The ITM microprocessor continuously monitors
inputs from its on-board motion sensor as well as
inputs from the BCM and the alarm siren module.
The ITM motion sensor transmits ultrasonic signals
into the vehicle cabin through a transmit transducer,
then listens to the returning signals as the bounce off
of objects in the vehicle interior. If an object is mov-
ing in the interior, a detection circuit in the ITM
senses this movement through the modulation of the
returning ultrasonic signals that occurs due to the
Doppler effect. The motion detect function of the ITM
can be disabled by depressing the ªLockº button on
the Remote Keyless Entry (RKE) transmitter three
times within fifteen seconds, while the security indi-
cator is still flashing rapidly or by cycling the key in
the driver door cylinder from the center to the lock
position. The ITM will signal the alarm siren module
to provide a single siren ªchirpº as an audible confir-
mation that the motion sensor function has been dis-
abled.
If movement is detected, the ITM sends an mes-
sage to the BCM over the PCI data bus to flash the
exterior lighting and send a message to the alarm
siren module over a dedicated serial bus line to
sound the siren. When the BCM detects a breach in
the perimeter protection through a door, tailgate,
flip-up glass, or hood ajar switch input, it sends an
message to the ITM and the ITM sends an message
to the BCM over the PCI data bus to flash the exte-
rior lighting and send a message to the alarm siren
module over a dedicated serial bus line to sound the
siren. The ITM also monitors inputs from the alarm
siren module for siren battery or siren input/output
circuit tamper alerts, and siren battery condition
alerts, then sets active and stored Diagnostic Trouble
Codes (DTC) for any monitored system faults it
detects. An active fault only remains for the current
ignition switch cycle, while a stored fault causes a
DTC to be stored in memory by the ITM. If a fault
does not reoccur for fifty ignition cycles, the ITM will
automatically erase the stored DTC.
The ITM is connected to the vehicle electrical sys-
tem through the overhead wire harness. The ITM
receives battery voltage on a B(+) circuit through a
fuse in the Junction Block (JB), and is grounded to
the chassis at G303. These connections allow the
ITM to remain operational, regardless of the ignition
switch position. The hard wired inputs and outputs
for the ITM may be diagnosed and tested using con-
ventional diagnostic tools and procedures. However,
conventional diagnostic methods will not prove con-
clusive in the diagnosis of the ITM, the PCI data bus
network, or the electronic message inputs to and out-
puts from the ITM. The most reliable, efficient, and
accurate means to diagnose the ITM, the PCI data
bus network, and the message inputs to and outputsfrom the ITM requires the use of a DRBIIItscan
tool. Refer to the appropriate diagnostic information.

teen seconds. Below about sixteen kilometers-per-
hour (ten miles-per-hour) the delay times are
doubled, from about one second to about thirty-six
seconds.
AUTOMATIC WIPE MODE
On models equipped with the optional automatic
wiper system, when the control knob on the control
stalk of the right (wiper) multi-function switch is
moved to one of the five Auto sensitivity positions,
the BCM sends an electronic message to the Rain
Sensor Module (RSM) over the Programmable Com-
munications Interface (PCI) data bus network indi-
cating the selected position. The RSM monitors an
area within the wipe pattern of the windshield glass
for the accumulation of moisture. Based upon inter-
nal programming and the selected sensitivity level,
when sufficient moisture has accumulated the RSM
sends the appropriate electronic wipe command mes-
sages to the BCM over the PCI data bus and the
BCM operates the front wiper system accordingly. As
the sensitivity level is set higher, the RSM is more
sensitive to moisture accumulation and will send
wipe commands more frequently. The BCM logic is
also programmed to provide an immediate wipe cycle
each time the control knob on the control stalk of the
right multi-function switch is moved from a non-au-
tomatic wipe position to one of the five Auto sensitiv-
ity positions, and another immediate wipe cycle each
time the control knob is moved from a lower Auto
sensitivity position to a higher Auto sensitivity posi-
tion.
MIST WIPE MODE
When the control stalk of the right (wiper) multi-
function switch is moved to the momentary Mist
position, the BCM energizes the wiper on/off relay for
as long as the Mist switch is held closed, then de-en-
ergizes the relay when the state of the Mist switch
input changes to open. The BCM can operate the
front wiper motor in this mode for only one low speed
cycle at a time, or for an indefinite number of
sequential low speed cycles, depending upon how
long the Mist switch is held closed.
WASH MODE
When the control stalk of the right (wiper) multi-
function switch is moved to the momentary front
Wash position while the control knob is in the Low or
High positions, the circuitry within the switch directs
battery current to the front washer pump/motor unit.
