My ATSC indicator light is activated. Originally it was intermittent, now it is on full time. When I took it to the repair facility they put it on the computer and were unable to definitively determine what needed to be replaced. Apparently there is both a rotational sensor device [under the carpet - driver side] as well as an ATSC module that is under the hood that could be the culprit. Can anyone suggest a protocol for trouble shooting the problem? Thanks.
