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. Refer

to 

EM-60, "Exploded View"

.

8. Remove ignition coil and spark plug of the cylinder to be checked. Refer to .0

EM-60, "Exploded View"

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.

Is the inspection result normal?

YES

>> INSPECTION END

NO

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

EM-60, "Exploded View"

ELECTRICAL LOAD SIGNAL

ELECTRICAL LOAD SIGNAL

Description

INFOID:0000000012198102

The electrical load signal (Headlamp switch signal, rear window defogger switch signal, etc.) is transferred via

the CAN communication line.

Component Function Check

INFOID:0000000012198103

1.

CHECK REAR WINDOW DEFOGGER SWITCH FUNCTION

With CONSULT

1. Turn ignition switch ON.

2. Select “DATA MONITOR” mode of “ENGINE” using CONSULT.

3. Select “LOAD SIGNAL” and check indication as per the following conditions.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Proceed to 

EC-558, "Diagnosis Procedure"

.

2.

CHECK LIGHTING SWITCH FUNCTION

With CONSULT-III

Check “LOAD SIGNAL” indication as per the following conditions.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Proceed to 

EC-558, "Diagnosis Procedure"

.

3.

CHECK HEATER FAN CONTROL SWITCH FUNCTION

With CONSULT

Select “HEATER FAN SW” and check indication as per the following conditions.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Proceed to 

EC-558, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000012198104

1.

INSPECTION START

Confirm the malfunctioning circuit (rear window defogger, headlamp or heater fan). Refer to 

EC-558, "Compo-

nent Function Check"

.

Which circuit is related to the incident?

Rear window defogger>>GO TO 2.

Headlamp>>GO TO 3.

Heater fan>>GO TO 4.
