Turn Signal On: When the BCM detects a turn
signal input continuously for
1.0mile/0.6km and the vehicle
speed is greater than 15 mph/
24kph, the chime will sound until
the specific turn signal is can-
celled.
Dome Lights On: Ignition is in the lock position,
driver door ajar, and the dome
light switch is left in the on
position. The chime will sound
until one of the above conditions
is removed or until the battery
protection time of 15 minutes has
expired.
Low Oil Pres-
sure:The chime will sound when the
engine is operating and the oil
pressure drops below 4psi/27.5kPa.
Engine

GENERAL INFORMATION

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.

GENERAL INFORMATION

When Monitored and Set Condition:
ORC, CALIBRATION MISMATCH - STORED
When Monitored: With ignition on, the ORC monitors the PCI Bus for the VIN message
containing the body style. The PCM transmits the 17- character VIN message every 14
seconds. Note: The VIN message should match the vehicle VIN plate.
Set Condition: If the Body style stored in ORC does not exactly match the vehicle body
style indicated by the PCM, then the fault shall be set.
ORC, CLUSTER MESSAGE MISMATCH - STORED
When Monitored: After the MIC bulb test is completed, the ORC compares the Lamp
Request by ORC (On or Off) and the Lamp on by MIC (On or Off) PCI Bus messages. Each
message is transmitted one time per second or when a change in the lamp state occur.
Set Condition: If the Lamp Request by ORC (On or Off) and the Lamp on by MIC (On or
Off) messages do not match, the code will set.
ORC, DRIVER SBS OPEN - STORED
When Monitored: The ORC monitors the Seat Belt Switch circuit for an open condition.
Set Condition: The code will set if the ORC does not detect the correct circuit voltage.
ORC, DRIVER SBS SHORT TO BATTERY - STORED
When Monitored: The ORC monitors the Seat Belt Switch circuit for an short to battery.
Set Condition: The code will set if the ORC detects high circuit voltage.
ORC, DRIVER SBS SHORT TO GROUND - STORED
When Monitored: The ORC monitors the Seat Belt Switch circuit for a shorted together
or shorted to ground condition.
Set Condition: The code will set if the ORC detects low circuit voltage.
ORC, DRIVER SBT CIRCUIT OPEN - STORED
When Monitored: When the ignition is On, the ORC monitors the resistance of the Driver
Seat Belt Tensioner circuits.
Set Condition: The ORC has detected an open circuit or high resistance on the Driver
Seat Belt Tensioner circuits.
ORC, DRIVER SBT CIRCUIT SHORT - STORED
When Monitored: When the ignition is on, the ORC monitors the resistance of the Driver
Seat Belt Tensioner circuits.
Set Condition: The ORC has detected low resistance in the Driver Seat Belt Tensioner
circuits.
