DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
DOOR LOCK STRIKER
The front and the rear door lock strikers each consist of
a striker with two screws threaded into a floating cage
plate in the B-pillars and C-pillars. The door is secured in
the closed position when the door lock fork snaps over
and engages the striker.
CHILDPROOF REAR DOOR LOCK
The childproof rear door locks help prevent passengers,
especially children, from opening the rear doors of the
vehicle from the inside.
In order to activate these locks, move the levers of both
rear doors to the lock position. Then, close both doors.
Rear passengers will be unable to open the doors from
the inside of the vehicle.
In order to deactivate the childproof rear door lock, un-
lock the door from the inside of the vehicle and open the
door from the outside. Move the lever to the unlock posi-
tion. The rear door will now work normally.
POWER DOOR LOCKS
The power door locks use a solenoid that is contained in
each door lock assembly. The door locks are activatedby the actuator on the inside door handle or by the lock
cylinder on the driver door only. When the driver door is
locked or unlocked by the actuator or lock cylinder, all
doors are locked or unlocked accordingly.
POWER WINDOWS
The power windows are controlled by electrical switches
on the front door tirm and operated by a motor at each
window regulator. The windows are lowered by pressing
the switch and raised by pulling up on the switch. The
window will stop movement when the switch is released
or when the window is completely open or closed.
TAILGATE STRUT
This vehicle is equipped with the gas struts. The struts
support the tailgate suitably when opening the tailgate.
The strut contained the high pressure compressed gas.
Therefore, be careful not to take apart, puncture, apply
heat or fire bacause the strut may explode.

DOOR LOCK STRIKER ADJUSTMENT
Notice: The door lock striker is an important attaching
part that can affect the performance of vital components
and systems and can cause major repair expenses. If
replacement becomes necessary, the door lock striker
must be replaced by one with the same part number or
with an equivalent part if replacement becomes neces-
sary. Do not use a replacement part of lesser quality or
of a substitute design. The specified torque values must
be used during reassembly in order to ensure the proper
retention of the part.
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 allows the striker to be easily adjusted in or
out and up or down. The door is secured in the closed
position when the door lock fork snaps over and en-
gages the striker.
D19C575A
Fore/Aft Adjustment
1. The door must be properly aligned.
2. Close the door until the lock fork contacts the striker.
3. Stand next to the door opening and move the door
slowly in and out, just touching the striker each time.
D109C576
4. The alignment of the lock fork and the striker can be
easily seen. The lock fork should be perpendicular to
and fall near the middle of the striker. The lock fork
should fall near the middle of the striker between the
B-pillar and the end of the striker.

5. If a fore or aft adjustment is required, use the following
steps:

Remove the striker screws (1).

Remove the spacer in order to move the striker to-
ward the rear of the vehicle (2).

Add a 2 mm (0.08 inch) spacer in order to move
the striker toward the front of the vehicle.

Install the striker screws.
6. Perform the up/down or the in/out adjustment. Refer
to ‘‘Up/Down or In/Out Adjustment’’ in this section.
D109C574
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:
vehicle frame damage as the result of a collision, installa-
tion of new door weatherstripping, customer complaints
of excessive windnoise, or difficulty in opening or closing
the door. In order to adjust the door striker in an up and
down or in and out direction, perform the following proce-
dure:
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.
Notice: It is important to use a flat-end rotary file in or-
der not to damage the tapped floating cage plate. The
striker screws and the tapped floating cage plate are im-
portant attaching parts that could affect the performance
of vital components and systems.
4. If proper adjustment requires that the floating cage plate
be moved more than is possible, use an electric hand
drill and a 3/8- inch rotary file with a flat head in order to
enlarge the body opening in the direction required.
5. Tighten the striker screws to the correct position.

TAILGATE LOCK STRIKER
ADJUSTMENT
Notice: The tailgate lock striker is an important attaching
part that can affect the performance of vital components
and systems and can cause major repair expenses. If re-
placement becomes necessary, the tailgate lock striker
must be replaced by one with the same part number or
with an equivalent part if replacement becomes neces-
sary. Do not use a replacement part of lesser quality or of
a substitute design. The specified torque values must be
used during reassembly in order to ensure the proper
retention of the part.

ger seat. Passengers can use these handles to assist in
keeping their balance over rough roads or during sharp
turns.
COAT HOOK
The coat hook is fastened to the headliner above the
left-hand rear passenger seat for Left–Hand Drive or
right hand rear passenger seat for Right–Hand Drive.
This position has a coat hook in the place of a passenger
assist handle.

6. Turn the ignition OFF and ON again, but do not
crank or start the engine. The ECM will reset the
ECM ID code to match the new ID code that was
calculated and sent by the immobilizer control unit
when the ignition was first turned ON after the reset
command.
7. Return the system to the normal mode.
8. Turn OFF the ignition.
9. Turn ON the ignition.
10. Start the engine.
After reprogramming the ID code, the scan tool SYS-
TEM DIAGNOSIS command can verify that the ECM ID
code matches the immobilizer control unit ID code.
If the reprogramming procedure does not result in
matching ID codes, check the electrical connectors for
the serial data wire between the immobilizer control unit
and the ECM.
TRANSPONDER
Each valid ignition key has an internal transponder
which is a read /write transponder.
The transponder contains an implementation of a cryp-
to-algorithm with 96 bits of user configurable secret-key
contained in EEPROM and transmits data to the ICU by
modulating the amplitude of the electromagnetic field,
and receives data and commands in a similar way.
