Lexus RX (RX 350L, RX450h) 2016-2022 Repair Manual: Data List / Active Test

DATA LIST / ACTIVE TEST

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 engine switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the engine switch on (IG).

(e) Turn the Techstream on.

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

(g) Read the Data List according to the display on the Techstream.

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.
    • Vehicle speed data is delayed when it 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

550 to 650 rpm: Engine idling (shift lever in N, 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.

Calculate Load

Load calculated by ECM

Min.: 0%

Max.: 100%

-

  • This is the engine load calculated based on the estimated intake manifold pressure.
  • Calculate Load = Actual intake manifold pressure / maximum intake manifold pressure x 100 (%)

    (For example, when the actual intake manifold pressure is the same as ambient pressure, Calculate Load is 100%.)

Coolant Temperature

Engine coolant temperature

Min.: -40°C (-40°F)

Max.: 140°C (284°F)

75 to 100°C (167 to 212°F): After warming up

This is the engine coolant temperature.

HINT:

  • After warming up the engine, the engine coolant temperature is 75 to 100°C (167 to 212°F).
  • After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature are approximately equal.
  • If the value is -40°C (-40°F), or higher than 135°C (275°F), the sensor circuit is open or shorted.
  • Check if the engine overheats when the value indicates higher than 135°C (275°F).

Intake Air Temperature

Intake air temperature

Min.: -40°C (-40°F)

Max.: 140°C (284°F)

Equivalent to temperature at location of mass air flow meter sub-assembly

  • After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature are approximately equal.
  • If the value is lower than -40°C (-40°F), or higher than 128°C (262°F), the sensor circuit is open or shorted.

Ambient Temperature

Ambient temperature

Min.: -40°C (-40°F)

Max.: 215°C (419°F)

Equivalent to ambient air temperature

This is the ambient temperature.

HINT:

  • After a long soak, the engine coolant temperature, engine oil temperature, intake air temperature and ambient air temperature are approximately equal.

  • 64 to 96%: Accelerator pedal fully depressed (engine running)

The No. 1 throttle position sensor output is converted using 5 V = 100%.

HINT:

If there are no throttle position sensor DTCs stored, it is possible to conclude that the throttle position sensor system is normal.

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.
    • Vehicle speed data is delayed when it 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

  • After warming up the engine, the engine coolant temperature is 75 to 100°C (167 to 212°F).
  • After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature are approximately equal.
  • If the value is -40°C (-40°F), or higher than 135°C (275°F), the sensor circuit is open or shorted.
