APPLIED VEHICLE:
2003 Murano (Z50)
IF YOU CONFIRM
You need to replace the CVI assembly for any reason.
ACTIONS
Reprogram the TOM. This must be done to ensure the vehicle has the latest program.
IMPORTANT:
Make sure to erase the TCM EEPROM Memory as part of the Reprogramming.
IMPORTANT:
The purpose of "ACTIONS" (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.
CLAIMS INFORMATION
Submit a Primary Failed Part (PP) line claim using the claims coding shown.
SERVICE PROCEDURE
Vehicle TCM Reprogramming Overview
^ There are five basic steps:
1. Download (transfer) reprogramming data from ASIST into CONSULT-II.
2. "Preparation" steps before reprogramming TOM.
3. Erase the TCM EEPROM memory.
4. Reprogram the TCM.
5. "Wrap-up" after reprogramming is finished.
Step One: Download (Transfer) Reprogramming Data From ASIST Into CONSULT-II
^ For those familiar with TCM Reprogramming, please review the following steps and use them as a Quick Reference for TOM reprogramming.
1. Select vehicle model and model year (example: Murano, 2003).
2. Select the correct reprogramming data:
a. Locate the specific "Model Configuration" (example: VQ35, CVI, 2WD).
NOTE:
Model Configuration may include items such as engine type, transmission type, and vehicle options such as ASCD, TCS, ABS etc.
b. Select (click on) the "To" number.
NOTE:
The "To" number will read: 31036-XXXXX.
3. Click on the "Add" button.
^ This will add the data you selected to the "File(s) Selected" list.
4. Write the "To" number on the Repair Order.
5. Click on "Continue" and follow directions to perform "data transfer" (download) from ASIST into CONSULT-II.
Step Two: Preparation Steps Before Reprogramming TCM
1. Connect a battery charger to the vehicle's battery.
Set the charger to a low charge rate (trickle charge).
CAUTION:
For number 2 and number 3, DO NOT connect the CONSULT-II A/C Power Supply.
2. Press [SUB MODE] (see Figure C) then:
a. From the listed items, find and select [BATTERY CHARGE].
3. Check the CONSULT-II's "Charger Input" reading (see Figure D).
NOTE:
^ "Battery Voltage" is the voltage level of CONSULT-II's battery.
^ "Charger Input" is the voltage level of the vehicle's battery. (It must be above 12 volts.)
CAUTION:
If the "Charger Input" is below 12 volts:
^ A list of items to check when "Charger Input" voltage is below 12V is contained in the "TCM Reprogramming For Nissan Vehicles" general procedure.
Step Three: Erase the TCM EEPROM Memory.
1. Connect CONSULT-II to vehicle's Data Link Connector.
2. Turn ignition switch ON. Confirm that CONSULT-II is turned ON.
3. Move transmission gear selector lever to "R" position.
4. Touch START on CONSULT-II.
5. On CONSULT-II select TRANSMISSION > SELF-DIAG RESULTS.
6. Press on the Brake Pedal (Brake switch ON).
7. Press and hold the accelerator pedal down about one-third, but no more than halfway. (The need here is to hold the throttle open just enough so the closed throttle position signal is OFF and the wide open throttle position signal is also OFF.)
8. On CONSULT-II touch ERASE, then touch YES.
9. Wait 3 seconds and then release the accelerator pedal.
10. Turn ignition switch OFF.
Step Four: Reprogram the TCM
^ If you are not familiar with TCM Reprogramming:
^ This will link you back to a general procedure called "TCM Reprogramming For Nissan Vehicles."
Step Five: TCM Reprogramming "Wrap-up"
1. Turn the ignition and CONSULT-II OFF.
2. Disconnect CONSULT-II from the vehicle.
3. Start the Engine and make sure the MIL is OFF.
^ If it's still ON, use CONSULT-II with the Diagnostic (red/white) Card to erase any DTC's that may have stored in the TCM and/or the ECM during the reprogramming procedure.
4. Confirm there are no leaks from the transmission. Test-drive the vehicle and make sure the transmission operates correctly in all modes and has a normal power level when starting from a stop.
^ See the AT section of the appropriate Service Manual for operation specifications.
