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

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
.
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
.
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
.
Diagnosis Procedure
INFOID:0000000012198104

COOLING FAN
COOLING FAN
Component Function Check
INFOID:0000000012198105
1.
CHECK COOLING FAN FUNCTION
With CONSULT
1. Turn ignition switch ON.
2. Perform “FAN DUTY CONTROL” in “ACTIVE TEST” mode of “ENGINE” using CONSULT.
3. Check that cooling fan speed varies according to the percentage.
Without CONSULT
1. Activate IPDM E/R auto active test and check cooling fan motors operation. Refer to
.
2. Check that cooling fan operates.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Proceed to
.
Diagnosis Procedure
INFOID:0000000012198106
1.
CHECK COOLING FAN CONTROL MODULE POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect cooling fan control nodule harness connector.
3. Turn ignition switch ON.
4. Check the voltage between cooling fan control nodule harness connector and ground.
Is the inspection result normal?
YES
>> GO TO 5.
NO
>> GO TO 2.
2.
CHECK COOLING FAN CONTROL MODULE POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
