Service Procedure

1. Remove the air filter element. Then, vacuum out all dust/dirt/debris found inside both halves of the air filter housing.

CAUTION:
Make sure all dust/dirt/debris is removed from the air filter housing in order to prevent a repeat incident. Remember, only use a vacuum to remove dust/dirt/debris - do not blow compressed shop air inside the air filter housing.

2. Install a new genuine Nissan replacement air filter element into the filter housing cover, then install this assembly in the air filter housing.





3. Install the new complete airflow meter assembly (see Figure 1). Refer to the Parts Information table for the new airflow meter assembly part number.

IMPORTANT:
^ The new airflow meter assembly MUST be installed as a complete unit

^ Do not attempt to transfer the new airflow sensing element to the old airflow meter housing. The new element is not compatible to operate in the old housing and will cause performance and emissions to be impaired.

4. Determine the vehicle's Emissions Certification (California or Federal):

A. All 2001 I30 vehicles have California emissions certification

B. For 2000 I30 vehicles, you need to determine if the vehicle is certified for California or Federal emissions.





^ Check the Emissions Certification Label on the underside of the engine hood to verify if the certificate is for California emissions (see Figure 2).

^ If there is no mention of California on the label, the vehicle is certified for Federal emissions.





5. Determine the vehicle's ECM Part Number. The ECM P/N is found on top of the CONSULT-II self-diagnosis printout (see Figure 3), or by CONSULT ECM P/N Selection.

6. Compare the vehicle's ECM P/N to those shown under Current ECM P/N and New ECM Data P/N in Chart A.

A. If the ECM P/N in the vehicle does not match one of those listed in Chart A, Current ECM P/N column, do not perform ECM reprogramming.

B. If the ECM P/N in the vehicle does match one of those listed in Chart A, Current ECM P/N column:

^ Make a note of the new ECM data P/N and ECM ID Code

^ Reprogram the ECM. Refer to Attachment 1 as shown in this bulletin.

IMPORTANT NOTES:
^ This is a special ECM reprogram process and this procedure is used FOR THIS INCIDENT ONLY!





^ An ECM ID CODE must be entered (see Figure 4) to get the Reprogramming data from ASIST. This is different from the typical ECM Reprogramming procedures now in use, which requires the model and model year to be entered to look up ECM data in ASIST.

^ Attachment 1 - "Special ECM Reprogramming Procedure for ECM I.D. Entry" is to be used for this bulletin and is different from Attachment A which was released in previous bulletins. Do NOT use Attachment A for this bulletin.

The following provides steps to obtain the ECM reprogramming data from ASIST. For a detailed ECM reprogramming procedure, refer to Attachment 1 shown in this bulletin.

A. Click on the Keypad button (Refer to Figure 4).





B. Using the digit keys on the Keypad (see Figure 5), enter the correct ECM ID Code from Chart A.

C. Then click the "Continue" button on the keypad.





D. Click the "Continue" button on the ECM Data Reprogramming screen (see Figure 6) to proceed to CONSULT-II setup.
