SWITCH
DESCRIPTION
There are two separate switch pods that operate
the speed control system. The steering-wheel-
mounted switches use multiplexed circuits to provide
inputs to the PCM for ON, OFF, RESUME, ACCEL-
ERATE, SET, DECEL and CANCEL modes. Refer to
the owner's manual for more information on speed
control switch functions and setting procedures.
The individual switches cannot be repaired. If one
switch fails, the entire switch module must be
replaced.
OPERATION
When speed control is selected by depressing the
ON, OFF switch, the PCM allows a set speed to be
stored in its RAM for speed control. To store a set
speed, depress the SET switch while the vehicle is
moving at a speed between approximately 35 and 85
mph. In order for the speed control to engage, the
brakes cannot be applied, nor can the gear selector
be indicating the transmission is in Park or Neutral.
The speed control can be disengaged manually by:
²Stepping on the brake pedal
²Depressing the OFF switch
²Depressing the CANCEL switch.
The speed control can be disengaged also by any of
the following conditions:
²An indication of Park or Neutral
²The VSS signal increases at a rate of 10 mph
per second (indicates that the co-efficient of friction
between the road surface and tires is extremely low)
²Depressing the clutch pedal.
²Excessive engine rpm (indicates that the trans-
mission may be in a low gear)

²The VSS signal decreases at a rate of 10 mph
per second (indicates that the vehicle may have
decelerated at an extremely high rate)
²If the actual speed is not within 20 mph of the
set speed
The previous disengagement conditions are pro-
grammed for added safety.
Once the speed control has been disengaged,
depressing the ACCEL switch restores the vehicle to
the target speed that was stored in the PCM's RAM.
NOTE: Depressing the OFF switch will erase the set
speed stored in the PCM's RAM.
If, while the speed control is engaged, the driver
wishes to increase vehicle speed, the PCM is pro-
grammed for an acceleration feature. With the
ACCEL switch held closed, the vehicle accelerates
slowly to the desired speed. The new target speed is
stored in the PCM's RAM when the ACCEL switch is
released. The PCM also has a9tap-up9feature in
which vehicle speed increases at a rate of approxi-
mately 2 mph for each momentary switch activation
of the ACCEL switch.
The PCM also provides a means to decelerate with-
out disengaging speed control. To decelerate from an
existing recorded target speed, depress and hold the
COAST switch until the desired speed is reached.
Then release the switch. The ON, OFF switch oper-
ates two components: the PCM's ON, OFF input, and
the battery voltage to the brake switch, which powers
the speed control servo.
Multiplexing
The PCM sends out 5 volts through a fixed resistor
and monitors the voltage change between the fixed
resistor and the switches. If none of the switches are
depressed, the PCM will measure 5 volts at the sen-
sor point (open circuit). If a switch with no resistor is
closed, the PCM will measure 0 volts (grounded cir-
cuit). Now, if a resistor is added to a switch, then the
PCM will measure some voltage proportional to the
size of the resistor. By adding a different resistor to
each switch, the PCM will see a different voltage
depending on which switch is pushed.
Another resistor has been added to the 'at rest cir-
cuit' causing the PCM to never see 5 volts. This was
done for diagnostic purposes. If the switch circuit
should open (bad connection), then the PCM will see
the 5 volts and know the circuit is bad. The PCM will
then set an open circuit fault.

electronic circuitry of the ITM which includes a
microprocessor, and an ultrasonic receive transducer.
A molded plastic connector receptacle containing six
terminal pins that is soldered to a small circuit board
and extends through a clearance hole in the left front
corner of the ITM housing, and an ultrasonic trans-
mit transducer housing extends from the center of
the right side of the ITM housing. Both the transmit
transducer on the right side of the module and the
receive transducer on the ITM circuit board are
aimed through two small round holes in the sight
shield of the trim cover. The ITM is connected to the
vehicle electrical system by a dedicated take out and
connector of the overhead wire harness that is inte-
gral to the headliner.
The ITM unit cannot be adjusted or repaired and,
if faulty or damaged, it must be replaced. The ITM is
serviced as a unit with the trim cover.
OPERATION
The microprocessor in the Intrusion Transceiver
Module (ITM) contains the motion sensor logic cir-
cuits and controls all of the features of the premium
version of the Vehicle Theft Alarm (VTA). The ITM
uses On-Board Diagnostics (OBD) and can communi-
cate with other electronic modules in the vehicle as
well as with the DRBIIItscan tool using the Pro-
grammable Communications Interface (PCI) data bus
network. This method of communication is used by
the ITM to communicate with the Body Control Mod-
ule (BCM) and for diagnosis and testing through the
16-way data link connector located on the driver side
lower edge of the instrument panel. The ITM also
communicates with the alarm siren over a dedicated
serial bus circuit.
