Well if you can help me figure this out, Lottie has agreed (she hasn't really but I don't think she'll mind) to give you one! Free of charge. Electronic central locking...YAYYYYYY Ok, so the breakdown is, my windows work both up and down, my central locking locks on the button but doesn't unlock, and both doors will lock with the key but the passenger door doesn't open with the key in the driver's door... So basically the central locking doesn't work with unlocking. I've done a reading on all the wires and tried what I thought would be the solutions but nothing. If imagine these connectors go from 1-6, count from left to right, top to bottom, (#2 isn't actually a wire) And the colours if anyone understands the concept of Toyota colouring... (#2 isn't actually a wire) Colours of wires are; #1 RED #2 Not a wire lol #3 GREEN #4 RED with WHITE trace #5 BLACK and WHITE #6 GREEN with RED trace I've broke it down into 3 sections. 1) What the wires are doing with no buttons pressed. #1, Earth #2, N/A (not a wire lol) #3, Earth #4, Very weak 12V #5, Earth #6, Power (Reading about 10V) 2) What the wires are doing when the LOCK button is pressed #1, Earth #2, N/A (not a wire lol) #3, 12V POWER #4, Very weak 12V #5, Earth #6, EARTH (If I keep the power probe on the pin when button is pressed, the locks keep reciving power until I remove it or give it a 12v and then the locks will "relax". excuse my technical language lol) 3) What the wires are doing when the UNLOCK button is pressed. #1, Earth #2, N/A (not a wire lol) #3, Earth #4, EARTH #5, Earth #6, Power (Reading about 10V) Judging on the layout of the wires, I think #1 and #4 are for unlocking, #3 and #6 are for locking and #5 is just a constant earth. So I figure the problem is with wires 1 or/and 4. Although #4 does earth when the button is pressed... Logically (to me) I thought when the button was pressed if #4 becomes an earth, #1 should become 12v? So I tried giving it 12v both with the button pressed and not pressed and it does nothing. Can only assume its down to wire 1 being gay, or wire 4's weak 12v? A relay? Although locking works so lol.... Baffled!!! Any help would be really really appreciative.
