Eco button possible problem

I have a 2015 Equinox LT and I'm getting codes P15A1 and P159F. Both have reference to the Eco button. Any solutions?

Those 2 codes together usualy indicate high resistance. Measure at switch power, terminal 3 to signal, terminal 4 (266 - 294 ohms). Terminal 3 to Ground Terminal 1 (1914 - 1562 ohms). Button depressed: termiinal 3 to Ground terminal 1 (486 - 538 ohms).
Any out of range, replace switch.
