K121 CVT  CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM  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 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.


a.

Warm up the engine.


b.

Turn the ignition switch off.


c.

Connect the GTS to the DLC3.


d.

Turn the ignition switch to ON.


e.

Turn the GTS on.


f.

Enter the following menus: Powertrain / Engine / Data List.


g.

According to the display on the GTS, read the Data List.

Tester Display Measurement Item Range Normal Condition Diagnostic Note
Total Distance Traveled Total distance traveled Min.: 0
Max.: 1677215
- -
Total Distance Traveled - Unit Total Distance Traveled unit 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: 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.
Mass Air Flow Sensor Airflow rate from mass air flow meter sub-assembly Min.: 0 gm/sec
Max.: 655.35 gm/sec
·

1.5 to 3.3 gm/sec: Idling (engine warmed up)

·

8 to 13 gm/sec: 3000 rpm (without load)


This is the intake air amount measured by the mass air flow meter sub-assembly.
Intake Manifold Absolute Pressure Intake manifold absolute pressure Min.: 0 kPa (0 psi)
Max.: 2047.96 kPa (296.95 psi)
·

80 to 110 kPa (11.6 to 15.95 psi): Ignition switch ON

·

18 to 38 kPa (2.6 to 5.5 psi): Idling with warmed up engine


·

This is the intake manifold pressure.

·

This item is the pressure detected by the manifold absolute pressure sensor and is used for air fuel ratio control and EGR valve control.


HINT:

When the ignition switch is ON, the manifold absolute pressure and atmospheric pressure are approximately the same (standard atmospheric pressure = 101 kPa(abs) [14.65 psi(abs)]).


Intake Manifold Absolute Pressure Supported Status of Intake Manifold Absolute Pressure Unsupp or Supp Supp -
Coolant Temperature Coolant temperature Min.: -40°C (-40°F)
Max.: 140°C (284°F)

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).

ACTIVE TEST


HINT:

Using the GTS to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
