SERVICE PROCEDURE

Check NATS On The Vehicle 

  1. Check to see if the vehicle you're working on has "ECM based" NATS V2.0 or V5.0.
    1. If the vehicle has ECM based NATS V2.0 or V5.0, it will NOT start after you install a service replacement ECM. So you'll have to re-register all ignition keys, including spare keys with CONSULT-II and the purple NATS card. After you do this, proceed with step 2.
      • If you do not know how to re-register the keys, refer to the ESM for the NATS key re-registration procedure.
    2. If the vehicle has "BCM based" NATS (instead of ECM based NATS V2.0 or V5.0), you do NOT have to re-register the ignition or spare keys. Proceed with step 2.

    Check For ECM Data Updates in ASIST 

  2. In ASIST, select [CONSULT Utilities] : [ECM/TCM Data]. Then choose Model and Model Year (see Fig 1 ).
    Fig 1: ECU Reprogramming Data Display
    G03360673
  3. Look for ECM Data Updates (listed by ECM P/N's and vehicle configuration) in the top, center display panel of the ASIST screen (see Fig 1 ).
    1. If there is no updates listed for your vehicle configuration, you do NOT have to reprogram the service replacement ECM. Proceed with step  5 (next page).
    2. If there is updates listed for your vehicle configuration, see if they apply to the service replacement ECM you're going to install. Do this by performing step 4 (next step).
  4. Select the "configuration" on the screen for the vehicle you're working on. Then confirm that your ECM is listed in the "Replaces 23710-XXXXX, -XXXXX, etc" section in the lower, center "Details" panel of the ASIST screen (see Fig 1 ).
    1. If your ECM is listed in the "Details" panel, you must reprogram the ECM with the latest data update. After you do this, proceed with step 5.
      • If you do not know how to reprogram the ECM, click here for the ECM Reprogramming Procedure or refer to Attachment A in the printed copy of this bulletin.
        CAUTION: The 1999-2000 Frontier and 1999-2000 Pathfinder have a gray CONSULT connector AND a white GST connector. Do NOT attempt to perform the ECM Reprogramming procedure with CONSULT-II connected to the gray CONSULT connector. See the appropriate ESM for further details if necessary.
    2. If your ECM is NOT listed in the "Details" panel, you do NOT have to reprogram the ECM. Proceed with step 5.

    Accelerator Pedal & Throttle Valve Closed Position Learning 

  5. Perform the Accelerator Pedal & Throttle Valve Closed Position Learning as follows:
    1. Make sure the accelerator pedal is fully released.
    2. Turn the ignition switch "ON" for 2 seconds.
    3. Turn the ignition switch "OFF" for 10 seconds.
    4. Turn the ignition switch "ON" for 2 seconds, then
    5. Turn the ignition switch "OFF" again for 10 seconds (see Fig 2 ).
    6. Proceed with step 6.

    Perform Idle Air Volume Learning (IAVL) 

    NOTE: Make sure all electrical loads are turned OFF, including A/C, defroster, radio, lights, etc. while performing the following procedures. Also, make sure the engine cooling fans are NOT operating during the following procedures.
  6. Perform the Idle Air Volume Learning procedure as follows:
    1. Connect CONSULT-II to the vehicle.
    2. Warm up engine and transmission to operating temperature.
    3. In the CONSULT WORK SUPPORT  mode, select IDLE AIR VOL LEARN.  See Fig 3 .
      NOTE:
      • If IDLE AIR VOL LEARN is not shown as a SELECT WORK ITEM on CONSULT, the vehicle does not need the procedure.
      • In this case only, this bulletin is complete, no further action is needed.

      • CONSULT will display "CMPLT" in the top right corner of the screen when the IAVL procedure is finished. See Fig 7 .
    6. Once the IAVL procedure is finished, proceed with step 7.
