Toyota Corolla L Touring 4wd

[twixsel]

Hi wondered if anyone has advise on the abs light that has illuminated and stayed on when driving my 1999 toyota corolla estate l touring estate 4wd import. also there is another warning light that appears and the dahboard and came on at the same time but have no idea what it symbolises. Both front tyres are pretty worn and I will be replacing these this week and wonder if there is any connection with this and the warning lights. And would be helpfull if anyone knows of a good place for abs and warning light diagostics in the south east london area bearing in mind it is an import from japan.

thanks
