10. Allow a 13-17mm (0.52-0.66 in) spacing between spark plug and
grounded metal portion as shown in the figure to fix the ignition
coil with a rope or an equivalent.
11. Crank the engine for approximately 3 seconds to see if sparking occurs between spark plug and the grounded metal portion.
CAUTION:
• The discharge voltage becomes 20 kV or higher. There-fore, always stay away from the spark plug and ignition
coil at least 50 cm (19.7 in) during the inspection.
• Leaving a space of more than 17mm (0.66 in) may damage
the ignition coil.
NOTE:
When the gap is less than 13 mm (0.52 in), a the sp ark might be generated even if the coil is mal-
functioning.
Is the inspection result normal?
YES >> GO TO 8.
NO >> GO TO 10.
8.CHECK COMPRESSION PRESSURE
Check compression pressure. Refer to EM-13, "
Inspection".
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
NO >> Check pistons, piston rings, valves, valve seats and cylinder head gaskets.
9.DETECT MALFUNCTIONING PART
Check fuel hoses and fuel tubes for clogging.
Is the inspection result normal?
YES >> Replace fuel filter and fuel pump assembly. Refer to FL-6, "Exploded View".
NO >> Repair or replace error-detected parts.
10.CHECK FUNCTION OF IGNITION COIL-2
1. Turn ignition switch OFF.
2. Disconnect spark plug and connect a non-malfunctioning spark plug.
3. Crank engine for approximately 3 seconds, and rec heck whether spark is generated between the spark
plug and the grounded metal portion.
Is the inspection result normal?
YES >> GO TO 11.
NO >> Check ignition coil, power transistor and their circuits. Refer to EC-451, "
Component Function
Check".
11 .CHECK SPARK PLUG
Check the initial spark plug for fouling, etc.
Is the inspection result normal?
YES >> 1. Repair or clean spark plug. Refer to EM-47,
"Exploded View".
2. GO TO 12.
NO >> Replace spark plug(s) with standard type one(s). For spark plug type, refer to EM-117, "
Spark Plug".
12.CHECK FUNCTION OF IGNITION COIL-3Spark should be generated.

Mechanism
It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the steel belt
(the steel plates are placed conti
nuously and the belt is guided with the multilayer steel rings on both sides).
The groove width changes according to wrapping radius of steel belt and pulley from low status to overdrive
status continuously with non-step. It is controlled with the oil pressures of primary pulley and secondary pulley.
Steel belt
It is composed of multiple steel plates (A) and two steel rings (B)
stacked to a several number. The feature of this steel belt transmits
power with compression of the steel plate in contrast with transmis-
sion of power in pulling with a rubber belt. Friction force is required
with the pulley slope to transmit power from the steel plate. The force
is generated with the following mechanism:
Oil pressure applies to the secondary pulley to nip the plate. ⇒The
plate is pushed and extended outward. ⇒The steel ring shows with-
stands. ⇒Pulling force is generated on the steel ring. ⇒ The plate of
the primary pulley is nipped between the pulley. ⇒Friction force is
generated between the steel belt and the pulley.
Therefore, responsibilities are divided by the steel plate that trans-
mits the power with compression and the steel ring that main tains necessary friction force. In this way, the
tension of the steel ring is distributed on the entire su rface and stress variation is limited, resulting in good
durability.
Pulley
The primary pulley (input shaft side) and the secondary pulley (output shaft side) have the shaft with slope
(fixed cone surface), movable sheave (movable cone surface that can move in the axial direction) and oil pres-
sure chamber at the back of the movable sheave.
Pulley gear shifting operation
• Pulley gear shifting operation The movable sheave slides on the shaft to change the groove width of the pulley. Input signals of engine
load (accelerator pedal opening), engine revolution and gear ratio (vehicle speed) change the operation
pressures of the primary pulley and the secondary pulle y, and controls the pulley groove width. Along with
change of the pulley groove width, the belt contact radi us is changed. This allows continuous and stepless
