Hazard Warning Switch
- Ensure HAZARD and TURN fuses are good. Ensure flasher is good. For turn signal flasher testing, see STEERING COLUMN SWITCHES article. For turn signal flasher location, see TURN SIGNAL FLASHER LOCATION table. With hazard warning switch removed from instrument panel, ensure battery voltage exists at switch wiring harness connector terminals No. 8 and 10 (Avalon, Camry, Celica and Supra) or terminals No. 6 and 7 (Corolla and Tercel). See Fig 1. If battery voltage does not exist, check/repair fuses and wiring harness circuits. If battery voltage exists, go to next step.
- Using DVOM, ensure switch continuity exists between indicated terminals with switch in specified position. See HAZARD WARNING SWITCH CONTINUITY table. If continuity is not as specified, replace switch. If continuity is as specified, check wiring circuits. See WIRING DIAGRAMS .
