Basically my ecu/car is driving me nuts. When I bought it, it had been sitting without a battery for a good year or so. I fixed it up, put a new battery in, and everything drove great. However, I'm having the hardest time passing SMOG due to the fact that i keep getting CEL/MIL failure on the test. It states that it cannot complete all "internal tests, blah blah."
I took it to mechanic shop and had them run a readiness test to see which monitors/tests mine had passed and which ones had not.
Readiness Test Results
Misfire status = Complete
Fuel Status = Complete
Comprehensive Status = Complete
Catalyst Status = Not Complete
Heated Catalyst Status = N/A
Evaporative Status = Complete
Secondary Air Status = N/A
AC Status = N/A
Oxygen Status = Not Complete
Oxygen Heater Status = Not Complete
EGR Status = Not Complete
Now, I've driven my car a good 600 miles or so since the rebuild. I think that would've been long enough for all monitors to pass. I have no CEL codes or any issues with the car AT ALL. The only thing that's missing from the car is the AC condenser, so the AC does not work.
I don't see how having no AC would cause it to not clear all monitors but at this point, I'm pretty tired of this and just want a resolution. I've researched online and spoke to a mechanic who confirms that Nissan had some problems with early model OBD2 ecu's (96-97). Stating that their drive cycles where very annoying to get all the monitors to pass. I've even tried calling a dealership to see if they'd put it on a dynometer to run it through the drive cycle, but they stated they don't do that
Ugh, I'm at a loss, and I need this to pass in order to reg my lovely new vehicle.
PS - I've ordered an OBD2 plug-in which connects to USB on my Sony VAIO laptop. I ordered it from AutoEnginuity so it comes with some pretty quality software. Hoping that will help me solve some problems. Any help would be great guys, thanks.
EDIT - Also I meant 4 out of 8 monitors on thread title
