Data List/Active Test

WARNING: This page is about a different car, the 2007 Lexus RX 350. However, it is still accessible from the selected car via links, so may be relevant.
  1. READ DATA LIST 

    HINT:

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

    1. Connect the intelligent tester to the DLC3.
    2. Turn the ignition switch on.
    3. Read the DATA LIST according to the display on the tester.

      • 1 is OK, but CRUISE main indicator light does not illuminate → Cruise main indicator light, wire harness, or ECM failure
  2. ACTIVE TEST 

    HINT:

    Performing the intelligent tester's ACTIVE TEST allows relays, VSVs, actuators, 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 to the DLC3.
    2. Turn the ignition switch on.
    3. Perform the ACTIVE TEST according to the display on the tester.

      HINT:

      The ignition switch must be turned on to proceed to the ACTIVE TEST using the intelligent tester.
