9620 Professional OBD II Scan Tool

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.
