INDICATORS
Indicators are located in various positions within
the EMIC and are all connected to the EMIC elec-
tronic circuit board. The ambient temperature indica-
tor (optional), brake indicator, brake wear indicator,
charging indicator, coolant low indicator, high beam
indicator, low fuel indicator, park brake indicator,
seatbelt indicator, turn signal indicators, and washer
fluid indicator operate based upon hard wired inputs
to the EMIC. The airbag (SRS) indicator is normally
controlled by a hard wired input from the Airbag
Control Module (ACM); however, if the EMIC sees an
abnormal or no input from the ACM, it will automat-
ically turn the airbag indicator On until the hard
wired input from the ACM has been restored. The
Malfunction Indicator Lamp (MIL) is normally con-
trolled by CAN data bus messages from the Engine
Control Module (ECM); however, if the EMIC loses
CAN data bus communication, the EMIC circuitry
will automatically turn the MIL on until CAN data
bus communication is restored. The EMIC uses CAN
data bus messages from the ECM, the ACM, and the
Controller Antilock Brake to control all of the
remaining indicators.
The various EMIC indicators are controlled by dif-
ferent strategies; some receive battery feed from the
EMIC circuitry and have a switched ground, while
others are grounded through the EMIC circuitry and
have a switched battery feed. However, all indicators
are completely controlled by the EMIC microproces-
sor based upon various hard wired and electronic
message inputs. Except for the indications provided
by the multi-function indicator Liquid Crystal Dis-
play (LCD) unit, all indicators are illuminated at a
fixed intensity, which is not affected by the selected
illumination intensity of the EMIC general illumina-
tion lamps.
The hard wired indicator inputs may be diagnosed
using conventional diagnostic methods. However,
proper testing of the EMIC circuitry and the CAN
bus message controlled indicators requires the use of
a diagnostic scan tool. Refer to the appropriate diag-
nostic information. Specific details of the operation
for each indicator may be found elsewhere in this
service information.
CLUSTER ILLUMINATION
The EMIC has several general illumination lamps
that are illuminated when the exterior lighting is
turned on with the multi-function switch. The illumi-
nation intensity of these lamps is adjusted by a dim-
ming level input received from the multi-function
indicator ª+º (plus) and ª±º (minus) switch push but-
tons that extend through the lower edge of the clus-
ter lens below the right end of the multi-function
indicator. When the exterior lighting is turned Off,
the display is illuminated at maximum brightness.
When the exterior lighting is turned On and thetransmission gear selector is in the Park position,
depressing the plus switch push button brightens the
display lighting, and depressing the minus switch
push button dims the display lighting. The EMIC
also provides a Pulse-Width Modulated (PWM) panel
lamps dimmer output that can be used to synchro-
nize the illumination lighting levels of external illu-
mination lamps (up to about 23 to 30 watts) with
that of the EMIC.
The hard wired multi-function switch input and
the EMIC panel lamps dimmer output may be diag-
nosed using conventional diagnostic methods. How-
ever, proper testing of the PWM control of the EMIC
and the electronic dimming level inputs from the
multi-function indicator push buttons requires the
use of a diagnostic scan tool. Refer to the appropriate
diagnostic information.

equipped, the ambient temperature indication can be
toggled with the clock indication on the right side of
the multi-function indicator Liquid Crystal Display
(LCD) located near the lower edge of the instrument
cluster, directly below the speedometer. The ambient
temperature indication consists of a numeric value
with a ª+º (plus) or ª2º (minus) prefix, and the unit
of measure is identified with the characters ªÉCº
(Canadian vehicles only) or ªÉFº (United States vehi-
cles only) located directly above the temperature
indication. The indications of the ambient tempera-
ture indicator are not visible when the LCD is not
illuminated. When illuminated the indications
appear as dark characters and icons silhouetted
against an amber field. When the exterior lighting is
turned Off, the display is illuminated at maximum
brightness. When the exterior lighting is turned On
the display illumination level can be adjusted in con-
cert with the cluster general illumination lighting
using the ª+º (plus) and ª2º (minus) multi-function
indicator push buttons. The ambient temperature
indicator is serviced as a unit with the instrument
cluster.
