Transmission Control (O/D OFF) Switch Test
WARNING: This page is about a different car, the 2003 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
This tests the ability of the powertrain control system to detect a state of change in the O/D OFF switch. The switch MUST briefly be cycled on all vehicles with the O/D OFF switch. This test is done during the KOER self-test.
