PRECAUTION
1. With a tachometer connected to the system, connect the
tester probe of the tachometer to terminal IG of the
DLC1.
2. With a timing light connected to the system, connect the
tester probe to the green wire of the igniter
3. As some tachometers are not compatible with this
ignition system, we recommend that you confirm the
compatibility of your unit before use.
4. Never allow the tachometer terminals to touch ground as
it could result in damage to the igniter and/or ignition
coil.
5. Do not disconnect the battery while the engine is
running.
6. Check that the igniter is properly grounded to the body.

ON±VEHICLE INSPECTION
SPARK TEST
CHECK THAT SPARK OCCURS
(a) Remove the ignition coil. (See ignition coil removal)
(b) Remove the spark plug.
(c) Install the spark plug to the ignition coil, and connect the
ignition coil connecter.
(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 se-
conds at time.
If the spark does not occur, do the test as follows:
SPARK TEST
CHECK CONNECTION OF IGNITION COIL, IGNITER
CHECK POWER SUPPLY TO IGNITION COIL AND
IGNITER
1. Turn ignition switch to ON.
2. Check that there is battery voltage at
ignition coil positive (+) terminal.
CHECK RESISTANCE OF IGNITION COIL(See page IG±23)Resistance: Cold Hot

CHECK RESISTANCE OF CAMSHAFT AND
CRANKSHAFT POSITION SENSOR

CHECK IGT SIGNAL FROM ECM(See page EG±519)
TRY ANOTHER IGNITER
Connect securely.
Check wiring between ignition switch
to ignition coil and igniter.
Replace the ignition coil.
Replace the camshaft and crankshaft position
sensor.
Check wiring between ECM,and igniter, and
then try another ECM.

SPARK PLUGS INSPECTION
NOTICE:
wNever use a wire brush for cleaning.
wNever attempt to adjust the electrode gap on used a spark
plug.
wSpark plugs should be replaced every 100,000 km (60,000
miles).
1. REMOVE IGNITION COILS ASSEMBLIES
(See ignition coils removal)
2. INSPECT ELECTRODE
Using a megger (insulation resistance meter), measure the
insulation resistance.
Standard correct insulation resistance:
10 M or more
If the resistance is less than specified, proceed to step 4.
HINT: If a megger is not available, the following simple meth-
od of inspection provides fairly accurate results.
Simple Method:
(a) Quickly race the engine 5 times to 4,000 rpm.
(b) Remove the spark plug.
(c) Visually check the spark plug.
If the electrode is dry...OK
If the electrode is wet...Proceed to step 4
(d) Reinstall the spark plug.
3. REMOVE SPARK PLUGS
4. VISUALLY INSPECT SPARK PLUGS
Check the spark plug for thread damage and insulator dam-
age.
If abnormal, replace the spark plug.
Recommended spark plug:
ND
PK20R11
NGK
BKR6EP11
5. INSPECT ELECTRODE GAP
Maximum electrode gap for used spark plug:
1.3 mm (0.051 in.)
Correct electrode gap for new spark plug:
1.1 mm (0.043 in.)
NOTICE: If adjusting the gap of a new spark plug, bend only
the base of the ground electrode. Do not touch the tip. Never
attempt to adjust the gap on the used plug.

6. CLEAN SPARK PLUGS
If the electrode has traces of wet carbon, allow it to dry and
then clean with a spark plug cleaner.
Air pressure:
Below 588 kPa (6 kgf/cm
2, 85 psi)
Duration:
20 seconds or less
HINT: If there are traces of oil, remove it with gasoline before
using the spark plug cleaner.
7. REINSTALL SPARK PLUGS
Torque: 18 NVm (180 kgfVcm, 13 ftVlbf)
8. REINSTALL IGNITION COILS ASSEMBLIES
