DATA LIST / ACTIVE TEST

1. DATA LIST

HINT: By reading the Data List displayed on the Techstream, you can check values, including those of the switches, sensors, and actuators, without removing any parts. Reading the Data List as the first step of troubleshooting is one method of shortening diagnostic time.

NOTE: In the table below, the values listed under Normal Conditions are for 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 ignition switch to OFF
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch ON.
(e) Turn the tester ON.
(f) Enter the following menus: Powertrain / Engine and ECT / Data List.
(g) Check the values by referring to the table below.

HINT: Normal Condition: If no idling conditions are specified, transmission gear selector lever should be in the P or N (for A/T), or neutral (for M/T), and the A/C switch and all accessory switches should be OFF.









































2. ACTIVE TEST

HINT: Performing an Active Test enables components including the relays, VSV (Vacuum Switching Valve), and actuators, to be operated without removing any parts. The Active Test can be performed with the Techstream. Performing an Active Test as the first step of troubleshooting is one method of shortening diagnostic time.

Data List can be displayed during Active Tests.

(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the tester ON.
(d) Enter the following menus: Powertrain / Engine and ECT / Active Test.
(e) Perform the Active Test by referring to the table below.









HINT: *: When cranking the engine, each cylinder measures the engine rpm.

In this Active Test, the fuel and ignition of all cylinders is 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 whether or not the compression pressure is low can be determined.

1. Warm up the engine.
2. Turn the ignition switch OFF.
3. Connect the Techstream to the DLC3.
4. Turn the ignition switch ON and turn the tester ON.
5. Enter the following menus: Powertrain / Engine and ECT / Active Test / Check the Cylinder Compression.
HINT:
To display the entire Data List, press the pull down menu button next to Primary. Then select Compression.
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.
7. Fully open the throttle.
8. Crank the engine for about 10 seconds.
9. Monitor the engine speed (Engine Speed of Cyl #1 to #4) displayed on the tester.
HINT:
At first, the tester'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:
- 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 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 (Pending Codes) are set, and can detect potential malfunctions in the system. System Check can be performed with the Techstream.

(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch ON and turn the tester ON.
(c) Enter the following menus: Powertrain / Engine and ECT / Utility.
(d) Perform the System Check by referring to the table below.
(e) Turn the ignition switch to OFF.
