Service Procedure
Figure 1:
1. Print out the CONSULT-II Self-Diagnosis results.
- This print out will be used to check the ECM Part Number (determine if this bulletin applies).
- See Figure 1 for an example of the CONSULT-II Self-Diagnosis printout.
2. Compare the vehicle's current ECM P/N (from your CONSULT-II Self Diagnosis printout) to those shown under Current ECM P/N in Chart A-1 and A-2 below.
Chart A-1 (vehicles with a standard airflow meter.)
Chart A-2 (Vehicles with an updated airflow meter.)
A. If the ECM P/N in the vehicle does not match one of those listed under "Current ECM P/N" in Chart A-1 or A-2 above:
- This bulletin does not apply.
- Use the appropriate Electronic Service Manual (ESM) to further diagnose and repair the incident.
B. If the ECM P/N in the vehicle matches one of those listed under "Current ECM P/N" in Chart A-1 or A-2 above:
- Proceed with this Service Procedure.
3. Replace both rear oxygen sensors-HO2S2 B1 and B2.
- Refer to Figures 2 and 3 for HO2S2 location information.
Figure 2:
Figure 3:
4. Perform ECM reprogramming to install the latest available ECM data.
A. For vehicles with an ECM P/N that matches one listed in Chart A-1 (vehicles with a standard airflow meter):
- Perform standard ECM reprogramming.
- If you are unfamiliar with ECM Reprogramming, link to the "ECM Reprogramming For Infiniti Vehicles" general procedure or refer to Attachment A in the print copy of this bulletin.
B. For vehicles with an ECM P/N that matches one listed in Chart A-2 (vehicles with an updated airflow meter):
- Perform Special ECM reprogramming using the ECM ID Code.
- If you are unfamiliar with special ECM Reprogramming, link to the "SPECIAL ECM REPROGRAMMING PROCEDURE FOR ECM I.D. ENTRY "general procedure or refer to Attachment 1 in the print copy of this bulletin.
- This I.D. code reprogramming process is different from the standard ECM reprogramming procedures you may be used to.
IMPORTANT:
- Some vehicles may have an updated airflow meter with matching ECM reprogramming data
- To make sure you obtain the correct reprogramming data, the type of airflow meter installed in the vehicle should be confirmed by checking the ECM and airflow meter part numbers (P/N).
- Vehicles with an ECM P/N that matches one listed in Chart A-1 should have the standard airflow meter.
a. 2000 - 2001: Standard Airflow Meter P/N 22680-AD200
b. 2002: Standard Airflow Meter P/N 22680-6N201
- Vehicles with an ECM P/N that matches one listed in Chart A-2 should have the updated airflow meter.
a. 2000 - 2001: Updated Airflow Meter P/N 22680-2Y001
b. 2002: Updated Airflow Meter P/N 22680-AM600
Standard ECM Reprogramming
- For those familiar with standard ECM Reprogramming, perform the following:
Figure 4:
A. Select model and model year for the applied vehicle (example: I35, 2002).
B. Select the vehicle "configuration" from those listed in the upper right ECM data description window.
- For vehicle configuration, see Chart A-1
- Vehicle configuration example: 2002 with A/T.
C. Make a note of the "To" number listed in the "ECM Reprogramming Data" Summary screen.
NOTE: The "To" number will read: 23710-XXXXX.
D. Press "Continue" and follow directions to perform data download from ASIST to CONSULT-II.
E. When reprogramming from CONSULT-II, select the "To" number that you made note of in step C, above.
Special ECM Reprogramming Using an ID Code:
- Use these steps if you are familiar with this Special ECM reprogramming procedure.
- If you are unfamiliar with this Special ECM Reprogramming Procedure, refer to Attachment 1 in the printed copy of this bulletin.
1. Click on the Keypad button (see Figure 5).
Figure 5:
2. Use the digit keys on the KeyPad (see Figure 6 below), to enter the correct ECM ID Code from Chart A-2.
Figure 6:
3. Then click the "Continue" button on the keypad.
4. Click the "Continue" button on the ECM Data Reprogramming screen (see Figure 7) to proceed to CONSULT-II setup.
Figure 7:
5. Continue the reprogramming procedure as per SPECIAL ECM REPROGRAMMING PROCEDURE FOR ECM I.D. ENTRY; Attachment 1.
