Procedure
PROCEDURE1. Replace the Torque Converter. Refer to section 23 of the applicable service manual for details.
2. Check the underside of the hood to verify that there is no label previously installed to indicate that this TSB reprogramming has already been done. If no label is present reprogram the PCM using the following instructions.
3. The following equipment is needed to reprogram the PCM for this concern:
^ MEDIC II at version 4.0A or higher.
^ MUT-III STV 17.0/RAIDER STV at version 3.5 or higher.
^ VCI (Vehicle Communication Interface) - MB991824
^ MUT-III main harness A (blue) - MB991910
^ USB 2.0 cable - MB991827
^ "Engine Compartment/Control Module" labels - p/n MSSF-024G-00
4. Check that the MEDIC II of the MUT III software is to the appropriate level to successfully complete reprogramming,
For MEDIC II users ONLY:
1. Verify that the MEDIC II is at download M159 or higher.
a. If your MEDIC II Down-load is below M159 update your MEDIC II as follows.
2. On the MEDIC-II main screen click on "Maintenance".
3. Click on "Download". After the download completes click on "Cancel" to exit the "Maintenance" window.
GO TO REPROGRAMMING PROCEDURE.
For Stand-alone MUT III users only:
If you have a stand alone Scan Tool (MUT-III), determine the version of the software and if necessary, install the MUT-III STV 17.0/ RAIDER STV 3.5 Upgrade CD to your MUT-III laptop.
1. Check the Raider STV version number:
a. I your Raider STV is version 3.5 or greater, go to the REPROGRAMMING PROCEDURE.
b. If your Raider STV version is below 3.5, go to Step 2 to update your database.
2. Install MUT-III STV 17.0/RAIDER STV 3.5 Upgrade CD to your MUT-III laptop as follows:
a. With the MUT-III laptop on close the Raider STV and MUT-III STV.
b. Install the MUT-III STV 17.0/RAIDER STV 3.5 Upgrade CD into the laptop.
C. Follow the instructions displayed on-screen for loading the database onto your laptop.
REPROGRAMMING PROCEDURE
BATTERY VOLTAGE MUST BE MAINTAINED BETWEEN 13.2 AND 13.5 VOLTS. USE A VOLTMETER TO CHECK THE CONDITION OF THE BATTERY. CHARGE THE BATTERY AS NECESSARY. CONNECT A BATTERY CHARGER ON A CONTINUOUS CHARGE DURING THE PROCESS. DO NOT ALLOW THE BATTERY CHARGER TO TIME OUT. DO NOT ALLOW CHARGING VOLTAGE TO EXCEED 13.5 VOLTS DURING THE PROCESS.
1. Connect the equipment as follows:
a. Start the laptop computer.
b. Connect the USB cable to the VCI.
c. When the laptop displays the MUT-III main screen connect the USB cable to the laptop.
d. Connect the blue MUT-III main harness to the VCI.
e. Connect the other end of the blue MUT-III main harness to the vehicle's data link connector.
f. Turn the VCI power switch ON. Verify that the indicator lamp in the upper right corner of the screen is green.
NOTE:
If the USB cable is disconnected during this procedure, a warning message will display. Close the message display by clicking on the OK button.
2. Refer to the attachment shown in this bulletin or the "Raider ECU Part Number & ECU Calibration" chart on the Mitsubishi Dealer Link in the Service Tech Resources page to identify the appropriate calibration for this programming.
