VOLUNTARY EMISSION SERVICE CAMPAIGN
2015 TAXI ECM REPROGRAM
PM652
CAMPAIGN ID #:
APPLIED VEHICLE: 2015 Taxi
Check Service COMM to confirm campaign eligibility.
INTRODUCTION
Nissan is conducting a Voluntary Emission Service Campaign on certain 2015 Taxi
vehicles to reprogram the Engine Control Module (ECM) for improper calibration. The
improper calibration may result in poor idle quality and/or a P0101 DTC and a Malfunction
Indicator Light (MIL) illumination. This service will be performed at no charge for parts or
labor.
IDENTIFICATION NUMBER
Nissan has assigned identification number PM652 to this campaign. This number must
appear on all communications and documentation of any nature dealing with this campaign.
DEALER RESPONSIBILITY
Dealers are to correct each vehicle falling within the range of this campaign that enters the
service department. This includes vehicles purchased from private parties or presented by
transient (tourist) owners and vehicles in a dealer’s inventory.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

SERVICE PROCEDURE
Reprogram the ECM
NOTE:

Most instructions for reprogramming with CONSULT-III plus (C-III plus) are
displayed on the CONSULT PC screen.

If you are not familiar with the reprogramming procedure, click here. This will link
you to the "CONSULT- III plus (C-III plus) ECM Reprogramming" general procedure.

Take the vehicle for a 10 minute drive in order to meet the following Idle Air Volume
Learn (IAVL) conditions:
 Engine coolant temperature: 70 -100°C
(158 - 212°F)
 Battery voltage: More than 12.9V (At idle)
 Transmission: Warmed up

After reprogramming is complete, you will be
required to perform Idle Air Volume Learn. The
above condition are required for Idle Air Volume
Learn to complete.

CAUTION:




Connect the GR8 to the 12V battery and select ECM Power Supply Mode.
If the vehicle battery voltage drops below 12.0V or above 15.5V during
reprogramming, the ECM may be damaged.
Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the ECM may be damaged.
Be sure to connect the AC Adapter.
If the CONSULT PC battery voltage drops during reprogramming, the
process will be interrupted and the ECM may be damaged.
Turn off all external Bluetooth® devices (e.g., cell phones, printers, etc.)
within range of the CONSULT PC and the VI. If Bluetooth® signal waves
are within range of the CONSULT PC during reprogramming,
reprogramming may be interrupted and the ECM may be damaged.

1. Connect the CONSULT PC to the vehicle to begin the reprogramming procedure.
2 Start C-III plus.
3. Wait for the plus VI to be recognized.

The serial number will display when the plus VI is recognized.
4. Select Re/programming, Configuration.

6. When you get to the screen shown in Figure 2, confirm this bulletin applies as follows.
A. Find the ECM Part Number and write it on the repair order.
NOTE: This is the current ECM Part Number (P/N).
6A: Current ECM P/N

B. Compare the P/N you wrote down to the numbers in the Current ECM Part Number
column in Table A.

If there is a match, continue with the reprogramming procedure; proceed
to step 7.

If there is not a match, reprogramming is not needed; proceed to Claims
Information for “Does Not Require Reprogram”.

7. Follow the on-screen instructions to navigate C-III plus and reprogram the ECM.
NOTE:

In some cases, more than one new P/N for reprogramming is available.
 In this case, the screen in Figure 3 displays.
 Select and use the reprogramming option that does not have the message
“Caution! Use ONLY with NTBXX-XXX”.

If you get this screen and it is blank (no reprogramming listed), it means there is no
reprogramming available for this vehicle. Close C-III plus and refer back to ASIST for
further diagnosis.
