WIPER AND WASHER SYSTEM (w/ Rain Sensor) - DATA LIST / ACTIVE TEST

READ DATA LIST

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 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.

In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

Warm up the engine.

Turn the engine switch off.

Connect the intelligent tester to the DLC3.

Turn the engine switch on (IG).

Turn the intelligent tester on.

Enter the following menus: Body / (desired system) / Data List.

According to the display on the intelligent tester, read the "Data List".

PERFORM ACTIVE TEST

Using the intelligent tester to perform Active Tests allows relays, VSVs, 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.

When a Body No. 5 (windshield wiper ECU) related front wiper switch is on, Active Test items related to the front wiper switch are prohibited (double operation prohibition). Check that the front wiper switches are off before performing Active Tests.

Warm up the engine.

Turn the engine switch off.

Connect the intelligent tester to the DLC3.

Turn the engine switch on (IG).

Turn the intelligent tester on.

Enter the following menus: Body / (desired system) / Active Test.

According to the display on the intelligent tester. perform the "Active Test".
