Clear OBD-II Codes
Is there a way to manually clear the OBD-II codes on a '98 ranger? I disconnected the battery for about an hour but I've heard that only turns off the CEL which it did. I've repaired my problems so now I want to make sure no codes are still being stored.
Thanks

Pull the ECU fuse in the underhood relay box for 20 minutes and you'll get the same results....and keep radio presets. I'm spoiled that way.
If you fixed the problem, as noted, you won't have anything more to worry about.

I've disconnected the battery in the past and lost everything on the radio. I've done it twice in the past week and the presets are there but I have to reset the clock. Go figure. I think this truck has a mind of it's owns. I've had a strange problem for about 6 months where the passenger airbag off light stays on when the switch is in the on position but goes out when i turn it off. In this case the airbag light on the dash flashes code 25. When I turn the switch to on, the passenger switch light goes on and the dash light goes off. I disconnected the battery for about an hour the other night and now everything seems to work as advertised. Is there a difference in disconnecting the battery for 30 minutes as opposed to an hour as far as to what is reset?
