2007 NISSAN TIIDA EC Engine Control System

EC-1054
< BASIC INSPECTION >[K9K]
INSPECTION AND ADJUSTMENT
- All the electrical loads are switched off.
- Air conditioning is switched off.
CAUSE
- The engine runs poorly at idle speed, possibly emits white smoke.
1.CHECK FUEL INJECTOR
Refer to EC-1141, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace malfunctioning fuel injector.
2.CHECK ENGINE COOLANT TEMPERATURE AND FUEL TEMPERATURE
1. Start engine let it idle speed.
2. Select “DATA MONITOR” mode with CONSULT-III.
3. Check “FUEL TEMP” indication is above 60°C (140°F)
4. Check “F/FLOW CORR CYL1“, “F/FLOW CORR CYL2”, “F/FLOW CORR CYL3”, “F/FLOW CORR CYL4”
indication.
Are the reference value 0.3 - 1.9?
YES >> GO TO 3.
NO >> GO TO 4.
3.CHECK INTERNAL FUEL TRANSFER PUMP
1. Turn ignition switch OFF.
2. Disconnect the return system connections at the fuel injectors and close off the return pipes so they are
leak-tight. While the engine is idling, check the return flow rate at the fuel injector. After 5 minutes the
return volume must be between 16 - 24 ml per fuel injector.
Is there more than 24 ml or less than 16 ml of return for each fuel injector?
Yes >> Replace malfunctioning fuel injector.
No >> INSPECTION END
4.CHECK COMPRESSION PRESSURE
Check compression pressure. Refer to EM-267, "
Inspection".

1.PRECONDITIONING
 Connect a CONSULT-III
 Connect a battery charger
 Electric load switch is OFF
 Wait for the engine to cool [engine coolant temperature < 60°C (140°F and air temperature < 50°C (122°F)].
NOTE:
While the ECM is being programmed the cooling fan motors are triggered automatically.
>> GO TO 2.
2.SAVE ECM DATA
Turn ignition switch ON.
Perform “SAVE DATA FOR CPU REPLC” in WORK SUPPORT mode with CONSULT-III.

4.WRITE ECM DATA
1. Turn ignition switch OFF, wait at least 30 seconds and then turn ON.
2. Perform “PRGRM REINITIALIZE” in WORK SUPPORT mode with CONSULT-III.
3. Perform “WRT DATA AFTR REPLC CPU” in WORK SUPPORT mode with CONSULT-III.
4. Perform initialization of NATS system and registration of all NATS ignition key IDs.
Refer to SEC-7, "
ECM RE-COMMUNICATING FUNCTION : Description" (with intelligent key system) or
SEC-83, "
ECM RE-COMMUNICATING FUNCTION : Description" (without intelligent key system).
5. Turn ignition switch OFF, wait at least 30 seconds and then turn ON.
6. Select “DATA MONITOR” mode in ECM with CONSULT-III.
7. Check that the “CODE PROGRAM” indication.
Which is displayed on CONSULT-III?
YES >> GO TO 6.
NO >> GO TO 5.
5.WRITE ECM DATA
1. Perform initialization of NATS system and registration of all NATS ignition key IDs.
Refer to SEC-7, "
ECM RE-COMMUNICATING FUNCTION : Description" (with intelligent key system) or
SEC-83, "
ECM RE-COMMUNICATING FUNCTION : Description" (without intelligent key system).
2. Turn ignition switch OFF, wait at least 30 seconds and then turn ON.
3. Select “DATA MONITOR” mode in ECM with CONSULT-III.
4. Check that the “CODE PROGRAM” indication.
Which is displayed on CONSULT-III?
YES >> GO TO 6.
NO >> Repeat above steps.
6.PERFORM VIN REGISTRATION
1. Start engine and warm it up to normal operating temperature.
NOTE:
The start-up phase may last up to 30 seconds.
2. Turn ignition switch OFF, wait at least 30 seconds and then turn ON.
3. Perform “VIN REGISTRATION” in WORK SUPPORT mode with CONSULT-III.
4. Follow the instruction of CONSULT-III display.
NOTE:
After replace ECM, stored DTC may appear on other control unit. Clear the malfunction memory of these
control unit.
