- When working with the engine running, make sure to provide
ventilation for exhaust
fumes in the workshop.
- If working on high temperature, high pressure, rotating, moving,
or vibrating parts,
wear appropriate safety equipment and take extra care not to injure

Preparation of tools and
measuring gauge |
Before starting the operation, prepare a tool stand, sst, gauge, oil
and parts for
replacement. |
5 |
Removal and installation,
disassembly and assembly
operations |
- Diagnose with a thorough understanding of proper procedures and
of the reported
problem.
- Before removing parts, check the general condition of the
assembly and for
deformation and damage.
- When the assembly is complicated, take notes. For example, note
the total number of
electrical connections, bolts, or hoses removed. Add matchmarks to
ensure
reassembly of components to their original positions. Temporarily
mark hoses and
their fittings if needed.
- Clean and wash the removed parts if necessary and assemble them
after a thorough
check.
|
6 |
Removed parts |
- Place removed parts in a separate box to avoid mixing them up
with new parts or
contaminating new parts
- For non-reusable parts such as gaskets, o-rings, and
self-locking nuts, replace them
with new ones as instructed in this manual.
- Retain the removed parts for customer inspection, if requested.
|
- Jacking up and supporting vehicle
- Care must be taken when jacking up and
supporting the vehicle. Be sure to lift and
support the vehicle at the proper locations.
- Precoated parts
- Precoated parts are bolts and nuts that are
coated with a seal lock adhesive at the factory.
- If a precoated part is retightened, loosened or
moved in any way, it must be recoated with the
specified adhesive.
- When reusing a precoated part, clean off the old
adhesive and dry the part with compressed air.
Then apply new seal lock adhesive appropriate
to that part.
- Some seal lock agents harden slowly. You may
have to wait for the seal lock adhesive to
harden.
- Gaskets
- When necessary, use a sealer on gaskets to
prevent leaks.
- Bolts, nuts and screws
- Carefully follow all the specifications for
tightening torques. Always use a torque wrench.
- Fuses
- When inspecting a fuse, check that the wire of
the fuse is not broken.
- When replacing fuses, be sure that the new fuse
has the correct amperage rating. Do not exceed
the rating or use one with a lower rating.
- Clips
Hint:
If clips are damaged during a procedure, always
replace the clips with new clips.
- The removal and installation methods of typical
clips used for vehicle body parts are shown in
the table below.
- Claws
- The removal and installation methods of typical
claws used for vehicle body parts are shown in
the table below.
Hint:
If claws of caps or covers are damaged during a
procedure, always replace the caps or covers
with new ones.
- Removal and installation of vacuum
hoses.
- To disconnect a vacuum hose, pull and twist
from the end of the hose. Do not pull from the
middle of the hose as this may cause damage.
- When disconnecting vacuum hoses, use tags to
identify where they should be reconnected.
- After completing any hose related repairs,
double-check that the vacuum hoses are
properly connected. The label under the hood
shows the proper layout.
- When using a vacuum gauge, never force the
hose onto a connector that is too large. If a hose
has been stretched, it may leak air. Use a stepdown
adapter if necessary.
- Torque when using torque wrench with extension tool
- Use the formula below to calculate special
torque values for situations where sst or an
extension tool is combined with a torque wrench.
Formula:
t' = l2 / (l1 + l2) * t
Notice:
If an extension tool or sst is combined with
a torque wrench and the wrench is used to
tighten to a torque specification in this
manual, the actual torque will be excessive
and parts will be damaged.
The rav4 is equipped with a supplemental restraint
system (srs). The srs of this vehicle consists of the
following:

Blower motor circuit
Description
When the heater control (blower switch) is set to position 1 or higher, the
contact of the htr relay is
closed, current flows to the blower motor, and the blower motor operates. The
blower motor speed can be
changed by exchanging the ground and the blower resistor circuit with the ...
Problem symptoms table (2006/01- )
Hint:
Use the table below to help determine the cause of the
problem symptom. The potential causes of the symptoms
are listed in order of probability in the "suspected area"
column of the table. Check each symptom by checking the
suspected areas in the order they are listed. Re ...
Throttle / pedal position sensor / switch "A"
Hint:
These dtcs relate to the throttle position (tp) sensor.
Description
The tp sensor is mounted on the throttle body, and detects the opening angle
of the throttle valve. This
sensor is a non-contact type. It uses hall-effect elements in order to yield
accurate signals even in
extrem ...
