Component Inspection (Ignition Coil with Power Transistor)

INFOID:0000000004211644

1.

CHECK IGNITION COIL WITH POWER TRANSISTOR-I

1. Turn ignition switch OFF.

2. Disconnect ignition coil harness connector.

3. Check resistance between ignition coil terminals as follows.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace malfunctioning ignition coil with power transis-

tor.

2.

CHECK IGNITION COIL WITH POWER TRANSISTOR-II

CAUTION:

Do the following procedure in the place where ventilation is good without the combustible.

1. Turn ignition switch OFF.

2. Remove fuel pump fuse in IPDM E/R to release fuel pressure.

NOTE:

Do not use CONSULT-III to release fuel pressure, or fuel pressure applies again during the following pro-

cedure.

3. Turn ignition switch ON (READY).

4. Depress accelerator pedal and keep it.

5. After engine stalls, check DTC.

If DTC is detected, erase DTC and go to next steps.

If DTC is not detected, go to next steps.

6. Turn ignition switch OFF.

7. Remove all ignition coil harness connectors to avoid the electrical discharge from the ignition coils.

8. Remove ignition coil and spark plug of the cylinder to be checked.

9. Repeat steps 3 to 5 for two or three times to remove combustion gas in the cylinder.

10. Connect spark plug and harness connector to ignition coil.

11. Fix ignition coil using a rope etc. with gap of 13 - 17 mm (0.52 -

0.66 in) between the edge of the spark plug and grounded metal

portion as shown in the figure.

12. Turn ignition switch ON (READY).

13. Depress accelerator pedal for about 3 seconds, and check

whether spark is generated between the spark plug and the

grounded metal portion.

CAUTION:

• Do not approach to the spark plug and the ignition coil

within 50 cm (19.7 in). Be careful not to get an electrical

shock while checking, because the electrical discharge voltage becomes 20kV or more.

• It might cause to damage the ignition coil if the gap of more than 17 mm (0.66 in) is taken.

NOTE:

When the gap is less than 13 mm (0.52 in), the spark might be generated even if the coil is mal-

functioning.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace malfunctioning ignition coil with power transistor.

Component Inspection (Condenser-2)

INFOID:0000000004211645

1.

CHECK CONDENSER-2

1. Turn ignition switch OFF.

2. Disconnect condenser-2 harness connector.

3. Check resistance between condenser-2 terminals as follows.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace condenser-2.

MALFUNCTION INDICATOR LAMP

Description

INFOID:0000000004211646

The Malfunction Indicator Lamp (MIL) is located on the combination

meter.

The MIL will light up when the ignition switch is turned ON without

the engine running. This is a bulb check.

When the engine is started, the MIL should go off. If the MIL remains

on, the on board diagnostic system has detected an engine system

malfunction.

For details, refer to 

EC-395, "Diagnosis Procedure"

.
