The CHANGE ENGINE OIL telltale is reset by depressing the oil life reset push-button
switch. This switch is located in the underhood junction block. Pressing this switch
grounds circuits 1579. When grounded for 3 seconds, the body control
module (BCM) requests the engine controller to perform an oil life reset. When the
reset is completed, the BCM will turn OFF the CHANGE ENGINE OIL telltale.
