IGNITION CONTROL

2009 ENGINE

Ignition Control - Service Information - Grand Caravan, Town & Country

DESCRIPTION

The 3.3/3.8L engines use a distributorless ignition system and is commonly referred to as Direct Ignition
System (DIS). The 4.0L engine uses a Coil on Plug design. The system's main components are the ignition
coils, crankshaft position sensor, camshaft position sensor and spark plugs.

OPERATION

The crankshaft position sensor and camshaft position sensor are hall effect devices. The camshaft position
sensor and crankshaft position sensor generate square wave pulses that are inputs to the PCM. The PCM
determines engine position from these sensors. The PCM calculates injector sequence and ignition timing from
crankshaft AND camshaft position.

SPECIFICATIONS

FIRING ORDER

3.3/3.8L

NOTE:

All engines use a fixed ignition timing system. Basic ignition timing is not
adjustable. All spark advance is determined by the Powertrain Control Module
(PCM).

CABLE, IGNITION

REMOVAL

Disconnect and isolate negative battery cable at battery.

Remove spark plug cable from coil first.

Always remove the spark plug cable by grasping the top of the spark plug insulator, turning the boot 1/2 turn
and pulling straight up in a steady motion.

INSTALLATION

Failure to route the cables properly could cause the radio to reproduce ignition noise, cross ignition of the spark
plugs or short circuit the cables to ground. Install spark plug insulators over spark plugs. Ensure the top of the
spark plug insulator covers the upper end of the spark plug tube, then connect the other end to coil pack.

Install negative battery cable to battery.

WARNING:

Always turn the engine off and disconnect the battery prior to servicing
the spark plug cables. Do not attempt to remove a spark plug cable while
the motor is running. Failure to follow these directions may result in
serious or fatal injury.

Fig. 9: Identifying Glow Plug
Courtesy of CHRYSLER LLC

Glow plugs are used to help start a cold or cool engine. 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.

OPERATION

CAUTION: The glow plugs operate on a 4.4-volt system. The glow plugs DO NOT

tolerate any over voltage. Full battery voltage will destroy the glow plug
immediately. DO NOT test the glow plugs with a 12V source as damage will
occur to the glow plug.

CAUTION:



Never bend, bump or knock the fast metallic glow plugs.



Fast metallic glow plugs must not be handled loose in a container.
Store, handle, and transport them only in original boxes.



If there is any doubt about the proper condition of a glow plug, do not
reuse it.



Do not clean the glow plugs with abrasive or aggressive media.



Avoid dipping the glow plug into fluids.



Read Diagnostic Trouble Codes (DTCs). If a glow plug problem is
indicated, do not start the engine.

CAUTION: Disregarding these instructions may cause severe engine damage.

The Engine Control Module (ECM) monitors various engine sensors. When the ignition key is turned to the ON
position, the ECM sends a signal to the glow plug module (relay) to turn on, and cycle, the glow plugs for a pre-
determined amount of time, plus illuminate the glow plug light in the instrument panel. Once activated, the
element inside of the core of the glow plug begins to glow. Each glow plug draws approximately 8 amps, for a
total system amperage of 32 amps at 22° C (72° F) ambient temperature. If there is a fault with the glow plug
system, the ECM will store a fault code.

DIAGNOSIS AND TESTING

GLOW PLUGS

1. Measure the electrical resistance of each glow plug while it is still installed in the cylinder head.

Resistance should be less than 0.8ohms between the electrical connector point on the glow plug and the
cylinder head. The ground contact on the DVOM must be as close as possible to the point where the glow
plug contacts the cylinder head to avoid erratic resistance measurements.

2. If the resistance is out of tolerance, remove the glow plug from the cylinder head and check the resistance

again.

3. Use the actuator test function of the scan tool to test the glow plug module and glow plug lamp. The glow

plug module's on-board diagnostic tests will automatically check the electrical condition of the entire

CAUTION: The glow plugs operate on a 4.4-volt system. DO NOT test the glow plugs

with a 12 V source as damage will occur to the glow plug(s).

CAUTION: DO NOT attempt to start the engine until the glow plug system tests

correctly.

glow plug system.

4. After the scan tool glow plug actuator test function is complete, if MIL is OFF and no glow plug DTCs

are present, testing is complete and the engine can be started.

5. If MIL is still ON, check the harness connectors of glow plugs, repair any loose or damaged connections,

and run the glow plug actuator test again.

6. If MIL is still ON and glow plug DTCs are present, refer to the appropriate Diagnostic Information and

follow the diagnostic test(s) related to the active or stored DTCs.

This vehicle is equipped with a Wireless Ignition Node (WIN). The WIN, along with the FOB with Integrated
Key (FOBIK) are the primary components of the keyless ignition system. The only visible component of the
WIN is the ignition switch located on the face of the instrument panel just to the inboard side of the steering
column. The remainder of the WIN including its mounting provisions and electrical connections are concealed
within the instrument panel.

In addition to replacing a conventional keyed ignition switch, the WIN is an integrated electronic receiver that
serves as the base station in the vehicle. It communicates with other electronic modules in the vehicle over the
Controller Area Network (CAN) data bus.

The WIN interfaces with the Remote Keyless Entry (RKE) FOBIK and the Tire Pressure Monitor (TPM)
sensors (if equipped) using Radio Frequency (RF) communication, with the Sentry Key Immobilizer System
(SKIS) transponder within the FOBIK using Low Frequency (LF) RF communication.

The WIN cannot be adjusted or repaired, but is flash update capable. If ineffective or damaged the entire WIN
must be replaced. Refer to Electrical - Electronic Control Modules/Electronic Control
Modules/RECEIVER, Wireless Ignition Node - Removal .
