Data List/Active Test

  1. READ DATA LIST 

    HINT:

    Using the Techstream to read the Data List allows the values or states of switches, sensor, 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.

    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the Techstream on.
    4. Read the Data List according to the display on the tester.

  2. PERFORM 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 Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the Techstream on.
    4. Perform the Active Test according to the display on the tester.

      HINT:

      • The engine switch must be turned on (IG) to proceed to the Active Test using the Techstream.
      • The Active Tests of the ABS solenoid, ABS motor relay, ABS warning light and brake warning light/red (malfunction) are available when the vehicle is stopped.
      • The motors stop automatically after 5 seconds of activation to prevent them from being damaged. When the motors are driven repeatedly, certain intervals are required.
      • Each solenoid stops automatically after 2 seconds of activation to prevent them from being damaged, and can be operated again after a certain interval.
      • Do not depress the brake pedal while only the pressure reduction solenoid valves are on.
      • Do not drive 2 or more solenoids simultaneously except to operate the pressure holding solenoid valves and pressure reduction solenoid valves of each wheel.
