Keith Browning Posted April 18, 2018 Share Posted April 18, 2018 For some reason I have always hated the term "limp mode." I don't know about other manufacturers but I don't recall Ford ever using the term. But there are others that are a little more descriptive. FMEM - Failure Mode Effects Management - A powertrain control module default operating mode that that allows the engine or transmission to function with limited capacity during a major system malfunction. Engine Derate - A torque reducing feature intended to minimize or prevent engine damage due to a system not functioning properly. Fail Safe - If you deplete the engine coolant supply, this feature allows you to temporarily drive your vehicle before you incur incremental component damage. Are there any more Ford terms to describe fault modes or operation? Quote Link to comment Share on other sites More sharing options...
