Tire Pressure Warning System (For Hatchback) -- Data List / Active Test



READ 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.

  1. Turn the ignition switch off.

  2. Connect the Techstream to the DLC3.

  3. Turn the ignition switch to ON.

  4. Turn the Techstream on.

  5. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

  6. According to the display on the Techstream, read the Data List.

    HINT:
    *1: Displayed only when the ID No. is not registered.
    *2: It may take a few minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24 (YARIS_NCP93 RM000000ZUQ07PX.html).
    *3: This item is displayed on the Techstream, however, it is not used for this vehicle.

PERFORM ACTIVE TEST
Using the Techstream to perform Active Tests allows the 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.

  1. Turn the ignition switch off.

  2. Connect the Techstream to the DLC3.

  3. Turn the ignition switch to ON.

  4. Turn the Techstream on.

  5. Enter the following menus: Body Electrical / Combination Meter / Active Test.

  6. Check the operation by referring to the table below.
