Im at a loss. I took my car which runs great to the Inspection station. They had to cancel it out due to the port not reading {OBDII}. So I did the sesible thing and checked every fuse I could find under the dash and under the hood. Pulled each one out and visually checked them. I also reseated all the relays which allowed me to reset all my radio stations and clock Razz This is an ES Model. With No cruise control. There are no after Market accy's. Factory stereo, everything works and car runs fine. No lights out. No check engine light. Only thing not operating is the cigarette lighter which was broke when I bought the car. I installed an aftermarket accy port by using professional clips to tie into the factory lighter hot wire which was hot and grounded it to the frame. Any idea's? I hope I provided enough information. Many thanks! -Steve

HI
Most likely a wiring fault from DLC to PCM. Find Data Link Connector lower left dash and Then PCM behind glove box. Check with OHM meter for continuity from Green/ White at DLC to PCM terminal 113.
Check Orange wire at DLC to PCM term. 85
Check Light Green wire at DLC to PCM term. 84
Let me know
Thanks for donate

Turns out the connection was in fact loose in the area you recommended me to check. I secure the connection. Took it to Auto Zone and it gave a pass signal. I went straight to get the out of date by two day inspection lol to a local place. It failed.... Why? Because upon removing all of the fuses and relays to check them out visually, it was the same as disconnecting the battery. So it read [not ready] I did as was instructed and drove it 40 miles.. 48 to be exact and went back to see if it was reset and would pass. It did so beautifully. So your tip helped fix the problem, my goof reset the system. I passed that along for a foot note for anyone else who might read this. It is recommended you drive your car 40-50 miles before attempting to have the codes read after removing the battery/jumpstart etc... Also that was all I had in my Paypal. I will donate more than .43 cents as soon as my transfer is complete! haha Thanks for your efforts! saved me alot! -Steve
