Reprogramming The ECM
REPROGRAMMING THE ECMReprogramming should be performed by an OBDII Certified technician.
The reprogramming procedure involves three general steps:
^ Setting up
^ Download (transfer) data from ASIST into CONSULT-II.
^ Download new data from CONSULT-II into the vehicle (Reprogram the ECM).
SETTING UP:
1. Install the Reprogramming Card into CONSULT-II.
^ Make sure CONSULT-II is disconnected from the vehicle and turned OFF.
^ The reprogramming Software card is the "orange" Card.
^ Use slot A - top slot (See Figure 1).
2. Connect the AC power supply to CONSULT-II.
3. Connect CONSULT-II to the ASIST PC with the special Ethernet cable (P/N 02002554 is printed on the cable).
A. Connect one end to CONSULT-II at the "PC port".
B. Connect the other end to the ASIST PC at the "Ethernet card" connection port.
4. Confirm the CONSULT-II date and time are correctly set as follows:
(This is necessary to provide a valid print-out for warranty claims.)
A. With the Reprogramming card in slot A, turn "ON" CONSULT-II.
B. Touch [SUB MODE].
C. Touch [SET DATE] (see Figure 2).
1) If the date is not correct, touch the [MONTH], [DAY] or [YEAR] as needed. Then adjust it by using arrow keys. Once done, press [SAVE], press [BACK], and go to step D.
2) If the date is OK, press [BACK] and go to step D.
D. Touch [SET TIME] (see Figure 2).
1) If time is not correct, touch the [HOUR], [MINUTE] or [AM/PM] as needed. Then adjust it by using arrow keys. Once done, press [SAVE], press [BACK] and go to step 5.
2) If time is OK, press [BACK] and go to step 5.
IMPORTANT NOTE:
^ If your ASIST PC is already being used to perform ECM Reprogramming, proceed to step 5 below.
^ If you are unsure whether your ASIST PC has already been set up for ECM Reprogramming, look in ASIST, under "CONSULT Utilities" - "CONSULT-II Info" - "NISSAN" - "ECU Reprogramming". This will give you instructions for setting the Ethernet (IP) Address of the ASIST PC and CONSULT-II. You will need to do this before performing ECM reprogramming.
DOWNLOAD (TRANSFER) DATA FROM ASIST INTO CONSULT-II
5. From the ASIST PC main menu screen, select "CONSULT UTILITIES" (see Figure 3).
6. From the "CONSULT UTILITIES" screen, select "ECM / TCM DATA" (see Figure 4).
7. Select the "ECU REPROGRAMMING DATA" (see Figure 5) as follows:
A. Select vehicle model and model year.
B. Select the correct reprogramming data:
1) Locate the specific "Model Configuration" (Example: QR25 A/T ASCD).
NOTE:
^ Model Configuration may include items like engine type, transmission type, and vehicle options such as ASCD, TCS, ABS, etc.
^ Vehicle configuration can be verified using the "Current ECM P/N" in Chart A.
2) Select (click on) the "To" number.
NOTE:
The "To" number reads: 23710-XXXXX.
3) Write the "To" number on the Repair Order. You will need it later in the reprogramming process.
C. Click on the "Add" button to add data to the "File(s) selected" list. This list is on the right side of the screen.
D. Click the "CONTINUE" button to proceed with CONSULT-II setup.
8. Turn "ON" CONSULT-II as shown in Figure 6.
9. Select [Transfer files via LAN] (see Figure 7).
NOTE:
If you accidentally choose a menu option other than "Transfer Files via LAN"; turn CONSULT-II "OFF", and then back "ON" as shown in Figure 6 above.
Set the CONSULT-II unit down for now and go to your ASIST PC.
10. Transfer (download) data from ASIST into CONSULT-II.
A. On the ASIST screen, click on "Transfer" (see Figure 8).
^ Data transfer will take about 15 seconds.
^ Transfer progress is displayed on the ASIST screen (see Figure 8).
B. Wait until the data transfer is complete (see CAUTION below).
CAUTION:
DO NOT DISCONNECT THE ETHERNET CABLE UNTIL "COMPLETE" IS DISPLAYED AS SHOWN IN FIGURE 9 ABOVE.
11. When transfer is complete (see Figure 9):
A. Select (click on) "Okay", then "MAIN MENU".
B. Turn "OFF" CONSULT-II.
C. Disconnect the AC power cord and the Ethernet cable from CONSULT-II.
