Pops848 Posted December 30, 2017 Share Posted December 30, 2017 Hey all, I've done some searching and a little fettling with the my partner's sister's Ka, however I cannot work out what is at fault and I was hoping someone might be able to help please. it's a 2010 Ford Ka, and the centra locking will not lock the car, it will unlock it but not lock it. The door ajar symbol is always on so I'm assuming the car has a faulty sensor but I cannot work out where it might be. By the looks of it there is no boot light (unless I've missed it) Both front doors activate the interior light as they should (are they connected to door ajar light on the dash?) The problem only started when she used the boot one day, I've replaced the boot latch and this doesn't resolve the problem The boot unlocks on the remote so that seems to be getting power so no breaks in the wiring? I can't see a bonnet switch I've tried putting the car into GEM diag mode but it doesn't seem to want to do this (don't know if Ka's let you do this?) When locking the car she has to do this manually with the key, if you use the remote it flashes indicators 9 times but does not lock, however you can unlock from the remote on all doors. Any suggestions would be appreciated! I assume a simple OBD fault scanner won't pick up faulty sensors like this? Thanks Ads Quote Link to comment Share on other sites More sharing options...
isetta Posted January 3, 2018 Share Posted January 3, 2018 does the door ajar light also include the boot (ie. does the car have a separate light to warn when boot ajar or is it just one light that covers both doors and boot? it stops you locking on remote because it thinks something is open. does the boot catch have a microswitch in it / on it to sense when closed properly. I do not know on this car is the switch to sense when closed properly is attached to the catch or is somewhere else. could it be it needs the catch adjusting slightly to make it close tighter or needs slamming down harder?

Motorkit Posted February 10, 2019 Share Posted February 10, 2019 Hi I've got a 2009 Ka exactly same fault did you solve it and how may I ask. Quote Link to comment Share on other sites More sharing options...
frund Posted April 16, 2019 Share Posted April 16, 2019 Probably the door closed sensor which is attached to the door lock. This will stop you locking the doors, a lock/ unlock situation. Often a dirt problem with the switch. Use WD40 in abundance into the door lock from all angles the surplus will run out the bottom of the door. Work the lock many times respray up, back of, bottom. Leave for a week or so and spray with liquid grease. This cured mine after checking door to A frame harness. Quote Link to comment Share on other sites More sharing options...
