Actron KAL9620A - Manual (Page 29)

9620 Professional OBD II Scan Tool 29
CLR DST (0km-65,535km) or (0- 40,722miles)
Distance Since Cleared Diagnostic Codes is distance since diagnostic trouble codes
were erased.
CLR TIM (0 - 65535 min or 1092.25 hours)
Time Since Cleared Diagnostic Code is time since diagnostic trouble codes were erased.
CMD EQ RATxy (0 - 1.99)
Commanded Equivalence Ratio is the ratio of the air/fuel mixture.
NOTE: The CMD EQ RAT will read 1.0 while in a closed loop of fuel
COOLANT (-40 - 215°C)or(°F)
Engine Coolant Temperature displays engine coolant temperature from engine cool-
ant temperature or cylinder head temperature sensor.
NOTE: The coolant on many diesels may use Engine Oil Temperature instead.
EGR CMD (0 - 100%)
Commanded Exhaust Gas Recirculation is the percentage of exhaust gas being recir-
culated.
EGR ERR (-100 - 99.22%)
Exhaust Gas Recirculation Error will show the error from changing from one condition to
another.
ENG RUN (0 - 65,535sec.)
Time since Engine Start is the time the engine is running.
NOTE: ENG RUN stops when engine stalls or engine is turned off for any reason.
ENGINE (0 - 16383.75 RPM)
Engine Revolutions Per Minute (RPM) is the speed engine is running.
EQ RATxy
O2 Sensor Equivalence Ratio for Bank x Sensor y.
EVAP REQ (0-100%)
Commanded Evaporative Purge is the position evaporative purge control valve is open
in percentage.
EVAP VP (-8192PA - 8191PA) OR (-32.8878 - 32.8838 H2O)
Evaporative Emissions System Vapor Pressure is pressure in the fuel tank
FUEL LVL (0 - 100%)
Fuel Level Input is the percentage of fuel with 0% equaling tank is full and 100% when tank
is empty.
FUEL PRES (0 - 765kPa) or (0 - 110psi)
Fuel Rail Pressure is the fuel pressure at the engine in respect to atmospheric pres-
sure.
FUEL SYS (OPEN or CLSD)
Fuel System Status show loop status of fuel system banks.
OPEN: Computer module is operating in Open Loop control strategy. The vehicle has
not yet satisfied conditions for the computer module to go to closed loop.
CLSD: Computer module currently functioning in Closed loop control strategy, using
O2 sensor(s) as feedback for fuel control.
OPEN1: Open Loop control strategy is being used by the PCM due to driving conditions
– power enrichment and deceleration enrichment.
OPEN2: Computer module is operating in Open Loop control strategy due to detected
system fault. Certain actuator or sensor faults are usually the cause.
CLSD1: Closed Loop control is current storage being used by PCM, but a fault with at
least one O2 sensor has been detected. The control system may be using
single O2 for fuel control calculations.
