What fuse or replay could cause the Check engine light to not come on when the key is on? I need to pass smog and without the check engine light coming on it is an automatic fail.

Passed smog 2 years ago all was fine car runs fine too. please help

There are just too many to list....
LED in cluster is bad most likely if everything else (DTCs, readiness, etc.) are all good.

Does and OBDII reader show if the CE light is on? That would tell me bulb/led.


CE light did not come on when Relay 109 failed on my OO but it also wouldn't start. Glow Plug light and CE did not illuminate, and no power to fuel shut off solenoid on FI pump, thus no start.
