    Here is how to get some vital information about the A/C system.

    1. Start the car

    2. Put both sides temp settings at 72(or the celcius equivalent)

    3. Push and hold the REST button till you get a 1 in the left side

    4. Push the left AUTO button to scroll forward and right auto button to scroll back.

    5. Let the car run 3 minutes before pulling data to ensure more accurate data.

    For AC diagnosis you only need to be concerned about codes 1 through 8
