I have my Father's 2000 / 2001 three door 1.4 VVti Corolla which handily has a Euro 4 motor so will make a run around for, Steph until we get around to replacing the A4 which does not meet the ULEZ requirements.
Slight problem with the interior light on the Corolla which also effects the remote central locking as it thinks a door is open so will not lock the car from the fob, it will however lock from the drivers door key or the interior door lock / unlock switch.
I have around three volts on the driver's side door pin which shorts to ground when the door is closed, however the passenger door pin has less than a volt. I am having difficulty finding a legible wiring diagram for the car but from the ones I have seen on the net the door pins seem to connect to the integration relay behind the fuse box, various diodes and a feed from the door control module.
I have changed the module behind the fuse box for a used ebay one (obviously no way of testing because I don't have a workshop manual) but no better it may also be faulty, don't know.
So anyone with experience with similar aged Toyota electrics seen this, there seems to be quite a bit of inconclusive info on the net but as yet I have not seen anywhere that discloses where the 'Door courtesy' diodes are located or what to voltages / signals to expect on the integration module or the door control module.
My gut feeling is that the door control module is good as it will lock unlock from the door switch.
FWIW I am much more at home with the Audi or BMW where I can just look at the inputs on a pc, who was it that said older electrics were more reliable?
Any help or pointers would be much appreciated.
