  3. Vehicle Start Feature Function Allocation to Subsystem

  4. Vehicle Start Feature Charger Contactor Status – Reported state of the HV charger contactors Command Type Of Start - Command for Silent Start Preconditioning, Silent Start Auto Stop, or Engine On Request Contactor Status – Reported state of the main HV battery contactors Crank Abort Request – Request to cease engine rotation prior to engine start. Engine Coolant Temperature – Reported temperature of the combustion engine oil Engine On Request - Indication that conditions have been met to start internal combustion engine rotation. Engine Producing Torque Status – Indication of the torque produced by the internal combustion engine Force AutoStop/Start Command – Command to perform an Auto Start or an AutoStop via a service/diagnostic tool. High Voltage Propulsion Charging Unavailable – Indication that the vehicle’s high voltage generator function is unavailable. Hood Status- Hood open or closed state HV Battery Data – Information regarding status of the high voltage battery, including in particular High Voltage Battery Minimum Temperature, High Voltage Battery Minimum Temperature Validity , High Voltage Battery Voltage Lower Limit Crank and High Voltage Battery Voltage Lower Limit Crank Validity. OBD Compliant Outside Air Temperature – OBD compliant determination of ambient outside air temperature Plug In Status – Information indicating whether the plug-in charging feature is active. Powertrain Diagnostics – Communication of the presence or absence of fault(s) within the powertrain subsystem. Propulsion System Active – Determination that the vehicle is capable of being propelled. PT Crank Active – Indication that powertrain is in the process of starting the internal combustion engine. Remote Start Request – Customer request to start the vehicle intiated by use of the key fob Transmission Oil Temperature – Reported temperature of the transmission oil Valid Vehicle Start Request – Indication from powertrain that engine crank has been initiated. Vehicle Refueled - Data describing whether the vehicle has been refueled. Vehicle Power Mode - An indication of vehicle electrical moding related to ignition switch position. Typical values are Off, Accessory, Run, and Crank. Program Signal Definitions
