DIAGNOSIS
TESTING REAR WINDOW
DEFOGGER GRID LINE
If it has been observed during use that a grid line is inop-
erative, the following procedure can be used to find the
break. If none of the grid lines is operating, a full system
diagnosis should be completed before attempting to repair
the grid lines.
1. Turn the ignition ON.
2. Turn the rear window defogger on.
3. From the inside of the vehicle, connect a voltmeter
to each end of a grid line. The voltmeter will indi-
cate battery voltage if the grid line is open.
Notice : Use care when touching the voltmeter leads to a
grid line. If the leads are roughly applied, the grid line may
be scratched, resulting in an open circuit.4. If a grid line is found to be open, move a voltmeter
lead from one side of the grid line and retest at a
point nearer to the other side of the window. Contin-
ue to retest, each time bringing one of the voltmeter
leads closer to the opposite side of the window
from where it was originally placed. The break in
the grid line is at the point where the voltmeter be-
gins reading 0 volts instead of battery voltage.
5. Use a marking crayon to lightly mark the break
point on the rear window. Mark the glass instead of
marking directly on the grid line, and make the
mark far enough from the grid line so that it can
easily be removed without disturbing the repair.
6. Use a grid line repair kit to fix the break in the grid
line. Refer to ”Rear Window Defogger Grid Line
Repair” in this section.

DOOR LOCK STRIKER ADJUSTMENT
(Front Door Shown, Rear Door Similar)
The door lock striker consists of a striker with two screws
that are threaded into a tapped, floating cage plate located
in the appropriate body pillar. This floating cage plate al-
lows the striker to be easily adjusted in and out or up and
down.
The door is secured in the closed position when the door
lock fork snaps over and engages the striker.
Notice : The door lock striker is an important attaching
part that can affect the performance of vital components
and systems. It can cause major repair expenses. If re-
placement becomes necessary, the door lock striker must
be replaced by one with the same part number or with an
equivalent. Do not use a replacement part of lesser quality
or of a substitute design. The specified torque values must
be used during reassembly to ensure the proper retention
of the part.
Up/Down or In/Out Adjustment
An adjustment of the striker in the up and down or in and
out directions may be necessary for a number of reasons:
S Vehicle frame damage as the result of a collision.
S Installation of new door weatherstripping.
S Customer complaints of excessive windnoise.
S Difficulty in opening or closing the door.
To adjust the door striker in an up and down or in and out
direction, perform the following procedure:
1. The door must be properly aligned.
2. Loosen the striker screws.
3. The floating cage plate can be moved slightly using
the ends of the striker screws. Move the floating
cage plate to the desired position.
4. If proper adjustment requires that the floating cage
plate be moved more than is possible, use an elec-
tric hand drill and a 3/8–inch rotary file bit with a flat
head to enlarge the body opening in the direction
required.
Notice : It is important to use a flat–tipped drill bit to pre-
vent damage to the tapped floating cage plate. The striker
screws and the tapped floating cage plate are important
attaching parts that could affect the performance of vital
components and systems.
5. Tighten the door lock striker screws to the correct
position.
Tighten
Tighten the door lock striker screws to 24 NSm (18 lb–
ft).

vidual units.
The one–piece formed headliner consists of a molded
substrate covered with a foam–backed cloth facing. The
one–piece construction requires that the headliner be ser-
viced as a complete assembly.

REMOTE KEYLESS ENTRY AND ANTI–THEFT SYSTEM 9T1 – 7
DAEWOO V–121 BL4
REMOTE KEYLESS ENTRY
TRANSMITTER PROGRAMMING
The Remote Keyless Entry System allows for the use of
as many as four(4) transmitters for each vehicle. Replace-
ment Remote Keyless Entry System Transmitters must
first be programmend to specific vehicle using the
Scan100 Secan tool.
This process is completed using serial data communica-
tion between the Scan 100 Scan tool and the Remote Key-
less Entry Control Unit and is the only method available for
programming Transmitters.
Notice : All Transmitters for a specific vehicle must be pro-
grammed at same time.
Notice : Once the programming function of the Remote
Keyless Entry System is activated, any Transmitter(exist-
ing or new) that is not programmed(or reprogrammed)
during the programming procedure will no longer operate
the Remote Keyless Entry System of that vehicle.
Notice : Ensure that the doors, hood and trunk/rear hatch
are closed prior to starting the programming procedure.
