DATA LIST / ACTIVE TEST

1. 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.
NOTE:
In the table below, the values listed under Normal Condition are reference only. Do not depend solely on these values when determining whether or not a part is faulty.

(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).
(e) Turn the Techstream ON.
(f) Enter the following menus: Powertrain / Engine / Data List / All Data /
(g) Check the values by referring to the table below.





























































HINT:
- Normal condition: If no idling conditions are specified, the transmission gear selector lever should be in the N or P position, and the A/C switch and all accessory switches should be OFF.
- *: Data List values are only displayed when performing the following Active Tests: Control the VVT-iE Linear (Bank1), Control the VVT-iE Linear (Bank2), Control the Exhaust Linear (Bank1) and Control the Exhaust Linear (Bank2). For other Active Tests, the Data List value will be 0.

2. ACTIVE TEST
HINT: Using the Techstream to perform the Active Tests allows relays, VSVs and 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 test early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
- Data List can be displayed during Active Test.

(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream ON.
(d) Enter the following menus: Powertrain / Engine / Active Test /
(e) According to the display on the Techstream, perform the "Active Test".













HINT: *: When cranking the engine, each cylinder measures the engine rpm.
In this Active Test, the fuel and ignition of all cylinders are cut, and cranking occurs for approximately 10 seconds. Then, each cylinder measures the engine rpm. If a cylinder's engine rpm is higher than the other, that cylinder's compression pressure is compared to the other, and is determined whether it is low or not.

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) and turn the Techstream ON.
5 Enter the following menus: Powertrain / Engine / Active Test / Check the Cylinder Compression.
HINT: If the results are not displayed normally, select the display items from the Data List before performing the Active Test. Enter the following menus: Powertrain / Engine / Data List / Compression / Engine Speed of Cyl #1, Engine Speed of Cyl #2, Engine Speed of Cyl #3, Engine Speed of Cyl #4, Engine Speed of Cyl #5, Engine Speed of Cyl #6, Engine Speed of Cyl #7, Engine Speed of Cyl #8 and Av Engine Speed of All Cyl.

6 While the engine is not running, press the RIGHT or LEFT button to change the Check the Cylinder Compression to ON.
HINT: After performing the above procedure, the Active Test's Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited, and each cylinder's engine rpm measurement will enter standby mode.

7 Crank the engine for about 10 seconds.
8 Monitor the engine speed (Engine Speed of Cyl #1 to #8, Av Engine Speed of All Cyl) displayed on the Techstream.
HINT: At first, the Techstream's display will show each cylinder's engine rpm measurement to be extremely high. After approximately 10 seconds of engine cranking, each cylinder's engine rpm measurement will change to the actual engine rpm.
NOTICE:
- After the Active Test's Check the Cylinder Compression is turned ON, it will automatically turn off after 255 seconds.
- When the Check the Cylinder Compression test is OFF and the engine is cranked, the engine will start.
- If the Check the Cylinder Compression test needs to be performed after it is turned ON and performed once, press EXIT to return to the Active Test menu screen. Then perform the Check the Cylinder Compression test again.
- Use a fully-charged battery.

3. SYSTEM CHECK
HINT: Performing a System Check in the Utility menu 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 set, and can detect potential malfunctions in the system.

(a) Connect Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream ON.
(d) Enter the following menus: Powertrain / Engine / Utility /
(e) Perform the System Check by referring to the table below.