OPERATION
The optional ambient temperature indicator gives
an indication to the vehicle operator of the outside
air temperature. This indicator is controlled by the
instrument cluster microprocessor based upon cluster
programming and a hard wired input received by the
cluster from the ambient temperature sensor. The
ambient temperature indicator is completely con-
trolled by the instrument cluster logic circuit, and
that logic will allow this indicator to operate when-
ever the multi-function indicator Liquid Crystal Dis-
play (LCD) is activated. Therefore, the ambient
temperature indicator remains functional regardless
of the ignition switch position.
The vehicle operator can choose to have the ambi-
ent temperature indicator displayed instead of the
clock information, but the clock and ambient temper-
ature indicator cannot be displayed at the same time.
The clock or ambient temperature indicator display
option is selected using the multi-function indicator
clock switch on the instrument cluster circuit board.
This switch is actuated manually by depressing the
clock switch push button that extends through the
lower edge of the cluster lens below the left end of
the multi-function indicator. Actuating this switch
momentarily will toggle the display between the
clock and ambient temperature indicator modes.
Actuating this switch twice within about one second
will cause the display to toggle, but then automati-
cally revert to the originally selected mode after
about twenty seconds.
The ambient temperature sensor located below the
front bumper is a Negative Temperature Coefficient
(NTC) thermistor. The internal resistance of the sen-sor is reduced as the ambient temperature rises. The
instrument cluster continually monitors the resis-
tance through the sensor to determine the tempera-
ture value to be displayed. The current value is
displayed immediately after the LCD is activated.
The display value will remain static regardless of
decreases in the sensor resistance (temperature ris-
ing) below vehicle speeds of 10 to 15 kilometers-per-
hour (6 to 9 miles-per-hour). Decreases in the sensor
resistance above 15 kilometers-per-hour (9 miles-per-
hour) and increases the sensor resistance (tempera-
ture falling) regardless of vehicle speed are displayed
subject to a sixty second delay.
The ambient temperature sensor is connected to
the instrument cluster in series between the ambient
temperature sensor return and sense circuits. The
ambient temperature sensor and the return and
sense circuits to the instrument cluster can be diag-
nosed using conventional diagnostic tools and meth-
ods. For proper diagnosis of the instrument cluster
circuitry that controls the ambient temperature indi-
cator, a diagnostic scan tool is required. Refer to the
appropriate diagnostic information.BRAKE INDICATOR
DESCRIPTION
A brake indicator is standard equipment on all
instrument clusters. The brake indicator is located
near the lower edge of the instrument cluster, to the
left of the multi-function indicator display. In vehi-
cles built for the United States market, the brake
indicator consists of a stencil-like cutout of the word
ªBRAKEº in the opaque layer of the instrument clus-
ter overlay. In vehicles built for the Canadian mar-
ket, the brake indicator consists of the International
Control and Display Symbol icon for ªBrake Failureº
imprinted within a rectangular cutout in the opaque
layer of the instrument cluster overlay. In either
case, the dark outer layer of the overlay prevents the
indicator from being clearly visible when it is not
illuminated. A red Light Emitting Diode (LED)
behind the cutout in the opaque layer of the overlay
causes the ªBRAKEº text to appear in red, or the
icon to appear silhouetted against a red field through
the translucent outer layer of the overlay when the
indicator is illuminated from behind by the LED,
which is soldered onto the instrument cluster elec-
tronic circuit board. The brake indicator is serviced
as a unit with the instrument cluster.
OPERATION
The brake indicator gives an indication to the vehi-
cle operator when there are certain brake hydraulic
system malfunctions as indicated by a low brake
hydraulic fluid level condition, or when there is a
problem in the electronic brake force distribution
8J - 12 INSTRUMENT CLUSTERVA

(EBV) system. This indicator is controlled by a tran-
sistor on the instrument cluster circuit board based
upon cluster programming, electronic messages
received by the cluster from the Controller Antilock
Brake (CAB) over the Controller Area Network
(CAN) data bus, and a hard wired input from the
brake fluid level switch. The brake indicator Light
Emitting Diode (LED) is completely controlled by the
instrument cluster logic circuit, and that logic will
only allow this indicator to operate when the instru-
ment cluster detects that the ignition switch is in the
On position. Therefore, the LED will always be off
when the ignition switch is in any position except
On. The LED only illuminates when it is provided a
path to ground by the instrument cluster transistor.
