This recently occurs and often in the morning (cold?) when I drive out
of the house to drop
off kid at school (15 minutes away). While at school, if I turn off
engine and back on,
ASC light goes away. Is this normal? It's happening on a regular
basis now.
Now when I get out of work, same thing occurs. Something to do with
cold engine?

Appreciate any insight.

Thanks.

I doubt if the cold engine has anything to do with this. When the light
comes on the ASC is no longer working, not a good thing if you run into
any weather when taking the kids to school.

There are a multitude of things that can trigger the ASC failure.. from
a bad cable on the cruise control actuator (which is used to control the
throttle for ASC) to bad wheel sensors on the ABS system (which feed
data to the ASC part of the ABS controller.)

It will likely require a dealer visit to diagnose this. Hopefully there
are error codes stored in the ABS/ASC controller that will guide the
techs in diagnosing your problem.
