Stoplight Switch
WARNING: This page is about a different car, the 1996 Mazda Millenia and 1995 Mazda Millenia. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect stoplight switch connector. Using ohmmeter, check continuity between stoplight switch connector terminals. See Fig 1 . With brake pedal depressed, continuity should exist between terminals "A" and "B". With brake pedal released, continuity should exist between terminals "C" and "D". If continuity is not as specified, replace stoplight switch.
