I don't think the PCM has a fuse. But to reset the SES light, disconnect the battery.

On a 1994, look for the PCM BATT fuse in the fuse panel on the left side of the dash.

As Shoebox mentioned above, but when are you looking at the fuses itself. It's the bottom left hand corner fuse. I think it's the blue 15 amp fuse.

The car will not start with it out. Just pulling the fuse does the reset. Give it about 10 seconds and put it back in.

I usually just take out the fuse for about 2 mins with NO key in the ignition. I tried 30 & 45 seconds, but it didn't fully reset the PCM, I still had trouble codes.

Hmmmmm..... #4, upper right corner, red 10A. Are the Z's and the Pontiac's different in 94? Did they flip the panel over?

PS: How did we know he was asking about a 94?

As it turns out, the fuse boxes between the Camaro and Firebird are flipped 180º . The fuses are numbered the same, but one is upside down from the other. Strange, eh?

I looked at his website for the car info. I guess it was easier than asking. <shrug>

Very strange......

I'm at the point where I'm not even going to bother with questions that don't include a signature, with the basic info like year of the car

MHO is not directed solely at you, but here it is:

It does not take but a few characters to indicate"94Z M6" or whatever. The glory list can be saved for the web page if not directly pertaining to the post. The people that it irritates the most are probably the one that answer a lot of questions and want to provide an intelligent answer. Those are the people you want to respond to your posts.

Time is valuable to a lot of folks and having to jump to other web pages and maybe having to wait for them to load and then getting attacked by zillions of pop-up ads (not that yours does)...it can get aggravating.

The easier you make it for people to help you, the better it is for you.
