TM   9-2320-360-20-3 Section  5 DIAGNOSTIC   DATA   READER   INFORMATION   (Cont’d) 4.  ENGINE  DATA  LIST The Engine Data List menu selection displays the set of DDEC III data parameters that pertain to the operation of the engine and  vehicle. NOTES: (1) Engine data list parameter values that are displayed as ‘N/A’ (not available) typically indicate that the sensor(s) and/or function  is  not  part  of  the  engine  configuration,  or  the  parameter  data  is  not  being  transmitted  by  the  DDEC  III  ECM. (2) Engine sensor parameter values that are displayed as ‘FAIL’ is an indication that a FMI 3 (Sensor Voltage High) or a FMI 4 (Sensor  Voltage  Low)  diagnostic  condition  is  currently  active  for  that  sensor(s). Parameter  (11):  ACTIVE   CODES Definition: Indicates  the  presence  of  a  condition(s)  that  causes  the  check  engine  light  to  be  on. Typical Range: YES or NO Parameter [2]: INACTIVE  CODES Definition: Indication  that  past  active  codes  have  been  stored  in  the  ECM  memory. Typical Range: YES or NO Parameter [3]: ENGINE  RPM Definition: Indicates  engine  RPM  as  determined  by  the  Timing  Reference  Sensor  (TRS). Typical Range: 0 to 2500 RPM Parameter [4]: PULSEWIDTH Definition: Fuel Pulse Width - Number of degrees crankshaft rotation that the EUl’s control valve is closed and fuel is entering  the  cylinder Typical Range: 0.0 to 25.5 Degrees Parameter [5]:  BOOST Definition: Boost Pressure - Pressure of air measured by the Turbo Boost Sensor (TBS) downstream on the compressor  discharge  side  of  the  turbocharger. Typical  Range:    (0.0 to 43.5 PSI) or (0 to 305 KPa) Parameter [6]: TPS  CNTS Definition: Throttle Position Sensor (TPS) Counts (CNTS). Indicates the analog to digital (A/D) conversion of (0 to 5 volts)  from  the  TPS  to  (0  to  1024  counts)  that  the  ECM  uses  to  compute  the  percent  throttle  opening. Typical Range: (0 to 1024 Counts) or N/A Parameter [7]: TPS  PCT Definition: Indicates  the  percent  opening  of  the  Throttle  Position  Sensor  (TPS). Typical Range: 0 to 100% Parameter [8]: VSG  CNTS Definition: Variable  Speed  Governor  (VSG)  -A/D  Counts.  Indicates  the  analog  to  digital  (A/D)  conversion  of  (0  to  5 volts)  from  the  VSG  to  (0  to  1024  counts)  that  the  ECM  uses  to  compute  the  VSG  set  RPM. Typical Range: (0 to 1024 Counts) or N/A H -259
