O/D Off Switch
- Remove center console to access switch connector. Turn ignition switch to ON position. With O/D OFF switch released (O/D enabled), measure voltage by backprobing between O/D OFF switch terminal No. 3 (Green/White wire), No. 6 (Black wire), and ground. See Fig 1. Battery voltage should be present on terminal No. 3, and zero volt on terminal No. 6. Depress O/D OFF switch (O/D disabled). Zero voltage should be present on both terminals. If voltage is as specified, switch is functioning correctly. If voltage is not as specified, go to next step.
- Turn ignition switch to OFF position. Disconnect O/D OFF switch harness connector. See Fig 1. Check continuity between terminals No. 3 and 6 on switch harness connector. Continuity should exist with switch depressed. If continuity is as specified, switch is okay. Inspect circuits to ground and TCM. Repair as needed. If continuity is not as specified, replace switch.
