2002 Ody TCS light.

Just bought this van about a month ago. I believe the seller hid quite a few problems as they're starting to surface.

One of the problems is the TCS light keeps coming on. It stays on until I clear it with a OBD scanner. Any ideas?

I have been told the trans is going out , my 01 is doing the same thing . take the battery cable off for an hour , it should reset everything including the radio stations
