Description

When replacing ECM, the following procedure must be performed. (For details, refer to Work Procedure.)

CAUTION:

When replacing the ECM, always replace it with a new one. The functions controlled by the ECM does not operate properly in case of reuse of the ECM from another Nissan Murano vehicle.

PROGRAMMING OPERATION

NOTE:

After replacing with a blank ECM, programming is required to write ECM information. Be sure to follow the procedure to perform the programming.

Work Procedure (Before Replacing ECM)

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.

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)

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 Nissan Murano 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?

GO TO 2.

GO TO 3.

PERFORM ECM PROGRAMMING

With CONSULT

Perform ECM programming, according to “Programming” of CONSULT Operation Manual. Refer to CONSULT Operation Manual.

CAUTION:

During programming, maintain the following conditions:

GO TO 5.

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 ECU part number from NISSAN PARTS CATALOGUE GLOBAL Web-FAST even when the part number cannot be obtained from the old ECU used before replacing with a new one.

GO TO 4.

PERFORM 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:

GO TO 5.

PERFORM INITIALIZATION OF IVIS (NATS) SYSTEM AND REGISTRATION OF ALL IVIS (NATS) IGNITION KEY IDS

Refer to Work Procedure.

GO TO 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?

GO TO 7.

GO TO 8.

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.

PERFORM VIN REGISTRATION

Refer to Description.

GO TO 9.

PERFORM ACCELERATOR PEDAL RELEASED POSITION LEARNING

Refer to Description.

GO TO 10.

PERFORM THROTTLE VALVE CLOSED POSITION LEARNING

Refer to Description.

GO TO 11.

PERFORM IDLE AIR VOLUME LEARNING
