Steering Lock System -- Data List / Active Test



READ DATA LIST
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 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 when deciding whether a part is faulty or not.

  1. Turn the engine switch off.

  2. Connect the intelligent tester to the DLC3.

  3. Turn the engine switch on (IG).

  4. Turn the intelligent tester on.

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

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

PERFORM ACTIVE TEST
HINT:
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.

  1. Connect the intelligent tester to the DLC3.

  2. Turn the engine switch on (IG).

  3. Turn the intelligent tester on.

  4. Enter the following menus: Body / Power Source Control / Active Test.

  5. According to the display on the intelligent tester, perform the Active Test.

    Power Source Control
    Tester Display
    		Test Part
    		Control Range
    		Diagnostic Note
