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.
Ambient Meter
The ambient meter is the background color of the speedometer. It changes color based on data the PCM receives from various control units and sensors. The PCM calculates this data, forms an Eco drive profile, and then sends the profile to the gauge control module via F-CAN. When the gauge control module receives the Eco drive profile data, it can respond by changing the background color of the speedometer. During low fuel economy, the ambient meter is blue; at medium fuel economy, the meter is blue-green; and at high fuel economy, it's green.
