HOOD AJAR SWITCH
DESCRIPTION
The hood ajar switch is a self-adjusting, normally
closed, single pole, double throw momentary switch
that is used only on vehicles built for sale in certain
international markets where it is required equipment
(Fig. 3). The mounting bracket is fastened to the left
inner fender. A molded plastic striker with three inte-
gral retainers is secured to the underside of the hood
panel inner reinforcement to actuate the switch
plunger as the hood panel is closed.The switchreceives a path to ground through the left inner
fender shield in the engine compartment.
The hood ajar switch adjusts itself as the striker
pushes the switch body down through the switch
when the hood panel is closed after the initial instal-
lation. This self-adjustment feature is only functional
the first time the hood is closed following installa-
tion. If the switch requires adjustment following the
initial installation, the switch must be replaced.
OPERATION
The normally closed hood ajar switch is normally
held open when the hood panel is closed and latched.
When the hood is opened, the switch plunger extends
from the switch body and the switch contacts are
closed. The hood ajar switch is connected in series
between ground and the hood ajar switch sense input
of the Body Control Module (BCM). The BCM uses
an internal resistor pull up to monitor the state of
the hood ajar switch contacts. The hood ajar switch
can be diagnosed using conventional diagnostic tools
and methods.
DIAGNOSIS AND TESTING - HOOD AJAR
SWITCH
The diagnosis found here addresses an inoperative
hood ajar switch. If the problem being diagnosed is
related to hood ajar switch accuracy, be certain to
confirm that the problem is not an improperly
adjusted hood ajar switch. If no hood ajar switch
adjustment problem is found, the following procedure
will help to locate a short or open in the hood ajar
switch circuit. Refer to the appropriate wiring infor-
mation.

cluster circuitry that controls the lamp, (Refer to 8 -
ELECTRICAL/INSTRUMENT CLUSTER - DIAGNO-
SIS AND TESTING). If the instrument cluster turns
on the SKIS indicator lamp after the bulb test, either
solid or flashing, it indicates that a SKIS malfunction
has occurred or that the SKIS is inoperative. For
proper diagnosis of the SKIS, the PCI data bus, or
the message inputs to the instrument cluster that
control the SKIS indicator lamp, a DRBIIItscan tool
and the appropriate diagnostic information are
required.
TRANSPONDER KEY
DESCRIPTION
Each ignition key used in the Sentry Key Immobi-
lizer System (SKIS) has an integral transponder chip
(Fig. 10). Ignition keys with this feature can be
readily identified by a gray rubber cap molded onto
the head of the key, while conventional ignition keys
have a black molded rubber cap. The transponder
chip is concealed beneath the molded rubber cap,
where it is molded into the head of the metal key.
Each new Sentry Key has a unique transponder iden-
tification code permanently programmed into it by
the manufacturer. The Sentry Key transponder if
faulty or damaged, must be replaced.
OPERATION
When the ignition switch is turned to the On posi-
tion, the Sentry Key Immobilizer Module (SKIM)communicates through its antenna with the Sentry
Key transponder using a Radio Frequency (RF) sig-
nal. The SKIM then waits for a RF response from the
transponder through the same antenna. The Sentry
Key transponder chip is within the range of the
SKIM transceiver antenna ring when it is inserted
into the ignition lock cylinder. The SKIM determines
whether a valid key is present in the ignition lock
cylinder based upon the response from the transpon-
der. If a valid key is detected, that fact is communi-
cated by the SKIM to the Powertrain Control Module
(PCM) over the Programmable Communications
Interface (PCI) data bus, and the PCM allows the
engine to continue running. If the PCM receives an
invalid key message, or receives no message from the
SKIM over the PCI data bus, the engine will be dis-
abled after about two seconds of operation. The Elec-
troMechanical Instrument Cluster (EMIC) will also
respond to the invalid key message on the PCI data
bus by flashing the SKIS indicator on and off.
Each Sentry Key has a unique transponder identi-
fication code permanently programmed into it by the
manufacturer. Likewise, the SKIM has a unique
Secret Key code programmed into it by the manufac-
turer. When a Sentry Key is programmed into the
memory of the SKIM, the SKIM stores the transpon-
der identification code from the Sentry Key, and the
Sentry Key learns the Secret Key code from the
SKIM. Once the Sentry Key learns the Secret Key
code of the SKIM, it is permanently stored in the
memory of the transponder. Therefore, once a Sentry
Key has been programmed to a particular vehicle, it
cannot be used on any other vehicle. (Refer to 8 -
ELECTRICAL/VEHICLE THEFT SECURITY -
STANDARD PROCEDURE - TRANSPONDER PRO-
GRAMMING).
VTSS INDICATOR
DESCRIPTION
The Vehicle Theft Security System (VTSS) indica-
tor consists of a red Light-Emitting Diode that is
mounted and integral to the automatic headlamp
light sensor photo diode unit, which is located on the
top of the instrument panel. The remainder of the
housing including the mount and the electrical con-
nection are concealed beneath the instrument panel
top cover.
The VTSS indicator cannot be adjusted or repaired
the entire automatic headlamp light sensor/VTSS
indicator must be replaced. (Refer to 8 - ELECTRI-

