length of time between flashes is used to indicate certain
vehicle conditions. Refer to ”Fault or Alarm Indication” in
this section.
AUTOLOCKING (SAFETY LOCK)
The remote keyless entry system features an autolocking
feature. If the doors are unlocked with the remote transmit-
ter when the control module/receiver is in the armed
mode, the doors are automatically re–locked after 30 sec-
onds unless any of the following events occur:
S A door is opened.
S The ignition is ON.
S The trunk is opened.
S The hood is opened.
CONTROL MODULE/RECEIVER
The remote keyless entry control module/receiver is con-
tained in the floor console. The module/receiver pro-
cesses signals from the remote transmitter and various
switches. It activates the alarm if an intrusion is detected.
The control module/receiver also has a self–diagnostic
function which will display trouble codes. In order to dis-
play trouble codes, a scan tool must be connected to the
data link connector (DLC).
The control module/receiver will not communicate with
transmitters from other vehicles because there are over
four billion possible electronic password combinations. Itis highly unlikely that any transmitters will use the same
password. The control module/receiver has an attached
antenna to detect signals from the transmitter.
FAULT OR ALARM INDICATION
When the UNLOCK button on the remote transmitter is
pressed, the control module/receiver will flash the parking
lights to indicate information about the remote keyless
entry and anti–theft system.
Normal Condition: If there has not been an intrusion, and
no fault has been detected, the control module/receiver
will signal a normal condition when the UNLOCK button is
pressed. The parking lights will flash twice for 0.5 second,
with a 0.5 second pause between flashes.
Fault Indication: If there is a fault in the remote keyless
entry and anti–theft system, the control module/receiver
will signal the fault when the UNLOCK button is pressed.
The parking lights will flash twice for 1 second, with a 0.5
second pause between flashes.
Alarm Indication: If there has been an intrusion since the
last time the LOCK button was pressed, the control mod-
ule/receiver will signal that there has been an intrusion
when the UNLOCK button is pressed. The parking lights
will flash twice for 0.5 second, with a 1.5 second pause be-
tween flashes.
Alarm and fault information will be erased the next time the
transmitter arms the control module/receiver by transmit-
ting a LOCK message.

2. RUST PREVENTIVE PROCEDURE
2–1. GENERAL INFORMATION
.
Corrosion starts immediately after the steel base con-
tacts the atmosphere. The condition is aggravated by
sea wind, road salt, rain, snow and industrial fallout.
There are many ways to protect automobiles against
corrosion. Primers, primer surfacers and paints are ap-
plied by electrodeposition or spray to protect the car
body.Anti–rust Agents and Spray Guns
Use the following anti–rust agents or equivalents when
making a body repair.
.
CAUTION : ANTI–RUST agents contain substances
that are harmful if you breathe or swallow them, or get
them on your skin. Wear converalls, gloves, eye
protection, and an approved respirator while using
such agents.
.
.
Anti–rust agents:
RUSTOP
DEOX #100
WAXOYL
U.S.A. MARKET
AUTO ARMOR 1031
(made by E.C.P)To be applied to welded joints
inside body panels.
NOX–RUST 409–20S
SOLTION 1000SAUTO ARMOR OUTSIDE COATING
(made by E.C.P)To be appled to under floor
and wheelhouse.
Spray guns:
Use the correct gun for the agent being used.
S Use of a pressure type spray gun is recommended when
work involves a considerable number of cars.
For RUSTOP
DEOX#100For WAXOYLFor NOXRUST 409–20S/
SOLTION 1000S
Protectors: Wear gloves, mask and suitable eye protection.
S Use light oil and a rag to clean up spilled anti–rust agents.

Precautions:
.
1. Before applying an anti–rust agent, thoroughly clean
the areas to be coated with a steam cleaner, etc., and
let dry.
.
Note : Waxoyl may be applied to wet surface.
.
2. Spray an anti–rust agent sufficiently until the excess
amount oozes out when filling, the doors, etc. Wipe the
excess agent with a clean rag dampened with light oil.
.
3. Do not spray an anti–rust agent to the brake hoses,
brake wheel cylinders, brake drums, exhaust muffler
and its related parts, emission control devices in the en-
gine compartment, ball joint covers, etc. Wipe up spilled
agent at once.
.4. Heat an anti–rust agent to room temperature[36.5
C
(97.7
F)] by submerging the container in hot water
when outside temperature is below 10
C(50
F).
.
5. Ventilate when spraying an anti–rust agent since it
contains a small amount of organic solvent. Keep
sparks, flames and cigarettes away.
.
CAUTION : The remaining agent will harden in the
passages of the spray gun, making them unservice-
able.
