ANTI-CORROSION TREATMENT
As rust proof treatment, steel sheets are given corrosion resistance on the interior and/or exterior.
These corrosion resistance steel sheet materials are called one of two-side galvanized steel sheets.
It is for the sake of rust protection that these materials are selected and given a variety of treatments as
described blow.
Steel sheets are treated with cathodic electroprimer which is excellent in corrosion resistance.
Rust proof wax coatings are applied to door and side sill insides where moisture is liable to stay.
Vinyl coating is applied to body underside and wheel housing inside.
Sealer is applied to door hem, engine compartment steel sheet-to-steel sheet joint, and the like portions to
prevent water penetration and resulting in rust occurrence.
In panel replacement or collision damage repair, leaving the relevant area untreated as it is in any operation
which does disturb the above-mentioned rust proof treatment will cause corrosion to that area. Therefore, it is
the essential function of any repair operation to correctly recoat the related surfaces of the relevant area.
All the metal panels are coated with metal conditioners and primer coating during vehicle production. Following
the repair and/or replacement parts installation, every accessible bare metal surface should be cleaned and
coated with rust proof primer. Perform this operation prior to the application of sealer and rust proof wax coating.
Sealer is applied to the specific joints of a vehicle during production. The sealer is intended to prevent dust from
entering the vehicle and serves also as an anticorrosion barrier. The sealer is applied to the door and hood hem
areas and between panels. Correct and reseal the originally sealed joints if damaged. Reseal the attaching
joints of a new replacement panel and reseal the hem area of a replacement door or hood.
Use a quality sealer to seal the flanged joints, overlap joints and seams. The sealer must have flexible character-
istics and paint ability after it’s applied to repair areas.
For the sealer to fill open joints, use caulking material. Select a sealer in conformance with the place and pur-
pose of a specific use. Observe the manufacturer’s label-stand instructions when using the sealer.
In many cases, repaired places require color painting. When this is required, follow the ordinary techniques
specified for the finish preparation, color painting and undercoating build-up.
Rust proof wax, a penetrative compound, is applied to the metal-to-metal surfaces (door and side sill insides)
where it is difficult to use ordinary undercoating material for coating. Therefore, when selecting the rust proof
wax, it may be the penetrative type.
During the undercoating (vinyl coating) application, care should be taken that sealer is not applied to the engine-
related parts and shock absorber mounting or rotating parts. Following the under coating, make sure that body
drain holes are kept open.
The sequence of the application steps of the anti-corrosion materials are as follows:
1) Clean and prepare the metal surface.
2) Apply primer.
3) Apply sealer (all joints sealed originally).
4) Apply color in areas where color is required such as hem flanges, exposed joints and under body compo-
nents.
5) Apply anticorrosion compound (penetrative wax).
6) Apply undercoating (rust proof material).WARNING:
Standard shop practices, particularly eye protection, should be followed during the performance of the
below-itemized operations to avoid personal injury.

The adapter will also give an idea of whether contact tension is
sufficient, helping to find an open or intermittent open due to poor
terminal contact.
Special tool
(B) : 09932-75010 (Air Bag Driver/Passenger Load Tool)
This tool is used only when called for in this section. It is used as
a diagnostic aid and safety device to prevent inadvertent air bag
(inflator) module deployment.
The load tool has three connectors attached to its case which are
electrically functional and serve as resistive load substitutions.
No more than two connectors are used at any time.
One of connectors (“STEERING WHEEL”) is used to substitute
the load of followings.
driver air bag (inflator) module when it is connected at the
top of the column to the contact coil assembly.
passenger air bag (inflator) module when it is connected to
the air bag harness connector for passenger air bag (inflator)
module.
Another connector (“BASE OF COLUMN”) is used to substitute
the load of the driver air bag (inflator) module and the contact coil
assembly when it is connected at the base of the column to the air
bag wire harness.
The third connector (“PASSENGER INFLATOR”) is not used.
By substituting the resistance of the load tool when called for, a
determination can be made as to whether an inflator circuit com-
ponent is causing system malfunction and which component is
causing the malfunction.
The load tool should be used only when specifically called for in
the diagnostic procedures.
1. Connector for contact coil and driver air bag (inflator) module
(Located near the base of the steering column)
2. Connector for driver, passenger air bag (inflator) module and driver and
passenger seat belt pretensioners
3. Not used
