ABS Motor Run

I have a 2001 Sebring with a 2.7 engine with about 60k miles on it. A noise started the other day coming from under the car. I am a mechanic by trade in the airline industry. After describing the noise to some co-workers, it might be the ABS hyd motor starting up. It sounds like a motor running and you can feel a hum when it is running. It runs for a few seconds then shuts off. It will do it occasionally while I am driving and it also might do it while the car is stopped, even in park. This is my first car with ABS, so I am on the "learn as I go" with this system. Any thoughts to this symptom?? If it is an ABS motor, what would cause it to run and why? Thanks for any feedback Jon

If it has ATC (Automatic Temp. Control) and is like the LH cars, there may be a fan that runs intermittently to sample air, and specifically runs for a few seconds when the engine is shut off. Could that be what you're hearing?

From personal experience (with my own cars) and reading forums, I have learned to ignore posters' comments about where they think noises are coming from as perceived from the driver's seat. 9 times out of 10, the noise is coming from somewhere totally different than the owner (whether me or someon else) originally thought. It's not even a conscious thing anymore - I just totally block it out without even realizing it. Hence my suggestion. I have seen many posts by owners of LH cars almost identical to the OP's (with the exception of guessing that it was somehow related to the ABS motor), and it has almost always turned out to be the ATC fan motor causing the noise. It's just a suggestion.

Could very well be.
