Turnips dad - For the Toad to recognise a door has been opened you need to ensure the Toad is connected up to the door opening pins. These are already in place and require a Diode to be spliced in due the possibility of having a "convenience light" circuit in the car – This way, if you have it you will keep the convenient light system. If you do not have a diode you will need to unplug the convenient light system on the door push buttons – otherwise you will get false alarms.
If you want to check the diode operation remove each switch and check that the diode only passes voltage in one direction, if it does not then this could be the problem.
Thanks for your reply, I tried this today and it is not the problem,
so don't know what else to try, may just end up taking it somewhere for someone to take a look at it for me
