9T1 – 8IREMOTE KEYLESS ENTRY AND ANTI–THEFT SYSTEM
DAEWOO V–121 BL4
GENERAL DESCRIPTION
AND SYSTEM OPERATION
REMOTE KEYLESS ENTRY AND
ANTI–THEFT SYSTEM
The remote keyless entry and anti–theft system can per-
form the following functions:
S Remotely lock and unlock the vehicle doors by
means of a hand–held, high–frequency transmitter.
S Sense intrusion into the vehicle.
S Activate a warning in the event of an intrusion.
S Help the driver find the vehicle in a parking area.
S Automatically re–lock the doors if the door or the
trunk is not opened within 30 seconds after the ve-
hicle has been unlocked by the remote keyless
entry.
S Communicate serial data to a scan tool to help
diagnose system faults.
The remote keyless entry and anti–theft system consists
of the following components:
S Keyless entry and anti–theft control module/receiv-
er.
S Security indicator.
S Trunk open switch (NOTCHBACK).
S Trunk tamper switch (NOTCHBACK).
S Front door tamper switches.
S Door contact switches.
S Central door lock relay.
S Turn signal bulbs.
S Siren.
S Hood open switch.
REMOTE LOCKING AND UNLOCKING
The hand–held transmitter locks and unlocks the vehicle
doors by sending radio waves to the control module/re-
ceiver in the vehicle. The effective range of the transmitter
varies between 5 and 10 meters, (approximately 16 to 32
feet), depending on whether or not objects, such as other
vehicles are blocking the path of the radio waves.
The transmitter has a LOCK button and an UNLOCK but-
ton which only function when the ignition is OFF. Pressing
the UNLOCK button has the following effects:
S The doors are unlocked.
S The turn signal bulbs flash twice.
S The control module is disarmed.
Pressing the LOCK button has the following effects:
S The doors are locked.
S The turn signal bulbs flash once.
S The control module is armed.
The transmitter has a replaceable battery. The battery is
designed to last at least two years before replacement is
necessary.
SECURITY INDICATOR
There is a security indicator on the instrument panel. After
the LOCK button of the transmitter is pressed, the module
is placed in the armed mode, and the security indicator
flashes. The security indicator turns ON for 0.1 second
and OFF for 0.7 second. It then flashes at that frequency
until the control module/receiver is disarmed.
INTRUSION SENSING
The anti–theft function is armed if the transmitter sends
the LOCK message to the control module/receiver when
the ignition is OFF. When the hood, door, or trunk is
opened, the hood open, door contact, or trunk open switch
sends a ”ground” signal to the control module/receiver.
Unless the control module/receiver is disarmed, the siren
will be activated when the ”ground” signal is received from
the trunk open, hood open, or door contact switches.
The following actions disarm the anti–theft system:
S An UNLOCK message is received from the trans-
mitter.
S Key operation is detected by the tamper switches.
(The tamper switches are operated by the lock cyl-
inders in the front doors and trunk.)
The alarm will also be activated if the control module/re-
ceiver detects voltage from the ignition before either of the
following conditions occur:
S An UNLOCK message is received from the trans-
mitter.
S Key operation is indicated by the tamper switches.
SIREN (GENERAL ONLY)
The remote keyless entry system is armed when the
LOCK message is received from the transmitter when the
ignition is OFF. When the system is armed, it will activate
the siren and flash the turn signals for 28 seconds if any
of the following conditions occur:
S Close all the windows.
S Turn the ignition key to LOCK and remove the key.
S Have all passengers get out of the vehicle.
S Close all doors, the hood and the turnk lid.
S The control module/receiver detects ignition voltage
while the system is armed.
The siren will not operate if any of the following conditions
occur after the system has been armed:
S The door is opened with the key.
S The trunk is opened with the key.
S The UNLOCK or LOCK button on the remote trans-
mitter is pressed within 2 seconds after the siren is
activated.
VEHICLE LOCATOR
The remote keyless entry system assists the driver in lo-
cating the vehicle. When the vehicle is unlocked with the
remote control, the turn signals flash twice to indicate the
location of the vehicle. The duration of the flashes and the

1–2 GENERAL INFORMATIONNUBIRA/LACETTI
1. GENERAL INSTRUCTION
This publication is designed to help you the body repair
technician with your specialized work. Vehicle bodywork
has changed a great deal over the years. As vehicles
have developed technically, vehicle bodywork has also
had to meet new requirements with design, changes to
reconcile apparently conflicting demands to name just a
few examples:
S strength and safety ; low weight
S spaciousness ; good aerodynamices
S high quality ; low price
.
The durability and ease of repair of the bodywork also
plays an important part.
.
Nowadays, the use of highly automated production
equipment makes it possible to maintain the tightest
tolerances and thus ensure a high level of quality.
.
When bodywork is damaged, the customer rightly ex-
pects it to be expertly repaired to the same quality stan-
dards.
.
At the same time, for his safety, the customer expects
you to have comprehensive knowledge of materials,
measuring and straightening methods, possible distor-
tion, optimum corrosion prevention and much more be-
sides.
.
This publication is designed to help you update your
knowledge and give you an idea of what you require to
rectify moderate or severe accident damage, for your
own safety and for the satisfaction of your customers.
2. IMPORTANT SAFETY NOTICE
2–1. BEFORE BEGINNING WORK
S Disconnect the battery to reduce the possibility of fire
caused by electrical shorts.
S Check for fuel leaks and repair as necessary.
S Remove the fuel tank and/or fuel lines if welding equip-
ment is to be used near the fuel system.
S Before welding, sanding or cutting, protect carpets and
seats with fire–proof covers.
S Follow standard safety practices when using toxic or
flammable liquids.
S Use standard safety equipment when spraying paint,
welding, cutting, sanding or grinding. Standard safety
equipment includes.
S Respirator and filter masks: Designed to filter out toxic
fumes, mist, dust or other airborn particles. Use a respi-
rator or filter mask designed to protect you from the haz-
ards of the particular job; some respirators, for example,
are designed to filter out only dust and airborn particles,
not toxic fumes.
S Safety goggles or glasses: Designed to protect your
eyes from projectiles, dust particles or splashing liquid.
S Gloves: Rubber gloves protect against corrosive chemi-
cals. Welding gloves protect against burns and abra-
sions caused by welding, sanding or grinding.
S Safety shoes: Non–slip soles protect against slipping.
Metal toe inserts protect against falling objects.
S Ear plugs: Protect eardrums from harmful noise levels.
.
2–2. DURING WORK
S Do not smoke while working near the fuel system.
S Deposit gas or solvent–soaked shop towels in an ap-
proved container.
S Brake lining contains asbestos, which can cause cancer.
Do not use an air hose to blow off brake assemblies: use
only an approved vacuum cleaner, and wear an ap-
proved filter mask or respirator.
S Always attach a safety cable when using a hydraulic ram
or a frame straightening table: do not stand in direct line
with the chains used on such equipment.
