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.
Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.

ComponentsAAS000GW
THE LARGE ILLUSTRATIONS are exploded views (See the following) and contain tightening torques,
lubrication points, section number of the PARTS CATALOG (e.g. SEC. 440) and other information neces-
sary to perform repairs.
The illustrations should be used in reference to service matters only. When ordering parts, refer to the
appropriate PARTS CATALOG .
Components shown in an illustration may be identified by a circled number. When this style of illustration
is used, the text description of the components will follow the illustration.

torque.
Should be lubricated with grease. Unless otherwise indicated, use recommended multi-purpose grease.
Should be lubricated with oil.
Sealing point
Checking point
Always replace after every disassembly.
PApply petroleum jelly.
Apply ATF.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
Revision: 2004 November 2004 FX35/FX45
Do not apply excessive shock to the control unit by dropping or
hitting it.
Be careful to prevent condensation in the control unit due to
rapid temperature changes and do not let water or rain get on it.
If water is found in the control unit, dry it fully and then install it in
the vehicle.
Be careful not to let oil to get on the control unit connector.
Avoid cleaning the control unit with volatile oil.
Do not disassemble the control unit, and do not remove the
upper and lower covers.
When using a DMM, be careful not to let test probes get close to
each other to prevent the power transistor in the control unit
from damaging battery voltage because of short circuiting.
When checking input and output signals of the control unit, use
the specified check adapter.

Filament CheckAIS004RH
1. When measuring voltage, wrap tin foil around the top of the neg-
ative probe. Then press the foil against the wire with your finger.
2. Attach probe circuit tester (in Volt range) to middle portion of
each filament.
3. If a filament is burned out, circuit tester registers 0 or battery
voltage.
4. To locate burned out point, move probe to left and right along fil-
ament. Test needle will swing abruptly when probe passes the
point.