The instrument cluster will turn on the brake indica-
tor for the following reasons:
²Bulb Test- Each time the ignition switch is
turned to the On position the brake indicator is illu-
minated by the instrument cluster for about two sec-
onds as a bulb test.
²Brake Fluid Level Switch Input- Each time
the cluster detects ground on the brake indicator sig-
nal circuit (brake fluid level switch closed = brake
fluid level low) while the ignition switch is in the On
position, the brake indicator is illuminated. The indi-
cator remains illuminated until the brake signal indi-
cator input to the cluster is an open circuit (brake
fluid level switch open = brake fluid level okay), or
until the ignition switch is turned to the Off position,
whichever occurs first.
²Electronic Brake Force Distribution (EBV)
Indicator Lamp-On Message- Each time the clus-
ter receives a EBV indicator lamp-on message from
the CAB, the indicator will be illuminated. The indi-
cator remains illuminated until the cluster receives a
lamp-off message from the CAB, or until the ignition
switch is turned to the Off position, whichever occurs
first.
The CAB continually monitors the EBV system cir-
cuits and sensors to decide whether the system is in
good operating condition. The CAB then sends the
proper lamp-on or lamp-off messages to the instru-
ment cluster. If the CAB sends a lamp-on message
after the bulb test, it indicates that the CAB has
detected a system malfunction and that the EBV sys-
tem has become inoperative. The CAB will store a
Diagnostic Trouble Code (DTC) for any malfunction it
detects.
The brake fluid level switch in the brake master
cylinder provides a hard wired ground input to the
instrument cluster circuitry through the brake indi-
cator signal circuit whenever the fluid level in the
brake master cylinder is low. The switch is connected
in parallel between ground and the instrument clus-
ter. The brake fluid level switch and the input circuit
to the instrument cluster can be diagnosed using con-
ventional diagnostic tools and methods. For properdiagnosis of the instrument cluster circuitry that con-
trols the brake indicator, a diagnostic scan tool is
required. Refer to the appropriate diagnostic infor-
mation.
BRAKE WEAR INDICATOR
DESCRIPTION
A brake wear indicator is standard equipment on
all instrument clusters. The brake wear indicator is
located near the lower edge of the instrument cluster,
to the left of the multi-function indicator display. The
brake wear indicator consists of the International
Control and Display Symbol icon for ªWorn Brake
Liningsº imprinted within a rectangular cutout in the
opaque layer of the instrument cluster overlay. The
dark outer layer of the overlay prevents the indicator
from being clearly visible when it is not illuminated.
An amber Light Emitting Diode (LED) behind the
cutout in the opaque layer of the overlay causes the
icon to appear silhouetted against an amber field
through the translucent outer layer of the overlay
when the indicator is illuminated from behind by the
LED, which is soldered onto the instrument cluster
electronic circuit board. The brake wear indicator is
serviced as a unit with the instrument cluster.
OPERATION
The brake wear indicator gives an indication to the
vehicle operator when the brake linings have reached
their wear limits. This indicator is controlled by a
transistor on the instrument cluster circuit board
based upon cluster programming and a hard wired
input from the four brake wear sensors, one at each
wheel. The brake wear indicator Light Emitting
Diode (LED) is completely controlled by the instru-
ment cluster logic circuit, and that logic will only
allow this indicator to operate when the instrument
cluster detects that the ignition switch is in the On
position. Therefore, the LED will always be off when
the ignition switch is in any position except On. The
LED only illuminates when it is provided a path to
ground by the instrument cluster transistor. The
instrument cluster will turn on the brake wear indi-
cator for the following reasons:
²Bulb Test- Each time the ignition switch is
turned to the On position the brake wear indicator is
illuminated by the instrument cluster for about two
seconds as a bulb test.
²Brake Wear Sensor Input- Each time the
cluster detects ground on the brake wear sense cir-
cuit (brake wear sensor closed = brake lining wear
limit exceeded) while the ignition switch is in the On
position, the brake wear indicator is illuminated. The
indicator remains illuminated until the brake wear
sense input to the cluster is an open circuit (brake
wear sensor open = brake lining wear within limits),

The ECM continually monitors the engine coolant
temperature sensor to determine when the glow
plugs need to be energized in their pre-heat operat-
ing mode. The ECM then sends the proper wait-to-
start lamp-on and lamp-off messages to the
instrument cluster. If the instrument cluster turns on
the indicator after the engine is started, it may indi-
cate that a malfunction has occurred and that the
engine glow control system requires service. The
ECM will store a Diagnostic Trouble Code (DTC) for
any malfunction it detects. For proper diagnosis of
the engine coolant temperature sensor, the engine
glow control system and circuits, the ECM, the CAN
data bus, or the electronic message inputs to the
instrument cluster that control the wait-to-start indi-
cator, a diagnostic scan tool is required. Refer to the
appropriate diagnostic information.
