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
