Checking the ECU Codes

I want to check the ECU codes for my 95 Maxima. While reading the stickies I saw directions to take off the cover from the self test module. But on my car there the plastic cover is held on with plastic screws without screw tops. Is there a special tool needed to take the cover off? Can I buy it at a local auto parts store? What kind of tools do I need once the cover is off?

Also, would it be more worth it to go and buy a diagnostic tool?

Thanks

Buy the code reader - Actron readers can be had for less than $50 on ebay. Worth it just in time it takes you take off the covers.

Just pry of those plastic clips. Then all you need is a philips screwdriver.

How do I pry the plastic clips off? I want to do it without breaking anything.

Or you could head to Autozone and ask to borrow their code reader for free.

Its very simple. I have a 95 SE and all you need is a flat head and phillips screw driver. Use the phillips to gently unscrew (about a 1/4 turn) the 2 plastic screws.

Pull the screws out by hand and then pull the plastic inserts out. The panel should fall off exposing the ECU.

Then gently insert the flat head driver into the screw on the ECU gently breaking through the plastic covering.

The rest is explained in detail on the ECU code sticky.

Hope this helps.

I used a small pair of scissors. I pried under the plug untill both sides were under and just yanked the crap out of it.

Worked like a charm.

You won't break anything.

I fully recommend using the CORRECT size screwdriver.. its a small screw in there.. you don't want to miss the screw and contact the ECU inside as I did.. nice sparks though Ideally you should use a plastic tuner fork thing.. looks like a screw driver but it has a plastic tip

The screw you are turning inside the ECU is not really a screw, its Potentiometer which is a little electric component with a plastic screw type fitting on the front.. so be VERY gentle with turning and STOP at the stops.
