I'll give it a try a bit later when I have time, I suspect there may be a problem within the can network between the door and body ecu's, Would anyone by chance happen to know how to reprogram a door control transmitter, it is integrated into the ignition key and has only a single button on the upper corner of the key... Thanks again

Yes mine is integrated into the latch, what I don't understand is why only after leaving the door open for a few minutes, does the courtesy light come on and the door open indicator on the dash come on, then I close and open several times after they all work perfectly, once I leave the door closed for some time then open again, the symptoms occur again.

Good day to you all, I have a 1998 jap import 3.0l toyota harrier, which is almost identical to the lexus rx300. the problems i am experiencing are as follows: - Door ajar light only comes on after leaving the drivers door open for 3 -5 minutes, once the ajar light comes on i can open and close the door several times and it will be working perfectly, once door is left closed for a period of time it stops working. meanwhile the rear passenger doors work perfectly. its not only the cabin light that is affected by this but also the automatic headlights. i have stripped and cleaned the contacts in the door lock mechanism to no avail, same symptoms occur. -my door transmitter is not working even after replacing the battery. i have bridged the diagnostic plug to retrieve any flash codes, but there are none present. Please can anyone help with information to the electrical diagnosis of these faults. or if they have come across something similar. i am fairly technically able so any and all advice is welcome. PS, my local dealer here is not to jacked up on diagnostics so would prefer to do it myself. Thank you
