ECM Reprogramming
ECM Reprogramming1. Conduct the following steps to reprogram the ECM.
a. Turn the ignition key or knob (F.A.S.T. equipped) to the ON position. If the vehicle is equipped with the F.A.S.T. System, the fob must remain in the vehicle for the entire procedure.
b. Select "Special Function."
c. Select "ECU reprogramming."
d. Select "Automatic Reprogramming (CAN)."
e. Click on the car icon at the bottom of the page.
f. If the VIN listed 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 button.
g. Click on the icon in the lower RH corner of the screen to have the 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.
Confirm that the VIN is correct and click on the check mark.
h. If it was not completed automatically, input the vehicle class. Click on the CLASS button, select the appropriate class from the menu and then click the check mark at the bottom of the page. Vehicle class can be found on the Vehicle Information Code Plate riveted to the base of the RH b-pillar (see photo above). The class is part of the model code.
Click the check mark to enter the class.
Confirm that all of the data is correctly entered and click the check mark at the bottom of the page.
i. MFI should already be highlighted. If not, click on it to highlight it.
Click on the check mark at the bottom of the page.
j. A message will advise you that the system will "Automatic search the data."
Click on the check mark to continue.
NOTE:
If a "Complete Reprogramming" message does not appear, continue with step k.
If a "Complete Reprogramming" message is displayed, the ECM is already reprogrammed for this concern. If this message displays, do not continue with this reprogramming procedure.
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.
k. The CAN database screen will display.
Confirm the database number at the top right of the table is N08051 or higher.
If more than one row is displayed in the table, select the appropriate ECM part number.
Click on the check mark to continue.
l. Click on the check mark to begin reprogramming.
NOTE:
The reprogramming procedure will take up to 5 minutes 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.
m. This message will display when the ECM reprogramming is successfully completed. Record the S/W (Software) Part No. and compare it to the "New Part No." in the table.
Click the check mark and you will be returned to the "ECU Reprogramming" page.
Click the "Home" icon at the bottom left side of the screen.
2. Turn the ignition key/knob to the OFF position, wait approximately 10 seconds, then turn it back on.
3. Using the MUT-III, check and erase ALL DTCs from all systems as follows.
a. Select "Special Function.
b. Select "All DTCS," then select "ERASE AND READ ALL DTCS."
This step erases all DTCs recorded in the ECM memory and then rechecks to confirm that they do not return.
c. Inspect the list on the left side of the screen and ensure that the selections checked match the options on the vehicle. DTCs may be set if the the options are incorrectly entered.
NOTE:
At this time, the check mark at the bottom of the page is not highlighted (active).
d. In the system list, scroll to and click on FAST/IMMOB/KEYLESS and check the correct option code (VF#) from the Loading Options Setup list.
Compare the selections with the vehicle's equipment to select the correct options. This will activate the check mark at the bottom of the page.
Click the check mark for DTC erasing and reading to begin.
4. If DTCs remain, diagnose and repair the condition as per the Service Manual. If no additional DTCs are listed, click the check mark to clear the window and then click the Home icon in the lower left of the screen to return to the main menu.
5. Using a ball-point pen, enter the appropriate Engine Control Module (ECM) part number, vendor number, Software Part Number, this technical service bulletin number (TSB-08-13-011), your dealer code, and the current date on the Engine Compartment / Control Module Label (p/n MSSF024G00). The label is available from your facing PDC.
The Control Module Label is NOT used for this reflash. It should be discarded.
6. Carefully remove all dirt and oil from a vacant area near the VECI label on the underside of the hood, and affix the Engine Compartment Label (LH side, above) to that area.
7. Disconnect the MUT-III and the battery charger.
