I keep getting an ERR on my OBD II reader. I believe I may have blown a fuse in the system. Can anyone tell me if the OBD II connection has a fuse link and where can I find it?
I've looked in the fuse box but there is nothing that is identified as an OBD fuse. Maybe it's inline or under the hood? I've checked the wiring and it appears to be good.
Ot runs, I'm just trying to check a CEL.

Make sure to have a compatible reader for the millenia.
Should be SAE J1850 PWM compatible.
That is the protocol to use.
If it has that protocol, and you get error, then yeah something
wrong with ecu. Try to reset the computer. Disconnect the neg. battery
cable for 10 secs, but just make it 30 secs, and then reconnect,
and get in drivers seat and pump brake pedal 5 times, OR for 10 to
15 secs. The computer should clear. The problem here is that it
will give you a p1000 which is an incomplete diagnostic. If the car
runs fine, and its not a problem for any reason(registration, or
operability), then you can take it down the road for 30-45 min. and
rediagnose the engine after completely resetting it.
I would reset it, and then see if the error code comes. In that order.
Then drive it on the highway for 30-45 min to get it to diagnose again.
They say you have to drive it like you would on a highway to get it
to diagnose correctly. 60mph should do it.
1. Get correct reader.
2. If you still get error, reset computer.
3. After reset, check again if error comes.
4. If error after reset, you got problem with ecu most likely.(do not go on to #5).
5. If error clears, drive car on highway for time, may take longer or shorter.
6. Check with code reader again.
7. Pull codes.
If you have the anti-theft sound system dont reset computer more than
3 times, and read the manual on how to reset the radio head unit.
If anti-theft light is on, then its activated(will fault). If light
isnt flashing then its deactivated, and no worry.
3 times faulted circuit, and BLAM, radio out. Will have to be reset.
Instructions are on this site, but who knows if it works.
