Vauxhall Corsa wiper motor throwing out gearbox ecu

My wiper motor started making a knocking noise and won't return properly, carried on driving and all lights on dash lit up and F flashed up on gear selection and car stopped, had to wait a few minutes to be able to start car again, no problems with car when not using wipers. Would the wiper motor problem cause the gearbox ECU problems or is this the start of another problem
