Car sensor problem

Rear hatch is locked or unlocked with a key. (if equipped) • To open the rear hatch, insert the key into the lock, turn it to the unlock position and pull up the rear hatch by pressing the handle (DOOR). You can also lock/unlock the latch (but not release it) with the central door lock system. • If unlocked, the rear hatch can be opened by pressing the handle (DOOR) and pulling the hatch up. • To close the rear hatch, lower and push down the rear hatch firmly. Make sure that the rear hatch is securely latched.

The door switch isn't being pushed in far enough when the hatch is closed. The wire going to that switch may be shorted to the body somewhere, too.

Be sure all doors are closed securely including rear hatch. If that still happens one of the door or rear hatch electrical switches may need to be adjusted. If the car has been struck lately, start looking in that area.

Sounds like the sensor inside the rear latch. Most vehicles don't use an actual door switch these days.

The better solution is to fix the hatch so it closes tightly. The latch hooks on to an adjustable loop. The hatch closes on to the rubber seal: if this is damaged, fix or replace. There may be some adjustable rubber bump stops as well. Lastly, check that the door ajar sensor is not loose.

You will need to spray each door latch including the rear hatch liberally with WD 40 or spray lubricant on the latch and open and close each door several times after spraying. This will usually be sufficient to get the door sensors to detect when you have closed the doors. If this doesn't do it, it will hep to figure out which door is intermittently causing the door ajar light to stay on.

the switch on the **** of the door hatch is no making contact with the door or mulfunction switch.

You need to tighten the lock mech on the boot lid. this will close the boot just enough more to turn the light on. It's no biggy, you might need a star driver depending on bolt head. move it into the boot lid approx 4mm to start. then 1mm until 10mm. if no joy then it may be the sensor.

This switch is in the lock it self. Push the lock into place with a screw driver (use the screw driver like the bar that the lock comes down onto)and the light should go off it you have all the wires still intacked.
