DATA LIST
Tech Tips
Using the intelligent tester 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.
Note
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.
Tech Tips
Normal Condition: If no conditions are specifically stated for "idling", the shift lever should be in P or N the A/C switch should be off and all accessory switches should be off.

-20 to 0°CA:
Driving at 70 km/h (44 mph)
Yes 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 -3°CA as possible.
When Knock Feedback Value is less than -4°CA, Knock Correct Learn Value is slowly decreased.
When Knock Feedback Value is more than -2°CA, Knock Correct Learn Value is slowly increased.
*3: The base value is -3°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°CA: There is no knocking and ignition timing is advanced.
-
-6°CA: Knocking is present and the ignition timing is being retarded.
Tech Tips
If Knock Feedback Value does not change around the time when knocking occurs even though knocking continues (for example, stays at -3°CA), it can be determined that knocking is not being detected.
-
There is a problem with the knock sensor sensitivity.
-
The knock sensor is improperly installed.
-
There is a problem with a wire harness.
Possible Causes:

*1: When cranking the engine, each cylinder measures the engine speed.
In this Active Test, the fuel and ignition 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.

Tech Tips
Continue to crank the engine until the values change from the default value (51199 rpm).
-
Monitor the engine speed (Engine Speed of Cyl #1 to #4) displayed on the tester.
Tech Tips
At first, the tester displays extremely high cylinder engine speed values. After approximately 10 seconds of engine cranking, each cylinder engine speed measurement will change to the actual engine speed.
Note
-
Do not crank the engine continuously for 20 seconds or more.
-
If it is necessary to crank the engine again after Check the Cylinder Compression has been changed to ON and the engine has been cranked once, press Exit to return to the Active Test menu screen. Then change Check the Cylinder Compression to ON and crank the engine.
-
Use a fully-charged battery.

This data is taken from an Active Test in which the step position was raised in increments of 1. The EGR valve inspection in the troubleshooting procedures checks the operation of the valve by stalling the engine and raises the step position in increments of 5.
-
*5: Activate the VSV for Evap Control (Idling after warming up)
Tech Tips
Even when the Active Test is turned on (the purge VSV is opened 30%), air-fuel ratio feedback continues and control is performed so that the air-fuel ratio is the stoichiometric ratio. Therefore, by observing the change in "Short FT", it is possible to determine whether the purge VSV is actually open as well as the concentration of HC in the purge gas.
Tester Display Measurement Item/Range Normal Condition Activate the VSV for Evap Control - ▲A ▲B Active Test operation ON OFF EVAP (Purge) VSV 29.8% 0.0% Short FT #1 -9.375% 0.000% Injection (Port) 2267.0 μs 2489.0 μs AFS Voltage B1S1 3.249 V 3.205 V Tech Tips
The graphs and values above are for reference only because the feedback volume varies depending on the HC density of the purge air (HC volume absorbed by the canister).

*6: Control the VVT Linear (Bank 1)
Tester Display Measurement Item/Range Normal Condition Control the VVT Linear (Bank 1) - ▲A ▲B Active Test operation* +30% -30% VVT Change Angle #1 42.9 DegFR 0.0 DegFR VVT OCV Duty #1 67.0 % 7.0 % VVT Aim Angle #1 37.0 % 37.0 % Tech Tips
-
*: Change the control value for Control the VVT Linear to +30% or -30% in increments of 5%.
-
The Control the VVT Linear Active Test considers the value of VVT Aim Angle to be 0 and raises or lowers the duty ratio with respect to VVT Aim Angle.
-
The sum of the control value for the Control the VVT Linear Active Test and the value of VVT Aim Angle is approximately equal to the value of VVT OCV Duty.
-
When the control value for the Control the VVT Linear Active Test is changed a few times, there should not be a large discrepancy between VVT OCV Duty when the system starts advancing or retarding the timing and the rate of change of VVT Change Angle.
