Did more careful test drive ...all same EXCEPT ASD light did NOT come on during stop, but DID come on after releasing brakes and accelerating as passing 1200 rpm then went out.

I also noticed the ASD would occasionally kick in while cornering at low speeds (it doesnt operate at anything over about 17-18 mph).


I pulled the ASD module and got same results, except the ASD operating light (triangle) did not illuminate at all and there was no ASD actuation.
