Failure Mode Effects Management (FMEM), Code 98 Or 998

FMEM mode allows system operation when sensors fail or transmit signals that are out of normal operating range. During FMEM mode, ECA substitutes a mid-range signal for defective sensor while continuing to monitor sensor. If faulty sensor's signals return to normal operating range, ECA will use those signals. A Code 98 or 998 will be displayed when FMEM mode is in effect.
