CHECK FUNCTION OF IGNITION COIL-1
CAUTION:
Perform the following steps in a well-ventilated area with no combustibles.
1. Turn ignition switch OFF.
2. Remove fuel pump fuse from IPDM E/R to release fuel pressure.
NOTE:
CONSULT must not be used to release fuel pressure. It develops again during the following steps,
if released by using CONSULT.
3. Start the engine.
4. After an engine stall, crank the engine two or three times to release all the fuel pressure.
5. Turn ignition switch OFF.
6. Disconnect all the harness connectors of ignition coil to prevent electric discharge from occurring in igni-
tion coil.
7. Remove ignition coil assembly and spark plug of cylinder. Refer to
EM-214, "Removal and Installation"
8. Crank engine for 5 seconds or more to remove combustion gas in the cylinder.
9. Connect spark plug and harness connector to ignition coil.
10. Allow a 13-17mm (0.52-0.66 in) spacing between spark plug and
grounded metal portion as shown in the figure to fix the ignition
coil with a rope or an equivalent.
11. Crank the engine for approximately 3 seconds to see if sparking
occurs between spark plug and the grounded metal portion.
CAUTION:
• The discharge voltage becomes 20 kV or higher. There-
fore, always stay away from the spark plug and ignition
coil at least 50 cm (19.7 in) during the inspection.
• Leaving a space of more than 17mm (0.66 in) may damage
the ignition coil.
NOTE:
When the gap is less than 13 mm (0.52 in), a the spark might be generated even if the coil is mal-
functioning.
Is the inspection result normal?
YES
>> GO TO 7.
NO
>> GO TO 9.
7.
CHECK COMPRESSION PRESSURE
Check compression pressure. Refer to
Is the inspection result normal?
YES
>> Check intermittent incident. Refer to
GI-45, "Intermittent Incident"
.
NO
>> Check pistons, piston rings, valves, valve seats and cylinder head gaskets.
8.
DETECT MALFUNCTIONING PART
Check fuel hoses and fuel tubes for clogging.
Is the inspection result normal?
YES
>> Replace fuel filter and fuel pump assembly. Refer to
or
(AWD models).
NO
>> Repair or replace error-detected parts.
9.
CHECK FUNCTION OF IGNITION COIL-2
1. Turn ignition switch OFF.
2. Disconnect spark plug and connect a non-malfunctioning spark plug.
3. Crank engine for approximately 3 seconds, and recheck whether spark is generated between the spark
plug and the grounded metal portion.
Is the inspection result normal?
Spark should be generated.
JMBIA0066GB
Spark should be generated.

>> Replace spark plug(s) with standard type one(s). For
spark plug type, refer to
.
11.
CHECK FUNCTION OF IGNITION COIL-3
1. Reconnect the initial spark plugs.
2. Crank engine for approximately 3 seconds, and recheck whether spark is generated between the spark
plug and the grounded portion.
Is the inspection result normal?
YES
>> Check intermittent incident. Refer to
GI-45, "Intermittent Incident"
.
NO
>> Replace spark plug(s) with standard type one(s). For spark plug type, refer to
.
SEF156I
Spark should be generated.

DTC CONFIRMATION PROCEDURE
1.
PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to
EC-1163, "Component Function Check"
NOTE:
Use component function check to check the overall function of the turbocharger system circuit. During this
check, a 1st trip DTC might not be confirmed.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Proceed to
EC-1164, "Diagnosis Procedure"

INSPECTION START
Do you have CONSULT?
Do you have CONSULT?
YES
>> GO TO 2.
NO
>> GO TO 3.
2.
CHECK ELECTRIC WASTEGATE CONTROL ACTUATOR
With CONSULT
1. Turn ignition switch ON and engine stopped.
2. On the CONSULT screen, select “ENGINE” >> “ACTIVE TEST” >> “WASTEGATE ACTUATOR”.
3. Operate “Up” or “Down”, set “W/G ACTUATOR POSITION B1” to 0.002 m, and make a quick short note of
value “V1” of “W/G ACTUATOR POSI SEN B1”.
4. Operate “Up” or “Down”, set “W/G ACTUATOR POSITION B1” to 0.006 m, and make a quick short note of
value “V2” of “W/G ACTUATOR POSI SEN B1”.
Do the values of “V1” and “V2” change (visually, ACTUATOR SHAFT operates) and “V2” minus “V1” becomes
equal to or more than 1.3V?
YES
>> INSPECTION END
NO
>> Refer to
EC-1164, "Diagnosis Procedure"
