Toyota released a software update to fix a problem that caused the Check Engine Light to come on. Before the update, the computer would report a problem with the catalytic converter when there wasn't one.

    The check engine light comes on. It indicates the converter needs replaced inorder for the car to pass PA emission inspection.

    I checked with my local Toyota garage and they said there isn't a software upate to correct the faulty check engine light.

    Can someone give me specfic info that I can give to the garage?
