DATA LIST / ACTIVE TEST
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.
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Put the engine in Inspection Mode (Maintenance Mode).

Knocking feedback value |
Min.: -1024 deg(CA), Max.: 1023.9 deg(CA) |
-20 to 0 deg(CA): Driving at 70 km/h (43 mph) (Engine running) |
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 F/B Value*3 + each compensation amount Example: 21 deg(CA) = 10 deg(CA) + 14 deg(CA) - 3 deg(CA) *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 F/B Value as close to -3 deg(CA) as possible. When Knock F/B Value is less than -4 deg(CA), Knock Correct Learn Value is slowly decreased. When Knock F/B Value is higher than -2 deg(CA), Knock Correct Learn Value is slowly increased. *3: The base value is -3 deg(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. HINT: 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.

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.
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Put the engine in Inspection Mode (Maintenance Mode).

HINT:
- While performing the Active Test, air fuel ratio feedback control and feedback learning are stopped.
- Usually, the value of A/F (O2) Sensor Voltage B1S1 drops below 3.1 V when the control value for Control the Injection Volume for A/F Sensor is changed to 12.5%.
- Usually, the value of A/F (O2) Sensor Voltage B1S1 changes to 3.4 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 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:
- 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.
- 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.