This will cause the front washer pump/motor unit to
be energized for as long as the front Wash switch is
held closed, and to de-energize when the front Wash
switch is released. When the control stalk of the
right (wiper) multi-function switch is moved to the
momentary front Wash position while the controlknob is in one of the Delay interval or Auto sensitiv-
ity positions, the front washer pump/motor operation
is the same. However, the BCM energizes the wiper
on/off relay to override the selected delay interval or
auto sensitivity level and operate the front wiper
motor in a continuous low speed mode for as long as
the front Wash switch is held closed, then de-ener-
gizes the relay and reverts to the selected delay mode
interval or auto sensitivity level several wipe cycles
after the front Wash switch is released. The BCM
detects the front Wash switch state through a hard
wired washer pump motor switch output circuit input
from the right multi-function switch.
WIPE-AFTER-WASH MODE
When the control stalk of the right (wiper) multi-
function switch is moved to the momentary front
Wash position while the control knob is in the Off
position, the BCM detects that switch state through
a hard wired washer pump motor switch output cir-
cuit input from the right multi-function switch. The
BCM responds to this input by energizing the wiper
on/off relay for as long as the Wash switch is held
closed, then de-energizes the relay several wipe
cycles after the front Wash switch is released. The
BCM monitors the changing state of the wiper motor
park switch through a hard wired front wiper park
switch sense circuit input. This input allows the
BCM to count the number of wipe cycles that occur
after the front Wash switch state changes to open,
and to determine the proper interval at which to de-
energize the wiper on/off relay to complete the wipe-
after-wash mode cycle.
DIAGNOSIS AND TESTING - FRONT WIPER &
WASHER SYSTEM
FRONT WIPER SYSTEM
If the front wiper motor operates, but the wipers
do not move on the windshield, replace the faulty
front wiper module. If the wipers operate, but chat-
ter, lift, or do not clear the glass, clean and inspect
the wiper system components as required. (Refer to 8
- ELECTRICAL/FRONT WIPERS/WASHERS -
INSPECTION) and (Refer to 8 - ELECTRICAL/
FRONT WIPERS/WASHERS - CLEANING). Refer to
the appropriate wiring information. The wiring infor-
mation includes wiring diagrams, proper wire and
connector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.
The hard wired circuits and components of the
front wiper and washer system may be diagnosed
and tested using conventional diagnostic tools and
procedures. However, conventional diagnostic meth-

ods may not prove conclusive in the diagnosis of the
Body Control Module (BCM), the Rain Sensor Mod-
ule (RSM), the Powertrain Control Module (PCM) or
the inputs to or outputs from these modules that con-
trol the various front wiper and washer system oper-
ating modes. The most reliable, efficient, and
accurate means to diagnose the BCM, the RSM, the
PCM or the BCM inputs and outputs related to the
various front wiper and washer system operating
modes requires the use of a DRBIIItscan tool. Refer
to the appropriate diagnostic information.

RIGHT MULTI-FUNCTION
SWITCH
DESCRIPTION
The right (wiper) multi-function switch is secured
to the right side of the multi-function switch mount-
ing housing at the top of the steering column, just
below the steering wheel (Fig. 16). The only visible
component of the right multi-function switch is the
control stalk that extends through a dedicated open-
ing in the right side of the steering column shrouds.
The remainder of the right multi-function switch is
concealed beneath the steering column shrouds. The
switch housing and its control stalk are constructed
of molded black plastic. A single connector receptacle
containing up to ten terminal pins is located on the
back of the switch housing and connects the switch
to the vehicle electrical system through a take out
and connector of the instrument panel wire harness.
The switch is secured to the multi-function switch
mounting housing near the top of the steering col-
umn by two screws.
There are two versions of the right multi-function
switch: one to support the standard equipment speed
sensitive intermittent front wiper system, and a sec-
ond to support the optional front automatic wiper
system. Each version of the right multi-function
switch control stalk has both white nomenclature
and International Control and Display Symbol icons
applied to it, which clearly identify its many func-
tions. The control stalk has a control knob on its end
with a flattened face to allow it to be easily rotated.
Just below the control knob is a knurled control
sleeve. The right multi-function switch is the primary
control for the front and rear wiper and washer sys-
tems, and contains switches and circuitry to provide
signals to the Body Control Module (BCM) and the
rear wiper module.
The right (wiper) multi-function switch cannot be
adjusted or repaired. If any function of the switch is
faulty, or if the switch is damaged, the entire switch
unit must be replaced.
The right (wiper) multi-function switch supports
the following functions and features:
²Automatic Front Wipe Mode- On models
equipped with the optional automatic wiper system,
the internal circuitry and hardware of the right
(wiper) multi-function switch control knob provide an
automatic front wipe mode with five sensitivity posi-
tions.
²Continuous Front Wipe Modes- The internal
circuitry and hardware of the right (wiper) multi-
function switch control knob provide two continuous
front wipe switch positions, low speed or high speed.

