Plugin Location Accuracy Ionic 2

I'm using an API Location Accurancy Ionic v2 follows the code:

cordova.plugins.locationAccuracy.canRequest(function(canRequest){
    if(canRequest){
        cordova.plugins.locationAccuracy.request(function (success){
            console.log("Successfully requested accuracy: "+success.message);
        }, function (error){
           console.error("Accuracy request failed: error code="+error.code+"; error message="+error.message);
           if(error.code !== cordova.plugins.locationAccuracy.ERROR_USER_DISAGREED){
               if(window.confirm("Failed to automatically set Location Mode to 'High Accuracy'. Would you like to switch to the Location Settings page and do this manually?")){
                   cordova.plugins.diagnostic.switchToLocationSettings();
               }
           }
        }, cordova.plugins.locationAccuracy.REQUEST_PRIORITY_HIGH_ACCURACY);
    }
});

The "canRequest" function always returns false and does not request to be able to activate.
