Title: K120 / K121 (CVT): K120 CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM: DATA LIST / ACTIVE TEST; 2019 - 2022 MY Corolla Corolla Hatchback [06/2018 - 09/2022]

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.

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

(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.

Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
Total Distance Traveled	Total distance traveled	Min.: 0 Max.: 16777215	-	-
Total Distance Traveled - Unit	Unit for Total Distance Traveled	km or mile	-	-
Vehicle Speed	Vehicle speed	Min.: 0 km/h (0 mph) Max.: 255 km/h (158 mph)	Actual 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	750 to 850 rpm: Engine idling (shift lever in P, 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 pressure. Calculate Load = Estimated intake pressure / maximum intake pressure x 100 (%) (For example, when the estimated intake pressure is the same as atmospheric pressure, Calculate Load is 100%.)
Coolant Temperature	Coolant temperature	Min.: -40°C (-40°F) Max.: 140°C (284°F)	75 to 100°C (167 to 212°F): After warming up	HINT: After warming up the engine, the engine coolant temperature will be 75 to 100°C (167 to 212°F). After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature will be 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 if the value indicated is 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	HINT: After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature will be approximately equal. If the value is -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	HINT: After a long soak, the engine coolant temperature, engine oil temperature, intake air temperature and ambient air temperature are approximately equal.
Engine Run Time	Engine run time	Min.: 0 sec. Max.: 65535 sec.	Time elapsed since engine started.	This is the time elapsed since the engine was started. HINT: The time is counted only while the engine is running.
Battery Voltage	Battery voltage	Min.: 0 V Max.: 65.5 V	11 to 14 V: Engine idling	If 11 V or less, characteristics of some electrical components may change.
Glow Indicator Supported	Glow indicator supported	Unsupp or Supp	-	-
Throttle Position Sensor No.1 Voltage %	Absolute throttle position sensor (No. 1)	Min.: 0% Max.: 100%	10 to 22%: Accelerator pedal fully released 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.

HINT:

*1: An engine warmup is defined as the engine coolant temperature rising 20°C (68°F) or more and reaching a temperature of 70°C (158°F) or more after the engine is started.
*2:
- Avail: The monitor is available on this vehicle.
- Not Avl: The monitor is not available on this vehicle.
- Incmpl / Compl: The item changes from Incmpl to Compl if the monitor was completed at least once at sometime in the past. This item does not change when the engine switch is turned off. However, it will change to Incmpl when DTCs are cleared or the cable is disconnected from the negative (-) battery terminal.
- Monitor result (mode 06): The last judgment result is output. This is not cleared when the engine switch is turned off, but is cleared when DTCs are cleared.
*3:
- Enable: The monitor is available on the vehicle.
- Unable: The monitor is not available on the vehicle.
- Incmpl / Compl: The item changes from Incmpl to Compl if the monitor was completed during the current trip. The item changes back to Incmpl when the engine switch is turned off.
- Monitor result (mode 06): The last judgment result is output. This is not cleared when the engine switch is turned off, but is cleared when DTCs are cleared. Therefore, only when DTCs are cleared at the beginning of a trip does the system monitor (Test Result [Monitor Status]) and monitor result (mode 06) match.
*4: Refer to DTC P070513.
