3)Apply the first coating of undercoat to all welded areas and panel joints, then apply a second coat over the
entire area.
4)Do not coat parts which become hot, such as the tailpipe, or moving parts, such as the propeller shaft.
5)Besides the locations described below, apply undercoating to all weld points under the body to insure corrosion prevention.
6)Be sure to seal the edge of the flange of the member and bracket with undercoating.
7)If undercoat is damaged by peeling, cracks, etc., be sure to repair as necessary.
8)Before the undercoat apply sealer allowing rust prevention to be attained.
REFERENCE
Referring to the notes above, undercoating should be applied according to the specifications for your country.

INTRODUCTION
PRECAUTIONS FOR REPAIRING BODY
STRUCTURE PANELS
1.HEAT REPAIR FOR BODY STRUCTURE
PANELS
Toyota prohibits the use of the heat repair method on body
structure panels when repairing a vehicle damaged in a collision.
Panels that have high strength and rigidity, as well as a long
life span for the automobile body are being sought after.
At Toyota, in order to fulfill these requirement, we use high
tensile strength steel sheets and rust preventive steel
sheets on the body.
High tensile steel sheets are made with alloy additives and
a special heat treatment in order to improve the strength.
To prevent the occurrence of rust for a long period of time,
the surface of the steel is coated with a zinc alloy.
If a body structure parts are heat repaired with an acetylene
torch or other heating source, the crystalline organization of
the steel sheet will change and the strength of the steel
sheet will be reduced.
The ability of the body to resist rust is significantly lowered
as well since the rust resistant zinc coating is destroyed by
heat and the steel sheet surface is oxidized.
2.STRUCTURE PANEL KINKS
A sharp deformation angle on the panel that cannot be returned to its original shape by pulling or hammering is
called a kink.
Since structure parts were designed to exhibit a 100% performance when they were in their original shape, if they are
deformed in an accident, or if the deformed parts are repaired and reused, they become unable to exhibit the same
performance as intended in the design.
It is necessary to replace the part where the kink has occurred.
INTRODUCTION
3.IMPACT BEAM REPAIR
The impact beam and bracket are necessary and important
parts in maintaining a survival space for passengers in a
side collision.
For impact beam, we use special high tensile strength
steel.
The high tensile strength steel maintains its special crystalline organization by heat treatment or alloy additives.
Since these parts were designed to exhibit a 100% performance when they were in their original shape, if they are
deformed in an accident, or if the deformed parts are repaired and reused, they become unable to exhibit the same
performance as intended in the design.
It is necessary to replace the door assembly when impact
beam or bracket is damaged.

INTRODUCTION
HANDLING PRECAUTIONS ON RELATED COMPONENTS
1.BRAKE SYSTEM
The brake system is one of the most important safety components. Always follow the directions and
notes given in section BR of the repair manual for the relevant model when handling brake system parts.
NOTICE: When repairing the brake master cylinder or TRAC system, bleed the air out of the TRAC system.
2.DRIVE TRAIN AND CHASSIS
The drive train and chassis are components that can have great effects on the running performance and
vibration resistance of the vehicle. After installing components in the sections listed in the table below,
perform alignments to ensure correct mounting angles and dimensions. Particularly accurate repair of
the body must also be done to ensure correct alignment.
HINT: Correct procedures and special tools are required for alignment. Always follow the directions given in the repair manual for the relevant model during alignment and section DI of this section.

Rear WheelsRear Suspension (27) section

3.COMPONENTS ADJACENT TO THE BODY PANELS
Various types of component parts are mounted directly on or adjacently to the body panels. Strictly observe the following precautions to prevent damaging these components and the body panels during handling.
! Before repairing the body panels, remove their components or apply protective covers over the com-
ponents.
! Before prying components off using a screwdriver or a scraper, etc., attach protective tape to the tool
tip or blade to prevent damaging the components and the body paint.
! Before removing components from the outer surface of the body, attach protective tape to the body to
ensure no damage to painted areas.
HINT: Apply touch-up paint to any damaged paint surfaces.
! Before drilling or cutting sections, make sure that there are no wires, etc. on the reverse side.
4.ECU (ELECTRONIC CONTROL UNIT)
Many ECUs are mounted in this vehicle.
Take the following precautions during body repair to prevent damage to the ECUs.
! Before starting electric welding operations, disconnect the negative (–) terminal cable from the bat-
tery.
When the negative (–) terminal cable is disconnected from the battery, memory of the clock and audio
systems will be cancelled. So before starting work, make a record of the contents memorized by each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat and outside rear view mirror, which are
all equipped with memory function, it is not possible to make a record of the memory contents.
So when the operation is finished, it will be necessary to explain this fact to the customer, and request
the customer to adjust the features and reset the memory.
! Do not expose the ECUs to ambient temperatures above 80"C (176"F).
NOTICE: If it is possible the ambient temperature may reach 80"C (176"F) or more, remove the ECUs
from the vehicle before starting work.
! Be careful not to drop the ECUs and not to apply physical shocks to them.

2.PREPARATION FOR INSTALLATION
(a)SPOT WELD POINTS
(1)When welding panels with a combined thickness of
over 3mm (0.12in.), use a MIG (Metal Inert Gas) welder for plug welding.
HINT: Spot welding will not provide sufficient durability
for panels over 3mm (0.12in.) thick.
(b)APPLICATION OF WELD-THROUGH PRIMER
(SPOT SEALER)
(1)Remove the paint from the portion of the new parts
and body to be welded, and apply weld-through primer.

(d)SAFETY PRECAUTIONS FOR ELECTRICAL COM-
PONENTS
(1)When welding, there is a danger that electrical compo-
nents will be damaged by the electrical current flowing
through the body.
(2)Before starting work, disconnect the negative terminal
of the battery and ground the welder near the welding
location of the body.
(e)ROUGH CUTTING OF JOINTS
(1)For joint areas, rough cut the new parts, leaving 20 –
30mm (0.79 – 1.18in.) overlap.

(b)WELDING PRECAUTIONS
(1)The number of welding spots should be as follows.
Spot weld: 1.3 X No. of manufacturer’s spots.

5.ANTI-RUST TREATMENT AFTER PAINTING
PROCESS
(a)ANTI-RUST AGENT (WAX) APPLICATION
(1)To preserve impossible to paint areas from corrosion,
always apply sufficient anti-rust agent (wax) to the inside of the hemming areas of the doors and hoods,
and around the hinges, or the welded surfaces inside
the boxed cross-section structure of the side member,
body pillar, etc.

Painting prevents corrosion and protect the sheet
metal from damage. In this section, anti-chipping paint
only for anti-corrosion purpose is described.
(a)ANTI-CHIPPING PAINT
(1)To prevent corrosion and protect the body from dam-
age by flying stones, etc., apply anti-chipping paint to
the rocker panel, wheel arch areas, balance panel,
etc.
HINT:
Depending on the model or the application area, there
are cases where the application of anti-chipping paint
is necessary before the second coat or after the top
coat.
