C280 A\C Auxilliary fans Controller ssue

[Bzoo]

Good morning. Yesterday when I was trying to pull codes from the dash controller on the C280 I might have disabled the electric fan circuit. When I depressed the REST and Ec switch the controller went into Diagnostic mode. However when I depressed the EC button again the controller went into a different mode only on the left side of the display and that broke down further into three different subsections that recognized values in dashes , blanks or 1's which could be changed using different buttons on the controller. . I did not intentionally change any settings here but I may have. The electric fans have not come on since. Is there a reset protocol for the controller.
Thanks.
