Repair Procedure
REPAIR PROCEDURENOTE:
Reprogramming the ECM with the latest database (i.e. N11051) includes all past and current reprogramming for TSBs to this or any earlier database numbers. You do not need to reprogram the ECM for each TSB.
1. Check the underside of the hood to verify there is no "Authorized Modification" (See warranty information for example) previously installed to indicate this reprogramming has already been completed. If a label is present and the "ROM ID #" on the label matches the "New S/W Part No." in the table shown in the beginning of this bulletin, the ECM is at the latest level and reprogramming is not necessary.
For MEDIC 3 users only: (MUT-III users go to step 4)
2. Verify your MEDIC 3 is at version 3.0 and at update 061 or higher.
If your MEDIC-3 update is at least 061, continue with the Reprogramming Procedure.
^ If your MEDIC-3 update is below 061, update your MEDIC 3 as follows.
3. Select the MEDIC 3 Admin tab and click on "Updates."
4. The MEDIC Updates screen appears. If you see "Updates Available" in the "Activity" panel, click the "Begin" button.
The "Activity" panel will advise when updates are complete.
5. GO TO THE REPROGRAMMING PROCEDURE.
6. Standalone MUT-III Scan Tool Viewer (STV) ONLY (MEDIC-II USERS go to the Reprogramming Procedure.
Verify that your MUT-III has the most current version of the reprogramming database:
a. From the MUT-III Main Page, confirm your MUT-III version is Ver 25.0.
1. If version 25.0 is displayed on your MUT-III, continue to the Reprogramming Procedure.
2. If the version displayed on your MUT-III Main Page is lower than version 25, locate the MUT-III Scan Tool Viewer CD (ver 25.0) and follow the instructions on the CD label to update your MUT-III.
REPROGRAMMING PROCEDURE
CONNECT A BATTERY CHARGER TO THE VEHICLE'S BATTERY DURING THE REPROGRAMMING PROCEDURE. DO NOT ALLOW THE BATTERY CHARGER TO TIME OUT. BATTERY VOLTAGE (AS MEASURED AT THE BATTERY POSTS WITHOUT ELECTRICAL LOAD) MUST BE KEPT AT 12.4V OR HIGHER IN ORDER TO REPROGRAM THE ECM. MEASURE THE BATTERY VOLTAGE AND CHARGE AS NECESSARY.
NOTE:
VCI Stand-alone reprogramming is not available for this procedure. The laptop and the VCI must remain connected for the entire procedure.
Connect the reprogramming equipment as follows:
^ Turn the laptop computer on. If you're running on battery power and the charge indicator in the lower right hand corner of the screen does not show a full charge it is recommended that either the laptop battery be charged prior to beginning or that reprogramming be completed with the A/C power adaptor connected to the laptop.
^ Connect the USB cable to the VCI.
^ When the laptop displays the MUT-III main screen connect the USB cable to the laptop.
^ Connect the MUT-III main harness with the blue DLC connection to the VCI.
^ Connect the blue connector of the MUT-III main harness to the vehicle's data link connector.
^ Turn the VCI power switch ON. Verify that the indicator lamp in the upper right corner of the screen is green.
CAUTION
DO NOT DISTURB THE HARNESS CABLES OR CONNECTIONS. INTERRUPTION DURING THE REPROGRAMMING PROCESS COULD CAUSE THE CONTROL UNIT TO LOSE DATA OR PREVENT FUTURE REPROGRAMMING. IF THE USB CABLE IS DISCONNECTED DURING THIS PROCEDURE, A WARNING MESSAGE WILL DISPLAY.
ECM Reprogramming
1. Conduct the following steps to reprogram the ECM.
a. Turn the ignition switch to the ON position. If the vehicle is equipped with the F.A.S.T. System the transmitter must remain in the vehicle for the entire procedure.
b. If using MEDIC-II from the main page, click the MUT-III STV icon at the top center of the screen.
c. Select "Special Function."
d. Select "ECU reprogramming."
e. Select "Automatic Reprogramming (CAN)."
f. Click on the car icon at the bottom of the page.
g. If the VIN or vehicle description displayed does not match the vehicle you are working on click on the eraser icon at the bottom of the page.
Select VIN by clicking on the VIN button.
h. Click on the icon in the lower RH corner of the screen to have MUT-III automatically read the VIN. If a message appears saying that the VIN cannot be input automatically manually type the 17 digit VIN into the VIN field at the top of the page.
Make sure the VIN is correct and click on the check mark.
I. Confirm that all data matches the vehicle and click the check mark at the bottom of the page.
j. MFI should be highlighted as the default. If not, click on it to highlight it.
Click on the check mark at the bottom of the page.
k. A message will advise that the system will 'Automatic search the data."
Click on the check mark to continue.
ECM TO LATEST VERSION
If an "Complete Reprogramming" message does not appear, continue with step I.
If this message is displayed, the ECM software is already at the most current level. Do not continue with this reprogramming procedure. This TSB does not apply.
Click the check mark to clear the window, then click on the Home icon at the lower left corner of the screen to return to the System Select main page.
Turn off the ignition switch and disconnect the MUT-III. Turn off and disconnect the battery charger. Conduct normal diagnosis.
I. The CAN database screen will display.
Confirm the database number at the top right of the table is N11051 or higher.
If more than one row is displayed in the table, refer to the ECM Reprogramming Chart to select the proper Data No. for this procedure and select the appropriate row.
Click on the correct row to highlight it. Click on the check mark to continue.
m. A message will ask you to "Check reprogramming data."
n. Click on the check mark to begin reprogramming.
It will take up to 5 minutes for reprogramming to complete.
CAUTION
The Daytime Running Lights and both the engine and condenser fans will automatically be turned on during reprogramming. Care should be taken to insure nothing gets caught in the moving blades. The radio will be turned off and you will also hear a chime in the interior for a short period of time. These are normal conditions.
0. This message will display when ECM reprogramming is successfully completed. Confirm the "New S/W P/N" displayed matches the table.
p. You will be prompted to turn the ignition switch to the OFF position, wait at least 8 seconds, then turn it back on.
q. Click the check mark and you will be returned to the "ECU Reprogramming" page.
