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

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.

Page 3 of 5

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”.
