Not enough info.

How about the year of your car? Have you done any mods to do with the fans? What was the DTC #?

It's a 95. I have done the homemade manual fan switch mod. I tapped into the relay in the underhood box. I did that mod a long time ago though.

When was the last time you checked for codes? It could be an old code because the cooling fan relay control circuit code (assuming you got DTC 77) does not light the SES.

Was checked about 2 months ago.

Does the code come right back if you clear it?

Since you have modified the fan wiring and can override the automatic fan operation, you have to expect that you might get a DTC from it.

Yea, I just want to be sure that's all it's from.

I haven't cleared it yet.