WASHER FLUID INDICATOR
DESCRIPTION
A washer fluid indicator is standard equipment on
all instrument clusters. However, this indicator is
only functional on vehicles equipped with an optional
washer fluid level switch integral to the washer
pump/motor unit on the washer reservoir. The
washer fluid indicator is located near the lower edge
of the instrument cluster, to the right of the multi-
function indicator display. The washer fluid indicator
consists of the International Control and Display
Symbol icon for ªWindshield Washer Fluidº imprinted
within a rectangular cutout in the opaque layer of
the instrument cluster overlay. The dark outer layer
of the overlay prevents the indicator from being
clearly visible when it is not illuminated. An amber
Light Emitting Diode (LED) behind the cutout in the
opaque layer of the overlay causes the icon to appear
silhouetted against an amber field through the trans-
lucent outer layer of the overlay when the indicator
is illuminated from behind by the LED, which is sol-
dered onto the instrument cluster electronic circuit
board. The washer fluid indicator is serviced as a
unit with the instrument cluster.
OPERATION
The washer fluid indicator gives an indication to
the vehicle operator that the fluid level in the washer
reservoir is low. This indicator is controlled by the
instrument cluster circuit board based upon cluster
programming and a hard wired input from the
optional washer fluid level switch that is integral to
the washer pump/motor unit. The washer fluid indi-
cator is completely controlled by the instrument clus-
ter logic circuit, and that logic will only allow this
indicator to operate when the instrument cluster
detects that the ignition switch is in the On position.
Therefore, the indicator will always be off when theignition switch is in any position except On. The indi-
cator only illuminates when it is switched to ground
by the instrument cluster circuitry. The instrument
cluster will turn on the washer fluid indicator for the
following reasons:
²Bulb Test- Each time the ignition switch is
turned to the On position the brake wear indicator is
illuminated by the instrument cluster for about two
seconds as a bulb test.
²Washer Fluid Level Switch Input- Each time
the cluster detects ground on the washer fluid switch
sense circuit (washer fluid level switch closed =
washer fluid level low) while the ignition switch is in
the On position, the washer fluid indicator is illumi-
nated. The indicator remains illuminated until the
washer fluid level switch input to the cluster is an
open circuit (washer fluid level switch open = washer
fluid level acceptable), or until the ignition switch is
turned to the Off position, whichever occurs first.
The instrument cluster continually monitors the
washer fluid level switch to determine the level of
the washer fluid. The instrument cluster logic applies
a delay strategy to this input to reduce the negative
effect that fluid sloshing within the reservoir can
have on reliable indicator operation. The washer
fluid level switch and circuit can be diagnosed using
conventional diagnostic tools and methods. For
proper diagnosis of the instrument cluster circuitry
that controls the washer fluid indicator, a diagnostic
scan tool is required. Refer to the appropriate diag-
nostic information.
WATER - IN - FUEL INDICATOR
DESCRIPTION
A water-in-fuel indicator is standard equipment in
all instrument clusters. The water-in-fuel indicator is
located near the lower edge of the instrument cluster,
to the left of the multi-function indicator display. The
water-in-fuel indicator consists of the International
Control and Display Symbol icon for ªWater In Fuelº
imprinted within a rectangular cutout in the opaque
layer of the instrument cluster overlay. The dark
outer layer of the overlay prevents the indicator from
being clearly visible when it is not illuminated. An
amber Light Emitting Diode (LED) behind the cutout
in the opaque layer of the overlay causes the icon to
appear silhouetted against an amber field through
the translucent outer layer of the overlay when the
indicator is illuminated from behind by the LED,
which is soldered onto the instrument cluster elec-
tronic circuit board. The water-in-fuel indicator is
serviced as a unit with the instrument cluster.
OPERATION
The water-in-fuel indicator gives an indication to
the vehicle operator when there is excessive water