²Continuous Rear Wipe Mode- The internal
circuitry and hardware of the right (wiper) multi-
function switch control sleeve provides one continu-
ous rear wipe switch position.
²Front Washer Mode- The internal circuitry
and hardware of the right (wiper) multi-function
switch control stalk provide front washer system
operation.
²Front Wipe-After-Wash Mode- The internal
circuitry and hardware of the right (wiper) multi-
function switch control stalk provide a wipe-after-
wash mode.
²Front Wiper Mist Mode- The internal cir-
cuitry and hardware of the right (wiper) multi-func-
tion switch control stalk provide a front wiper system
mist mode.
²Intermittent Front Wipe Mode- The internal
circuitry and hardware of the right (wiper) multi-
function switch control knob provide an intermittent
front wipe mode with five delay interval positions,
except on models equipped with the optional auto-
matic wiper system.
²Intermittent Rear Wipe Mode- The internal
circuitry and hardware of the right (wiper) multi-
function switch control ring provide one fixed inter-
val intermittent rear wipe mode switch position.
²Rear Washer Mode- The internal circuitry and
hardware of the right (wiper) multi-function switch
control stalk provide rear washer system operation.
OPERATION
The right (wiper) multi-function switch uses a com-
bination of resistor multiplexed and conventionally
switched outputs to control the many functions and
features it provides. The switch receives battery cur-
rent on a fused ignition switch output (run-acc) cir-
cuit from a fuse in the Junction Block (JB) whenever
the ignition switch is in the On or Accessory posi-
tions, and receives ground from the Body Control
Module (BCM) on a windshield wiper switch return
circuit. The right (wiper) multi-function switch may
be diagnosed using conventional diagnostic tools and
methods.
Following are descriptions of how the right (wiper)
multi-function switch control stalk operates to control
the functions and features it provides:
²Automatic Wipe Mode- On models equipped
with the optional automatic wiper system, the control
knob on the end of the right (wiper) multi-function
switch control stalk is rotated to one of five minor
intermediate detents to select the desired automatic
wipe sensitivity level. The control knob is rotated
rearward (counterclockwise) to reduce the sensitivity
(increase the interval between wipes), or forward
(clockwise) to increase the sensitivity (decrease the
interval between wipes). The right (wiper) multi-function switch provides a resistor multiplexed out-
put to the Body Control Module (BCM) on a
windshield wiper switch mux circuit. The BCM
responds by sending an electronic message to the
Rain Sensor Module (RSM) over the Programmable
Communications Interface (PCI) data bus indicating
the selected sensitivity level, and by operating the
front wiper system based upon electronic wipe com-
mands received from the RSM over the PCI data bus.
²Continuous Front Wipe Modes- The control
knob on the end of the right (wiper) multi-function
switch control stalk is rotated to an intermediate
detent that is one detent rearward (counterclockwise)
from the full forward (clockwise) detent to select the
low speed continuous front wiper mode, or to its full
forward (clockwise) detent to select the high speed
continuous front wiper mode. For the low speed
mode, the multi-function switch provides a resistor
multiplexed output to the Body Control Module
(BCM) on a windshield wiper switch mux circuit, and
the BCM responds by energizing the wiper on/off
relay in the Power Distribution Center (PDC) for the
front low speed continuous wipe mode. For the high
speed mode, the multi-function switch provides the
same resistor multiplexed output to the BCM on the
windshield wiper switch mux circuit as the low speed
mode, but also provides a ground output to the BCM
on a wiper high control circuit. The BCM responds to
these inputs by energizing the wiper on/off relay and
the wiper high/low relay in the PDC for the front
high speed continuous wipe mode.
²Continuous Rear Wipe Mode- The control
ring on the right (wiper) multi-function switch con-
trol stalk is rotated to the most forward (clockwise)
detent to select the continuous rear wiper mode. The
multi-function switch provides a battery current out-
put to the rear wiper motor on a rear wiper motor
control circuit to signal the rear wiper module to
operate the rear wiper motor in the continuous wipe
mode.
²Front Washer Mode- The control stalk of the
right (wiper) multi-function switch is pulled toward
the steering wheel to momentarily activate the front
washer pump/motor in the front washer mode. The
front washer pump will continue to operate in the
front washer mode until the control stalk is released.
The right (wiper) multi-function switch provides a
battery current output on a washer pump motor
switch output circuit to energize the front washer
pump in the front washer mode.
²Front Wiper Mist Mode- The control stalk of
the right (wiper) multi-function switch is pushed
towards the floor to momentarily activate the front
wiper motor in the mist mode. The front wiper motor
will continue to operate in the mist mode until the
control stalk is released. The right (wiper) multi-
