Running the Self-diagnosis Function'97 mod€l:
Turn the ignition switch ON {ll), then set the mode control dial to the Vent position, and the recirculation controt switch toRecirculate {recirculation indicator light comes on). Press and hold the recirculation control switch to Fresh (recirculation indi-cator light goes off). Continue to hold the switch; the recirculation indicator light will come on for two seconds. then it willblink the Diagnostic Trouble Code (DTC) to indicate a iaulty component. lf no DTC'S are found, the indicator liqht will notblink atter the initial two second light.
'98 - 00 models:
Set the mode control dial to the Vent position, and turn the ignition switch ON (ll). Within six seconds after turning the igni-tion switch on, press the recirculation control switch the required number of times depending on the recirculation indicatorlight status:
