IDLE SPEED INSPECTION
1. INITIAL CONDITIONS
(a) Engine at normal operating temperature
(b) Air cleaner installed
(c) All pipes and hoses of air induction system connected
(d) All vacuum lines properly connected
(e) MFI/SFI system wiring connectors fully plugged
(f) All operating accessories switched OFF
(g) Ignition timing set correctly
(h) Transmission in neutral position
2. CONNECT TACHOMETER
Connect the test probe of a tachometer to terminal IG
(±) of the data link connector 1.
NOTICE:
wNever allow the tachometer terminal to touch
ground as it could result in damage to the Igniter
and/or ignition coil.
wAs some tachometers are not compatible with this
ignition system, we recommend that you confirm
the compatibility of yours before use.
(b) Check the idle speed.
Idle speed (w/ Cooling fan OFF):
750+50 rpm
If the idle speed is not as specified, check the IAC
system.
4. DISCONNECT TACHOMETER 3. INSPECT IDLE SPEED
(a) Race the engine at 2,500 rpm for approx. 90 seconds.

CIRCUIT DESCRIPTION
The ECM determines the ignition timing, turns on Tr, at a predetermined angle ('*CA) before the
desired ignition timing and outputs an ignition signal (IGT) ª1º to the igniter.
Since the width of the IGT signal is constant, the dwell angle control circuit in the igniter determines
the time the control circuit starts primary current flow to the ignition coil based on the engine rpm and
ignition timing one revolution ago, that is, the time the Tr
2 turns on.
When it reaches the ignition timing, the ECM turns Tr, off and outputs the IGT signal ªOº.
This turns Tr2 off, interrupting the primary current flow and generating a high voltage in the secondary
coil which causes the spark plug to spark. Also, by the counter electromotive force generated when
the primary current is interrupted, the igniter sends an ignition confirmation signal (IGF) to the ECM.
The ECM stops fuel injection as a fail safe function when the lG F signal is not input to the ECM.
wOpen or short in IG F or IGT circuit from
igniter to ECM.

3. Wiring Diagram
4. Construction
The engine immobiliser system consists of the transponder key (ignition key), transponder key coil, trans-
ponder key amplifier, and ECM.
Transponder Key (Ignition Key)
A transponder chip is embedded in the grip of the
ignition key. Each transponder chip contains an
individual transponder key-code (ID code). The
key does not need an internal battery to transmit
a key code.
Transponder Key Coil and Transponder Key Amplifier
The transponder key coil is a ring-shaped coil installed around the ignition key cylinder. The transponder
key amplifier is installed in the back of the key cylinder.
An electrical power circuit to provide power to the transponder key coil has been enclosed in the amplifier.
ECM
The control circuit of the engine immobiliser system has been integrated inside the ECM. As a result, the
time has been reduced taken for the engine to start in case of mismatching key code thus improving the
system's theft deterrent performance.
A maximum of 10 different transponder key codes (master key: 7 types, sub key: 3 types) can be registered
in the ECM.

E GLOSSARY OF TERMS AND SYMBOLS
BATTERY
Stores chemical energy and
converts it into electrical energy.
Provides DC current for the auto's
various electrical circuits.GROUND
The point at which wiring attaches to
the Body, thereby providing a return
path for an electrical circuit; without a
ground, current cannot flow.
CAPACITOR (Condenser)
A small holding unit for temporary
storage of electrical voltage.HEADLIGHTS
Current flow causes a headlight
filament to heat up and emit light. A
headlight may have either a single
(1) filament or a double (2) filament
1. SINGLE
FILAMENT
CIGARETTE LIGHTER
An electric resistance heating
element.2. DOUBLE
FILAMENT
CIRCUIT BREAKER
Basically a reusable fuse, a circuit
breaker will heat and open if too
much current flows through it.
Some units automatically reset when
cool, others must be manually reset.HORN
An electric device which sounds a
loud audible signal.
DIODE
A semiconductor which allows
current flow in only one direction.IGNITION COIL
Converts low±voltage DC current
into high±voltage ignition current for
firing the spark plugs.
DIODE, ZENERA diode which allows current flow in one
direction but blocks reverse flow only up
to a specific voltage. Above that potential,
it passes the excess voltage. This acts as
a simple voltage regulator.LIGHT

Channels high±voltage current from
the ignition coil to the individual
spark plugs.METER, ANALOG
Current flow activates a magnetic
