BUS FAILURE MESSAGE
Odometer Displays “No Bus” - The Mechanical
Instrument Cluster (MIC) cannot communicate
over the bus and does not know why.
3.15
VEHICLE THEFT SECURITY SYSTEM
This passive system is designed to protect against
vehicle theft. The vehicle theft security system
(VTSS) is part of the body control module (BCM),
which monitors vehicle doors and the ignition for
unauthorized operation. The alarm activates by
sounding the horn, flashing the headlamps, cour-
tesy lamps, and the VTSS indicator lamp. Passive
arming occurs upon normal vehicle exit by turning
the ignition off, opening the driver’s door, locking
the doors with the power lock, and closing the
driver’s door or locking the doors with RKE. Manual
arming occurs by using the key to lock the doors
after closing them. The indicator lamp in the instru-
ment cluster will flash for 15 seconds, showing that
arming is in progress. If no monitored systems are
activated during this period, the system will arm
and the indicator will flash at a slow rate. If the
indicator lamp remains steadily lit during the arm-
ing process, this can indicate a loss of decklid
cylinder lock switch. When something triggers the
alarm, the system will signal the headlamps, cour-
tesy lamps, and horn for about 3 minutes, then
headlamps for an additional 15 minutes if the
offending input is still present.
For complaints about the Theft Alarm going off on
its own use the DRBIII
t and select “Body Com-
puter” then “Input/Output Display” and read the
“Last VTSS Cause” status.
Tamper Alert - The VTSS indicator lamp will
flash twice quickly and the horn will chirp three
times when the system is disarmed to indicate a
tamper condition has occurred.
Manual Override - The system will not arm if the
doors are locked using the manual lock control (by
hand) or if the locks are actuated by an inside
occupant after the door is closed.
To verify the system, proceed as follows:
1. Open the driver’s door.
2. Remove the ignition key (but keep it in hand).
3. Lock the doors with the power lock switch or the
RKE.
4. Close the driver’s door.
NOTE: After the doors are closed, locking the
doors with RKE will also arm the system.
NOTE: If the VTSS indicator lamp flashed, the
system is operational and verified. If not, there may
be a problem with the system.
Arming/Disarming- Active arming occurs when
the remote keyless entry transmitter is used to lock
the vehicle doors, whether the doors are open or
closed. If one or more doors are open the arming
sequence is completed only after all doors are
closed.
Passive disarming occurs upon normal vehicle
entry (unlocking front door with the key). This
disarming also will halt the alarm once it has been
activated.
17
GENERAL INFORMATION
Active disarming occurs when the remote keyless
entry transmitter is used to unlock the vehicle
doors. This disarming also will halt the alarm once
it has been activated.
NOTE: A Powertrain Control Module from a
vehicle equipped with a vehicle theft security sys-
tem cannot be used in a vehicle that is not equipped
with a vehicle theft security system. If the VTSS
indicator lamp comes on after ignition ON and stays
on, the PCI bus communication with the Power-
train Control Module possibly has been lost.
3.16
WIPER SYSTEM
The wiper system provides the driver with the
normal wiper (low and high speeds), intermittent
wipe, and wipe after wash. The driver selects the
wiper function via the resistive multiplexed stalk
switch mounted on the steering column. The BCM
uses the input signal from the wiper stalk switch,
wiper motor park switch, and the washer switch to
control the wiper system. The Body Control Module
(BCM) then controls the relays and timing func-
tions to provide the driver selected features.
3.16.1
SYSTEM FEATURES
Speed Sensitive Intermittent Wipe Mode
There are 6 individual delay times with a mini-
mum delay of 1/2 second to a maximum of 18
seconds. When the vehicle speed is under 10 MPH
(16 KMH), the delay time is doubled providing a
range of 1 second to 36 seconds.
Park after Ignition Off
Because the wiper relays are powered from the
battery the BCM can run the wipers to park after
the ignition is turned off.
Wipe after Wash
When the driver presses the wash button for over
1/2 second and then releases it, the wiper will
continue to run for 2 additional wipe cycles.
The wiper system utilizes the BCM to control the
on/off and hi/low relays from low and hi speed wiper
functions, intermittent wiper delay as the switch
position changes, pulse wipe, wipe after wash mode,
and wiper motor park functions. The BCM uses the
vehicle speed input to double the usual delay time
below 10 MPH (16 KMH).

DRBIII
T DOES NOT POWER UP
(BLANK SCREEN)
If the LED’s do not light or no sound is emitted at
start up, check for loose cable connections or a bad
cable. Check the vehicle battery voltage (data link
connector cavity 16). A minimum of 11 volts is
required to adequately power the DRBIII
t. Check
for proper grounds at DLC cavities 4 and 5.
If all connections are proper between theDRBIII
t
and the vehicle or other devices, and the vehicle
battery is fully charged, and inoperative DRBIII
t
may be the result of faulty cable or vehicle wiring.

Set the parking brake and block the wheels before
testing or repairing the vehicle. It is especially
important to block the wheels on front-wheel drive
vehicles; the parking brake does not hold the drive
wheels.
When servicing a vehicle, always wear eye pro-
tection, and remove any metal jewelry such as
watchbands or bracelets that might make an inad-
vertent electrical contact.
When diagnosing a body system problem, it is
important to follow approved procedures where
applicable. These procedures can be found in this
General Information Section or in the service man-
ual procedures. Following these procedures is very
important to the safety of individuals performing
diagnostic tests.
4.2.2
VEHICLE PREPARATION FOR
TESTING
Make sure the vehicle being tested has a fully
charged battery. If it does not, false diagnostic codes
or error messages may occur.
4.2.3
SERVICING SUB ASSEMBLIES
Some components of the body system are in-
tended to be serviced in assembly only. Attempting
to remove or repair certain system sub-components
may result in personal injury and/or improper sys-
tem operation. Only those components with ap-
proved repair and installation procedures in the
service manual should be serviced.

WARNINGS
4.3.1
VEHICLE DAMAGE WARNINGS
Before disconnecting any control module, make
sure the ignition is “off”. Failure to do so could
damage the module.
When testing voltage or continuity at any control
module, use the terminal side (not the wire end) of
the connector. Do not probe a wire through the
insulation; this will damage it and eventually cause
it to fail because of corrosion.
Be careful when performing electrical tests so as
to prevent accidental shorting of terminals. Such
mistakes can damage fuses or components. Also, a
second DTC could be set, making diagnosis of the
original problem more difficult.
4.3.2
ROAD TEST COMPLAINT VEHICLE
Some complaints will require a test drive as part
of the repair verification procedure. The purpose of
the test drive is to try to duplicate the diagnostic
DTC or symptom condition.
WARNING: REASSEMBLE ALL COMPONENTS
