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.
• 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 by-pass 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 IDLE RPM ADJ
  
  Use when setting target idle speed. This function is usually unnecessary.
• TARGET IGNITION TIMING ADJ
  
  Use when adjusting target ignition timing. After adjustment, verify target ignition timing with a timing light. This function is usually unnecessary.
