Firstly, simply cleaning the wheel speed sensors will not make the problem go away if the ASC-T light is being illuminated because of a faulty wheel speed sensor(s). They will obviously need to be replaced if they are defective. That said, there is a chance that the light is being turned on for some other reason. Check all related fuses and relays, and then have the car scanned. If all fuses/relays and wheel speed sensors check out okay, it's most likely a faulty control module. You can have the wheel speed sensors tested, too.
