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”.
13. The MUT–II will display this screen as it reprograms
the PCM. It will take approximately 15 minutes to
complete.
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.
14. When the screen displays “Completed,” press “C”.
If reprogramming does not complete, repeat this
process as instructed on the MUT–II screen.
To verify that the correct reprogramming has been
made, the ROM ID number will display on the
MUT–II screen. Note this number. The table in
Attachment A lists the ECU part numbers, ROM ID
numbers, and vendor codes that should display after
reprogramming.
15. Turn the ignition key to OFF and disconnect the
MUT–II. Reprogramming is complete.
NOTE: On vehicles with TCL, the TCL light may come
on during reprogramming. To reset, turn the key off
for at least three minutes, then turn back to ON.
