"check engine soon" light

How do I reset the blasted "check engine soon" light on my 2001 L300 V6?

 

Take the vehicle to your local Autozone-ish place and see if they will
read the code from the computer for you. The SES light means that the
computer has stored a code which corresponds to something wrong. To get
the light to go off, solve the problem which is causing the code.

I heard on some other GM cars, cycling the key to on then off without
starting the motor for 8 times does the trick.
On some others, disconnecting the battery for a while does the trick as the
computer reboots when power is restored.
You might try these and see if one works.

 

yip take the red terminal off your battery for ~15 sec should work. Eiher
that or find the ECM (PCM) fuse (its in the underhood fuse box) its clearly
labelled and pull it out for ~15 secs. I'd go for the ECM fuse since you
have to reset your clock/radio settings etc etc with the battery option.
