AFFECTED VEHICLES
2001–02 Diamante
PROCEDURE
CAUTION
BATTERY VOLTAGE (AS MEASURED AT THE BATTERY POSTS WITHOUT ELECTRICAL LOAD)
MUST BE 12.4V OR HIGHER IN ORDER TO REPROGRAM THE PCM.
1. Check the underside of the hood to verify that there is no label to indicate that this TSB
reprogramming has already been done.
2. Using the MUT–II scan tool, check to see if any DTCs are set in the PCM. If any DTC is set, follow
the appropriate DTC troubleshooting and repair instructions in the service manual.
3. Use the MUT–II to read the ECU part number as described below, then refer to Attachment A to
determine the appropriate ROM pack database number.
a. With the MUT–II connected, turn the ignition key to ON.
b. At the MAIN MENU, select “1. System Select” and press Yes.
c.
Select “MFI” and press Yes.
d. Select “Mitsubishi MFI” and press Yes.
e. At the OBD–II check code screen, press Yes.
f.
At the Readiness Tests status screen, press Yes.
g. At the MFI Main Menu screen, press S.
h. At the Check Code screen, press the right arrow " .

256 KBYTE IC Memory Card (red)
MB991717
ROM Pack (red label)
MB991701
Use the appropriate database listed below
“Engine Compartment/Control Module” Labels
Part No. MSSF–024G–00
NOTE: Reprogramming cartridges memory cards,and ROM packs are available from SPX/OTC by
calling 1–888–727–6672.
IMPORTANT
Dealers must update ROM packs as needed, depending on vehicle repair requirements for PCM
software updates.
For instructions on updating ROM packs using MEDIC, and for current database information:
1) From the MEDIC Main Menu, select “MUT–II ROM Pack Re–write.”
2) Select “ROM Pack Information.”
For assistance with updating ROM packs using MEDIC, contact the MEDIC Hotline at
1–800–846–7575 .
When updating the ROM packs for this bulletin, use the following passwords:

6. Install the red label reprogramming cartridge to the MUT–II. Then install the 256 KBYTE red
memory card and the red label ROM pack. Use the ROM pack with the appropriate database
number.
7. Reconnect the MUT–II. Connect both the 16–pin and the 12–pin data link connectors.
8. Turn the ignition key to ON.
NOTE: If the MUT–II displays “Error No. 11,” request a replacement from Standard Register at
(877) 227–6115, option 1.
CAUTION
DO NOT DISTURB THE HARNESS CABLES OR CONNECTIONS. INTERRUPTION DURING THE
PROGRAMMING PROCESS COULD CAUSE THE PCM TO LOSE DATA OR PREVENT FUTURE
PCM REPROGRAMMING.
9. Select “MFI / ELC A/T”.
10. If either of the following messages display, STOP! Do not continue with this procedure:
a. If the PCM has already been reprogrammed, the MUT–II will display “This ECU has already
been reprogrammed.” Do not continue with this procedure.

TSB–03–13–003
b. If the PCM was manufactured with the latest software update, the MUT–II will display “ECU
data for above part # and ROM–ID is not available.” Do not continue with this procedure.
11. If the MUT–II displays “Reprogramming is not possible on this ECU,” first verify that the correct
ROM pack is installed.
a. If the correct ROM pack is installed and this message displays, replace the PCM. Record this
MUT–II screen information and the ROM pack database number on the repair order.
If you replace the PCM, be sure to verify that the new PCM has the latest software. After
installing the new PCM, follow the instructions in Step 3 to read the ECU part number and
ROM ID. Then compare this information with the latest PCM software database information on
the Diamond Dealer Link and in MEDIC. Reprogram the new PCM if necessary.
12. If the PCM can be reprogrammed, the MUT–II will display, “Do you want to reprogram this ECU?”
Press “YES”.
