ating and the combustion air fan operation is sus-
pended for 3 seconds. Subsequently, the combustion
air fan speed is increased in two ramps within 56
seconds to nearly full load operation. After a stabi-
lization phase of 15 seconds, the combustion air fan
speed is again increased in a ramp within 50
seconds to nearly full load. After reaching full load
fuel delivery, the glow plug is deactivated and the
combustion air fan operation is increased to full
load. During the subsequent 45 seconds, as well as
in normal operation, the glow plug functions as a
flame sensor to monitor the flame condition. After
all these events, the automatically controlled heat-
ing operation starts.
In case of a no flame or a flame out condition, a
restart is automatically initiated. If the no flame
condition persists, fuel delivery is stopped and the
heater enters an error lockout mode with a run-
down of the combustion air fan. This will set one or
more DTCs in the DCHA Control's memory. If six
continuous attempts to start the heater fail due to
one or more faults in the DCHA system, the heater
enters a heater lockout mode. This will set DTC
B1813 along with any other fault(s) that the DCHA
Control identified.
3.10.3.2 HEATING
During the automatically controlled heating op-
eration, when the coolant temperature reaches
72ÉC (162ÉF), the heater will switch to a part load
operation. When the coolant temperature reaches
75ÉC (167ÉF) or if the heater runs for longer than 76
minutes the heater will switch to a control idle
period. If the coolant temperature drops to 71ÉC
(160ÉF) during a control idle period, the heater will
perform a regular starting sequence into full load
operation. A drop in coolant temperature to 65ÉC
(149ÉF) during part load operation will cause the
heater to switch to a full load operation.
3.10.3.3 DEACTIVATION
The DCHA will deactivate if the:
²engine is turned off.
²coolant temperature reaches 75ÉC (167ÉF).
²heater runs longer than 76 minutes.
²fuel tank has less than 1/8 of a tank of fuel.
²Power switch on the A/C ± Heater Control Module
is off.
²Blend Control on the A/C ± Heater Control Mod-
ule is set below 75% reheat.
When the heater is deactivated, the combustion
stops and a run-down sequence begins. During the
run-down sequence, the combustion air fan contin-
ues operation to cool down the heater. The fan is
automatically switched off after the run-down se-
quence is complete. The run-down time and thecombustion air fan speed depend on the heater
operating condition at the time of deactivation.
Run-down time is approximately 175 seconds when
deactivated in full load operation and approxi-
mately 100 seconds when deactivated in part load
operation.
3.10.4 DIAGNOSTICS
The DCHA is fully addressable with the DRBIIIt.
System tests include a Field Mode Test to activate
the DCHA for diagnostic testing purposes. The
DCHA Control will store up to three DTCs in its
memory. If the Controller detects a new fault in the
DCHA system, one that is not already stored in its
memory, it will clear the oldest of the three stored
DTCs, and it will store the new fault's DTC. If the
Controller detects a reoccurrence of a stored fault, it
will overwrite that fault's DTC with the most recent
occurrence.
3.11 INSTRUMENT CLUSTER
The Instrument Cluster receives and sends mes-
sages to other modules via the PCI bus circuit. The
indicator lamps will illuminate briefly for a bulb
check when the ignition is turned from off to run.
All of the gauges receive their information via the
PCI bus from the powertrain control module and
body control module.
The gauges and the LEDs are not individually
replaceable thereby requiring complete replace-
ment of the Instrument Cluster if a repair is neces-
sary. In the event that the Instrument Cluster loses
communication with other modules on the PCI bus,
the cluster will display ªno busº in the VF display.
The Trip/Reset button is used to switch the dis-
play from trip to total mileage. Holding the button
when the display is in the trip mode will reset the
trip mileage. This button is also used to put the
cluster in self-diagnostic mode. The odometer dis-
play uses blue-green vacuum fluorescent digital
characters.
On base vehicles, the Instrument Cluster has
three gauges: Speedometer, Fuel and Engine Cool-
ant Temperature. A red dot moves transversely
through openings in the Instrument Cluster face
(P-R-N-D-2-1) to indicate the gear selected.
