AA,
I have Toyota Passo 2010 procured 3 months ago, it doesn't have Catalytic Converter and therefore ECO mode light was off on all speeds although ECO mode was on. Yesterday I installed CAT and clear the ECO mode error through computer scanning, it worked fine below 90 KM speed and when I crossed 90 KM and came back to lower speed ECO light didn't get on and i think that there must be EFI or ECO mode error. Can some confirm what should I do.
