Self-diagnosis Function
The heater control panel has a self-diagnosis function.
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:
.lftheindicatorlightisON,presstherecirculationcontrol switch five times..lftheindicatorlightisOFF,presstherecirculationcontrol switch six I|mes.The recirculation indicator light will come on for two seconds, then blink the Diagnostic Trouble Code (DTC) to indicate afaulty component. lf no DTC'S are found, the indicator light will not blink after the initial two second liqht.
