Lincoln Corsair: Rear Electric Drive Assembly / Description and Operation - Rear Electric Drive Assembly - Overview
Overview
The center of the electric motor control system is a microprocessor called the Secondary Inverter System Controller (S-ISC), also known as the SOBDMB . The Secondary Inverter System Controller (S-ISC) receives inputs from sensors and other electronic components. Based on information received and programmed into its memory, the Secondary Inverter System Controller (S-ISC) generates output signals to control the secondary electric drive (electric All Wheel Drive) and the auxiliary cooling pump.
The Secondary Inverter System Controller (S-ISC) can only power-up if the primary ISC powers-up and closes its power-sustain relay (PSR).
Some failure modes require a complete power-down and restart of the Secondary Inverter System Controller (S-ISC) to recover. To ensure a complete module power-down, you must wait several minutes after key-off, or monitor the Secondary Inverter System Controller (S-ISC) communication to determine if the module has completely shut down.
DTC s referring to the "generator" were used for the Secondary ISC. The primary ISC operates both a motor and a different generator. These electric machines operate largely in the same manner despite the different naming convention.
