Disconnect battery or not?

Featured Replies

If I want to remove the instrument cluster from a 2010 (Mk 2.5) Ford Focus, can I just pull out the connector from the back of the cluster or should I disconnect the battery first?

I don't have the codes for the radio at hand so would rather not disconnect the battery if I don't have to

Thanks for any replies

I've unplugged mine before and even drove the car out of the driveway with the cluster removed; but it only drives in limp mode with it removed,

Also there is a risk of shorting out electrics and damaging something; 

The headunit code should be inside the manual for the headunit a sticker on the front page, alternatively before you disconnect the battery or do anything;

Start the engine and switch off the radio 

Keep buttons "1" & "6" pressed at the same time; the headunit will then display different information including the serial number, if you use your phone to video it will save you writing anything down, 

You will need the serial number to obtain the code after disconnecting the battery; the only other way of obtaining the serial number is to physically remove the headunit.

Thanks @Lenny

That's useful information I did not know

I do have my radio codes but they are buried deep in my parent's garage and I won't be visiting them for a couple of weeks

I may have to risk unplugging the cluster with the battery still connected as 2 weeks without the radio means I will have to listen to the wife's moaning on every trip

Thanks again
