How to clear engine management light

[WDZ]

Mas Spyder 4.2 2004
I had a P0491/2 codes showing...nothing major - I have cleared the alarms but engine management light is still showing
How do I clear this ?
Thanks guys

Did you clear them with the ignition on and engine switched off? Turn the ignition off and then turn on engine it should clear the CEL.

If not try again usually works second time
