Hey guys i recently picked up a 95 Nissan Maxima GLE. I love the car but im getting terrible gas mileage and then the other day my check engine light came on. I did the self diagnostic test with the ECU and it had 5 short pulses and 5 long ones which in the ECU decoder said "No Failure Recorded/Detected" So does this mean nothing is wrong with my car? If so why did the engine light come on? Im confused.

 

try to reset your ecu by disconnecting the negative battery terminal for about an hour. If you're not throwing any codes, that should hopefully knock out the check engine light. If it comes back try an odbII tester, not the one that come built into the ecu.

How could you not see that sticky?

 

WTF? can you not read? I read that sticky and even did the ECU self test. What i wanted to know was what the code i got back meant. I got back "No failure Recorded/Detected" and was wondering if that means everything is ok. And if so why did the check engine light come on in the first place. Why dont you read the whole post before acting like a tool

 

What part of NO FAILURE DETECTED can you not understand? Reset it and wait for a code to comeback(if one will)

 

I understand that. Listen to me once again....if there is nothing detected as wrong then WHY WOULD THE LIGHT HAVE COME ON IN THE FIRST PLACE? This is what i want to know. Is this just a nissan thing? Im wondering what could have tripped the engine light but then say nothing is wrong.

 

Ooh ooh! I know this one! I have done it this month. What I did to replicate this is since the ecu is so F*ing annoying to twist the screw, i dont know if its twisting or not, so I ended up resetting it instead of doing the first diagnostic part. Then I twist it again, look up, and its blinking 0505. This means that it was reset, so no codes...
