Title: 2UZ-FE ENGINE CONTROL: SFI SYSTEM: DATA LIST / ACTIVE TEST (2008 Sequoia)

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.

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) Warm up the engine.

(b) Turn the ignition switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream ON.

(f) Enter the following menus: Powertrain / Engine / Data List.

(g) According to the display on the Techstream, use the Data List.

2. 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) Warm up the engine.

(b) Turn the ignition switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream ON.

(f) Enter the following menus: Powertrain / Engine / Active Test

(g) According to the display on the Techstream, perform the Active Test.

Check the Cylinder Compression*

Check the cylinder compression pressure

ON/OFF

Fuel injection and ignition stop in all cylinders.

HINT:

*: 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. Then, each cylinder measures the engine speed. If a cylinder engine speed is higher than the other, that cylinder 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 to ON.
  5. Turn the Techstream ON.
  6. Enter the following menus: Powertrain / Engine / 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.

  7. 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 Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited, and each cylinder engine speed measurement will enter standby.

  8. Fully open the throttle.
  9. Crank the engine for about 10 seconds.
  10. Monitor the engine speed (Engine Speed of Cyl #1 to #8) displayed on the Techstream.

    HINT:

    At first, the Techstream 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.

    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 are stored, and can detect potential malfunctions in the system. The System Check can be performed with the Techstream.

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream ON.

(d) Enter the following menus: Powertrain / Engine / Utility

(e) Perform the System Check by referring to the table below.
