Reprogramming the Unified Meter and A/C Amp
Reprogramming the Unified Meter and A/C AmpIMPORTANT:
^ Before starting make sure your ASIST has been freshly synchronized and all C-III 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 C-III computer has an Internet connection before starting.
^ The C-III computer 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.
NOTE:
Make sure the C-III computer is turned OFF.
1. Use the USB cable to connect the Vehicle Interface (VI) to the C-III computer and then connect the VI to the vehicle.
2. Connect the AC Adapter to the C-III computer.
3. Make sure the C-III computer is connected to the PC Converter Box (J-50419-1) with the USB cable.
4. Turn the Ignition ON.
NOTE
With the ignition ON the odometer screen should be blank.
If the odometer screen is not blank:
a. Turn the ignition OFF
b. Make sure the C-III computer is OFF.
c. Disconnect and reconnect all of the reprogramming cables (See figure 22). Make sure all connectors are securely connected.
d. Make sure the USB cables and A/C power supply are securely connected to the C-III computer.
e. Make sure the VI is securely connected to the vehicle.
f. Go back and restart with Step 1 above.
5. Turn ON the C-III computer (do not launch / start C-III at this time).
^ The first time the reprogramming kit (PC converter box) is attached to either of the C-III USB ports the following screens (Figures 1b - 1d) will display.
^ If this is not the first time these screens will not display - go to step 6.
NOTE:

10. Wait for the "Detecting VI/MI" in progress message to clear.
11. Select the "Detected VI" from the list.
12. Select Connect.
13. Wait for the Checking the firmware version message to clear.
14. Wait for a few seconds while the reprogramming software obtains the VIN.
15. The FX Odometer Calibration Tool will launch automatically (see Figure 1i above).
16. Look at the "busy" lights on the converter box (see Figure 1h).
^ If both busy lights are not flashing go to Step 17.
^ If either busy light is flashing:
a. Select Repair Firmware (see Figure 1i).
b. Follow the on screen instructions for Firmware Repair.
c. Close the Odometer Calibration Tool - click on the X in the upper right corner of the window (see Figure 1i).

If an error message is displayed and one or both of the busy lights on the converter box are flashing:
a. Close the error message.
^ The display window will return the Odometer Calibration Tool (see Figure 1i).
b. Select Repair Firmware (see Figure 1i).
c. Follow the on screen instructions for Firmware Repair.
d. Close the Odometer Calibration Tool - click on the X in the upper right corner of the window (see Figure 1i).
e. Go backto Step 7.
If the calibration fails to complete and the busy lights on the converter box are not flashing:
a. Make sure the Internet connection is working.
b. Turn the ignition OFF.
c. Turn the C-III computer OFF.
d. Disconnect and reconnect all of the reprogramming cables (see Figure 22). Make sure all connectors are securely connected.
e. Make sure USB cable and A/C power supply are securely connected to the C-III computer.
f. Go back to (Reprogramming the Unified Meter and A/C Amp) and restart with Step 1.
21. When the calibration process has completed successfully the message in Figure 1k will display.
22. Turn the ignition OFF and select Continue.
