Reprogramming the Unified Meter and A/C Amp
IMPORTANT:
•

Before starting, make sure your ASIST has been freshly synchronized and all C-III plus upgrades
have been installed. The Unified Meter and A/C Amp reprogramming software is delivered via ASIST
synchronization.

•

This reprogramming process requires an Internet connection. Make sure the CONSULT PC has an
Internet connection before starting.

•

The CONSULT PC must have the ability to print the calibration report while cable-connected to the
vehicle.

•

The software will not allow reprogramming of vehicles that are not affected by this campaign.

•

The reprogramming can only be applied one time to each affected vehicle. Vehicle identification is
validated against data located on NNA’s servers before reprogramming is allowed.

1. Use the USB cable to connect the plus Vehicle Interface (plus VI) to the CONSULT PC, and then connect
the plus VI to the vehicle.
2. Connect the AC Adapter to the CONSULT PC.
3. Make sure the CONSULT PC is connected to the PC Converter Box (J-50419-1) with the USB cable.
4. Turn the Ignition ON.
Odometer screen blank
NOTE:
With the ignition ON, the odometer screen should
be blank.
If the odometer screen is not blank:
a. Turn the ignition OFF.
b. Turn the CONSULT PC OFF.
Figure 1a
c. Disconnect and reconnect all of the reprogramming cables (see Figure 22 on page 11). Make sure
all connectors are securely connected.
d. Make sure the USB cables and A/C power supply are securely connected to the CONSULT PC.
e. Make sure the plus VI is securely connected to the vehicle.
f.

Go back and restart with Step 1 above.

CLAIMS INFORMATION
Submit a Campaign (CM) line claim using the following claims coding:
“CM” I.D.: P0303*
DESCRIPTION
Reprogram Unified Meter and A/C Amp

OP CODE
P03030

FRT
1.0

* Be sure that you input the updated mileage in Infiniti Net on the claim prior to the claim being
placed into “Invoice” status. Failure to do so may cause subsequent claims to suspend.
NOTE: Refer to Warranty Bulletin IWBI/10-023 for instructions on how to update the mileage in Infiniti Net.
The mileage on this claim should reflect the correct and updated mileage after
reprogramming is complete. This is being done to ensure the NEW CORRECT
mileage is on the campaign claim to reduce further suspensions.
If additional repairs are to be submitted as Factory Warranty (FW) or Service
Contract (SC), they must be claimed on a separate repair order with calibrated
mileage. Although, additional campaign claims may be submitted on the same
repair order.

OWNER’S LETTER (example of typical owner’s letter)
Dear Infiniti FX Owner:
Infiniti is committed to providing the highest levels of product safety, quality and customer satisfaction. We
believe our success depends on providing you with an exceptional ownership experience. With that in mind,
we want to bring to your attention important information about the speedometer and odometer in your 2007
Infiniti FX.
REASON FOR CAMPAIGN
Infiniti has identified a programming error in an electronic module that is part of the speedometer and odometer
in your Infiniti FX. The programming error will cause the speedometer display to indicate a speed that is 3.58%
higher than it would if the module had been properly programmed. The programming error also causes the
odometer to accrue miles 3.58% faster than it would if the module had been properly programmed.
WHAT INFINITI IS DOING
To assure your continued satisfaction and confidence in your FX, Infiniti will reprogram the electronic module on
all affected vehicles and reset the odometer to adjust the mileage to the mileage it would have displayed had it
not been for the programming error.
In addition to correcting the programming error, Infiniti will stand behind its customers to ensure they are not
disadvantaged by this error. Infiniti will provide reimbursement of documented costs incurred for any repairs
that should have been covered under warranty or for excess mileage charges on lease vehicle returns. If you
have already sold your vehicle, Infiniti will reimburse you for any documented loss of resale value due to the
higher odometer reading.
WHAT YOU SHOULD DO
Contact your Infiniti retailer at your earliest convenience in order to arrange an appointment. This service, free
for parts and labor, should take about two hours to complete, but your Infiniti retailer may require your vehicle
for a longer period of time based upon the workshop schedule. To ensure the least inconvenience for you, it
is important that you have an appointment before bringing your vehicle to the Infiniti retailer for
service. Please bring this notice with you when you keep your service appointment. Instructions have been
sent to your Infiniti retailer.
In the meantime, because the speedometer displays a speed that is higher (3.58%) than it should, you should
continue to rely upon the displayed speed as correct and do not attempt to compensate in any manner for the
programming error referenced above.
In addition, please contact Infiniti Consumer Affairs at 1-800-662-6200 for instructions on possible
reimbursement for related charges if you fall into one of the below categories:
1. You paid for repairs that would otherwise have been covered by the New Vehicle Limited Warranty, but
your vehicle’s mileage exceeded the mileage limit under the warranty by less than 3.58%.
2. You have returned a lease vehicle and paid an amount for excess mileage charges.
3. You sold your Infiniti FX and believe the resale value may have been impacted by the higher odometer
reading.
If you have additional questions you may contact the National Consumer Affairs Department, Infiniti Division,
Nissan North America, Inc., P.O. Box 685003, Franklin, TN 37068-5003. The toll free number is 1-800-6626200.
Thank you for your cooperation. We are indeed sorry for any inconvenience this may cause you.
