Hello to all,

Having a few electrical gremlins and asking for some help/ guidance.
I have a 2009 Kia ceed 1.6 crdi where all the gauges in the instrument cluster flash then resets, this is random when this happens and how many times it flash’s but not normally more than 6 times. But normally within the first 15 minutes of driving then settles down.

Also the horn is extremely intermittent, alot of the time the horn doesn’t work, then sometimes only part of the airbag area where you push for the horn will work then completely stop. It seems as these 2 issues are connected in some way?? Although when stationary the horn seems to work ? Confused 🤔

A new battery has been fitted to the vehicle but this has not rectified the issue.

I have checked behind the steering wheel cowls and removed lower part of dash and can’t see anything that’s loose/.
I have tried to remove the instrument cluster surround part seems unwilling to come away from the cluster. Trying to find a guide to remove it.
I have a 5 second video clip of the flashing, but unsure how to upload on here?

so many questions I do apologise

Many thanks Aaron

Hi & Welcome.

I would check battery terminals & that the earth strap to engine is in good condition & making a good connection.
Horns often fail so check the connections on the horn are clean.

Hi just an update and thank you for a quick reply 👍
I had previously checked and cleaned the battery earth straps ✅
But when checking earth strap I noticed a lot of corrosion on the 2 x earth straps that come from the ecu harness to body, cleaned the strap ends and fixings and voila ✅ no more flashing/ flickering dash lights. Very relieved.
I also ordered a new horn so hopefully that should be sorted also 👍
Thanks again

hi Jany
The first thing to do is disconnect battery sensor on the negative cable, then disconnect the battery cables (10mm spanner) (negative first then the positive)
Then check the 2 wires coming from the ecu
Automotive lighting Vehicle Automotive tire White Motor vehicle

Automotive tire Fluid Gas Automotive exterior Tints and shades

Once the cables have been removed from the battery, check the above 2 x earthing cables from the ecu harness to the car body. To remove these a 10mm ratchet spanner is required, the bottom fixing is a bit fiddly.
Once the cables have been removed the fixing (including thread) and the end of the cables (that connect to the body) need cleaning with a wire brush until all the corrosion has gone. Once these are clean just reassemble the cables back onto the body. Then When reconnecting battery, connect the positive first then the negative cable then the battery sensor into the negative cable connector. I hope this makes sense?


DO NOT disconnect any wires when the battery is connected to the vehicle.

Hi jany, yep that looks like the issue, give them a good clean with a wire before you attempt to remove them. Mine looked just like that, just go slowly working the bolt back and forth, you can use wd40 to penetrate any rust as long as the battery is disconnected 👍
