Note the sonar sensor locations in a Toyota Tundra.

Some 2014-2015 Toyota Tundra trucks equipped with Clearance Warning Sonar and steel bumpers may exhibit a condition where the CWS activates without an object in the detection area. An updated sonar sensor retainer is available to address this concern. The new retainer is available as P/N 89348-0C011. The old P/N is 89348-0C010.

Inspect the color of the sensor retainers. If  the sensors are black, replace. If white, the truck is already equipped with the revised retainers (in which case, further diagnostics are needed).
