because it was dark, i couldn't see much and i thought that was the hole i needed to go through. i looked at the picture online but i didn't memorize the picture like i should've

 

You might need a new ECU if you messed yours up . They're not to expensive.

 

well if anything and my ECU is all @#$%ed up, can someone tell me how to remove it as i will plan to go to a junk yard, buy a used one and replace mine.

 

nobody knows how to remove the ECU?

 

Yup ... sure do ...

But that's on my '95 with OBD-I

 

just tell me, im sure it's not that different. what have a got a lose anyway haha

 

Remove both plastic things on both side that protect ecu. On the passengers side there is a wiring harness that you need to loosen with a 10mm socket, then there are 4 screws one on each corner of the ecu, unscrew those then slide the damn thing out
DISCLAIMER: I am not responsible for what you do

 

I wont tell you but I'll suggest you search ... Or get a haynes since it's cheaper than search

oh yea disconnect battery

 

thanks and after i replace it, there should be no programming necessarry right. the check engine light should light up along with everything else right? or do i have to do the clockwise screw again?

 

I didn't d/c mine when I got my JWT .. that must be why the rev limiter doesn't work .. Jeez, I was wondering why it would go past 7000

 

Well, he can't start his car...

 

You know, he's really concerned about his check engine light...What if the bulb is just burnt out????

 

Still can't start it

 

im about to head out to the junk yard and buy an ECU. now can i buy any year (95-99) or just my year ECU?

 

Wait, so you don't know what CEL is and tried to turn off your CEL light by poking in the wrong hole with a screw driver because you couldn't see 'cause it was dark, and don't know how to use a flash light, and also forgot what it looked like when you got to your car from your computer; and stuck it in there for about 3 minutes; and now your car won't start and also now trying to remove the ECU?? *whew*

Good luck. Don't blow up your car.

 

so can i put in an ECU off of any maxima of the 4th gen. or does it have to be only a 98?

 

Did you try checking the ecu power supply fuses? I believe they are # 57 & 58.

 

yeah i did, they all work

 

wow DPOTY DPOTY

 

Dumb Person Of The Year

 

how much does an ECU go for. i went to a junk yard and they want $150 for it. isn't that too much?

 

That sounds about right I think. Hard lesson learned I guess.

If you think it's too much go to a few other junk yards and see what they ask for it. Otherwise what choice do you have?

 

www.car-parts.com
will probably be your friend in this one..

 

thanks, there are 3 types though (6/97,7/97,3/98) which one will work on my '98 maxima se auto? do you know? do i have to check something in my car?

 

why don't you just change the bulb for the CEL light? just concern on the money part.

 

If you can't do a simple thing like turning a screw w/o messing anything up, what makes you certain you can replace an ECU? Not everything is based on book or technical knowledge....you also need to use common sense. Common sense to use a flash light when you know that you will be working on a sensitive piece of equipment such as an ECU, common sense to know that if the screw driver went in deep that you probably poked the wrong hole, and lastly common sense to know that this task is way beyond your ability. My suggestion, take your car or have it towed to an automotive electrical shop. Chances are you shorted your ECU and that will definitely be a costly one. Hope you learn your lesson from now on, taking shortcuts will only give you grief.

 

To pull the codes you should have turned the screw clockwise about 1/2 turn, paused 2 sec. and then turned back ccw until you hit the stop, about 1/2 turn. The screw turns very easily and you can feel the stops. Try going back to the clockwise stop and then backing off 1/2 turn the other way. I'm just guessin here but maybe you can find the run position. It's just a rotary switch in there that puts you in and out of test mode.

 

because my car won't start. it's not just the bulb

 

Is it just me or did he say his cel wasnt working but he checked codes anyway? so how would he know if the light it working when he tried it now?

ecu run about $100.

 

how costly?

 

dude, you haven't bought the ECU yet?

 

I'm a village idot. But my question is why can't Autozone or Advanced Auto Parts check for a CEL code on my '95 Max? Advanced Auto Parts told me they can't check CELs for cars that are older than '98. Autozone told me "you can only come here to have it checked on Sunday after 10am". I'm like WTF! Is it my understanding that there are two diff. scanners? But I'm really lost as to why Autozone can check it, but only on Sunday after 10am.

 

The general consensus seems to be that some 95's came with OBD1 systems and some have OBDII

 

They're idiots and think that all '95 and older cars are ODB-I while Nissan was a step ahead and also made the '95 Maximas ODB-II, therefore, tell them they certainly can check the codes since it's ODB-II just like a '96, '97, '98, whatever. They just don't know their maximas

And as for this ECU issue...you should NOT be messing with your car! Upon looking at the picture on your computer screen couldn't you at least see and REMEMBER that the screw is on the SURFACE of the ECU? In other words...you DON'T poke into a hole to get to the screw? Here's some advice...never try to work on your max ever again. This is just as bad as this guy I delt with the other day at the shop I work at who came back after I put his spare on telling me I put his wheel on backwards. I asked him what he was talking about...and he pointed and showed me and was like "see it's different than the other wheels." I tried not to laugh and was like "ummm, that's your spare I put on...it's not going to look like your other wheels...."
It confuses me how some people in this world can survive...

 

Yo man. 95MaxTampa is a DIFFERENT person.

 

I know he's a different person. If you read my post carefully you would have seen that the very first 2 sentences address his question about why Autozone or Advanced Auto Parts are telling him they can't check his codes since he has a '95. I just happened to make a comment towards your situation in the same response and it wasn't directed towards 95MaxTampa (which I thought was obvious since you're the one with the ECU prob). I will address you in a seperate post if that makes you happy

 

If YOU read the OTHER posts, you would see that euser95 is the one with the ECU issue, not me

 

My apologies then, I remember now but it is a little late at night. I wasn't thinking and assumed since you were being such a nit-picky b*tch about absolutely nothing that you must have been the one who started the thread. I'm sure 95MaxTampa would have been competent enough to be able to tell I wasn't directing the ECU comment towards him and instead had taken the time to answer his question while at the same time saving myself time and commenting on the overall issue of the thread in the same post. I'm not a post ***** and am not going to post more than necessary to answer questions or make a point. Would have been much easier for all of us to mind your own business
