Circuit Description

The Reduced Power lamp (RPL) should be "ON" (only 3 seconds) steady with the ignition "ON" and the engine stopped. Ignition feed voltage is supplied to the RPL bulb through the meter fuse. The Engine Control Module (ECM) turns the RPL "ON" by grounding the RPL driver circuit.

The RPL should not remain "ON" with the engine running and no DTC(s) set. A steady RPL with the engine running and no DTC(s) suggests a short to ground in the RPL driver circuit.
