Central Locking on 2008 KX-S

[m0bii]

Hi Fellow Kluger Owners

I have been a proud 2008 Kluger KX-S owner for 18 months now and have been puzzled by the intermittent operation of the central locking via remote key fob.

It started about 10 months ago when one day I went to lock the car with the key fob and it wouldn't work - key was fine and all doors locked & unlocked OK. It has had several trips back to the dealer and had a new ECU fitted but still the problem came and went, for weeks at a time.

I have now discovered why & wondered if others could confirm if it is a bug in the design or if it is only my vehicle.

So here it is then..........

One day I got out of the car and happened to notice that the power LED on my Tom Tom 720 was still illuminated after I had removed the key from the ignition, which I thought was unusual as it normally loses power to the 12v Acc sockets when the key is switched off and removed. This happened to coincide with the time the wireless key fob wasn't working - I don't know why I thought to do it but I removed the 12v plug from the socket to see if it made any difference - It didn't. Some days later I was telling my wife that I had noticed this and she remarked "What about that rechargeable torch you have plugged in at the back". I laughed it off and told her I had already tried it - I hadn't but I had been thinking about it. Some days later I remembered to remove it and would you believe it - The problem went away!!!

I have since reconnected it and the problem returns straight away.

I haven’t tried plugging in anything else but the problem has been dormant ever since I last plugged in the torch about 10 weeks ago.

I am an Electronics Technician by trade and can only assume that there is probably an issue with some residual current flowing through that accessory socket that is latching the relay or circuit that switches the power to the 12V circuit - Normally the central locking on the wireless key fob won't work whilst the key is activated in the ignition and the 12v sockets are live.

Just thought I would share this with you and would be interested if anyone else has had the same problem or can replicate it.

I haven't had the issue with the central locking as you've described, but have noticed the same phenomenon you mentioned with the LED on the TomTom. It occurred when I had a rechargeable device plugged into the auxiliary socket and turned the ignition key to off. I came to the same conclusion as you, that the device must output a residual current into the circuit. The FOB does lock/unlock the doors when the key is in the ignition (or at least mine does anayway).

new ECU??
