EC-1161

< DTC/CIRCUIT DIAGNOSIS >

[MR EXCEPT FOR NISMO RS MODELS]

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.

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?

P2263 TC SYSTEM

DTC Logic

INFOID:0000000012198684

DTC DETECTION LOGIC

NOTE:

If DTC P2263 is displayed with DTC P0237 or P0238, first perform the trouble diagnosis for DTC P0237 or

P0238. Refer to

EC-938, "DTC Logic"

DTC CONFIRMATION PROCEDURE

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

>> Proceed to

EC-1164, "Diagnosis Procedure"

Component Function Check

INFOID:0000000012198685

INSPECTION START

Do you have CONSULT?
Do you have CONSULT?

YES

>> GO TO 2.

>> GO TO 3.

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
