2010 MAXIMA, MURANO, & V-6 ALTIMA; MIL IS ON
AND / OR SLOWER-THAN-NORMAL ACCELERATION
This bulletin has been amended to update the SERVICE PROCEDURE to CONSULT-III plus.
The REPAIR FLOW CHART and TCM P/N table have been amended.
Please discard all previous versions of this bulletin.
APPLIED VEHICLES: 2010 Maxima (A35)
2010 Murano (Z51)
2010 Altima Sedan (L32) equipped with VQ35DE engine ONLY
2010 Altima Coupe (CL32) equipped with VQ35DE engine ONLY
IF YOU CONFIRM:
The vehicle has slower-than-normal acceleration from a stop at times
and / or
The customer describes the vehicle has slower-than-normal acceleration from a stop at
times
NOTE: The condition of slower-than-normal accelerating from a stop, if it should
occur, happens more commonly when the vehicle has been driven for extended
periods at highway speeds.
and / or
The MIL is ON with DTC P1778 (STEP MOTOR) stored in Engine and/or Transmission.
ACTION:
Refer to the REPAIR FLOW CHART on page 2 for repair procedure.
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 REPAIR FLOW CHART (on page 2) and
the SERVICE PROCEDURE if applicable (starting on page 3) as they contain information
that is essential to successfully completing the 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.

REPAIR FLOW CHART
Intermittently, the vehicle:
a. Is slower than normal when accelerating from a stop
and / or
b. The MIL is ON and DTC P1778 (STEP MOTOR) is stored
in ENGINE and / or TRANSMISSION.
Perform appropriate
ESM diagnosis.
If Diagnosis Result leads to “Replace
Primary Speed Sensor”, “Secondary
Speed Sensor”, or “TCM”, instead,
replace the Control Valve Assembly
(Valve Body). DO NOT replace either
Speed Sensor, TCM, or Transaxle
Assembly.
Refer to the SERVICE PROCEDURE
on the next page.
V-6 Altima: Perform TCM Initialization
(Erase EEPROM) only.
Once complete, verify repairs.
NOTE: V-6 Altima does not need
TCM reprogramming.
Maxima and Murano: Reprogram the
TCM (as it applies) and perform TCM
Initialization (Erase EEPROM).
Once complete, verify repairs.
Work Completed.

SERVICE PROCEDURE
Remove Control Valve Assembly
PRECAUTIONS WHEN REPLACING CONTROL VALVE ASSEMBLY
Transmissions are vulnerable to particles (dust, metal, lint, etc.)
• When replacing a valve body, make sure your work environment (shop,
workbench, etc.), the transmission area (sub-frame, oil pan, harness connector,
etc.), and your hands are free of contamination.
• Make sure all parts are clean prior to installing on the vehicle. Unpack Service
Parts just before installation.
NOTE: The transmission does not need to be removed for this procedure.
1. Write down all radio station presets.

TCM Reprogramming: Determine and Perform if Needed
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) Reprogramming" general procedure.
CAUTION:
•
Connect the GR8 to the vehicle 12 volt battery and set to ECM power supply
mode. If the vehicle battery voltage drops below 12.0V or rises above 15.5V
during reprogramming, the TCM may be damaged.
•
Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the TCM 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 TCM 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 TCM may be damaged.

7. Follow the on-screen instructions to navigate C-III plus and reprogram the TCM.
NOTE:
•
In some cases, more than one new P/N for reprogramming is available.
¾ In this case, the screen in Figure 15 displays.
¾ 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.
IMPORTANT: If C-III plus locks up or freezes at this point or displays “cannot
complete reprogramming, the CONSULT PC is set up with User Rights.
Reprogramming can be completed with Administrator log in”, the TOUGHBOOK
settings need to be changed so that Users have full access rights. See your
Dealership’s IT System Administrator for details.

TCM Initialization Procedure
NOTE: If reprogramming is not performed, make sure TCM initialization is performed as
part of the control valve assembly replacement.
1. Set the parking brake with the selector lever in “P” (Park).
2. Attach C-III plus to the vehicle with the plus VI.
3. Turn the ignition ON (engine OFF - not running).
4. Open C-III plus and navigate screens to: Diagnosis One System >> Transmission >>
Calibration Data.
5. Print the Calibration Data and save a copy (or write down the calibration data).
6. Select Transmission Self Diagnostic Results.
7. Perform the initialization (EEPROM erase) procedure as follows:
a. Press and hold the brake pedal.
b. Shift the selector lever to “R” (Reverse).
c. Press and hold the accelerator pedal down about one-third, but no more than
halfway.
• The purpose of this step is to get both the wide open throttle and closed throttle
position signals to read “OFF” at the same time.
d. Press Erase on the C-III plus screen.
e. Shift the selector lever to “P” (Park).
NOTE: If the EEPROM erase was successful, the “P” in the instrument display will
have a short delay (about 1.5 seconds) before illuminating after shifting to park.
f. Remove foot from brake and accelerator.
g. Turn the ignition OFF.
h. Wait 5 seconds.
i. Turn the ignition ON.
8. On C-III plus, select Transmission Calibration Data again.
9. Print the Calibration Data and save a copy (or write down the calibration data).
10. Compare the values between the first and second Calibration Data prints.
•
The procedure is complete if the values are different.
•
If the values are not different, repeat the procedure.
11. Make sure to erase DTCs from all systems.
12. Return to page 10, step 31.
