IGNITION COIL INSPECTION

A3U011818100W02

Igniter

•

Carry out spark test. (See 01–03A–60 Spark Test.) (See 01–03B–59 Spark Test.)

Ignition Coil Operation Inspection

1. Remove ignition coils, high-tension leads, and spark plugs.
2. Connect the ignition coil, high-tension lead, spark 

plug, and the battery as shown in the figure.

Caution

••••

When connecting the ignition coil, be 
sure to attach as a female terminal to 
each terminal. Otherwise, coil terminals 
may come into contact and the ignition 
coil could be damaged.

Note

•

Use the high-tension lead and spark plug 
that function properly.

3. Verify that the spark plug produces a strong, pale 

spark when change the switch off to on.

Warning

••••

Do not hold the spark plug, high-tension 
lead, or ignition coil while inspecting the 
ignition coil. You may be subjected to a 
strong shock.

Note

•

No.1 and No.4 cylinders and No.2 and No.3 
cylinder are ignited simultaneously.

Secondary Coil Winding

1. Remove the ignition coil.
2. Measure the resistance from lead hole 1 to 4, and lead hole 2 to 3 using an ohmmeter.

•

If not as specified, replace the ignition coil.

Specification

ZM 8.0—12.0 kilohms
FS 7.2—10.8 kilohms

Insulation Resistance of Case

1. Disconnect the high-tension lead. (See 01–18–3 HIGH-TENSION LEAD REMOVAL/INSTALLATION.)
2. Disconnect the ignition coil connector.
3. Measure the insulation resistance from terminal 1A to ignition coil case, and terminal 2A to ignition coil case 

using an ohmmeter.

•

If not as specified, replace the ignition coil.

HIGH-TENSION LEAD REMOVAL/INSTALLATION

A3U011818140W01

Caution

••••

The high-tension leads must be reinstalled to their original positions. Incorrect installation can 
damage the leads and cause power loss, and negatively affect the electronic components.

HIGH-TENSION LEAD INSPECTION

A3U011818140W02

1. Measure the resistance of the high-tension leads 

using an ohmmeter.

Warning

••••

When the battery cables are connected, touching the vehicle body with starter terminal B will 
generate sparks. This can cause personal injury, fire, and damage to the electrical components. 
Always disconnect the battery before performing the following operation.

1. Disconnect the negative battery cable.
2. Remove the battery.
3. Remove the intake manifold bracket.
4. Remove in the order indicated in the table.
5. Install in the reverse order of removal.

STARTER INSPECTION

A3U011918400W02

On-Vehicle Inspection

1. Verify that the battery is fully charged.
2. Crank the engine and verify that the starter rotates smoothly without any noise.
3. Measure the voltage at terminals S and B when the ignition switch is at START position.

•

If the voltage is within the specification, remove the starter and inspect the magnetic switch and the starter.

•

If the voltage is not as specified, inspect the wiring harness, ignition switch, starter interlock switch (MTX), 
and transaxle range switch (ATX).

Specification

Above 8 V

No Load Test

1. Verify that the battery is fully charged.
2. Connect the starter, battery, voltmeter and 

ammeter as shown.

3. Operate the starter and verify that it rotates 

smoothly.

4. Measure the voltage and current while the starter 

is operating.

•

If not as specified, repair or replace the starter 
as necessary.

Specification

Voltage: 11 V
Current: below 90 A

STARTER INTERLOCK SWITCH INSPECTION (MTX)

A3U011943440W01

On-vehicle Inspection

1. With the clutch pedal not depressed, verify that the engine does not start.
2. With the clutch pedal fully depressed, verify that the engine starts.

•

If the above cannot be verified, carry out continuity inspection.

Continuity Inspection

1. Disconnect the starter interlock switch connector.
2. Inspect for continuity between terminals of the starter interlock switch using an ohmmeter.

•

If not as specified, replace the starter interlock switch.
