Check your fluid level. It is behind the left side trunk carpet. There is a circle molded into/on the fluid tank. Top has to be fully stowed (down) to check the level.

Switches will will set a code if they are pressed too long. Like when you keep pushing the button waiting for it to do something.

Both of my open & close switches had shorted codes. Filled my fluid up and cleared all the codes. All was good until the fluid ran low again.
