Reduced Power Lamp

The 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 the OBD-II system check. No Reduced Power Lamp (RPL) and Reduced Power Lamp (RPL) "ON" Steady in this information.
