Cellar car issue - Page 2

Dagnabbit!!

This page explains how to get to the ECU to check the OBD, but instead of two screws,

there appear to be two plastic rivets... no phillips slots in them like the picture suggests and they can't be pried loose after five minutes of trying.

That doesn't seem right. They use the OBD for state inspection, for god's sake, disassembly isn't practical. You shouldn't have to go to the ECU, there should be a connector easily available to mechanic and inspectors???

Undertoad · 01-21-2010, 02:06 PM

Yah there's a connector, but I don't have the tool to read it. This is the back door method for people who don't have the OBD tool.

xoxoxoBruce · 01-21-2010, 02:10 PM

Oh OK, They don't give you a way to read the codes without a code reader? Pep boys should read the codes out for free, or so I'm told.

Take it to a shop with the proper diagnostic equipment, and let them figger it out it will cost less in the long run. I am a trained mechanic and I know this from experience.

Oh, you're no fun.

I'll go along with this. Temperature changes are a drag on car start ups. I put a half bottle of heet in my tank about every 3rd fillup during the winter months.

If it does it again... a half gallon of gas over the seats and a stick match will work very well.

No no, It's check insurance policy, a half gallon of gas over the seats, and a stick match.

He said it wasn't cold enough to freeze but still could be water.

Nissan has all the codes the same way. They are a series of short/long flashes with each representing a number - then you can look up the code.
I'd still take a look at the cap - it only takes about 5-10 minutes.

xoxoxoBruce · 01-21-2010, 03:12 PM

How does Nissan activate the flashing?

Correction - looks like it's an OBD-2, my bad.

classicman · 01-21-2010, 03:21 PM

Thats looks just like my old car Tony, it is right behind there and there is a slot for a phillips head screwdriver to start the OBD computer. I don't recall it being a difficult thing to access.

Oh wait - are those the plastic push screws holding that panel in? I still have a few of them - never could get them back in.

glatt · 01-21-2010, 03:25 PM

Maybe the previous owner had trouble getting them back in too, and glued them in.

xoxoxoBruce · 01-21-2010, 03:41 PM

Two types, one with a center pin that can be pulled with pliers so the button can be pried out, and the second kind that gets destroyed taking them out. Fortunately they are cheap(less than a buck), and most auto parts stores have a selection.

fuel pump? filter? carburetor?

ah I dunno

Did you check your 710 cap?
