FRAME AND UNDERBODY 9N–3
DAEWOO M-150 BL2
REPAIR INSTRUCTIONS
ON–VEHICLE SERVICE
ALIGNMENT CHECKING
An accurate method of determining the alignment of the
underbody uses a measuring tram gauge. The tram
gauge set used to perform the recommended measuring
checks must include a vertical pointer able to reach
457 mm (18 inches).
Two types of measurements can be made with a tram
gauge: direct point-to-point measurements and mea-
surements calculated on a horizontal plane (datum line)
parallel to the underbody. Point-to-point measurements
are generally taken on steering and suspension engine
compartment parts and simply require the vertical point-
ers to be set equally.
For horizontal plane measurements, the vertical pointers
must be set as specified for each point to be measured.
Dimensions-to-gauge holes are measured to the center
of the holes and flush to the adjacent surface metal un-
less otherwise specified. It is recommended that the di-
agonal dimensions to the cross-body be checked on
both sides in order to verify the dimensional accuracy of
the vehicle underbody.
FLOOR PAN INSULATORS
The floor pan insulators have been designed for the
higher floor pan temperatures that result from the use
of the catalytic converter in the exhaust system. There-
fore, when servicing a vehicle, it is essential that any in-sulators that may have been disturbed or removed be
reinstalled in the original sequence and location. Also, if
an insulator needs to be replaced, use only the insula-
tion specified for that location on the floor pan.
When servicing or replacing interior insulators, observe
the following instructions.
Install the insulators in the original position and se-
quence. Butt the pieces together in order to avoid
gapping or overlapping.
If it is necessary to replace an insulator, use only the
specified insulation.
Use the original part to determine the amount of re-
placement material required and as a template for
cutting and fitting the new piece to the floor pan.
When installing the insulator, do not enlarge any cut-
outs or holes that are used for the attachment of interi-
or parts such as the instrument panel or the floor
console.
Route the cross-body harness for interior parts over
the floor pan insulators. Clip it in the original location.
Do not apply spray-on deadeners or trim adhesives to
the top of the floor pan at the area directly over the
catalytic converter or the muffler.
Any insulator service repair or replacement should be
the same thickness, size, and location as the original
installation in the vehicle.

9T–2 REMOTE KEYLESS ENTRY AND ANTI-THEFT SYSTEM
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
REMOTE KEYLESS ENTRY AND
ANTI-THEFT SYSTEM
The remote keyless entry and anti-theft system can per-
form the following functions:
Remotely lock and unlock the vehicle doors with a
hand-held high-frequency transmitter.
Sense intrusion into the vehicle through the doors,
the tailgate, or the hood.
Activate a warning to signal an intrusion.
Help the driver find the vehicle in a parking area.
Automatically re-lock the doors if a door or the trunk is
not opened within 30 seconds after the vehicle has
been unlocked by the remote keyless entry.
Communicate serial data to a scan tool to help diag-
nose system faults.
The remote keyless entry and anti-theft system consists
of the following components:
Keyless entry and anti-theft control module/receiver.
Security indicator.
Tailgate open switch.
Door open switches.
Central locking unit.
Flashing turn signal lamps.
Siren.
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 transmit-
ter 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
button which only function when the ignition is OFF.
Pressing the UNLOCK button has the following effects:
The doors are unlocked.
The turn signal lamps flash twice.
The control module is disarmed.
Pressing the LOCK button has the following effects:
The doors are locked.
The turn signal lamps flash once.
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. Af-
ter 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 1/8
second and OFF for 7/8 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, the door, or the tailgate is opened, the
hood open switch, the door open switch, or the tailgate
open switch will change its input to ground. The alarm
will be activated if the hood open sensor, the door open
sensor, or the tailgate open sensor changes its input to
ground before either of the following conditions occurs:
An UNLOCK message is received from the transmit-
ter.
SIREN
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 ac-
tivate the siren and flash the turn signals for 28 seconds
if any of the following conditions occurs:
A door is opened (front door open switch input is
changed to ground).
The tailgate is opened (tailgate open switch input is
changed to ground).
The hood is opened while the anti-theft system is
armed (hood open switch input is changed to
ground).
The siren is disarmed when any of the following condi-
tions occurs:
The ignition switch is turned ON with the key.
The UNLOCK button or the LOCK button on the re-
mote transmitter is pressed.
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 length of time between flashes is used to indi-
cate certain vehicle conditions. Refer to “Fault or Alarm
Indication” in this section.
9T–12 IMMOBILIZER ANTI-THEFT SYSTEM
DAEWOO M–150 BL2
3. If the ECM doesn’t receive a response message with-
in a defined time from beginning of the release time
period or the ECM receives a no release answer
→ the ECM enters the blocked state, which causes the
activation of the immobilization actions of the engine.
The inactive state of the Immobilizer (valid key/invalid
key) ends with turning off the ignition.
SECURITY INDICATOR
There is a security indicator on the instrument panel.
Status LED
An external LED displays the immobilizer system status.
The immobilizer contains the LED driver hardware for di-
rect connection of one LED.
