Hazard Lamps Malfunction

The hazard flashers may be activated in any power mode. The indicator hazard flasher module controls the vehicle indicators and hazard warning flashers based on inputs from the indicator/multifunction switch. When the hazard switch is activated, ground from G302 is applied through the indicator hazard flasher module ground circuits to the indicator hazard flasher module indicating the hazard flasher ON request. The module will then apply a pulsating battery voltage to the left and right indicator lamp control circuits, cycling all indicator lamps, and both instrument panel cluster (IPC) indicator indicators ON and OFF.

1. Ignition ON, command the left and right indicators ON and OFF using the indicator/multi-function switch. The exterior indicator lamps and the IPC turn signal indicators should turn ON and OFF when changing between commanded states.

⇒	If the system does not perform as specified, refer to Indicator Lamps and/or Indicators Malfunction .

2. Activate the hazard warning flasher switch. All indicator lamps should cycle ON and OFF until the hazard switch is turned OFF.

⇒	If hazard lamps are always ON or always OFF, replace the indicator/multi-function switch.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
