Diahatsu interior light - 2003 Daihatsu YRV

to replace corroded fluid lines

two options
find a diahatsu truck wrecker or junk yard
scavenge all the hard lines you need off.. the same model truck

have the hard lines made up from new pipe and connections
brake shop can do all the brake pipes ..even fuel pipes

anything odd a mobile hydraulic hose repair service

I am taking a bit of a guess because I don't have information on such a late vehicle but I think it is a fair bet Diahatsu are using embedded transponder chips in the keys with a steering lock/ignition switch mounted receiver.

That was a popular trend among manufacturers and was the system employed by Diahatsu in their earlier models with a master key and up to three slave keys. They are more likely I think to leave the basic system as it is and just add a remote locking system than to develop an entiely new system at unnecessarily high cost.
They could have cribbed a system from another manufacturer of course...

The Ford PAT system was just about identical and gave little trouble and they bridged the gap by fitting remote locking and providing a remote.
The Renault system was similar but many models were very troublesome as they aged and the immobiliser was soon updated and was integrated with the key "plip"

Both these manufacturers use a dashboard mounted light to indicate whether the immobiliser had been successfully disengaged but I have no information about the Diahatsu other than a note dedicated diagnostic equipment is required for key coding.
I am sorry this hasn't been much help.

May be coil pack or plug

Mine turns out to be lambda sensor...

Why did you ask us then?? :<)

You have to have the codes checked and repost. There are probably a 100 different things that will make the light come on

as diahatsu is owned by toyota,look at comparable parts.....
