Usage

IDLE AIR VOL LEARN

The idle air volume that keeps the engine within the specified range is memorized in ECM.

When learning the idle air volume.

FUEL PRESSURE RELEASE

Crank a few times after engine stalls.

When releasing fuel pressure from fuel line.

TARGET IGN TIM ADJ*

Idle condition

When adjusting target ignition timing.

TARGET IDLE RPM ADJ*

Idle condition

When setting target idle speed.

SELF-LEARNING CONT

The coefficient of self-learning control mixture ratio returns to the original coefficient.

When clearing mixture ratio self-learning value.

G SENSOR CALIBRATION

• Park the vehicle on a flat road.
• Adjust pressure in all tires to the specified value.

Calibrates G sensor.

WASTEGATE ACTUATOR POSI LEARN VALUE CLEAR

Ignition switch is ON and Engine running

When learning full close position of wastegate actuator after ECM or turbocharger assembly is replaced.

ENGINE COOLANT BYPASS VALVE

Condition: The valve is in the full opening position

When filing with coolant.

A/F INITIAL LEARNING

Air fuel ratio learning frequency is low while idling, learning the air fuel ratio of the idling domain in ECM.

When learning the air fuel ratio.

VALVE TIMING OFFSET DATA WRITING

Ignition switch: ON (Engine stopped)

When adjusting valve timing offset angle after ECM or engine assembly is replaced.

VALVE TIMING OFFSET DATA CLEAR

Ignition switch: ON (Engine stopped)

When clear the valve timing offset angle data after replacing the camshaft or timing chain.

CLSD THL POS LEARN

Ignition on and engine stopped.

When learning the throttle valve closed position

EVAP SYSTEM CLOSE

Close the EVAP canister vent control valve in order to make EVAP system close under the following conditions.

• Ignition switch ON
• Engine not running
• Ambient temperature is above 0°C (32°F)
• No vacuum and no high pressure in EVAP system
• Fuel tank temperature is more than 0°C (32°F)
• Within 10 minutes after starting "EVAP SYSTEM CLOSE"
• When trying to execute "EVAP SYSTEM CLOSE" under the condition except above, CONSULT will discontinue it and display appropriate instruction.
  NOTE: When starting engine, CONSULT may display "Battery voltage is low. Charge battery", even in using charged battery.

When detecting EVAP vapor leak point of EVAP system

VIN REGISTRATION

In this mode, VIN is registered in ECM.

When registering VIN in ECM

SAVING DATA FOR REPLC CPU

In this mode, save data that is in ECM.

When ECM is replaced.

WRITING DATA FOR REPLC CPU

In this mode, write data stored by "SAVE DATA FOR CPU REPLC" in work support mode to ECM.

When ECM is replaced.
