3. IGNITION SYSTEM OPERATION
This ignition system does not use a conventional distributor and coil. It uses a crankshaft position
sensor input to the Engine Control Module (ECM).
The ECM then determines Electronic Spark Timing (EST) and triggers the electronic ignition
system ignition coil.
This type of distributorless ignition system uses a "waste spark" method of spark distribution.
Each cylinder is paired with the cylinder that is opposite it (2.3L DOHC: 2 - 3 or 1 - 4, 3.2L
DOHC: 1 - 6 or 2 - 5 or 3 - 4).
The spark occurs simultaneously in the cylinder coming up on the compression stroke and in the
cylinder coming up on the exhaust stroke.
The cylinder on the exhaust stroke requires very little of the available energy to fire the spark plug.
The remaining energy is available to the spark plug in the cylinder on the compression stroke.
These systems use the EST signal from the ECM to control the EST.
The ECM uses the following information: Engine load (mass air flow sensor, manifold air pressure
sensor).
Engine coolant temperature.
Intake air temperature.
Crankshaft position.
Engine speed (rpm).
1) Electronic Ignition System Ignition Coil
The Electronic Ignition (EI) system ignition coil is located on the cylinder head cover.
The double ended coils re ceive the signal for the ECM which controls the spark advance.
Each EI system ignition coil provides the high voltage to two spark plugs simultaneously;
3.2L DOHC
T1/1: cylinder 2 and 5
T1/2: cylinder 3 and 4
T1/3: cylinder 1 and 6
The EI system ignition coil is not serviceable and must be replaced as an assembly.

1. CAUTIONS WHEN WORKING ON ELECTRICAL UNITS
80℃
10A 15A
Disconnect the negative cable from the
battery in advance when working on
electrical units. -
Make sure to turn "OFF" the ignition switch
and other lamp switches before
disconnecting or connecting the negative
battery cable. (Otherwise, semiconductor
parts can be damaged.)
Do not drop or appy excessive impact to
sensors and relays. -
If a fuse is blown, replace it with a fuse
which has the correct amperage rating. If
you use a fuse with higher capacity than
the specification, the component can be
damaged or catch fire. -

(2) Rain Sensor Coupled Wiper
▶ System layout
This vehicle has a different wiper control logic compared to other models. As shown in the
system diagram, the rain sensor unit does not control wiper directly. The rain sensor unit sends
infrared rays signal through LED and then receives it with photo diode and then sends the
returned signal to STICS and the STICS controls the wipers directly.
For more details, refer to rain sensing wiper section in this manual.

The wiper relay (LO) is turned on and the wiper motor runs one cycle when the wiper sensitivity is
changed to 2 from 3 during receiving the malfunction signal (1) from the rain sensor. However,
the wiper motor can be operated only when the rain sensor detects the "Rain Detected" signal. 1)
If the volume sensitivity is changed more than 2 stages within 2 seconds, the wiper motor
runs only one cycle. ▶ Defective rain sensor

2. Vehicle speed calculation
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
1 [pulses/sec] = 60 [km/h] x 60 [sec] / 637 pulses = 1.41 [km/h]
3. VOLUME calculation
Calculates the INT VOLUME with 5 grades as shown in the table in next page. -
4. Pause time calculation
Pause time: the duration that wipers are stopped at parking position
Elapsed time: the duration after the wiper motor started to operate from parking position
The pause time is calculated by the vehicle speed and VOLUME value as shown in the table
in next page. -
-
-
If the pause time is below 1.0 second, the wipers operate without pause.
If the pause time is over 1.5 seconds, the wipers operate intermittently. ·
