Initial Inspection and Diagnostic Overview

1. Check to see if HORN-DM, INST-LPS or RADIO fuses are blown. If fuses are blown, locate and repair source of overload and replace fuses.
2. If fuses are not blown, proceed with diagnosis.
3. Turn park lamps on and panel dimmer control to HI. Observe panel illumination lamps. If lamps are not illuminated, go to LIGHTING SYSTEMS/INSTRUMENT PANEL ILLUMINATION for diagnosis.