The ITM microprocessor continuously monitors
inputs from its on-board motion sensor circuitry as
well as inputs from the BCM and the alarm siren
module. The on-board ITM motion sensor circuitry
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 moving 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 indicator is still flashing
rapidly. 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 elec-
tronic message to the BCM over the PCI data bus toflash the exterior lighting and sends an electronic
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 electronic message to the ITM and
the ITM sends an electronic message to the BCM
over the PCI data bus to flash the exterior lighting
and sends an electronic 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 recur for fifty ignition cycles, the ITM will
automatically erase the stored DTC.
The ITM is connected to the vehicle electrical sys-
tem through a dedicated take out and connector of
the overhead wire harness. The ITM receives battery
current on a fused B(+) circuit through a fuse in the
Junction Block (JB), and receives ground through a
ground circuit and take out of the body wire harness.
This ground take out has a single eyelet terminal
connector that is secured by a ground screw to the
base of the left D-pillar behind the quarter trim
panel. 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 conventional diagnos-
tic tools and procedures. However, conventional diag-
nostic methods will not prove conclusive in the
diagnosis of the ITM, the PCI data bus network, or
the electronic message inputs to and outputs from
the ITM. The most reliable, efficient, and accurate
means to diagnose the ITM, the PCI data bus net-
work, and the electronic message inputs to and out-
puts from the ITM requires the use of a DRBIIIt
scan tool. Refer to the appropriate diagnostic infor-
mation.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) While pulling downward lightly on either rear
corner of the Intrusion Transceiver Module (ITM)
trim cover, insert a small thin-bladed screwdriver

control stalk to a detent position selects the Off,
Delay, or On rear wiper system operating modes.
Rotating the control ring on the control stalk to
either of two Wash positions actuates the momentary
rear washer system switch. The multi-function
switch provides hard wired outputs to the rear wiper
module and the washer pump/motor unit for all rear
wiper and washer system functions.
The rear wiper and washer system will only oper-
ate when the ignition switch is in the Accessory or
On positions, and the rear flip-up glass and tailgate
ajar switches are closed. Battery current is directed
from a fuse in the Junction Block (JB) to the multi-
function switch through a fused ignition switch out-
put (run-acc) circuit. The internal circuitry of the
right (wiper) control stalk of the multi-function
switch then provides battery current signals through
a rear wiper on driver circuit and a rear wiper inter-
mittent driver circuit to the rear wiper module and
to the Body Control Module (BCM). The BCM uses
these rear wiper system inputs as a signal to lock the
rear flip-up glass and the tailgate to prevent the rear
flip-up glass or tailgate from being opened for as long
as the rear wiper is operating. The multi-function
switch circuitry also uses this battery current and a
ground circuit input to directly control the operation
and direction of the reversible electric washer pump/
motor unit.
A separate fuse in the JB provides battery current
to the electronic control circuitry of the rear wiper
module through a fused B(+) circuit. The rear wiper
module uses this fused B(+) input to park the rear
wiper blade off of the rear flip-up glass if the ignition
switch is turned to the Off position while the rear
wiper is operating, or if the ignition switch is turned
to the Off position before the rear wiper blade has
parked. However, if the ignition switch is turned to
the Off position while the rear wiper is operating,
then turned back On, the rear wiper switch must be
cycled to the Off position and back to the On or
Delay position before the rear wiper will operate
again. In addition, the rear wiper module receives an
input from the rear flip-up glass ajar switch on a
flip-up glass ajar switch sense circuit, which prevents
the rear wiper from operating when the flip-up glass
is not closed or fully latched.
The hard wired circuits and components of the rear
wiper and washer system may be diagnosed and
tested using conventional diagnostic tools and proce-
dures. Following are paragraphs that briefly describe
the operation of each of the rear wiper and washer
system operating modes.
CONTINUOUS WIPE MODE When the On posi-
tion of the control ring on the right (wiper) control
stalk of the multi-function switch is selected, the
multi-function switch circuitry directs a battery cur-rent signal to the rear wiper module through the
rear wiper on driver circuit, causing the rear wiper to
cycle continuously at a fixed speed.
INTERMITTENT WIPE MODE When the Delay
position of the control ring on the right (wiper) con-
trol stalk of the multi-function switch is selected, the
multi-function switch circuitry directs a battery cur-
rent signal to the rear wiper module through the
rear wiper intermittent driver circuit, causing the
rear wiper to cycle intermittently at a fixed delay
interval.
WASH MODE When the momentary Wash (after
On) position of the control ring on the right (wiper)
control stalk of the multi-function switch is selected,
the multi-function switch circuitry directs both bat-
tery current and ground to the washer pump/motor
unit, and a battery current signal to be provided to
the rear wiper module through the rear wiper on
driver circuit. This will cause the washer pump/mo-
tor unit to be energized and the rear wiper to cycle
continuously at a fixed speed for as long as the rear
Wash switch is held closed.
