Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Hazard Flashers
When the switch for the hazard flashers is activated, the contact in the switch is short-circuited, grounding terminal 21 in the ICE. The ICE supplies voltage to the left and right direction indicator lamps and to the indicator lamps in the main instrument, which start to flash simultaneously. When the switch is activated, the light in the switch also comes on and starts to flash with full strength. If the hazard flashers are activated for a lengthy period, the flashing frequency is changed to be more off than on. This is done to save the battery and to prevent the ICE electronic control module from becoming overheated. See Fig 1 .
