
This light comes on when trouble occurs in electronic-
controlled motor drive power steering system while engine is
running. It also functions as a monitor light when diagnosing
the steering system. For troubleshooting, refer to Chapter
4-3
"Steering System".
Low Fuel Indicator Light
The indicator light is operated by thermistor incorporated in
fuel unit on fuel tank, and goes on when amount of gasoline
in fuel tank is less than the specified volume as shown below.