With all other models, the Instrument Cluster
also includes a Tachometer and uses a vacuum-
fluorescent shift indicator.
The odometer display and door/liftgate ajar indi-
cators turn on when a door is opened to assist both
the customer and service technician to view the
odometer without turning the ignition on.
21
GENERAL INFORMATION

On vehicles equipped with AutoStick, the display
includes an O/D OFF indicator that is illuminated
when the driver presses the Overdrive Off button
on the transaxle shifter.
3.11.1 INSTRUMENT CLUSTER SELF TEST
1. Depress and hold the Odometer Reset button.
2. Turn the ignition switch to the RUN/START
position.
3. Release the Odometer reset button.
The Instrument Cluster will illuminate all indi-
cators and step the gauges through several calibra-
tion points. Also, the odometer will display any
stored codes that may have set.
3.11.2 MESSAGE CENTER
The Message Center is located above the brow of
the Instrument Cluster. It houses the following
warning indicators: Check Engine/Service Engine
Soon, high beam, left and right turn signals, Secu-
rity Alarm Set, and low oil pressure. On base
models equipped with the three-speed transaxle,
these indicators appear in the face of the cluster.
The Security Alarm set indicator is a red circle.
Activation of Instrument Cluster indicators is
coordinated with indicators in the message center
and EVIC to avoid redundancy. A revised safety
standard now requires that the seat belt warning
lamp in the Instrument Cluster remain lit if the
driver seat belt is not buckled. A headlamp out ISO
indicator has been added to the Instrument Cluster
to alert the driver when a headlamp is not function-
ing.
3.12 INTERIOR LIGHTING
3.12.1 COURTESY LAMP CONTROL
The body controller has direct control over all of
the vehicle's courtesy lamps. The body computer
will illuminate the courtesy lamps under any of the
following conditions:
1. Any door ajar and courtesy lamp switch on the
headlamp switch is not in the dome off position.
2. The courtesy lamp switch on the headlamp
switch is in the dome on position.
3. A Remote Keyless Entry unlock message is re-
ceived.
4. Driver door unlocked with key (with VTSS only).
3.12.2 ILLUMINATED ENTRY
Illuminated entry will be initiated when the cus-
tomer enters the vehicle by unlocking the doors
with the key fob, or with the key if the vehicle is
equipped with vehicle theft alarm. Upon exiting thevehicle, if the lock button is pressed with a door
open, illuminated entry will cancel when the door
closes. If the doors are closed and the ignition
switch is turned on, the illuminated entry also
cancels. The illuminated entry feature will not
operate if the courtesy lamp switch is in the dome
off position.
3.12.3 INTERIOR LIGHTING BATTERY
SAVER
If any of the interior lamps are left on after the
ignition is turned off, the BCM will turn them off
after 8 minutes. To return to normal operation, the
courtesy lamps will operate after the dome lamp
switch or door ajar switch changes state. The glove
box and switched reading lamps require that the
ignition be turned to the on/acc position.
3.13 MEMORY SYSTEM
The memory system consists of power driver 's
seat, power mirrors and radio presets. The Memory
Seat/Mirror Module (MSMM) is located under the
driver 's seat. It receives input from the following:
driver 's manual 8-way seat switch, driver 's seat
position sensors, PCI bus circuits, and the power
mirror sensors. The module uses these inputs to
perform the following functions: position the driv-
er 's memory seat, both exterior mirrors (during
recalls), and send/receive the memory system infor-
mation over the PCI bus.
The Memory Set Switch is wired to the Body
Control Module (BCM). When a button (either #1 or
#2) is pressed on the set switch causes the to BCM
send a message to the MSMM which in turn sends
a motion status messages to the BCM. If the BCM
receives no motion from the MSMM it will send a
recall message to the MSMM and radio (once igni-
tion is in run or accessory). The MSMM will in turn
position the drivers seat, both mirrors along with
recalling the radio presets. If the drivers seat or
either exterior mirror is inoperative from its own
respective switches, use the service information
and schematic to diagnose the problem. This man-
ual addresses the memory problems only and it is
assumed there is not a basic component failure.
