Failure Mode Effects Management (FMEM) (Code 98)
WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 1988 Ford Ranger, 1988 Ford RV Cutaway, 1988 Ford Pickup, 1988 Ford F-Super Duty, and 1988 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
The FMEM mode allows system operation when one or more sensors fail or transmit signals which are out of their normal operating range. The ECA will substitute a mid-range signal for the defective sensor and continue to monitor the sensor. If the faulty sensor signals return to within the normal operating range the ECA will use those signals. A code 98 will be displayed when the FMEM mode is in effect.
