Hello everyone. I was attempting to install a remote start and keyless entry (Valet 561r) on a 2009 Ford Focus. When testing the door lock feature the cars headlights, parking lights, and tail lights came on and won't go off. I had the driver door open when testing the locks and I locked and unlocked the doors twice. After the second time unlocking the doors that is when the lights came on and won't turn off. I've completely removed the Valet 561r and the lights are still on. I unhooked the negative battery cable to try and reset the computer but that didn't work either. Does anyone have any ideas what I may have done to this thing? Thanks

Will

Did you attempt to connect the parking lights to the keyless module?  I have no idea on the focus, but I have seen this exact problem on the SuperDuty trucks.  The problem is that the wire at the light switch is negative in polarity.  If an installer does not pay attention to the polarity, and connect a positive voltage to that wire, it burns a trace on the circuit board of the light switch.  If this is your case it is very easy to repair.  you do not need to buy a new switch.

Innit wonderful I only have to do the indicators oh and here we go someone installing without prior testing. 06 Focus over here uses acombined Jem/Fuse box and the lock wires come out of a plug underneath but are the same colours as previously, black /orange to lock and BLACK/ green to unlock, low current neg. If the valet unit has only a 2 wire lock output, green is lock and blue is unlock BUT insert diodes (1N4XXXX) with the diode bands towards the R/S

I tested all wires before making any connections since the newest wiring diagrahm I could find was for an 08. I tested the wires at the light switch and verified it was a positive wire before connecting to it for the parking light flash. I also tested the lock and unlock wires and verified they were negative. The lock and unlock wires were located at a  plug below the fuse box. 

i am an idiot, how do I fix the circuit board or what do I check to see if I messed up the circuit board?

thanks

Will

Also unplugging the light switch doesn't affect the lights.

Like I said earlier I am not at all familiar with the light switch in the focus.  On the SuperDuty trucks, simply remove the switch from the dash, there are 3 screws in the back of the switch.  Remove them and remove the back cover.  There are several very small traces of silver foil on the circuit board.  you will have to look very closely to see if one of them is open.  It basically becomes a fuse and breaks at the smallest point of the trace.  If you have an old computer IDE or floppy cable laying around, one of the conductors makes a great jumper to jump the open trace.  you have 2 choices, one is to just solder a piece of that wire to the component to the left of the open and solder the other end of the wire to the next component to the right.  Second choice is to strip a  few inches of the wire, twist the exposed wire to make it more manageable, heat it up and apply solder to the entire length of the exposed wire, apply some solder to the trace that opened, now solder the jumper to the trace and cut off the excess wire.

Thanks for your help. The headlamp switch is the problem. Don't know if I'll be able to resolder that wire but thank you again for the information.
