I bought vitz 3rd gen 1.0 krfe.
Went to shop to install fog lights.
It already has wiring and button for fog lights.
but when hrhe installed lights the dont turn on.
then after series of fail attempt he installed his own wiring till fusefuse box below glove box andconnect it to rest of original company fitted wiring. Then lights start working perfectly.

Now after installation I started car. And check engine light, abs light and break light appear.
On scsscanning following errors apper

1. Open or short Rear right speed sensor.
2. Open or short RH sensor circicircuit
3. Ambiant temp sensor.

My vtz is right hand drive and japan made

You need to investigate the problems with the faulting circuits, if the fog lights were only a plug in to existing wiring, there should not be a connection to the failed circuits, if he has re wired to get the fogs working, you will need to ensure that the wiring has been done correctly and that the new wiring has not compromised the failed circuits.

Is it possible that the problem has occured due to old wiring.
Althoug now I went to the electrition asked him to remove fog light wiring and plug each n every wire in its place.

But problem is not solved uptill now.

Thanks for your reply.

I doubt that is the case, as the circuits are not connected to each other, you may have a damaged loom but I would be looking at live data first to see if there is any signal from the sensors first.
