Service engine light

[kmoving]

Just wanted to let people know about the light.

Mine kept coming on, I checked everything, even took stuff apart, cleaned and replaced.

Still the light kept coming on.

I brought hame a (StayIce) for those of you that dont know what that is,
it's a unit that the military uses to check electrical and mechanical problems. Anyone that has been in a motor pool at Depot level will know what I am talking about.

Nice unit, about $11,000.00.

Found no probs with my Xterra, so I took the LED out for the service engine soon slot.

I did however replace it with another bypassing the ECG unit,

No more problems.

In the process I removed some other items that were usless, the Xterra breathes much esier now.

That just doesn't strike me as wise...

What other items you feel are useless? Better hope you know what your doing.

[kmoving]

I am by no means an expert.
But I have been building engines for some time.

I have come up with no other explanation (after thorough investigating)
for the light to be on except for a short, I did not want to trace every wire to find it, so like I said, I took the LED out and bypassed it with another, and have had no other probs.

And yes the new light still lets me see trouble codes.

Did you ever read the code with an OBD II reader?

[rav4t]

How do you remove the lLED?

[kmoving]

Yes I do have an OBD II reader, I had connected it several times over the course of a week , with no codes reading incorrectly, I even took it into the Nissan dealership I bought it from, they could not tell me anythind either, except that it was prob a short.

I still connect it (OBD II) from time to time with the same results, NOTHING.

so out it went.

I am reasonable sure that if there is a problem, I will notice it when it starts.

Is there a way to check the codes by using the key?

Example: On my previous car (Dodge Ramcharger), you can check the codes by turning the key on and of three times within 3 to 5 seconds (without starting the eng). The light would blink a number of times and reveal the code.

Does the Xterra have something similar? Trying to find it

[OffroadX]

No, but the 2000 models have a small screw on the side of the ECU itself that is turned to get the light to flash out the codes. Only the 2000 models have it.
