MUT-III ECU Rewrite ROM Data from 2009 to 2021

 

Notice:

This function enables the program installed in ECU to be reprogrammed using M.U.T.-III.
As VIN or other setting information on ECU is not erased by this reprogramming,you do not need to rewrite VIN.
You can not make ECU Reprogramming with V.C.I.-Lite stand-alone

 

Process Flow Chart
Reprogramming by K-Line communication system
-There are 7 different ways for ECU reprogramming as shown below.
-Procedure (a) is recommendable due to the most simple in operation.
-File extension code is “xxxx.rpg”.

Reprogramming by CAN communication system
-This is the only way for reprogramming by CAN communication system.
-This procedure allows you to select an arbitrary system (ECU) to reprogram as required.
-File extension code is “xxxx.cff”

Equipments

Necessary parts for ECU reprogramming are as follows

Remarks
*1:Vehicle which is only equipped with a 16 pin diagnosis connector.
*2:Vehicle which is equipped with 16 pin and 13 pin diagnosis connector.

 

Data preparation on PC from Update CD-ROM
9-3-1. PC Update Operation (CD-ROM –> PC)< CASE 1 >
When an Update CD-ROM of ECU reprogramming data is distributed newly, insert the CD-ROM into CD-drive on PC.
Press Special function button on STV Top Menu.

Select System Function tab,and press ECU reprogramming button.

The message “Please update to a new database file.” is displayed when the new Update CD-ROM is recognized.
Press “OK(tick)”button.

The message “Please wait!” is displayed during progress.
When complete the updating, the message disappears.
You can remove the CD-ROM from PC.

< CASE 2 >
By inserting ECU Reprogramming data CD-ROM in the CD-ROM drive of a PC, update of ECU Reprogramming data starts automatically. And by operating it according to the message displayed, it is possible to update the ECU
Reprogramming data in M.U.T.-III in the newest state.
After terminating M.U.T.-III, insert Reprogramming data CD-ROM in the CD-ROM drive of a PC.

Confirmation of update
Click the “Yes” button, update of the ECU Reprogramming data in M.U.T.-III is started.
Remark:
An end message changes by the kind of data updated at this time.

Update finished

(Case A)
Update was finished. Click the “OK” button, update of ECU
Reprogramming data is ended.
Double-click the M.U.T.-III icon displayed on the desktop to start up the system.
(Case B)
Update was finished. Click the “OK” button, the PC is rebooted automatically.
After rebooting the PC, Double-click the M.U.T.-III icon displayed on the desktop to start up the system.
Update is unnecessary
The ECU Reprogramming data in M.U.T.-III is in the newest state. It is not necessary to update ECU Reprogramming data. Click the “OK” button, this update application is ended.

 

Reprogramming Operation ( V.C.I. alone )
(Not support to V.C.I.-Lite)
Data transfer (PC –> Memory Card)
Start up the M.U.T.-III system.

Caution
-Do not remove the memory card from PC.

Select a memory card drive, and press button to start transferring.

Press ok button when the message “It transfers data to the memory card. Are you ready?” appears
Data transfer
The progress bar is displayed during the transfer.
The data transfer is complete.
Press OK button.

Before you remove the memory card, click the below icon for removal of the adaptor.
Click the [Eject ATA Device] or the other appropriate device.

 

After displayed the message “Safe To Remove

Caution:
Do not remove the memory card away unless complete above method or turn off the PC.

Equipment Set-Up
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)
Connect M.U.T.-III Main Harness B (MB991911) or A (MB991910) to V.C.I. main unit securely.
Note:
Select appropriate harness by instruction below.
– Main harness A: For vehicle only equipping 16 pin diagnosis connector.
– Main harness B: For other vehicles.
– Adaptor harness (MB991855): Outlander, Montero (after ‘02MY) (To connect Main harness B and 13pin diagnosis connector)
After verifying the ignition switch position at LOCK (OFF),connect the M.U.T.-III Main harness B or A to the diagnosis connector.
(4) Turn Ignition switch on, and turn V.C.I. main switch on.
(Do not start the engine)

 

Data Retrieval (Memory card –> V.C.I.)

Automatic Data Retrieval
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.

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.
(a) “No update data in PC card” This message appears if no pertinent reprogramming data exists. No data will be transferred.
(b) “ECU at current level of VCI”
This message appears if the ECU has been already reprogrammed. No data will be transferred.
Progress is displayed on the monitor.
* mark is increased by steps.
After completing data transfer, ECU reprogramming starts sequentially.

 

(b)Select and Load Data
(1) Select “Load RPG file” in main menu by key, and press
Enter key.

Progress is displayed on monitor
* mark is increased by steps.
After completing data transfer, ECU reprogramming starts sequentially.

(c)(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 (V.C.I. –> Vehicle ECU)
ECU parts No. and ROM-ID No. are displayed.
Press Enter key to start reprogramming.
ESC / key : restart V.C.I.
* : By pressing key, immediately move to next.
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.
b) “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
