If a diagnostic code of 268-02 Check Programmable Parameters is generated, program any parameters that were not in the old flash file. b. Access the “Configuration” screen under the “Service” menu in order to determine the parameters that require programming. Look under the “Tattletale” column. All of the parameters should have a tattletale of 1 or more. If a parameter has a tattletale of 0, program that parameter.
