Sfi System -- Data List / Active Test



DATA LIST
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.
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 should be off and all accessory switches should be off.

  1. Warm up the engine.

  2. Turn the A/C switch off.

  3. Turn the engine switch off.

  4. Connect the GTS to the DLC3.

  5. Turn the engine switch on (IG).

  6. Turn the GTS on.

  7. Enter the following menus: Powertrain / Engine and ECT / Data List.

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

Diagnostic Note:
This is the ignition timing retard compensation amount determined by the presence or absence of knocking.
Ignition timing = Most retarded timing value*1 + Knock Correct Learn Value*2 + Knock Feedback Value*3 + each compensation amount
Example: 21°CA = 10° + 14° - 3°
*1: The most retarded timing value is a constant determined by the engine speed and engine load.
*2: The knock correction learned value is calculated as shown below in order to keep Knock Feedback Value as close to -3deg(CA) as possible.
When Knock Feedback Value is less than -4deg(CA), Knock Correct Learn Value is slowly decreased.
When Knock Feedback Value is more than -2deg(CA), Knock Correct Learn Value is slowly increased.
*3: The base value is -3deg (CA) and is adjusted based on the presence or absence of knocking. When there is no knocking, the value is increased, and when knocking is present, the value is decreased.
  1. -1°CA: There is no knocking and ignition timing is advanced.
  2. -6°CA: Knocking is present and the ignition timing is being retarded.
HINT:
If Knock Feedback Value does not change around the time when knocking occurs even though knocking continues (for example, stays at -3deg (CA)), it can be determined that knocking is not being detected.
Possible Causes:
  1. There is a problem with the knock sensor sensitivity.
  2. The knock sensor is improperly installed.
  3. There is a problem with a wire harness.

0 to 99.2%
Yes
Diagnostic Note:
This is the misfire detection margin.
Misfire Margin = (Misfire detection threshold - maximum engine speed variation) / misfire detection threshold x 100%
When the variation in the engine speed is large and exceeds the misfire detection threshold, the misfire count starts. Misfire margin is a measure of how much the engine speed variation can increase with respect to the threshold before the engine is determined to be misfiring.
A large value means there is a large margin for the engine speed to vary before the engine is determined to be misfiring.
Example:
When the engine is not determined to be misfiring, Misfire Margin = 52%.
When the engine is determined to be misfiring, Misfire Margin = -128 to 0%.

    HINT:
    *: When cranking the engine, the Active Test measures the speed of each cylinder. In this Active Test, the fuel of all cylinders is cut and cranking occurs 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 to the DLC3.
    4. Turn the engine switch on (IG).
    5. Turn the GTS on.
