Hazard Warning Lamps
NOTE:
The hazard switch is integral to Integrated Center Stack (ICS), which provides a hard wired output to the BCM. Before performing any of the following tests, confirm whether the left and right turn signals operate satisfactorily. Then determine whether the other functions of the ICS are operational. If the turn signals are ineffective or operate improperly, or if the other ICS functions are ineffective, diagnose and repair those problems before attempting to repair the hazard warning lamps system.
| CONDITION | POSSIBLE CAUSES | CORRECTION |
|---|---|---|
| HAZARD WARNING LAMPS DO NOT FLASH | 1. Ineffective ICS. | 1. Test and replace the ICS if required. |
| 2. Ineffective BCM inputs or outputs. | 2. Use a diagnostic scan tool to test the BCM inputs and outputs. Refer to the appropriate diagnostic information. | |
| HAZARD WARNING LAMPS DO NOT STOP FLASHING | 1. Ineffective ICS. | 1. Test and replace the ICS if required. |
| 2. Ineffective BCM inputs or outputs. | 2. Use a diagnostic scan tool to test the BCM inputs and outputs. Refer to the appropriate diagnostic information. |
