Transaxle 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 PCM to identify a state of change in the O/D OFF switch. The switch must briefly be cycled on all vehicles with an O/D OFF switch. This test is performed during the KOER self-test.
