the wrong route

Same coordinates tried in Google map website,It is giving correct way

Where is the problem? Sending all the waypoints, origin and destination correctly. The coordinates are from tracking devices. only some cases showing wrong route like this.

var directionDisplay;
var directionsService = new google.maps.DirectionsService();
directionsDisplay = new google.maps.DirectionsRenderer();     
directionsDisplay.setMap(map);
var first = new google.maps.LatLng(23.6231225,58.5589985);
var second = new google.maps.LatLng(23.6235491666667,58.5591366666667);
var third = new google.maps.LatLng(23.6236481666667,58.55882);
var forth = new google.maps.LatLng(23.6209141666667,58.5476361666667); 
var i = 0;
var start = StartlatDir[i]+','+StartlongDir[i];
var end = EndlatDir[i] + ',' + EndlongDir[i];
var request = {
    origin: start,
    destination: end,
    waypoints: [{ location:first, stopover: false },
        { location: second, stopover: false },
        { location: third, stopover: false },
        { location: forth, stopover: false }],
    optimizeWaypoints: false,
    travelMode: google.maps.DirectionsTravelMode.DRIVING,
    unitSystem: google.maps.UnitSystem.METRIC
};
directionsService.route(request, function (response, status) {
    if (status == google.maps.DirectionsStatus.OK) {
        directionsDisplay.setDirections(response);
        var myRoute = response.routes[0];
        var txtDir = '';
        for (var i = 0; i < myRoute.legs[0].steps.length; i++) {
            txtDir += myRoute.legs[0].steps[i].instructions + "<br />";
        }
    }
});

Answer 1

The DirectionsService is very sensitive to waypoints near exits (or on the wrong side of the road).

Waypoint 4 (23.6209141666667, 58.5476361666667) makes the route take the exit.

Moving it further along the road to (23.620315,58.5471) gives the expected route:

or removing it completely gives the expected route