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.

WASHER FLUID LEVEL
SWITCH
DESCRIPTION
The washer fluid level switch is a single pole, sin-
gle throw reed-type switch mounted near the front of
the washer reservoir, forward of the two washer
pump/motors (Fig. 20). Only the molded plastic
switch mounting flange and connector receptacle are
visible when the switch is installed in the reservoir.A short nipple formation extends from the inner sur-
face of the switch mounting flange, and a barb on the
nipple near the switch mounting flange is press-fit
into a rubber grommet seal installed in the mounting
hole of the reservoir. A small plastic float pivots on
the end of a bracket that extends from the switch
nipple formation. Within the float is a small magnet,
which actuates the reed switch. The washer fluid
level switch cannot be adjusted or repaired. If faulty
or damaged, the switch must be replaced.
OPERATION
The washer fluid level switch uses a pivoting,
oblong float to monitor the level of the washer fluid
in the washer reservoir. The float contains a small
magnet. When the float pivots, the changing proxim-
ity of its magnetic field will cause the contacts of the
small, stationary reed switch to open or close. When
the fluid level in the washer reservoir is at or above
the float level, the float moves to a vertical position
and the switch contacts open. When the fluid level in
the washer reservoir falls below the pivoting float,
the float moves to a horizontal position and the
switch contacts close. The switch is connected to the
vehicle electrical system through a dedicated take
out and connector of the left headlamp and dash wire
harness. The switch receives a five volt reference sig-
nal from the Body Control Module (BCM) through
the washer fluid switch output circuit. The switch is
grounded at all times through another take out of
the left headlamp and dash wire harness with a sin-
gle eyelet terminal connector that is secured under a
ground screw near the top of the left front fender
inner shield in the engine compartment.
When the switch closes, the BCM senses the volt-
age change on the circuit. The BCM is programmed
to send low washer fluid messages to the Electronic
Vehicle Information Center (EVIC) over the Program-
mable Communications Interface (PCI) data bus. The
EVIC is programmed to respond to this message by
displaying the Washer Fluid Low warning and send-
ing a chime request message back to the BCM over
the PCI data bus. Then the BCM generates an audi-
ble chime tone warning. A resistor within the washer
fluid level switch allows the BCM to monitor and
diagnose this circuit. The BCM will store a Diagnos-
tic Trouble Code (DTC) for any fault that it detects.
For retrieval of this fault information and further
diagnosis of the washer fluid level switch, the BCM,
the EVIC, the PCI data bus, the BCM message out-
puts to the EVIC that control the Low Washer Fluid
indicator, or the EVIC message outputs to the BCM
that control chime service, a DRBIIItscan tool and
the appropriate diagnostic information are required.

