2014 – 2015 TAXI; MIL ON WITH DTC P0101

APPLIED VEHICLE:

2014 – 2015 Taxi

IF YOU CONFIRM
The MIL is ON and DTC P0101 (MAF SEN/CIRCUIT-B1) is stored.

ACTION
1. Replace the PCV valve with the new one listed in the Parts Information.

2. If needed, reprogram the ECM.


Refer to step 6 in the ECM Reprogram section of the SERVICE PROCEDURE to
confirm if reprogramming is needed.

IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you
will be performing. You MUST closely follow the entire SERVICE PROCEDURE as it
contains information that is essential to successfully completing this repair.
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.

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.

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.



If there is not a match, reprogramming is not needed.

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.
