Anti-Corrosion Treatment ConstructionS6RW0D9C01001
WARNING!
Standard shop practices, particularly eye protection, should be followed during the performance of the
following operations to avoid personal injury.
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 electro primer 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 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 characteristics
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 purpose 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 components.
5) Apply anticorrosion compound (penetrative wax).
6) Apply undercoating (rust proof material).

DTC P1616: Unregistered Keyless Start Control ModuleS6RW0DA304010
Wiring Diagram
Refer to “Immobilizer Control System Wiring Circuit Diagram”.
Circuit Description
P1616 is detected when ECM detects different ID codes registered in ECM and keyless start control module after
turning engine start knob to ON position. Normally, when keyless start control module is replaced with new one, ECM
automatically registers the applicable code in keyless start control module after turning ignition switch to ON position.
However, when keyless start control module is replaced with used one, ECM does not automatically register the
applicable code in keyless start control module even if ignition switch is turned to ON position.
Detecting Condition and Trouble Area
Troubleshooting6Steering lock unit power supply check
1) Connect keyless start control module connector.
2) With ignition switch at ON position, check power supply
terminal voltage of steering lock unit connector. Refer to
“Keyless Start Control Module Power and Ground Circuit
Check in Section 10E”.
Is voltage 4 – 6 V?Replace steering lock
unit and recheck.Substitute a known-
good keyless start
control module and
recheck. If DTC P1615
is still detected,
substitute a known-
good ECM and recheck. Step Action Yes No
