I I recently purchased a 2000 Nissan Altima and discovered when I had to smog check it that the check engine light does not work. It does not come on when you turn the key on, automatic fail. I want to check the wiring pin to pin but the Chilton manual is not specific enough. Any ideas.
Took out instrument cluster and checked them with a meter. Can see scratches where someone else has checked them before. Also have continuity between the light socket and several pins at the instrument cluster socket.
True. You could have just took out the neighboring warning light (bulb) next to it, and swapped it into the check engine light spot and see if it illuminated lol, surest and easiest way to see if its truely a bulb issue or not. I would still try and do that.
If still nothing, it might be a contact issue, or you might have to start chasing wires and wiring diagrams. Maybe jserrano will have some input for you as well.

No voltage at the bulb. Found a recent wrecked 2000 Altima on craigslist. Got the computer for $80.00. Light works now.
Just a note: since 2000, the ECU has to be programmed to the ignition keys in order for NATS to work. Otherwise, the engine will have problems starting up. Just beware of this if you should have starting issues.
Check engine light does now work but car still fails for OBD EVAP, OXY SNSR, and OBD EXHST GAS. All 3 fail for not compleat. I assume it is because the the ECU was unpluged and lost its memory. How long does it take to compleat these. IE drive time / start stops. Do I need do do any thing specific to program the ECU to the car?
