94, 3000gt sl , problem with ECS

my ecs is messing up. every time on a bumpy road it automatically turns to sport mode and the light in dash board that says sport starts flashing. after that i can not put it back on tour mode by pressing the ECS button. when i shutoff the car and start it again it goes back to tour but than does the same thing if i hit a bumpy road. i had the alignment done yesturday and its been doing it since. i am not sure what could be wrong.
any suggestions.

the alignment place also replaced the outer tie rod. not sure if they hit anything while changing or something else. please let me know if anyone knows about ECS problems like these.
thanks alot
