Hazard Warning Lamps
NOTE:
The hazard switch is integral to the instrument panel switch bank, which provides a hard wired output to the TIPM. 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 instrument panel switch bank are operational. If the turn signals are ineffective or operate improperly, or if the other instrument panel switch bank functions are ineffective, diagnose and repair those problems before attempting to repair the hazard warning lamps system.
