Engine Controls - PCM Reprogramming ProcedureNo: TSB-03-00-015 DATE: September, 2003MODEL: All modelsSUBJECT:REPROGRAMMING WITH THE MUT-III

PURPOSE

This bulletin contains general instructions for reprogramming a vehicle PCM using the MUT-Ill vehicle communication interface (VCI) unit. Before beginning reprogramming, you must first transfer the reprogramming data to a PC memory card adapter equipped with a compact flash memory chip. New data is transferred from a DVD to the PC hard drive, then to the PC memory card. After data is in the memory card, it can be downloaded to the VCI, then to the vehicle's PCM (ECU).

The MUT-III is capable of both automatic reprogramming (it automatically selects the appropriate database) and manual reprogramming (you select the database). Automatic reprogramming is recommended for most typical reprogramming situations. If automatic reprogramming is not successful, try manual reprogramming.

AFFECTED VEHICLES

All models capable of PCM reprogramming, except 1995-99 Eclipse 2.0L non-turbo (For 1995-99 Eclipse 2.0L non-turbo models, use M1T992000-A and refer to the applicable TSB.)

I. Transferring Reprogramming Data to Memory Card

Before beginning reprogramming, you must first transfer new reprogramming data from a DVD to a PC memory card adapter equipped with a compact flash memory chip. The data is transferred from the DVD-ROM to the PC hard drive, then to the PC memory card.

Components

MUT-III personal computerReprogramming database on DVD-ROMMemory card (MB991853)128 MByte Compact Flash (CF) *Memory card adapter (MB991939) PCMCIA ** Replacement generic memory and adapters can be ordered from SPX/OTC, or

purchased locally.

Procedure

1. Start the MUT-III personal computer.2. Start the MUT-III system.

3. Install the memory card into the card adaptor.4. Install the card adapter into the PC card slot. (There are two PC card slots. You can

use either slot for the card adapter.)

A "Found New Hardware" message displays on the monitor. Wait for the message to disappear.

5. When you receive new reprogramming data, install the reprogramming DVD-ROM into the PC's DVD-ROM drive.

6. Select "Special function".7. Select "ECU reprogramming".8. If a "Please update to a new database file" message displays, press the check mark

button.9. A "Please wait!" message displays. When the transfer is complete, the message

disappears. Then remove the DVD-ROM from the PC.10. Select "Memory card transfer". (Do not remove the memory card from the PC.)11. Select memory card "E:\" and press the check mark button.12. When the message "It transfers data to the memory card. Are you ready?" displays,

press the check mark button.13. A progress monitor displays during data transfer to the memory card.14. When the message "Transfer is complete" appears, press the check mark button.

To remove the memory card:

15. Double-click the removal icon in the lower right corner of the screen.16. Select "PCMCIA IDE/ATAPI Controller" . Then press the Stop button.17. Verify that the correct item is selected, then press the OK button.

When the message "The device can now be safely removed from the system" displays, remove the memory card (press the button next to the PC card slot).

II. Reprogramming A Vehicle ECU With the Vci

After data is in the memory card, it can be downloaded to the VCI, then to the vehicles PCM (ECU). NOTE : Whenever the ECU is reprogrammed, a reprogramming label (p/n MSSF-024G-00) must be completed and affixed to the vehicle. Refer to the applicable reprogramming TSB for specific information that must be entered on the label.

VCI COMPONENTS

These components are required:

CONNECTING COMPONENTS

1. Insert the memory card into the PC card adapter. Then install into the VCI main unit.2. Connect the MUT-III main harness A or B to the VCI main unit.3. With the ignition switch in the OFF position, connect the MUT-III main harness to the

data link connector.NOTE :For Outlander and 2002-on Montero models, use 12-pin to 13-pin adapter harness MB991855 to connect the main harness to the data link connector.

4. Turn the ignition switch to the ON position.

MAIN MENU

Turn the ignition key to ON. When the VCI unit is turned on, the main menu displays:

IMPORTANT

^ When connecting and disconnecting, do not pull on the harness wires. Pull only on the connectors.

^ During reprogramming, the ignition switch must remain ON.^ Do not disturb the MUT-III main harness during reprogramming. After reprogramming,

start the engine to verify operation.

Automatic reprogramming is recommended for most typical reprogramming situations. If automatic reprogramming is not successful, try manual reprogramming.

AUTOMATIC REPROGRAMMING

1. In the VCI main menu. select "Automatic RPG". Then press ENTER.

The available data will display.

2. Press ENTER. If the PCM requires reprogramming, the MUT-Ill will automatically identify the appropriate database. Press ENTER again to transfer the reprogramming data to the VCI.

a. If the PCM does NOT require reprogramming, this message displays. Press ENTER to return to the main menu.

b. If there is no data for reprogramming this PCM, this message displays and no data is transferred. Press ENTER to return to the main menu.

3. A progress monitor displays during data transfer to the VCI internal memory.

4. When data transfer is complete, ECU reprogramming automatically begins.

5. The ECU part number and ROM ID are displayed. Press ENTER to continue with reprogramming.

6. If the database you selected does not apply to the vehicle's PCM, this message will display. Press ENTER to return to the VCI main menu. Confirm PCM part number and appropriate reprogramming database number.

7. If the PCM has already been reprogrammed with this database, or if the MUT-III main harness is not properly connected to the VCI unit, this message displays and reprogramming will not continue.

8. Verify that the harness is connected properly, then press ENTER. The VCI will retry reprogramming.

9. A monitor indicates that reprogramming is in progress.

There are five phases in the reprogramming process. The VCI will continue with the process automatically. Do not press any key.

Step 1: Saves data to the back-up memory.

Step 2: Erases data in the ECU.

Step 3: Writes new data in the ECU.

Step 4: Verifies the new data is transferred.

Step 5: Erases diagnosis and back-up memory.

10. The new ECU part number and ROM-ID display.

You must turn the ignition switch to OFF to complete the reprogramming process.

11. Start the engine and disconnect the MUT-III.

MANUAL REPROGRAMMING

1. In the main menu, select "Load RPG file". Then press ENTER.

2. Select the reprogramming database by using the down arrow. Then press ENTER.

3. If the correct database is selected, press ENTER. If not, press ESC to cancel and return to the main menu.

4. A progress monitor displays during data transfer to the PC memory card.

5. After the data has been transferred to the PC memory card, this message displays.

6. The ECU part number and ROM ID are displayed. Press ENTER to continue with reprogramming.

7. If the database you selected does not apply to the vehicle's PCM, this message will display.

Press ENTER to return to the VCI main menu. Confirm PCM part number and appropriate reprogramming database number.

8. If the PCM has already been reprogrammed with this database, this message displays and reprogramming will not continue.

It is possible that the MUT-III main harness is not properly connected to the VCI unit.

9. Verify that the harness is connected properly, then press ENTER. The VCI will retry reprogramming.

10. A monitor indicates that reprogramming is in progress.

There are five phases in the reprogramming process. The VCI will continue with the process automatically. Do not press any key.

Step 1: Saves data to the back-up memory.Step 2: Erases data in the ECU.Step 3: Writes new data in the ECU.Step 4: Verifies the new data is transferred.Step 5: Erases diagnosis and back-up memory.

11. The new ECU part number and ROM-ID display.

You must turn the ignition switch to OFF to complete the reprogramming process.

12. Start the engine and disconnect the MUT-III.
