Using Hybrid Electronic Cluster (HEC)

To enter HEC self-diagnostics, press instrument cluster SELECT/RESET button before turning ignition switch to RUN position. Within 5-8 seconds, odometer will display "tESt" to begin self-diagnostic mode. SELECT/RESET button must be released within 3 seconds of odometer displaying "tESt". Repeatedly press SELECT/RESET button through odometer displays until dtc is displayed. When odometer displays "dtc", press SELECT/RESET button again and any continuous DTCs will be displayed before odometer advances to next display. Other HEC diagnostic modes can be entered when self-diagnostic function is entered. See HEC SELF-DIAGNOSTIC MODES  table.

All Segments Illuminated Illuminates all odometer segments. If any odometer segment is inoperative, replace instrument cluster.
bulb Illuminates all micro-controlled lamps and LEDs. Replace bulb or LED as necessary.
r Returns to normal operation all micro-controlled lamps and LEDs and displays hexadecimal values for ROM. If alternating flashes of FAIL and ROM level are displayed, replace instrument cluster.
