Part 3: How to use mut-3 VCI for Mitsubishi ecu reprogramming
Reprogramming with V.C.I. alone
(Not supported by V.C.I.-Lite)
Data Transfer (PC –> Memory Card)
Start up the M.U.T.-III system
Insert the Memory card (MB991853, MB992228) into the Card Adaptor (MB991939), and then insert them into m-card slot on PC.
Press Special Function button on STV Top Menu
Select System Function tab and press ECU reprogramming button
Caution:
-In case an update CD-ROM is set in the PC with update undone, data update starts
Press Memory card transfer button
ALL reprogramming data in the M.U.T.-III PC are transferred to the memory card.
Caution:
-Do not remove the memory card from PC.
Select a memory card drive to start transferring
It transfers data to the memory card. Are you ready?
Data transferring…
The progress bar is displayed during the transfer.
The data transfer is complete
Before you remove the memory card, double-click the below icon for removal of the adaptor.
Select [PCMCIA IDE/ATAPI Controller] or the other appropriate devices, then stop
Verify the contents of the selection, then OK
After displayed the message “The device can now be safely removed from the system”, push the lever on the side of PC card slot and remove the memory card.
Caution:
Do not remove the memory card away unless complete above method or turn off the PC.
Set up equipment
(1)Insert the Memory card (MB991853, MB992228), which is storing the reprogramming data, into the Card adaptor (MB991939) and insert them into V.C.I. main unit (MB991824)
(2)Connect M.U.T.-III Main Harness B (MB991911) or
A (MB991910) to V.C.I. main unit securely. (Refer to 10-2.) Note:
Select appropriate harness by instruction below.
-Main harness A: For vehicle only equipping 16 pin data-link-connector.
-Main harness B: For other vehicles.
-Adaptor harness (12-13): Outlander, Montero (after ‘02MY) (To connect Main harness B and 13pin data-link-connector)
(3)After verifying the ignition switch position at LOCK (OFF), connect the M.U.T.-III Main harness B or A to the data-link- connector.
(4)Turn Ignition switch on, and turn V.C.I. main switch on. (Do not start engine)
Retrieve Data (Memory card –> V.C.I.)
(a). Automatic Data Retrieval
(b). Select and Load Data
(c). (Special case)
Retrieve Automatic Data
(1)Select “Automatic RPG” in main menu and press Enter key. Version No. of data base file appears.
By waiting 10sec or pressing Enter key, V.C.I starts communicating with ECU and retrieves reprogramming data file with the ECU’s parts No. and ROM-ID.
（2）The appropriate reprogramming data file No. is displayed. Pressing Enter key starts transferring the data file into V.C.I
built-in-memory.
Remark:
?To search another data, press Esc key. If another appropriate reprogramming data exist, it will be displayed.
?The message bellows are displayed depends on ECU parts No, ROM-ID and condition of ECU. Press Enter Key to move back to Main menu.
“No update data in PC card”
This message appears if no pertinent reprogramming data exists. No data will be transferred.
“ECU at current level of VCI”
This message appears if the ECU has been already reprogrammed. No data will be transferred.
(3)Progress is displayed on the monitor.
* mark is increased by steps.
(14) After completing data transfer, ECU reprogramming starts sequentially
Select and load data
Select “Load RPG file” in main menu
Select a reprogramming data file
Esc key： Move back to main menu.
Remark:
-The data files are displayed in numeric order of data No.. (From big to small; new to old)
Reconfirm the data file No., and press Enter key to start transferring the data into V.C.I. built-in-memory.
Esc Key： Cancel
Progress is displayed on monitor
* mark is increased by steps
After completing data transfer, ECU reprogramming starts sequentially
Special case:
If V.C.I. has already stored the reprogramming data, select “ECU Reprogram” in main menu, and press Enter key
Reprogramming data file No. and program version No. in the V.C.I. memory are displayed for a few seconds, and then ECU reprogramming starts sequentially.
Reprogramming ECU…(VCI to vehicle ECU)
ECU parts No. and ROM-ID No. are displayed. Press Enter key to start reprogramming.
Note:
-Reprogramming must carry out on the condition of engine stop and IG switch on.
Do not disconnect harness/ turn off the IG switch during ECU reprogramming.
[Messages before/during reprogramming process]
a)“RPG data doesn’t apply to ECU”
Reprogramming stopped owing to the data in V.C.I. memory being not appropriate for the ECU.
?Note down the displayed ECU parts No. and ROM-ID.
?Restart V.C.I. by pressing Enter key, and confirm the matching of the data file No, which is displayed by reboot, and the ECU part No./ ROM-ID for reprogramming.
“ECU same as VCI, CK for new data” (CK; check) Reprogramming stopped because reprogramming has been already done
5 steps progress is displayed while reprogramming
Caution:
?Do not press any key during reprogramming automatically proceeding.
?Do not turn off V.C.I. power or IG switch during reprogramming.
STEP1: Saving the data to the back up memory.
STEP2: Erasing data in ECU.
STEP3: Writing reprogramming data
STEP4: Verifying the data between ECU and V.C.I.
STEP5: Erasing diagnosis code and back up memory
On completion of the 5 steps, new reprogrammed ECU parts No. and ROM-ID are displayed.
Turn IG switch LOCK（OFF）
Note:
Diagnosis code might be memorized in ECU if without turning IG switch Lock (off)
ECU reprogramming completed
Verify the system properly operated by starting engine. Enter key: V.C.I. restart.
