This is the box which fits in the back left corner of the spare wheel well in the boot of the car. If your parking system is not working this part may well be the problem.
To test the module is working, engage reverse gear with your ignition on (engine off)
and check the reversing light is on.
Put your ear to each of your sensors - sensors which are working will make a faint, audible clicking sound. If none of the sensors are clicking then it is a very high probability that the module is at fault or the wiring loom.
If any of sensors are clicking then the module will be OK, you will only need to change the sensors that do not work.
