HINT:
Using the intelligent tester 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 nonintrusive inspection can be very useful as 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 intelligent tester to the DLC3.

  2. Turn the engine switch on (IG).

  3. Read the DATA LIST.

    If NG is displayed, clean the outside of the windshield where the rain sensor is installed.
    Also Confirm the following:
    - The sensor is correctly installed.
    - No air bubbles are trapped between the windshield and the sensor tape.
    - The sensor tape is properly placed between the windshield and sensor.
    - The sensing portion of the sensor (contact surface with the windshield) is clean.
    If no defects are found, replace the rain sensor because it may have an internal problem.

PERFORM ACTIVE TEST
HINT:
Performing the 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 engine switch on (IG).

  3. Perform the ACTIVE TEST.
