Lincoln Corsair: Electric Powertrain Control / Description and Operation - Electric Powertrain Control - Overview
Overview
The center of the electric motor control system is a microprocessor called the Inverter System Controller (ISC), also known as the SOBDMC . The Inverter System Controller (ISC) receives inputs from sensors and other electronic components. Based on information received and programmed into its memory, the Inverter System Controller (ISC) generates output signals to control various relays, solenoids, and actuators.
The Inverter System Controller (ISC) can only power-up if an external signal is received from the BCM , the BCMC the DCDC , the BECM , the GWM or the ECM . There are three circuits that will wake up the Inverter System Controller (ISC): ISP-R from the BCMC , wake-up circuit from the BCM and the HEV Wake-up circuit from other HEV unique modules. The Inverter System Controller (ISC) will not be able to wake if the Vehicle Battery Power (VBPWR) circuit from the 12V battery is not connected to the module and the module ground wire(s) are not connected. Applying any of the 3 wake signals will cause the Inverter System Controller (ISC) to close the power relay integral to the BCMC VPWR circuits which supply main 12V power to the Inverter System Controller (ISC) and several other components.
Once the Inverter System Controller (ISC) is awake, it can sustain its own 12V power through a relay. The Inverter System Controller (ISC) can operate for several minutes after vehicle ignition key is turned off in order to perform various system functions. The Inverter System Controller (ISC) can be woken up and operate during High Voltage battery charging on Plug-in HEV to control the HVAC system to cool the High Voltage Battery.
Some failure modes require a complete power-down and restart of the Inverter System Controller (ISC) to recover. To ensure a complete module power-down, you must wait several minutes after key-off, or monitor the Inverter System Controller (ISC) communication to determine if the module has completely shut down.

Information on P Type Tires
P215/65R15 95H is an example of a tire size, load index and speed rating. The definitions of these items are listed below. (Note that the tire size, load index and speed rating for your vehicle may be different from this example.)
P: Indicates a tire, designated by the Tire and Rim Association, that may be used for service on cars, sport utility vehicles, minivans and light trucks. Note: If your tire size does not begin with a letter this may mean it is designated by either the European Tire and Rim Technical Organization or the Japan Tire Manufacturing Association. 215: Indicates the nominal width of the tire in millimeters from sidewall edge to sidewall edge. In general, the larger the number, the wider the tire. 65: Indicates the aspect ratio which gives the tire's ratio of height to width. R: Indicates a radial type tire. 15: Indicates the wheel or rim diameter in inches. If you change your wheel size, you will have to purchase new tires to match the new wheel diameter. 95: Indicates the tire's load index. It is an index that relates to how much weight a tire can carry. You may find this information in your owner’s manual. If not, contact a local tire dealer.
