PRECAUTIONS
General Precautions
EAS000FQ
lDo not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any
inflammable or poisonous materials, such as gasoline, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials.
Do not smoke while working on the vehicle.
lBefore jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.
lWhen removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
lBefore starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
lIf the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.
lTo prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
lDispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.
lDo not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.
lClean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
lReplace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.
lReplace inner and outer races of tapered roller bearings and needle bearings as a set.
lArrange the disassembled parts in accordance with their assembled locations and sequence.
lDo not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
lAfter disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.

HOW TO USE THIS MANUAL
GI-11
1.Before performing trouble diagnoses, read the “Preliminary Check”, the “Symptom Chart” or the
“Work Flow”.
2.After repairs, re-check that the problem has been completely eliminated.
3.Refer to Component Parts and Harness Connector Location for the Systems described in each
section for identification/location of components and harness connectors.
4.Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continuity between harness connectors in more detail, such as when a
sub-harness is used, refer to Wiring Diagram in each individual section and Harness Layout in PG
section for identification of harness connectors.
5.When checking circuit continuity, ignition switch should be OFF.
6.Before checking voltage at connectors, check battery voltage.
7.After accomplishing the Diagnostic Procedures and Electrical Components Inspection, make sure
that all harness connectors are reconnected as they were.
HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES
