2002 CHRYSLER CARAVAN coolant temperature

ULES/POWERTRAIN CONTROL MODULE -
DESCRIPTION) section for more DTC information.
The Check Gauges Lamp (if equipped) or Battery
Lamp monitors:charging system voltage,engine
coolant temperature and engine oil pressure. If an
extreme condition is indicated, the lamp will be illu-
minated. The signal to activate the lamp is sent via
the PCI bus circuits. The lamp is located on the
instrument panel. Refer to the Instrument Cluster
section for additional information.
The PCM uses the inlet air temperature sensor to
control the charge system voltage. This temperature,
along with data from monitored line voltage, is used
by the PCM to vary the battery charging rate. The
system voltage is higher at cold temperatures and is
gradually reduced as the calculated battery tempera-
ture increases.
The ambient temperature sensor is used to control
the battery voltage based upon ambient temperature
(approximation of battery temperature). The PCM
maintains the optimal output of the generator by
monitoring battery voltage and controlling it to a
range of 13.5 - 14.7 volts based on battery tempera-
ture.
DIAGNOSIS AND TESTING - ON-BOARD
DIAGNOSTIC SYSTEM
The Powertrain Control Module (PCM) monitors
critical input and output circuits of the charging sys-
tem, making sure they are operational. A Diagnostic
Trouble Code (DTC) is assigned to each input and
output circuit monitored by the OBD system. Some
circuits are checked continuously and some are
checked only under certain conditions.
If the OBD system senses that a monitored circuit
is bad, it will put a DTC into electronic memory. The
DTC will stay in electronic memory as long as the
circuit continues to be bad. The PCM is programmed
to clear the memory after 50 engine starts if the
problem does not occur again.
DIAGNOSTIC TROUBLE CODES
A DTC description can be read using the DRBIIIt
scan tool. Refer to the appropriate Powertrain Diag-
nostic Procedures manual for information.
A DTC does not identify which component in a cir-
cuit is bad. Thus, a DTC should be treated as a
symptom, not as the cause for the problem. In some
cases, because of the design of the diagnostic test
procedure, a DTC can be the reason for another DTC
to be set. Therefore, it is important that the test pro-
cedures be followed in sequence, to understand what
caused a DTC to be set.ERASING DIAGNOSTIC TROUBLE CODES
The DRBIIItScan Tool must be used to erase a
DTC.
The following procedures may be used to diagnose
the charging system if:
²the check gauges lamp or battery lamp is illumi-
nated with the engine running
²the voltmeter (if equipped) does not register
properly
²an undercharged or overcharged battery condi-
tion occurs.
Remember that an undercharged battery is often
caused by:
²accessories being left on with the engine not
running
²a faulty or improperly adjusted switch that
allows a lamp to stay on. Refer to Ignition-Off Draw
Test (Refer to 8 - ELECTRICAL/BATTERY SYSTEM/
BATTERY - STANDARD PROCEDURE)
INSPECTION
The Powertrain Control Module (PCM) monitors
critical input and output circuits of the charging sys-
tem, making sure they are operational. A Diagnostic
Trouble Code (DTC) is assigned to each input and
output circuit monitored by the On-Board Diagnostic
(OBD) system. Some charging system circuits are
checked continuously, and some are checked only
under certain conditions.
Refer to Diagnostic Trouble Codes in; Powertrain
Control Module; Electronic Control Modules for more
DTC information. This will include a complete list of
DTC's including DTC's for the charging system.
To perform a complete test of the charging system,
refer to the appropriate Powertrain Diagnostic Proce-
dures service manual and the DRBIIItscan tool.
Perform the following inspections before attaching
the scan tool.
(1) Inspect the battery condition. Refer to the Bat-
tery section (Refer to 8 - ELECTRICAL/BATTERY
SYSTEM - DIAGNOSIS AND TESTING) for proce-
dures.
(2) Inspect condition of battery cable terminals,
battery posts, connections at engine block, starter
solenoid and relay. They should be clean and tight.
Repair as required.
(3) Inspect all fuses in both the fuseblock and
Power Distribution Center (PDC) for tightness in
receptacles. They should be properly installed and
tight. Repair or replace as required.
(4) Inspect generator mounting bolts for tightness.
Replace or tighten bolts if required. Refer to the Gen-
erator Removal/Installation section of this group for
torque specifications (Refer to 8 - ELECTRICAL/
CHARGING - SPECIFICATIONS).

