You say “premium” model?
is it a two three four five limited t3 t4 or tspirit ?

 

Really not sure. It's a 2010 with DU in the vin. It also has a Prius factory logo on the rear bumper skin. Also a 6 speaker sound system with a factory preamp under the seat. But no traction control module in/under the center console. I looked in front under the plastic near where the abs module is and all around the area. No traction control.

 

Is there a model indicator on the left side of the boot lid?
also since you state 2010 as the model year, which was the changeover year, is it the 1.5 engine (gen2) or 1.8 engine (gen3)

 

It's a gen 3 engine. Non lithium battery.

 

I think only the “five” had the module. The rest you had to do a dance with a routine “searchable on internet”

 

I've tried some of the dances. And there is a tpms reset button, tried that too. Actually now I just get a click when it's not happy.

 

So a little better. But, where is the tc module is still a question.
