Service Procedure
NATS C/U Initialization With 4-Digit PIN Code and Key Registration^ It is highly recommended that you read through the entire service procedure before doing it for the first time.
1st step; Prepare
1. Collect all existing ignition keys from the customer.
Note:
ANY KEYS THAT ARE NOT REGISTERED AT THIS TIME WILL NO LONGER START THE VEHICLE.
2. Separate all NATS ignition keys and other transponders away from each other.
^ Take them off the key ring.
^ You must keep them separate during the whole key registration process.
2nd step; Get the "BCM-specific" 5-Digit Number Code
350Z
1a. Locate the Body Control Module (BCM). The BCM is located behind drivers side left kick panel (see Figure 4a).
Murano
1b. Locate the Body Control Module (BCM). The BCM is located behind drivers side lower knee panel (see Figure 4b).
2. Write down the BCM-specific 5-digit number code (see Figure 4a & 4b). The letter "O" is not used in the 5-digit number code. Anything that looks like an "O" is really the number zero "0".
3. Go to an ASIST terminal.
3rd step; Decode the number
1. From the ASIST Main Menu screen, click on "Information Tool Box."
2. From the "Information Tool Box" screen, click on "NATS Decoder" button (see Figure 5).
3. Follow the steps in Figure 6, shown.
NOTE:
^ If you need help while in the IVIS/NVIS (NATS) screen, you can click the "HELP" (?) button to view an example of the BCM label (see Figure 6).
^ The letter "O" is not used in the 5-digit number code. Anything that looks like an "O" is really the number zero "0".
4th step; C/U Initialization Procedure
1. Insert the NATS (Purple) Software Card into Slot A of the CONSULT-II unit.
2. Connect CONSULT-II and CONSULT-II converter to the data link connector under the dash.
3. Insert the ignition key into the ignition and turn it to the "ON" position.
^ Do not start the engine.
^ CONSULT-II will load the NATS software automatically.
^ Wait for the START box to appear on CONSULT-II before proceeding.
4. Touch [START] on the CONSULT-II screen.
5. Touch [NATS V 5.0].
6. Touch [C/U INITIALIZATION] to perform C/U INITIALIZATION mode.
7. On the CONSULT-II "IMMU INITIALIZATION" touch screen:
^ Type in the 4-digit PIN Code Number.
^ You wrote it down from ASIST IVIS/NVIS (NATS) screen (step 3, in 3rd step; Decode the number).
8. Touch [START] on CONSULT-II to perform C/U INITIALIZATION.
9. When C/U INITIALIZATION is complete for the BCM;
a. "INITIALIZATION COMPLETED" will be "displayed" on the IMMU INITIALIZATION screen.
b. Turn key to "OFF/LOCK" position and pull it out.
c. WAIT AT LEAST 5 SECONDS.
d. Go to 5th step; Key Registration.
NOTE:
The key that you just used is NOT registered yet.
5 step; Key Registration
1. Insert a key into the ignition and turn it to the "ON" position.
Do not start the engine.
2. Wait at least 5 seconds (the Security Lamp will flash 5 times, then it will stop).
3. Turn the key to "OFF/LOCK" and remove it.
^ The key is now registered.
^ Keep it separate from the other keys.
IMPORTANT:
Keep the first REGISTERED key separate from ALL the other keys for right now. DO NOT MIX UP KEYS!
NOTE:
^ The first registered key will be used later in step 4 (below). Keep it separate from all other keys.
^ Keep the "registered" keys and the "unregistered" keys in different "piles during this process.
^ Accidentally inserting an already "registered" key into the ignition at this point will drop the system out of the registration mode.
^ If this happens you will have to start all over again. Go back to # 1 of 4th step (C/U Initialization); and restart from there.
4. Repeat steps 1, 2 and 3 for all remaining "unregistered" keys.
^ Remember, a maximum of five keys can be registered into the system.
5. After registering and removing the last key;
^ Re-insert the first registered key and
^ turn the key to the "ON" position for 5 seconds.
^ This will take the system out of the key registration mode.
NOTE:
The Security Lamp will not flash during this 5 second period.
6. Turn the key to the "OFF" position.
7. Wait for the Security Lamp to start blinking (approximately 5 seconds).
^ This indicates the completion of Key ID Registration and "C/U Initialization."
^ Proceed to Key Confirmation (Step 6).
NOTE:
On the CONSULT-II screen: If "INITIALIZATION STOPPED" or "INITIALIZATION FAIL" is displayed during the above procedure:
A. Repeat 2nd step: "Get the 'BCM-specific' 5-Digit Number Code."
B. Repeat 3rd step: "Decode the Number."
^ This is to confirm that you wrote down the correct BCM-specific 5-digit number code and "generated"/wrote down the correct 4-digit PIN Code Number.
C. Turn the ignition switch "OFF", then "ON".
D. Check "SELF-DIAG RESULTS". Refer to the "BL" section in the Electronic Service Manual (ESM) for any stored codes.
E. Once "NO SELF DIAGNOSIS FAILURE INDICATED" is displayed:
^ Repeat 4th step; "C/U Initialization" and 5th step; "Key Registration" again. Then, proceed to 6th step; "Key Confirmation" (below).
6th step; Key "Confirmation" (check)
1. Confirm that the Security Indicator Lamp on the dash is blinking.
^ This verifies the completion of the Key ID Registration procedure.
2. Confirm all keys operate (start the engine) as follows:
a. Start the engine.
b. Turn the ignition OFF and remove the key.
c. Watch and wait for the Security Indicator Lamp to begin blinking (approximately 5 seconds).
^ This indicates the system has reset.
^ You must wait for the system to reset between key checks or key operation will not be confirmed.
d. Start the engine using the next key.
e. Repeat steps a - c for all keys that were registered.
3. Press [BACK] on the CONSULT-II screen.
4. Press [BACK] on the CONSULT-II screen again.
5. Put any registered key into the ignition and turn it to the "ON" position.
6. Select [SELF-DIAGNOSIS RESULTS] to check for DTC's.
^ In rare cases "CHAIN OF ECM-IMMU" or other DTC's may be stored during the Key Registration process.
^ If DTC's are stored, press [ERASE] to clear them.
7. Turn the ignition to "LOCK" and remove the key.
8. Turn CONSULT-II OFF and disconnect it from the vehicle.
