Circuit Description

Reduced Power Lamp (RPL) should be illuminated whenever ignition is turned on, engine not running position. Ignition voltage is supplied to RPL indicator bulb through the C-10 METER GAUGE fuse located in dash fuse box. PCM illuminates RPL by grounding the RPL driver. RPL should not remain illuminated when engine is running and no DTCs are stored. A steady RPL with engine running and no DTCs stored suggests a short to ground in RPL driver circuit.