3.13.1 POWER SEAT
The memory power seat provides the driver with
2 position settings for the driver 's seat. Each power
seat motor is connected to the MSMM with two
motor drive circuits. Each circuit is switched be-
tween battery and ground. By being able to bi-
directionally drive the circuits, the MSMM controls
the movement of the motors based on input from
the power seat switch or from the position sensors
when performing a memory recall. Each motor
22
GENERAL INFORMATION

contains a potentiometer to monitor the seat posi-
tion. To monitor the position of the motor, the
MSMM sends out a 5-volt reference on the sensor
supply circuit. The sensor is grounded back to the
module on a common ground circuit. Based on the
position of the sensor, the MSMM monitors the
voltage change through the sensor on a separate
signal circuit.
The MSMM stores the input value of each of the
four seat potentiometers in memory when the sys-
tem requests a set. The driver can initiate a mem-
ory recall, using either the door mounted memory
switch or the RKE transmitter (if the remote linked
to memory feature is enabled via the EVIC). When
initiated, the MSMM adjusts the four seat sensors
(by using the motors) to match the memorized seat
position data.
For safety, the memory seat recall is disabled by
the MSMM when the vehicle is out of park position
or if the speed is not zero. Any obstruction to seat
movement over a 2-second delay will cause the seat
to stop moving in which case a stalled motor would
be detected by the MSMM and the corresponding
seat output would be deactivated. However, if the
object obstructing the seat is removed, the seat will
function normally again.
3.13.2 MEMORY MIRRORS
Each outside mirror contains vertical and hori-
zontal bi-directional drive positioning motors and
position sensors. The MSMM provides a 5-volt
reference on the signal circuit to each position
sensor. The sensors share a common ground circuit.
The MSMM monitors the position of the mirror
motors by measuring the voltage on each signal
circuit. When a memory position is set, the MSMM
monitors and stores the position of the outside
mirrors. The MSMM adjusts the mirrors to the
appropriate positions when a memory recall mes-
sage is received from the RKE or is requested from
the memory set switch.
The power mirror switch during non-memory
operation operates both mirrors independently of
the MSMM.
3.14 OVERHEAD CONSOLE
3.14.1 COMPASS/MINI-TRIP COMPUTER
(CMTC)
The compass/mini-trip computer is located in the
overhead console. It displays to the driver the
direction the vehicle is traveling and the current
outside temperature, as well as the following trav-
eler navigational information: average fuel econ-
omy (AVG ECO), distance to empty (DTE), instan-
taneous fuel economy (ECO), elapsed time (ET),and trip odometer (ODO). The information needed
for the CMTC functions is received over the PCI bus
from other modules.
3.14.2 ELECTRONIC VEHICLE
INFORMATION CENTER (EVIC)
The Electronic Vehicle Information Center
(EVIC) includes all the same functions and is lo-
cated in the same area as the Compass/Mini-Trip
Computer, but it adds a number of warning mes-
sages. Also, the EVIC messages are spelled out on
the screen, for example, DISTANCE TO EMPTY,
where the Mini-Trip Computer displays only shows
DTE.
If the compass/mini-trip computer or EVIC has
been replaced, it may be necessary to reset the
calibration.
3.14.3 SETTING THE COMPASS
The compass/mini-trip computer and EVIC are
self-calibrated and requires no adjustment. The
word CAL will be displayed to indicate that the
compass is in the fast calibrating mode. CAL will
turn off after the vehicle has gone in three complete
circles without stopping, in an area free of magnetic
disturbance.
If the module displays the temperature while the
compass is blank or shows a false reading, the
vehicle must be demagnetized. See the service man-
ual for the proper procedure.
If the compass still goes blank after the vehicle is
demagnetized, the compass/mini-trip/EVIC module
must be replaced.
3.14.4 SETTING THE VARIANCE
Variance is the difference between magnetic
north and geographic north. To determine the vari-
ance for the area you are in, refer to the following
zone map provided. The number shown for your
area is the variance number for your area.
1. Set the compass/mini-trip computer (CMTC) to
compass/temperature mode.
2. Press and hold down the RESET button for 5
seconds.NOTE:If the button is held for 10