GLOW PLUG
DESCRIPTION
Glow plugs are used to help start a cold or cool
engine (Fig. 1). The glow plugs will heat up and glow
to heat the combustion chamber of each cylinder. An
individual glow plug is used for each cylinder. Each
glow plug is threaded into the left side of the cylinder
head below the cylinder head cover/intake manifold.
OPERATION
Each glow plug will momentarily draw approxi-
mately 25 amps of electrical current during the ini-
tial key ªONº cycle. This is on a cold or cool engine.
After heating the current draw will drop to approxi-
mately 9±12 amps per plug.
Total momentary cuurent draw for all four glow
plugs is approximately 100 amps on a cold engine
dropping to a total of approximately 40 amps after
the plugs are heated.
Electrical operation of the glow plugs is controlled
by two glow plug relays. Each glow plug relay con-
trols two glow plugs. Refer to glow plug relays for
more information.
GLOW PLUG RELAY
DESCRIPTION
There are two glow plug relays. These relays are
located in the Power Distribution Center (PDC) in
the engine compartment (Fig. 2).
OPERATION
When the ignition (key) switch is place in the ON
position, a signal is sent to the ECM relating current
engine coolant temperature. This signal is sent from
the engine coolant temperature sensor.
After receiving this signal, the ECM will determine
if, when and for how long of a period the glow plug
relays should be activated. This is done before, dur-
ing and after the engine is started. Whenever the
glow plug relays are activated, it will control the 12
volt 100 amp circuit for the operation of the four
glow plugs. Each relay control two glow plugs.

The Glow Plug lamp is tied to this circuit. Lamp
operation is also controlled by the ECM.
With a cold engine, the glow plug relays and glow
plugs may be activated for a maximum time of 200
seconds. Refer to the following Glow Plug Control
chart for a temperature/time comparison of the glow
plug relay operation.
In this chart, Pre-Heat and Post-Heat times are
mentioned. Pre-Heat is the amount of time the glow
plug relay control circuit is activated when the igni-
tion (key) is switched ON, without the engine run-
ning. Post-Heat is the amount of time the glow plug
relay control circuit is activated after the engine is
operated. The Glow Plug lamp will not be activated
during the post-heat cycle.

CAMSHAFT POSITION
SENSOR
DESCRIPTION
The camshaft position (CMP) sensor is mounted in
the top of cylinder head cover/intake manifold at the
rear of the engine. The CMP sensor is a hall effect
device (Fig. 3).
OPERATION
The CMP sensor is a hall effect switch. A tooth
made of a ferromagnetic material is attached to the
camshaft. When this tooth passes the CMP sensor an
lectronic signal is created. This signal is then sent to
the engine control module (ECM). This signal is used
by the ECM to determine which cylinder has just
entered its compression phase.

WATER IN FUEL LAMP - EXPORT
The Water In Fuel Lamp is located in the instru-
ment cluster. When moisture is found within the fuel
system, the sensor sends a message via the PCI data
bus to the instrument cluster. The sensor is located
underneath the vehicle, directly above the rear axle.
The sensor is housed within the fuel filter/water sep-
arator assembly cover. The sensor is not serviced sep-
arately. If found defective, the entire assembly cover
must be replaced.
OPERATION
Refer to the vehicle Owner's Manual for operation
instructions and conditions for the Instrument Clus-
ter Gauges.
WATER IN FUEL LAMP - EXPORT
The Water In Fuel Sensor is a resistive type
switch. It is calibrated to sense the different resis-
tance between diesel fuel and water. When water
enters the fuel system, it is caught in the bottom of
the fuel filter/water separator assembly, where the
sensor is located. Water has less resistance than die-
sel fuel. The sensor then sends a PCI data bus mes-
sage to the instrument cluster to illuminate the
lamp.
If the lamp is inoperative, perform the self diag-
nostic test on the instrument cluster to check the
lamp operation before continuing diagnosis.
