I recently asked about a sound that I was hearing for 1-2 seconds just after I start the engine.
It was snowing here so going to work in few places the traction control kiked in and made the buzzing sound, which is exactly the same as the buzzing sound I have been hearing for 1-2 second after start up.
Is this normal?

 

This sound happens just when I let the key go after kranking

 

i hear an electrical buzz everytime i start from a stop, always imagined it was something with the abs computer? i ignore it haha, everything works!

 

That is the ABS doing a self test.
Your T/C makes the same noise because it uses the ABS to stop wheel spin and increase traction.

 

I am glad it is nothing to worry about
