To check for Diagnostic Trouble Codes stored in the computer, turn the ignition on, then hold down the OFF and WARMER (for digital dash) or OFF and passenger-WARMER buttons (for analog dash) or OFF and "Info ^" buttons (if you have temperature dials) until all of the dash lights come on. The digital display will then show any codes stored. Be prepared to write them down. When it's done, you will probably see "PCM?" at this point use the fan speed up button to select pcm now it should say "PCM CODES" press the fan speed down button to scroll down to "CLEAR PCM CODES" press the fan speed up button and it should say "PCM CODES CLEAR" now turn off the ignition and your good to go.
