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.
Circuit/System Description
The head-up display (HUD) dim down switch is a momentary contact switch that adjusts the HUD display brightness. The HUD dim down switch controls the intensity of the brightness. The HUD senses when the dim down switch is active and adjusts the display brightness until the desired intensity is attained. When the HUD illumination reaches the minimum intensity, the HUD will turn off the display by the next dim down switch input. The HUD does not have a separate OFF switch. The HUD is turned OFF using the dim down switch. When the HUD dim down switch is pressed and the ignition is in the RUN position, the dim down switch signal to the HUD is low. A press and hold of the dim down switch greater than 1 second initiates a smooth decrease in the HUD intensity until the switch is released or the HUD is turned OFF.
