Service Engine Light

[orange1]

1999 4 cylinder. Just replaced catalytic convertor. Now I need to reset the service engine light how do you go about doing that, I tried taking off the battery cables and touching them and then starting the truck up but the light is still on.

Thanks Tony

you need an obdII scanner in order to delete the codes to turn off the check engine light. disconnecting the battery cable doesnt work anymore.

Thanks, I guess I'll have to go borrow my buddies scanner.
