Did you hook the battery up backwards the first time? I think so. But either way you have sent a voltage spike to the EHPAS module(electro hydraulic power assist steering) and fried it. It will require replacement and a program. The part and the programming must be obtained from the mazda dealer.

Ok, sorry. Yeah sometimes that's all it takes to create a voltage spike, I see it quite often. Please let us know how it turns out and thank you for choosing two car pros.
