Title: WIPER AND WASHER: WIPER AND WASHER SYSTEM: DATA LIST / ACTIVE TEST; 2006 MY LX470 [05/2005 -        ]

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 removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time.

(a) Connect the intelligent tester (with CAN VIM) to the DLC3.

(b) Turn the ignition switch ON.

(c) Read the DATA LIST according to the display on the tester.

Rain Sensor

Item

Condition

Specified Condition

Diagnostic Note

SEN COND INF

Ignition switch ON and front wiper switch except AUTO

OK

This item diagnoses the conditions inside the rain sensor.

If NG is displayed, replace the rain sensor because it has an internal problem.

SEN REACT CONDE

Ignition switch ON and front wiper switch except AUTO

OK
  • This item diagnoses the rain sensor detection conditions.
  • 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 the 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.

SEN HI TEMP INF

Ignition switch ON and front wiper switch except AUTO

OK

This item diagnoses the detection conditions of the temperature sensor in the rain sensor.

If NG is displayed, check if the temperature around the rain sensor is more than 90°C (194°F). If the temperature is 90°C (194°F) or less, replace the rain sensor because it may have an internal problem.

SEN LO TEMP INF

Ignition switch ON and front wiper switch except AUTO

OK

This item diagnoses the detection conditions of the temperature sensor in the rain sensor.

If NG is displayed, check if the temperature around the rain sensor is less than -30°C (-22°F). If the temperature is -30°C (-22°F) or more, replace the rain sensor because it may have an internal problem.

2. PERFORM ACTIVE TEST

HINT:

Performing the intelligent tester's ACTIVE TEST allows relay, VSV, actuator and other item values 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.

(a) Connect the intelligent tester (with CAN VIM) to the DLC3.

(b) Turn the ignition switch ON.

(c) Perform the ACTIVE TEST according to the display on the tester.
