Function Inspection

  1. Operation explanation
    1. Entry ignition function (with automatic transmission):
      1. If the electrical key transmitter sub-assembly is in the vehicle interior detection area and the brake pedal is depressed, you can press the engine switch and start the engine.
      2. If the electrical key transmitter sub-assembly is in the vehicle interior detection area and the brake pedal is not depressed, you can press the engine switch to change the power mode. The power mode changes each time you press the engine switch, in the following order: OFF →ACC ON→ IG ON →OFF.
      3. In IG OFF, after you enter the vehicle interior carrying the electrical key transmitter sub-assembly, if you press the engine switch without depressing the brake pedal, the power mode switches to ACC, and the entry key indicator light in the combination meter assembly blinks green.
      4. With the engine switch turned off, after you enter the vehicle interior holding the electrical key transmitter sub-assembly in your hand, and with the shift lever put in P, if you depress the brake pedal, the entry key indicator light in the combination meter assembly will light up green.
      5. If you press the engine switch when the entry key indicator light of the combination meter assembly is lit up green, the engine will start.
    2. Changing the power mode when the electrical key transmitter sub-assembly doesn't operate properly due to radio wave interference or the battery of the electrical key transmitter sub-assembly being drained (for automatic transmission):
      1. Use the integrated mechanical key to unlock the door, hold the electrical key transmitter sub-assembly, and enter the vehicle interior.
      2. Depress the brake pedal and hold the ornament side of the electrical key transmitter sub-assembly up to the engine switch.
      3. The buzzer sounds and the vehicle turns to IG ON.
        NOTE: If the entry cancel function has been customized, the power mode changes to on (ACC).
    3. Starting the engine when the electrical key transmitter sub-assembly doesn't operate properly due to radio wave interference or the battery of the electrical key transmitter sub-assembly being drained (for automatic transmission):
      1. Use the integrated mechanical key to unlock the door, hold the electrical key transmitter sub-assembly, and enter the vehicle interior.
      2. Depress the brake pedal, move the shift lever in P, and hold the ornament side of the electrical key transmitter sub-assembly up to the engine switch.
      3. The buzzer sounds and the vehicle turns to IG ON. When the entry key indicator light of the combination meter assembly lights up green, press the engine switch while pressing the brake pedal, and start the engine.
        NOTE: If the entry cancel function has been customized, the power mode changes to on (ACC).
    4. Entry ignition function (with manual transmission):
      1. If the electrical key transmitter sub-assembly is in the vehicle interior detection area and the clutch pedal is depressed, you can press the engine switch and start the engine.
      2. If the electrical key transmitter sub-assembly is in the vehicle interior detection area and the clutch pedal is not depressed, you can press the engine switch to change the power mode. The power mode changes each time you press the engine switch, in the following order: OFF →ACC ON→ IG ON →OFF.
      3. In IG OFF, after you enter the vehicle interior carrying the electrical key transmitter sub-assembly, if you press the engine switch without depressing the clutch pedal, the power mode switches to ACC, and the entry key indicator light in the combination meter assembly blinks green.
      4. In IG OFF, after you enter the vehicle interior carrying the electrical key transmitter sub-assembly, if you depress the clutch pedal, the entry key indicator light in the combination meter assembly will light up green.
      5. If you press the engine switch when the entry key indicator light of the combination meter assembly is lit up green, the engine will start.
    5. Changing the power mode when the electrical key transmitter sub-assembly doesn't operate properly due to radio wave interference or the battery of the electrical key transmitter sub-assembly being drained (for manual transmission):
      1. Use the integrated mechanical key to unlock the door, hold the electrical key transmitter sub-assembly, and enter the vehicle interior.
      2. Depress the clutch pedal and hold the ornament side of the electrical key transmitter sub-assembly up to the engine switch.
      3. The buzzer sounds and the vehicle turns to IG ON.
        NOTE: If the entry cancel function has been customized, the power mode changes to ACC.
    6. Starting the engine when the electrical key transmitter sub-assembly doesn't operate properly due to radio wave interference or the battery of the electrical key transmitter sub-assembly being drained (for manual transmission):
      1. Use the integrated mechanical key to unlock the door, hold the electrical key transmitter sub-assembly, and enter the vehicle interior.
      2. Depress the clutch pedal and hold the ornament side of the electrical key transmitter sub-assembly up to the engine switch.
      3. The buzzer sounds and the vehicle turns to IG ON.
  2. Function inspection for the entry ignition
    1. Inspect the entry ignition function (only for automatic transmission).
      1. In IG OFF, with the shift lever in P, while carrying the electrical key transmitter sub-assembly, depress the brake pedal, and check that the entry key indicator light of the combination meter assembly lights up green. If the entry key indicator light of the combination meter assembly lights up green, press the engine switch, and check that the engine starts.
      2. Without depressing the brake pedal, after putting the vehicle in IG OFF, press the electrical key transmitter sub-assembly, and check that the power mode changes in the following way: OFF →ACC ON →IG ON →OFF. However, in IG ON, if the shift lever is in a position other than P, the power mode will not turn OFF but will turn to ACC ON.
      3. Turn off the vehicle's engine, press the engine switch, and check that it turns to IG OFF (the engine stops, and all electrical systems turn off). However, with the vehicle stopped, if the shift lever is in a position other than P, even if you press the engine switch, the power mode will not turn OFF but will turn to ACC ON. In this case, move the shift lever back into P, press the engine switch, and check that the power mode changes to OFF. After the power turns OFF, open the door and check that the steering lock operates.
      4. Inspect the operation range of the entry ignition (front floor). In one of the inspection points, place the electrical key transmitter sub-assembly of the front seat in the direction shown in the figure, and check that the engine starts.
