Operation
Turn signal indicator
+e3 This indicator flashes, as do the same side of turn-signal light
flashes. If the turn-signal light is burnt out, the blinking of
indicator slows down.
This indicator is common with hazard light.

his seat belt.
BRAKE
Brake warning light
This warning light comes on when the ignition key is in “ON”
position, and goes off after the engine has started. This
warning light comes on when the parking brake is applied
or brake fluid level falls less than the specific level.
III Charging warning light This warning light comes on when the ignition key is in
- + “ON” position, and goes off after the engine has started.
This warning light comes on when the drive belt breaks
or the trouble occurs in the charging system.
Oil pressure warning light This warning light comes on when the ignition key is in “ON”
P position, and goes off after the engine has started. This
warning light comes on when the oil fails or the trouble
occurs in the oil circulating system.
00
Overdrive indicator
This indicator will illuminates when the overdrive control
OFF
switch is switched to the “OFF” position.
68R0133
A/T
A/T oil temperature warning light This A/T oil temperature warning light comes on when
TEMP automatic transmission fluid temperature becomes abnor-
mally high.

Free-wheeling hub indicator
YEL This indicator comes on when the automatic free-wheeling
hubs are locked.
68WO80
z4 4WD indicator This indicator will light up when the transfer case shift lever is
shifted to the four wheel driving position (either the “4H” or the
“4L” position) and the ignition key is in the “ON” position.
CHECK
EGR
EGR warning light The EGR warning light will illuminate every 50,000 miles of
driving. When this occurs, bring the vehicle to an authorized
dealter to have the EGR system checked.

Circuit Diagram

SPECIFICATIONS
GENERAL SPECIFICATIONS VEHICLE-SPEED SENSOR (REED-TYPE SWITCH)
The vehicle-speed sensor functions to substitute pulse signals
for the rotations (vehicle speed) of the transmission’s output
gear;/ t i is located within the speedometer.
Pulse signals are generated when the speedometer cable
rotates.
AUTbMATlC FREE-WHEELING HUB INDICATOR
CONTROL UNIT
The control unit is located at the upper part of the right cowl
side.
The control unit is composed of the pulse-detection circuit
(which receives the input signals from the pulse generator),
the vehicle-speed-detection circuit (which receives the input
signals from the vehicle-speed sensor), the lock-discrimination
circuit (which, based on both of these input signals, judges the
condition of the automatic free-wheeling hub ‘and then trans-
mits indicator output signals to the memory circuit), and the
memory circuit (which “memorizes” the indicator output
signals from the lock-discrimination circuti).
