DATA LIST / ACTIVE TEST

1. DATA LIST

NOTICE:

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 Techstream 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.

(a) Warm up the engine.

(b) Turn the ignition switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Powertrain / Transmission / Data List.

(g) According to the display on the Techstream, read the Data List.

Vehicle Speed

Vehicle speed/

Min.: 0 km/h (0 mph)

Max.: 255 km/h (158 mph)

Actual vehicle speed

  • This is the current vehicle speed.
  • The vehicle speed is detected using the wheel speed sensors.
    • There is a delay in when the vehicle speed data is displayed. Therefore, even if the vehicle speed listed in the freeze frame data is 0 km/h (0 mph), this does not always mean that the malfunction occurred when the vehicle was stopped.

Engine Speed

Engine speed/

Min.: 0 rpm

Max.: 16383 rpm

500 to 600 rpm: Idling (shift lever in neutral, engine warmed up and A/C off)

When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.

Battery Voltage

Battery voltage/

Min.: 0 V

Max.: 65.5 V

11 to 14 V: Idling

If 11 V or less, characteristics of some electrical components may change.

BATT Voltage

Battery voltage/

Min.: 0 V

Max.: 79.998 V

11 to 14 V: Idling

If 11 V or less, characteristics of some electrical components may change.
