Transfer the reprogramming data from the laptop to the memory card.

Remove the memory card from the laptop and install it in the VCI. Connect the VCI to the vehicle.

Select "Automatic Programming (K-line)." For reprogramming details, refer to TSB-03-00-01.

It will take up to 20 minutes to complete the reprogramming.

NOTE:

If the message "ECU at Current Level of VCI" appears, the PCM did not reprogram. Verify that the ROM ID is the same as the ROM ID listed in
Attachment A.

If the ROM ID is the same as the ROM ID in Attachment A or higher, the PCM has already been reprogrammed for this concern.

If it is not, verify that the correct database update is in the MUT-III and was transferred to the memory card, and that the memory card is properly
installed in the VCI.

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.