WIPE-AFTER-WASH MODE When the momentary
Wash (before Off) position of the control ring on the
right (wiper) control stalk of the multi-function
switch is selected, the multi-function switch circuitry
directs both battery current and ground to the
washer pump/motor unit, and a battery current sig-
nal to be provided to the rear wiper module through
the rear wiper on driver circuit. This will cause the
washer pump/motor unit to be energized and the rear
wiper to cycle continuously at a fixed speed for as
long as the rear Wash switch is held closed. When
the control ring is released to the Off position, the
washer pump/motor is de-energized, but the circuitry
within the rear wiper module will provide several
additional wipe cycles to complete the wipe-after-
wash mode cycle.
DIAGNOSIS AND TESTING - REAR WIPER &
WASHER SYSTEM
REAR WIPER SYSTEM
The diagnosis found here addresses an electrically
inoperative rear wiper system. If the rear wiper
motor operates, but the wiper does not move on the
rear flip-up glass, inspect the mechanical connection
between the rear wiper arm and the rear wiper
motor output shaft. If OK, replace the faulty rear
wiper module. If the wiper operates, but chatters,
lifts, or does not clear the glass, clean and inspect
the rear wiper system components as required. (Refer
to 8 - ELECTRICAL/REAR WIPERS/WASHERS -
INSPECTION) and (Refer to 8 - ELECTRICAL/
REAR WIPERS/WASHERS - CLEANING). Refer to
the appropriate wiring information. The wiring infor-

(3) Raise the pivot block latch release tab until it
is perpendicular to the rear wiper blade superstruc-
ture (Fig. 14).
(4) Insert the hook formation on the tip of the
wiper arm through the window in the wiper blade
pivot block/latch unit.
(5) Slide the wiper blade pivot block/latch up into
the hook formation on the tip of the wiper arm until
the hook is firmly seated against the pivot block.
(6) Press the pivot block latch release tab down-
ward until it snaps into its locked position over the
top of the wiper arm.
(7) Gently lower the wiper arm and place the arm
support in the tailgate park ramp.
REAR WIPER MOTOR
DESCRIPTION
The rear wiper motor is concealed within the tail-
gate, below the rear flip-up glass opening and behind
the tailgate inner trim panel. The end of the motor
output shaft that protrudes through the tailgate
outer panel to drive the rear wiper arm and blade is
the only visible component of the rear wiper motor
(Fig. 15). A rubber gasket, a bezel, and a nut secure
and seal the motor output shaft to the tailgate outer
panel. A molded plastic nut cover snaps onto the
bezel to conceal the nut and improve appearance. An
integral connector receptacle connects the rear wipermotor to the vehicle electrical system through a ded-
icated take out and connector of the tailgate wire
harness. The rear wiper motor consists of the follow-
ing major components:
²Bracket- The rear wiper motor bracket consists
of a stamped steel mounting plate for the wiper
motor that is secured with screws through two rub-
ber insulators to the tailgate inner panel.
²Rear Wiper Module- The rear wiper motor
electronic controls are concealed beneath a molded
plastic cover and includes the rear wiper system elec-
tronic logic and rear wiper motor electronic controls.
²Motor- The permanent magnet rear wiper
motor is secured with screws to the rear wiper motor
bracket. The wiper motor includes an integral trans-
mission, and the motor output shaft.
The rear wiper motor cannot be adjusted or
repaired. If any component of the motor is faulty or
damaged, the entire rear wiper motor unit must be
replaced. The motor output shaft gasket, bezel, nut,
and nut cover are available for service replacement.
OPERATION
The rear wiper motor receives non-switched bat-
tery current through a fuse in the Junction Block
(JB) on a fused B(+) circuit and is connected to
ground at all times. The rear wiper motor operation
is controlled by the vehicle operator through battery
current signal inputs received by the rear wiper
motor electronic control module from the rear wiper
switch circuitry that is integral to the right (wiper)
control stalk of the multi-function switch on the
steering column. The module also receives an exter-
nal control input from the flip-up glass ajar switch
sense circuit. If the rear wiper module senses that
the flip-up glass is ajar, it will not allow the rear
wiper motor to operate.
The rear wiper module electronic control logic uses
these inputs, its internal inputs, and its program-
ming to provide a continuous wipe mode, an inter-
mittent wipe mode, a wipe-after-wash mode, and off-
the-glass wiper blade parking. The wiper blade
cycling is controlled by the internal electronic con-
trols of the module. The module controls current flow
to the wiper motor brushes and provides an elec-
tronic speed control that speeds the wiper blade near
the center of the glass, but slows the wiper blade
during directional reversals at each end of the wipe
pattern and during wiper blade off-the-glass parking
for quieter operation. The wiper motor transmission
converts the rotary output of the wiper motor to the
back and forth wiping motion of the rear wiper arm
and blade on the rear flip-up glass.
