Data List / Active Test

  1. READ DATA LIST 

    HINT:

    Using the intelligent tester's DATA LIST allows switch, sensor, actuator and other item values to be read without out removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time.

    1. Connect the intelligent tester (with CAN VIM) to the DLC3.
    2. Turn the power switch ON (IG).
    3. Turn the intelligent tester on.
    4. Read the DATA LIST according to the display on the tester.

  2. PERFORM ACTIVE TEST 

    HINT:

    Performing the intelligent tester's ACTIVE TEST allows relay, VSV, actuator and other items to be operated without removing any parts. Performing the ACTIVE TEST early in troubleshooting is one way to save time. The DATA LIST can be displayed during the ACTIVE TEST.

    1. Connect the intelligent tester (with CAN VIM) to the DLC3.
    2. Turn the power switch ON (IG).
    3. Turn the intelligent tester on.
    4. Perform the ACTIVE TEST according to the display on the tester.

      HINT:

      • The power switch must be turned ON (IG) to proceed to the ACTIVE TEST using the intelligent tester.
      • The ACTIVE TESTs of the ABS solenoid, ABS motor relay, ABS warning light and brake warning light 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.
