SIMULATION ITEM TABLE

Item Applicable component Operation Operation condition
Engine condition Other condition
FP Fuel pump Select OFF/ON to forcibly drive/stop the fuel pump.
  • Under the following conditions:
    • Ignition is switched ON (engine off)
      • Idle (no load)
 Not applicable
INJ_1 Fuel injector No. 1 Select OFF to forcibly stop the fuel injector No. 1. Not applicable
WARNING:
  • Do not use the simulation function while the vehicle is being driven. Stopping the fuel ejection causes the engine to stall which may cause the brakes to not function.
INJ_2 Fuel injector No. 2 Select OFF to forcibly stop the fuel injector No. 2.
INJ_3 Fuel injector No. 3 Select OFF to forcibly stop the fuel injector No. 3.
INJ_4 Fuel injector No. 4 Select OFF to forcibly stop the fuel injector No. 4.
