Component Inspection (Ignition Coil with Power Transistor)

INFOID:0000000009947562

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 per the following.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace malfunctioning ignition coil with power transistor. Refer to 

EM-40, "Exploded View"

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.

Reconnect all harness connectors disconnected.

3.

Remove fuel pump fuse in IPDM E/R to release fuel pressure.
NOTE:
Do not use CONSULT to release fuel pressure, or fuel pressure applies again during the following proce-
dure.

4.

Start engine.

5.

After engine stalls, crank it two or three times to release all fuel pressure.

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.

Crank engine for 5 seconds or more 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. Crank engine for about three seconds, and check whether spark

is generated between the spark plug and the grounded metal
portion.

CAUTION:

• During the operation, always stay 0.5 cm (19.7 in) away

from the spark plug and the ignition coil. Be careful not to
get an electrical shock while checking, because the elec-
trical discharge voltage becomes 20 kV 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.

MALFUNCTION INDICATOR LAMP

Description

INFOID:0000000009947564

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-108, "DIAGNOSIS DESCRIPTION : Malfunc-

tion Indicator Lamp (MIL)"

.
