Revision: 2005 July 2005 FX

Before 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.

When 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.

Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.

If the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.

To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.

Dispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.

Do 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.

Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.

Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.

Replace inner and outer races of tapered roller bearings and needle bearings as a set.

Arrange the disassembled parts in accordance with their assembled locations and sequence.

Do not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.

After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.

Use only the fluids and lubricants specified in this manual.

Use approved bonding agent, sealants or their equivalents when required.

Use hand tools, power tools (disassembly only) and recom-
mended special tools where specified for safe and efficient ser-
vice repairs.

When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.

How to Follow Trouble DiagnosesAAS000E1
DESCRIPTION
NOTICE:
Trouble diagnoses indicate work procedures required to diagnose problems effectively. Observe the following
instructions before diagnosing.
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
1. Work and diagnostic procedure
Start to diagnose a problem using procedures indicated in enclosed test groups.
2. Questions and required results
