Default After Jumpstart - Lost my instrument panel LCD

Hi, the other day, after jump starting my 2006 CL Focus I noticed that my LCD display (odo, trip meter, temp etc.) went blank.

I've jump started the car before without troubles, does anyone have any idea what's gone wrong? My mechanic doesn't. Could I have fried a fuse somewhere? It's worrying me.

Cheers

Fairly sure the ECU in most modern cars don't like being jumped started...

maybe you got lucky the first couple of times but this time I'm not so sure...

oh no. Are they expensive? I've never heard of this new no jumpstart rule. I see cars being jumpstarted everywhere.

Have a look at the above mentioned page and make sure you had the jumper cables set up as per the image, otherwise theres risk damaging the ECU as rand0mn00b mentioned im sorry to say :/

generally speaking... yes. the ECU = electronic control unit. basically your car's central computer. I believe it is generally an expensive and difficult procedure. maybe it's something simple though, such as a fuse or something in the instrument cluster, though that's generally an expensive fix too... might be worth getting an auto electrician to check it out

maybe older cars are still being jump started, but you'll find as time goes on and as cars become more reliant on computers this will probably becomes less common

those manuals are for the US focus - which is slightly different to the Australian Focus which has more in common with the UK spec

I'm fairly sure the owners manual for our Focus doesn't have a section on jump starting and if it does it says specifically NOT to - I'll check tomorrow unless someone else has their's handy. Surprised the US focus is ok with it...

Disconnect the battery for a little while and reconnect it.

I'll have to find an auto electrician. How long should I disconnect the battery for - overnight or short, like 10 min?

Check your fuses too. May have blown one ;)

A few minutes should be sufficient.
