Does anyone know how to clear the codes in the history?

Simultaneously press and hold the OFF and WARMER buttons til all segments of the DIC light up as a segment check. The stored DTC's will be displayed on the bottom of the DIC. After that you will see "PCM?" Answer yes with the HI FAN button. Then answer no with the LOW FAN button to the next promts til you see "CLEAR PCM CODES?" Answer yes.

Or if you cant get that to work, you can go to your nearest Advance Auto Parts or Autozone and have them clear your codes with their hand scanner.

Or pull battery power.

If you pull the battery cable and let the computer reset, the car may run like crap for up to 30 miles. The computer will be reset totally and the car will go into re-learning all the perameters of the engine and compensate for any issues. It may be better to have the codes reset so the computer doesn't have to relearn and try to compansate for all the problems that may arrise.
