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 circuit 1579. When grounded, the body control module (BCM) requests
the engine controller to perform an oil life reset. When reset is completed, the BCM
will turn OFF the CHANGE ENGINE OIL telltale.
