ECM REPROGRAMMING FOR NISSAN VEHICLES

1 1/18 Classification: Reference: Date: EC99-013d NTB00-006d May 12, 2006 ECM REPROGRAMMING FOR NISSAN VEHICLES This amended version (NTB00-006d) updates the Service Procedure Section. Please discard all previously released copies of NTB00-006. APPLIED VEHICLES :1999 Frontier (D22)1999 Quest (V41) Pathfinder (R50)All 2000 and later SERVICE INFORMATION In-vehicle ECM REPROGRAMMING is available to update the ECM of certain 1999 VEHICLES (listed in Applied VEHICLES above), and all 2000 and later VEHICLES . This REPROGRAMMING allows the vehicle ECM to be upgraded to the latest operating specifications without removal or replacement of the ECM. When an ECM has been reprogrammed it will display a new P/N on the CONSULT-II screen.

2 NOTE: ECM REPROGRAMMING will not affect NATS. ECM REPROGRAMMING requires the use of ASIST or higher, and CONSULT-II with the ECU REPROGRAMMING Software Card (orange color). Use the Service Procedure steps to transfer ECM REPROGRAMMING data from the ASIST PC to CONSULT-II, and from CONSULT-II to the vehicle ECM. Refer to the ECU REPROGRAMMING Software Operations Manual (in ASIST) for additional information on using CONSULT-II for ECM REPROGRAMMING . CAUTION An ECM should be reprogrammed only when required by a specific NISSAN Technical Bulletin, or as otherwise directed by NISSAN North America. The ECM can be permanently damaged if the REPROGRAMMING procedure is not followed exactly. Do not disturb (don t touch) the vehicle, CONSULT-II, or the DLC-II cable while ECM REPROGRAMMING is in progress. If the ECM is damaged, it must be replaced.

3 SERVICE PROCEDURE NOTE: When ECM REPROGRAMMING is required to repair a vehicle, a Technical Service Bulletin will be issued. ECM REPROGRAMMING involves two general steps: Download (transfer) data from ASIST into CONSULT-II. Download new data from CONSULT-II into the vehicle (Reprogram ECM). Before beginning the REPROGRAMMING procedure, use CONSULT-II and the Diagnostic Card (red/white one) to retrieve any stored DTC(s). Additional repairs may be necessary if there are DTC(s) not associated with a REPROGRAMMING bulletin. Refer to the appropriate TSB or Service Manual. SETTING UP: TP010647 Make sure card is fully seatedInsert card into slot A (top) Figure 1 2a. Connect the AC power supply to CONSULT-II. 2b. Connect CONSULT-II to the ASIST PC with the special Ethernet cable (P/N 02002554 is printed on the cable). Connect one end to CONSULT-II at the PC port.

4 Connect the other end to the ASIST PC at the Ethernet card connection port. 3. 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. 1. Install the REPROGRAMMING Card into CONSULT-II. The REPROGRAMMING Software Card is the orange Card. Use slot A top slot (see Figure 1). 2/18 BACKLIGHTCOPYTP990902 VERSIONSET DATESUB MODESET TIMEDOWNMODECONFIGURE ETHERNETCOMMUNICATIONS TESTLCD TEST Figure 2 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.

5 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 4. 4. Set the Ethernet (IP) Address of the ASIST PC and CONSULT-II as follows: NOTE: If your ASIST terminal has been used to perform ECM REPROGRAMMING before, you may skip steps "A" through "I" below and proceed to step 5 on page 5. If you are unsure whether your ASIST terminal has been already set up for ECM REPROGRAMMING , proceed to step "A" below.

Compare Figure 4 with the "TCP/IP PROPERTIES" screen on the ASIST PC. If the "IP ADDRESS" and "SUBNET MASK" appear EXACTLY as shown in Figure 4, click "CANCEL" and close the "CONTROL PANEL" box.

7 Now continue to step "D". If the "IP ADDRESS" and "SUBNET MASK" do not match EXACTLY as shown in Figure 4, change the numbers so that they do. Click "OK", reboot the computer to save the new IP Address, and continue to step "D". D. On CONSULT-II Touch CONFIGURE ETHERNET. E. Check that the Ethernet (IP) Address is and the Mask is (see Figure 5). If the Ethernet (IP) Address already matches the address listed in step "E" above, press COPY to print the Address for future reference, turn off CONSULT-II and proceed with step 5 below. If the Ethernet (IP) Address does not match the address listed in step "E" above, proceed with step "F" below to correctly set the CONSULT-II Ethernet (IP) address. F. To change, touch the Address number on the CONSULT-II screen (titled "Configure Ethernet"). A numeric keypad will appear (see Figure 6). G. Use the keypad to change the Address and Mask to the correct number.

8 H. Touch SAVE and then press COPY to print the Address for future reference. I. Turn off CONSULT-II to allow the new address to be saved in memory, then proceed with step 5. 4/18 DOWNLOAD (TRANSFER) DATA FROM ASIST INTO CONSULT-II 5.
