Work Support Mode

This mode can be used for the following functions:

• FUEL PRESSURE RELEASE
  
  Use to release fuel pressure. Fuel pump will stop by touching START during engine idling. Crank a few times after engine stalls.
• IDLE AIR VOL LEARN
  
  Use to perform idle air volume learning. The idle air volume that keeps the engine within the specified range is memorized in ECM.
• SELF-LEARNING CONT
  
  Use to clear the coefficient of self-learning control value. Air/fuel mixture ratio returns to the original coefficient.
• EVAP SYSTEM CLOSE
  
  Use when testing EVAP system for leaks. This will open vacuum cut valve bypass valve and close EVAP canister vent control valve in order to seal EVAP system under the following conditions:
  • Ignition switch ON.
  • Engine not running.
  • Ambient temperature is above 32°F (0°C).
  • No vacuum and no high pressure in EVAP system.
  • Fuel tank temperature is more than 32°F (0°C).
  • Within 10 minutes after starting EVAP SYSTEM CLOSE.

  When trying to execute EVAP SYSTEM CLOSE when above conditions are not met, CONSULT-II will discontinue it and display appropriate instruction.

  NOTE: When starting engine, CONSULT-II may display BATTERY VOLTAGE IS LOW. Charge battery, even if using charged battery.
• TARGET IGNITION TIMING ADJ
  
  Use when adjusting target ignition timing. After adjustment, verify target ignition timing with a timing light. Once the TARGET IDLE RPM ADJ has been done, the Idle Air Volume Learning procedure will not be completed. This function is usually unnecessary.
• TARGET IDLE RPM ADJ
  
  Use when setting target idle speed. This function is usually unnecessary.
