Work Procedure

Work Procedure (Before Replacing ECM) 

1. SAVE ECM DATA 

   With CONSULT

   1. Turn ignition switch OFF.
   2. Reconnect all harness connectors disconnected.
   3. Turn ignition switch ON.
   4. Select "SAVING DATA FOR REPLC CPU" in "WORK SUPPORT" mode of "ENGINE" using CONSULT.
   5. Follow the instruction of CONSULT display.
   NOTE:

   • Necessary data in ECM is copied and saved to CONSULT.
   • Go to Step 2 regardless of with or without success in saving data.

   GO TO 2.

2. SAVE "OPERATION LOG" 

   With CONSULT

   Save Operation Log, according to the procedure of "Programming" in CONSULT Operation Manual.

   NOTE: ECM part number is saved in Operating Log saved in CONSULT.
   • Replace ECM.
   • After replacing ECM, perform necessary work.

Work Procedure (After Replacing ECM) 

1. CHECK "OPERATION LOG" 

   With CONSULT

   Check Operation Log saved before replacing ECM, according to the procedure of "Programming" in CONSULT Operation Manual.

   NOTE: For the vehicle that the programming is to be performed, check if Operation Log of Vehicle Identification Number (VIN) is in Saved Data List.

   Is there an applicable Operation Log in the Saved Data List?

   YES

   GO TO 2.

   NO

   GO TO 3.

2. PERFORM ECM PROGRAMMING 

   After replacing ECM, perform the ECM programming. Refer to CONSULT Operation Manual.

   NOTE:

   • Refer to Removal and Installation for replacement of ECM.

   • During programming, maintain the following conditions:
     • Ignition switch: ON
     • Electric load: OFF
     • Brake pedal: Not depressed
     • Battery voltage: 12 - 13.5 V (Be sure to check the value of battery voltage by selecting "BATTERY VOLT" in "Data monitor" of CONSULT.)

   GO TO 5.

3. READ IN ECM PART NUMBER BY "FAST LINKED" 

   Obtain ECM part number by NISSAN PARTS CATALOGUE GLOBAL Web-FAST, according to the procedure of "FAST linked" in CONSULT Operation Manual. Refer to CONSULT Operation Manual.

   NOTE: "FAST linked" allows an appropriate programming by obtaining ECM part number from NISSAN PARTS CATALOGUE GLOBAL Web-FAST even when the part number cannot be obtained from the old ECM used before replacing with a new one.

   GO TO 4.

4. PERFORM ECM PROGRAMMING (FAST LINKED) 

   With CONSULT

   Perform ECM programming according to the procedure of FAST linked in CONSULT Operation Manual. Refer to CONSULT Operation Manual.

   CAUTION: During programming, maintain the following conditions:

   • Ignition switch: ON
   • Electric load: OFF
   • Brake pedal: Not depressed
   • Battery voltage: 12 - 13.5 V (Check the value displayed on the CONSULT screen.)

   GO TO 5.

5. PERFORM INITIALIZATION OF NATS SYSTEM AND REGISTRATION OF ALL NATS IGNITION KEY IDS 

   Refer to Description .

   GO TO 6.

6. CHECK ECM DATA STATUS 

   Check if the data is successfully copied from the ECM at Step 1 (before replacement) and saved in CONSULT.

   Is the data saved successfully?

   YES

   GO TO 7.

   NO

   GO TO 8.

7. WRITE ECM DATA 

   With CONSULT

   1. Select "WRITING DATA FOR REPLC CPU" in "WORK SUPPORT" mode of "ENGINE" using CONSULT.
   2. Follow the instruction of CONSULT display.
   NOTE: The data saved by "SAVING DATA FOR REPLC CPU" is written to ECM.

   GO TO 9.

8. PERFORM VIN REGISTRATION 

   Refer to Description .

   GO TO 9.

9. PERFORM ACCELERATOR PEDAL RELEASED POSITION LEARNING 

   Refer to Description .

   GO TO 10.

10. PERFORM THROTTLE VALVE CLOSED POSITION LEARNING 

    Refer to Description .

    GO TO 11.

11. PERFORM IDLE AIR VOLUME LEARNING 

    Refer to Description .
