Low Fuel Indicator Light Inspection
1. Disconnect the fuel tank unit wire connector.
2. Turn the key switch on. Check that the bulb lights.
If operation is not correct, remove and check the bulb or circuit.
or If check whether low fuel turns on fuel input (B-24) at the
time of open and key on.
 meter is check at low fuel
140R300006





Check level sensor operation
1. Remove the fuel tank unit.
2.
Apply battery voltage between terminal (B) and (C) through
a 1.12 watt bulb. Check that the bulb lights.
Note:
It will take a short time for the bulb light.
3. Submerge the sensor in fuel. Check that the bulb goes out.
If operation is not correct, replace the fuel tank unit.

BRAKE SYSTEM WARNING LIGHT
The brake system warning light comes on while the parking
brake is set and the engine run position.
Note:
The parking brake indicator light circuit is designed to
prevent driving of the vehicle with the parking brake on.
It does not indicate the condition of the parking brake
system.



The parking brake switch is in parallel with the brake fluid
switch.



The brake system warning light also comes on when reservoir
brake fluid level falls below the specified limit with the parking
brake released and the engine run position.

6B-6 ENGINE COOLING

















Draining and Refilling Cooling
System
Before draining the cooling system, inspect the system and
perform any necessary service to ensure that it is clean, does
not leak and is in proper working order. The engine coolant
(EC) level should be between the "MIN" and "MAX" lines of
reserve tank when the engine is cold. If low, check for leakage
and add EC up to the "MAX" line. There should not be any
excessive deposit of rust or scales around the radiator cap or
radiator filler hole, and the EC should also be free from oil.
Replace the EC if excessively dirty.
1. Completely drain the cooling system by opening the drain
plug at the bottom of the radiator.
2. Remove the radiator cap.
WARNING: TO AVOID THE DANGER OF BEING BURNED,
DO NOT REMOVE THE CAP WHILE THE ENGINE AND
RADIATOR ARE STILL HOT. SCALDING FLUID AND
STEAM CAN BE BLOWN OUT UNDER PRESSURE.
3. Disconnect all hoses from the EC reserve tank.
Scrub and clean the inside of the reserve tank with soap
and water. Flush it well with clean water, then drain it. Install
the reserve tank and hoses.
4. Refill the cooling system with the EC using a solution that is
at least 50 percent antifreeze.
5. Fill the radiator to the base of the filler neck.
Fill the EC reserve tank to "MAX" line when the engine is
cold.
6. Block the drive wheels and firmly apply the parking brake.
Shift an automatic transmission to "P" (Park) or a manual
transmission to neutral.
7. Remove the radiator cap. Start the engine and warm it up a
t
2,500 - 3,000 rpm for about 30 minutes.
8. When the air comes out from the radiator filler neck and the
EC level has gone down, replenish with the EC. Repeat this
procedure until the EC level does not go down. Then stop
the engine and install the radiator cap. Let the engine cool
down.
9. After the engine has cooled, replenish with EC up to the
"MAX" line of the reserve tank.
10. Start the engine. With the engine running at 3,000 rpm,
make sure there is no running water sound from the heate
r
core (behind the center console).
11. If the running water sound is heard, repeat steps 8 to 10.

ENGINE ELECTRICAL 6D1-5











































Battery fluid is a highly corrosive acid.
Should battery fluid come in contact with your eyes, skin,
fabric, or a painted surface, immediately and thoroughly rinse
the affected area with clean tap water.
Never allow metal tools or jumper cables to come in contact
with the positive battery terminal, or any other metal surface of
the vahicle. This will protect against a short circuit.
Always keep batteries out of reach of young children.
Jump Starting Procedure
1. Set the vehicle parking brake.
If the vahicle is equipped with an automatic transmission,
place the selector level in the "PARK" position.
If the vehicle is equipped with a manual transmission, place
the shift lever in the "NEUTRAL" position.
Turn "OFF" the ignition.
Turn "OFF" all lights and any other accessory requiring
electrical power.
2. Look at the built-in hydrometer.
If the indication area of the built-in hydrometer is completely
clear, do not try to jump start.
3.
Attach the end of one jumper cable to the positive terminal
of the booster battery.

Attach the other end of the same cable to the positive
terminal of the discharged battery.
Do not allow the vehicles to touch each other. This will
cause a ground connection, effectively neutralizing the
charging procedure.
Be sure that the booster battery has a 12 volt rating.
4.
Attach one end of the remaining cable to the negative
terminal of the booster battery.

Attach the other end of the same cable to a solid engine
ground (such as the air conditioning compressor bracket o
r
the generator mounting bracket) of the vehicle with the
discharged battery.
The ground connection must be at least 450 mm (18 in.)
from the battery of the vehicle whose battery is being
charged.
WARNING: NEVER ATTACH THE END OF THE JUMPER
CABLE DIRECTLY TO THE NEGATIVE TERMINAL OF THE
DEAD BATTERY.
5. Start the engine of the vehicle with the good battery.
Make sure that all unnecessary electrical accessories have
been turned "OFF".
6. Start the engine of the vehicle with the dead battery.
7. To remove the jumper cables, follow the above directions in
reverse order.
Be sure to first disconnect the negative cable from the
vehicle with the discharged battery.

0A-2 GENERAL INFORMATION
GENERAL REPAIR INSTRUCTIONS
1. Park the vehicle on level ground and chock the front or rear wheels before lifting the vehicle.
2. Raise the vehicle with a jack set against the axle or the frame.
3. Support the vehicle on chassis stands.
4. Use covers on the vehicle body, seats, and floor to prevent damage and/or contamination.
5. Disconnect the grounding cable from the battery before performing service operations.

This will prevent cable damage or burning due to short circuiting.
6. Handle brake fluid and antifreeze solution with great care.

Spilling these liquids on painted surfaces will damage the paint.
7. The use of the proper tool(s) and special tool(s) where specified is essential to efficient, reliable, and safe
service operations.
8. Always use genuine ISUZU replacement parts.
9. Discard used cotter pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts at disassembly.
Normal function of these parts cannot be guaranteed if they are reused.
10. Prepare new cotter pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts for installation.
11. Keep the disassembled parts neatly in groups.
This will facilitate smooth and correct reassembly.
12. Keep fixing nuts and bolts separate.
Fixing nuts and bolts vary in hardness and design according to installation position.
13. Clean all parts before inspection or reassembly.
14. Clean the oil ports and other openings with compressed air to make certain that they are free from dirt and
obstructions.
15. Lubricate the rotating and sliding faces of all moving parts with oil or grease before installation.
16. Use the recommended liquid gasket to prevent leakage.
17. Carefully observe all nut and bolt torque specifications.
18. When removing or replacing parts that require refrigerant to the discharged from the Air conditioning system, be
sure to use the Vehicle Refrigerant Recovery and Recycling Equipment (VRRRE) to recover and recycle R134a,
to promote the movement for the protection of the ozone layer covering the earth.
19. Check and recheck your work. No service operation is complete until you have done this.
