Caution / Notice / Hint

WARNING:
  • Strictly observe posted speed, limits, traffic laws and road conditions.

  • Do not drive the vehicle with the cable of the GTS contacting the pedals, shift lever or steering wheel.
  • Driving the vehicle with the cable of the GTS contacting these areas could impede vehicle control, resulting in a serious accident.
  • Do not operate the GTS while driving the vehicle.

  • Operating the GTS while driving the vehicle will prevent you from paying sufficient attention to vehicle surroundings, and could result in a serious accident.
NOTE:
  1. DATA LIST 
    NOTE:

    In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

    HINT: 

    Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

    1. Warm up the engine.
    2. Read the Data List according to the display on the GTS.

      NT Sensor Speed

      HINT: 

      • NT Sensor Speed is always 0 while driving: Open or short in the sensor or circuit.
      • NT Sensor Speed is always more than 0 and less than 300 rpm while driving the vehicle at 50 km/h (31 mph) or more: Sensor malfunction, improper installation, or intermittent connection malfunction in the circuit.
