Centre console lights not turning off, can’t turn radio on or off without key in

[Illusions144]

Hi all,

My Ford Fiesta has thrown up the strangest fault it’s had so far.

It’s an 09 plate, so fairly old now.

I noticed tonight that when I lock it, the centre display lights (little screen displaying the time and date and buttons that have lights behind, cd, radio, numbers etc) aren’t turning off.

I also can’t turn the radio on and off without the key being in, however if I press the menu button it brings that up.

Similarly, if I turn the car off with the radio still on, it doesn’t automatically go off like it should. I have to put the key in, turn the radio off, and then take the key out. (The centre display lights still stay on afterwards) 

Any ideas what this could be?!

I should also add that I noticed earlier on today (before noticing the above) that when I plugged my phone in via the USB port it didn’t charge up at all, and didn’t seem to recognise that I had plugged it in.

Try unplugging the bluetooth module (or remove the fuse for it). They can sometimes be known to keep the ecu "alive" and eventually drain the battery.

I disconnected the battery last night so it didn’t drain, ready to take it to the garage today. Connected it back up this morning and it’s working like normal! Very strange. Will bare the bluetooth module in mind, thanks!

Removing the battery will have done the same thing as taking the fuses out. You've essentially done the master reset I described above.
