TCS Light on
 

I have a 2005 Honda Accord V6 3.0L automatic. I recently had my (driver-side) air-blend motor/actuator replaced at a local shop. While driving home I noticed the TCS light and the adjacent triangle-with-exclamation light on. The shop is telling me it's just a coincidence that the light came on after the air-blend motor was replaced and that it has nothing to do with their repair job.

I find that a bit hard to believe and would like to hear from the experts on here.

Thanks.
