There are two reset procedures, one for the NVRAM and the other for the KAM. Neither will erase your radio presets and such like the method SpooledUp7 posted:

1) With the key in the off position, press and hold the odometer reset button and turn the key to on;
Continue to hold the odo button until the odometer reads "TEST" and then release.
2) Turn the key to off and repeat step one.

This will reset the entire PCM except the KAM which contains the sensor profiles amongst other things. You can reset it with the familiar procedure:

1) Turn the key to on
2) Depress the brake pedal rapidly 20 times in a row until the oil pressure gauge sweeps to halfway and back again.

Do the two resets - They'll take less than a minute...

Also, don't forget that your DSC light will be on after you re-connect the battery. Reset procedure is: ignition on, turn wheel full right (clockwise), full left (counterclockwise), shut off.