after cleaning the wiper blade and the glass, the
wiper blade fails to clear the glass without smearing,
streaking, chattering, hazing, or beading, replace the
wiper blade. Also, if a wiper blade is damaged or if
the squeegee rubber is damaged or deteriorated,
replace the wiper blade with a new unit. Do not
attempt to repair a wiper blade that is damaged.
WASHER SYSTEM
The washer system components should be
inspected periodically, not just when washer perfor-
mance problems are experienced. This inspection
should include the following points:
(1) Check for ice or other foreign material in the
washer reservoir. If contaminated, clean and flush
the washer system. (Refer to 8 - ELECTRICAL/
REAR WIPERS/WASHERS - CLEANING).
(2) Inspect the washer plumbing for pinched, leak-
ing, deteriorated, or incorrectly routed hoses and
damaged or disconnected hose fittings. Replace dam-
aged or deteriorated hoses and hose fittings. Leaking
washer hoses can sometimes be repaired by cutting
the hose at the leak and splicing it back togetherusing an in-line connector fitting. Similarly, sections
of deteriorated hose can be cut out and replaced by
splicing in new sections of hose using in-line connec-
tor fittings. Whenever routing a washer hose or a
wire harness containing a washer hose, it must be
routed away from hot, sharp, or moving parts. Also,
sharp bends that might pinch the washer hose must
be avoided.
REAR WASHER HOSES/TUBES
DESCRIPTION
The rear washer plumbing consists of small diam-
eter rubber hoses and molded plastic inline connector
fittings (Fig. 2). The washer reservoir hose is con-
nected to the barbed outlet nipple of the rear washer
pump/motor unit below the left front wheel house
extension and routed up the washer reservoir filler
neck to the engine compartment. Just rearward of
the washer reservoir filler neck in the engine com-
partment, an inline connector with barbed nipples
joins the reservoir hose to the engine compartment
hose. The engine compartment hose is routed along
the top of the left front fender wheel house to the
dash panel. The engine compartment hose passes
through a hole with a rubber grommet in the dash
panel into the passenger compartment. Below the
instrument panel in the passenger compartment near
the left cowl side inner panel, another inline connec-
tor joins the engine compartment hose to the A-pillar
hose. The A-pillar hose is routed up the left A-pillar
to the headliner. At the headliner, an inline connector
joins the A-pillar hose to the headliner hose. The
headliner hose is routed above the headliner and

REAR WASHER PUMP/MOTOR
DESCRIPTION
The rear washer pump/motor unit is located on the
outboard side and near the rear of the washer reser-
voir, between the left front inner and outer fender
panels (Fig. 5). A small permanently lubricated and
sealed electric motor is coupled to the rotor-type
washer pump. A seal flange with a large barbed inlet
nipple on the pump housing passes through a rubber
grommet seal installed in one of two dedicatedmounting holes near the bottom of the washer reser-
voir. The rear washer pump/motor unit is always
mounted in the higher pump mounting hole of the
reservoir. A smaller barbed outlet nipple on the pump
housing connects the unit to the rear washer hose.
The washer pump/motor unit is retained on the res-
ervoir by the interference fit between the barbed
pump inlet nipple and the grommet seal, which is a
light press fit. An integral electrical connector recep-
tacle is located on the top of the motor housing. The
rear washer pump/motor unit cannot be repaired. If
faulty or damaged, the entire washer pump/motor
unit must be replaced.
OPERATION
The rear washer pump/motor unit is connected to
the vehicle electrical system through a single take
out and two-cavity connector of the left headlamp
and dash wire harness. The washer pump/motor is
grounded at all times through a take out of the left
headlamp and dash wire harness with a single eyelet
terminal connector that is secured under a ground
screw to the top of the left inner fender shield in the
engine compartment. The rear washer pump/motor
receives battery current on a fused ignition switch
output (run-acc) circuit through the closed contacts of
the momentary rear washer switch within the right
multi-function switch only when the switch control
stalk is pushed towards the instrument panel.
Washer fluid is gravity-fed from the washer reservoir
to the inlet side of the washer pump. When the pump
motor is energized, the rotor-type pump pressurizes
