Cadillac Repair: check engine light, info button, reset button

Question
my check engine light has come on again after several months. a local mechanic was able to turn it off by a series of steps pushing the dash buttons on my 2003 cad deville, i can get the codes to read on the instument panel but I just dont know the sequence of steps on pushing the info button and reset button at the same time thank you

Answer
Simultaneously push and hold the OFF and WARMER buttons for 3 seconds and then release them. The codes will appear and will stop.

As each code appears the word CURRENT or HISTORY will appear with each code.

I need to know what codes you get and if it is CURRENT or HISTORY.
