Hazard Warning Switch: Description and Operation
Description
DESCRIPTION
The hazard switch (8) is integral to the instrument panel switch pod (also known as the center console switch unit, Switch Bank Module/SBM, Upper
Control Panel/UCP or OBF) (2), which is located just below the heater and air conditioner controls in the center bezel (1) of the instrument panel. A red,
stencil-like International Control and Display Symbol icon for Hazard Warning identifies the hazard switch button. The remainder of the hazard switch
circuitry is concealed within the instrument panel switch pod.
The hazard switch button has panel lamps dimmer controlled illumination for night visibility. The switch button latches to a slightly lowered position
when the hazard warning system is activated and the push button features a Light Emitting Diode (LED) unit and a small plastic jewel to give the vehicle
operator an indication when the hazard function of the switch is currently active. The switch button unlatches to a position flush with the other push
buttons in the switch pod when the hazard warning is deactivated.
All of the circuitry and components of the hazard switch are contained within the instrument panel switch pod housing. A single connector receptacle is
integral to the back of the switch pod housing. The switch pod is connected to the vehicle electrical system through a dedicated take out and connector of
the vehicle wire harness.
The hazard switch cannot be adjusted or repaired and, if ineffective or damaged, the entire instrument panel switch pod unit must be replaced.
