DATA LIST

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.

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:

Normal Condition: If no conditions are specifically stated for "idling", the shift lever should be in N or P, the A/C switch and all accessories should be off.

If Knock F/B Value does not change around the time when knocking occurs even though knocking continues (for example, stays at -3 deg(CA)), it can be determined that knocking is not being detected.

Possible Causes:
  • There is a problem with the knock control sensor sensitivity.
  • The knock control sensor is improperly installed.
  • There is a problem with a wire harness.

Knock Correct Learn Value

Knocking correction learned value

Min.: -1024 deg(CA), Max.: 1023.9 deg(CA)

-

  • Refer to "Knock F/B Value".
  • When there is knocking or a lack of power, compare the values of following items to another vehicle of the same model.
    • Engine Speed
    • Calculate Load
    • Ignition Timing Cylinder #1
    • Knock F/B Value
    • Knock Correct Learn Value
  • Knock Correct Learn Value is large: There is no knocking and the ignition timing is advanced.
  • Knock Correct Learn Value is small: Knocking is present and the ignition timing is being retarded.

HINT:

When knocking continues even though Knock Correct Learn Value is less than that of the vehicle being used for comparison (in other words, the ignition timing is being retarded but the knocking does not stop), there may be a buildup of deposits or other such problems due to deterioration over time (oil entering the cylinders, poor quality fuel, etc.).

ACTIVE TEST

HINT:

  • Using the Techstream 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.
  • As DTCs may be stored when an Active Test or learning is performed, make sure to clear the DTCs before returning the vehicle to the customer.

(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).

While performing this Active Test, the fuel injection and ignition of all cylinders is cut. The engine must then be cranked for approximately 10 seconds. At this time, the speed of each cylinder is measured. If the speed of one cylinder is more than the other cylinders, it can be determined that the compression pressure of that cylinder is lower than the other cylinders.

  1. Warm up the engine.
  2. Turn the engine switch off.
  3. Connect the Techstream to the DLC3.
  4. Turn the engine switch on (IG).

    • Usually, the value of O2 Sensor Voltage B1S2 changes to 0.55 V or higher when the control value for Control the Injection Volume for A/F Sensor is changed to 12.5%.
    • Usually, the value of O2 Sensor Voltage B1S2 drops below 0.4 V when the control value for Control the Injection Volume for A/F Sensor is changed to -12.5%.
    • The air fuel ratio sensor has an output delay of a few seconds and the heated oxygen sensor has a maximum output delay of approximately 20 seconds.
    • If the sensor output voltage does not change (almost no reaction) while performing the Active Test, the sensor may be malfunctioning.

    HINT:

    • Even when the Active Test is performed (the purge VSV is opened approximately 50%), the ECM performs air fuel ratio feedback to maintain the air fuel ratio at the stoichiometric ratio. Therefore, by observing the change in the Data List item "Injector Cylinder #1 (Port)", it is possible to determine whether the purge VSV is actually open.
    • The graphs and values above are for reference only because the fuel injection volume (compensation volume) varies depending on the HC density of the purge air from the canister.

SYSTEM CHECK

(a) EVAPORATIVE SYSTEM CHECK

HINT:

Performing a System Check enables the system, which consists of multiple actuators, to be operated without removing any parts. In addition, it can show whether or not any DTCs are stored, and can detect potential malfunctions in the system. The System Check can be performed with the Techstream.

(1) Connect the Techstream to the DLC3.

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

(3) Turn the Techstream on.
