condition, 245°F (118°C), the cluster will illuminate
the warning indicator, request a single chime, and
move the gauge pointer to the appropriate position.
When the temperature reading falls below Temper-
ature High, the cluster will turn OFF the warning
indicator. While the temperature is between the
Temperature High and Temperature Critical levels,
the cluster will maintain the pointer at the Temper-
ature High position.
When the cluster receives a bus message indicat-
ing the coolant temperature has reached or ex-
ceeded the Temperature Critical condition, 260°F
(120°C), the cluster will flash the warning indicator,
request a continuous chime, and move the gauge
pointer to the appropriate position. When the tem-
perature reading falls below the Temperature Crit-
ical point, the cluster will stop flashing the warning
indicator. The indicator remains ON if above the
Temperature High point, or OFF if below. When
descending from a Temperature Critical to a Tem-
perature High condition, no chime will be re-
quested. While the temperature is at or above the
Temperature Critical level, the cluster will main-
tain the pointer at the Temperature Critical pointer
position.
ENGINE OIL PRESSURE WARNING INDICATOR
This indicator is located in the Oil Pressure
gauge. The non- serviceable LED is hardwired to
the MIC. The cluster will illuminate the indicator
when the appropriate PCI bus message is received
indicating the oil pressure has reached a Low
Pressure condition, 10 psi (69 kPa) and engine
speed is greater than 450 RPM. The cluster will
move the gauge pointer to the appropriate position,
illuminate the warning indicator, and request a
single chime. When the cluster receives bus data
indicating oil pressure greater than 10 psi (69 kPa)
at 450 RPM, it will turn OFF the indicator.
ENGINE OIL TEMPERATURE WARNING
INDICATOR
This indicator is located in the Oil Temperature
gauge. The non- serviceable LED is hardwired to
the MIC. When the cluster receives a PCI bus
message indicating the oil temperature has reached
or exceeded the Temperature High condition, 290°F
(144°C), the cluster will illuminate the oil temper-
ature warning indicator, request a single chime,
and move the gauge pointer to the appropriate
position. When the temperature reading falls below
Temperature High, the cluster will turn OFF the
warning indicator. While the temperature is be-
tween the Temperature High and Temperature
Critical levels, the cluster will maintain the pointer
at the Temperature High pointer position.
When the cluster receives a bus message indicat-
ing the oil temperature has reached or exceeded the
GENERAL INFORMATION
Temperature Critical condition, 300°F (160°C), the
cluster will flash the warning indicator, request a
continuous chime, and move the gauge pointer to
the appropriate position. When the temperature
reading falls below the Temperature Critical point,
the cluster will stop flashing the warning indicator.
The indicator remains ON if above the Temperature
High point, or OFF if below. When descending from
a Temperature Critical to a Temperature High
condition, no chime will be requested. While the
temperature is at or above the Temperature Critical
level, the cluster will maintain the pointer at the
Temperature Critical pointer position.
LOW FUEL WARNING INDICATOR
This indicator is located in the Fuel Gauge. The
LED indicator is non- serviceable. The LFW ON
point is at or below the 1/8 tank gauge position. The
LFW OFF point will be above the 1/8 tank position.
The LFW indicator will only be illuminated when
the Fuel Gauge pointer is in between 1/8 position
and 'E'. A chime request will be sent to the BCM via
a PCI Bus message and will coordinate with illumi-
nating of the LFW.
SKIP SHIFT INDICATOR
This indicator is located in the Tachometer. The
Skip Shift indicator is comprised of an Amber LED
and a Red LED that share a common chimney in the
cluster. The LED's are non- serviceable. The cluster
controls the Skip Shift indicator via 2 inputs: A PCI
Bus message from the PCM and the Tachometer
gauge pointer position. Upon receipt of the appro-
priate PCI message, the cluster will illuminate the
Amber LED when commanded ON, or will turn the
indicator OFF. When the Amber LED (Skip Shift) is
illuminated it is necessary to shift from first to
fourth gear.
When the tachometer pointer indicates 5600
RPM, the cluster will illuminate the Red LED
(Redline). The Red LED will turn OFF when the
tachometer pointer indicates 5500 RPM. The Red
LED will have priority over the Amber LED. If the
Red LED is turned OFF and the Amber LED is still
requested ON, the Amber LED will be illuminated.
The PCM locks out second and third gear and the
cluster will illuminate the Skip Shift Amber LED
when the following conditions are met:
•
Engine coolant
(106°F)
• Vehicle speed is between 12 - 20 MPH (19 - 32
kph)
•
Engine operating above 1322 RPM
• The PCM verified first gear speed/RPM
• Throttle position sensor (TPS) signal is less than
0.68 volt above closed throttle (23 percent throt-
tle opening)
15
temperature exceeds 41°C
