Default How to test whether vibrator is broken

Hi, Sensation XE user here

I have sultanxda rom installed and vibrator is not working neither for calls nor for haptic feedback and notifications. I don't know if it worked on stock rom, becouse I forgot to test it before flashing sultanxda rom and I really don't wanna go back to stock rom just see if vibrator works there.

Now since this rom is rooted and comes with terminal emulator, is there a way to detect and test vibrator via command line? I know that android is just linux under the hood. In linux you can check your devices under /dev folder will the same work here and what should I look for?
