Reduced Power Lamp
Reduced Power LampThe reduced power lamp (RPL) turns on when the ignition key is moved to the ON position. It should turn off in approximately 3 seconds or immediately after the engine starts.
If the RPL turns on during vehicle operation, a vehicle system failure resulting in reduced engine output is indicated.
If both the reduced RPL and the check engine light turn on, a serious problem affecting vehicle performance is indicated. Refer to On-Board Diagnostic (OBD II) System Check and RPL "ON" Steady, See Computers/Testing.
