I am unable to program ODB 2013 and newer Injector Trim Codes?

After scanning and applying the Injector Trim Codes, Tech Tool would not allow the program to work and then Tech Tool would lock up.

ANSWER:

Please update Tech Tool to version 2.7.55 using the Client Update.  If using Tech Tool version 2.6, please perform a new installation by using a Tech Tool DVD or USB Flash to upgrade to 2.7.55.
