WIPER AND WASHER: WIPER AND WASHER SYSTEM: DATA LIST / ACTIVE TEST

DATA LIST / ACTIVE TEST

1. READ DATA LIST
HINT: Using the intelligent tester or Techstream 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.
NOTICE:
In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values deciding whether a part is faulty or not.

(a) Warm up the engine.
(b) Turn the power switch OFF.
(c) Conned the intelligent tester or Techstream to the DLC3.
(d) Turn the power switch ON (IG).
(e) Turn the tester on.
(f) Using the intelligent tester or Techstream enter the following menus.
(1) Intelligent tester Select: DIAGNOSIS / OBD / MOBD / (desired system) / DATA LIST / ALL.
(2) Techstream - Select: Body Electrical / (desired system) / DATA LIST.
(g) According to the display on tester, read the "Data List"

2. PERFORM ACTIVE TEST
HINT: Using the intelligent tester or Techstream 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.
NOTICE:
When a BODY (front controller) related vehicle switch is ON, Active Test items related to the vehicle switch are prohibited (double operation prohibition). Check that the vehicle switches are OFF before performing Active Tests.

(a) Warm up the engine.
(b) Turn the power switch OFF.
(c) Connect the intelligent tester or Techstream to the DLC3.
(d) Turn the power switch ON (IG).
(e) Turn the tester on.
(f) Using the Intelligent tester or Techstream enter the following menus.
(1) Intelligent tester Select DIAGNOSIS / OBD / MOBD / (desired system) / ACTIVE TEST / ALL.
(2) Techstream - Select Body Electrical / (desired system) / Active Test.
(g) According to the display on tester, perform the "ACTIVE TEST"
