I have KIA CERATO EX car. When running The Speedo meter works for 8 or 9 km and stop working. When you start running in the next day it works and again stops after 8-9 km. What could be the problem

Your car is more of a wheeled computer than a conventional car so troubleshooting electrics is limited to fuses and visual inspection and a few basic tests at the lamps - unless a wiring diagram is available.

It is normal practice of many manufacturers to fuse the left and right parking light separately with one side also supplying the dashlights and the other side supplying the number plate lamp so perhaps a fuse has failed. Fuse details will be found in the original vehicle handbook.
Perhaps the hazard lights fuse has also failed but if it hasn't, again a wiring diagram will be needed...

Not sure what to say about the speedo as in theory that circuit is supplied differently, via an ignition circuit. Could be some dealer level diagnostic equipment will be needed to sort that one...

My personal suggestion would be to go for these repair catalogs. I know this website www.reliable-store.com that i used to get manuals from, and they have all models online.
I also brought for my 1989 BMW, such old model, they had it
and it was very good manual. Go ahead, I bet.

Look at the head light switch. That's all that's left in the circuit

Vehicle speed sensor or vss.

must be an internal gear problem take to a KIA dealer as they will probably know of a fault
