4. As some tachometers are not compatible with this igni-
tion system, we recommend that you confirm the
compatibility of your unit before use.
5. NEVER allow the tachometer test probe to touch ground
as this could damage the igniter and/or ignition coil.
6. Do not disconnect the battery when the engine is run-
ning.
7. Check that the igniter is properly grounded to the body.
PRECAUTIONS
1. Do not leave the ignition switch on for more than 10
minutes if the engine will not start.
2. (3S±FE)
When a tachometer is connected to the system, con-
nect the test probe of the tachometer to service con-
nector of the distributor.
3. (2VZ±FE)
When a tachometer is connected to the system, con-
nect the test probe of the tachometer to terminal IG E)
of the check connector.

ELECTRONIC SPARK ADVANCE (ESA)
The ECU is programmed with data for optimum ignition timing
under any and all operating conditions. Using data provided
by sensors which monitor various engine functions (rpm, in-
take air volume, eng. temperature, etc.) the microcomputer
(ECU) triggers the spark at precisely the right instant.

ON±VEHICLE INSPECTION (3S±FE)
SPARK TEST
CHECK THAT SPARK OCCURS
(a) Disconnect the high±tension cords from the spark plugs.
(b) Remove the spark plugs.
(c) Install the spark plugs to each high±tension cord.
(d) Ground the spark plug.
(e) Check if spark occurs while engine is being cranked.
HINT: To prevent gasoline from being injected from injectors
during this test, crank the engine for no more than 1
± 2 seconds at a time.
If the spark does not occurs, perform the test as follows:
CHECK RESISTANCE OF IGNITION COIL
(See page IG±7)
Resistance (Cold):
Primary 0.38 ± 0.46
Secondary 7.7 ± 10.4 k
CHECK POWER SUPPLY TO IGNITION
COIL AND IGNITER
1. Ignition switch turn to ON.
2. Check that there is battery voltage at
ignition coil positive (+) terminal. CHECK RESISTANCE OF HIGH±TENSION
CORD (See page IG±6)
Maximum resistance: 25 k per cord
CHECK RESISTANCE OF SIGNAL
GENERATOR (PICKUP COIL) (See page
IG±8) Resistance: 140 ± 180
CHECK AIR GAP OF DISTRIBUTOR
(See page IG±7)
Air gap: 0.2 mm (0.008 in.) or moreCHECK CONNECTION OF IGNITION
COIL, IGNITER AND DISTRIBUTOR
CONNECTORS
Check wiring between ignition switch
to ignition coil and igniter.

2. INSPECT HIGH±TENSION CORD RESISTANCE
Using an ohmmeter, measure the resistance without discon-
necting the distributor cap.
Maximum resistance: 25 k
per cord
If the resistance is greater than maximum, check the termi-
nals. If necessary, replace the high±tension cord and/
or distributor cap.
3. VISUALLY INSPECT SPARK PLUGS
Check the spark plug for electrode wear, thread damage or
insulation damage.
If abnormal, replace the spark plug.
Recommended spark plug: ND Q1 6R±U11
NGK6CPR5EY11
INSPECTION OF HIGH±TENSION
CORDS
1. CAREFULLY REMOVE HIGH±TENSION CORDS BY
THEIR RUBBER BOOTS FROM SPARK PLUGS
NOTICE: Pulling on or bending the cords may damage the
conductor inside.
INSPECTION OF SPARK PLUGS
1. REMOVE SPARK PLUGS
Using a 16 mm plug wrench, remove the spark plug.
2. CLEAN SPARK PLUG
Using a spark plug cleaner or wire brush, clean the spark
plug.

INSPECTION OF DISTRIBUTOR
1. INSPECT AIR GAP
Using a feeler gauge, measure the gap between the signal
rotor and pickup coil projection.
Air gap: 0.2 mm (0.008 in.) or more
If the air gap is not as specified, replace the distributor
housing assembly.INSPECTION OF IGNITION COIL
1. INSPECT PRIMARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between posi-
tive (+) and negative (±) terminals.
Primary coil resistance (Cold): 0.38 ± 0.46
If the resistance is not as specified, replace the ignition coil.
2. INSPECT SECONDARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between the
positive (+) and high±tension terminals.
Secondary coil resistance (Cold): 7.7 ±10.4 k
If the resistance is not as specified, replace the ignition coil.4. ADJUST ELECTRODE GAP
Carefully bend the outer electrode to obtain the correct elec-
trode gap.
Correct electrode plug: 1.1 mm (0.043 in.)
5. INSTALL SPARK PLUGS
Using a 16 mm plug wrench, install the spark plug.
