Variable Gear Ratio Steering System -- Data List / Active Test


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.

  2. Turn the engine switch on (IG).

  3. Turn the tester on.

  4. Enter the following menus: Chassis / VGRS / Data List.

    NOTICE:
    *1: This data must be "Valid" before proceeding with any steering adjustment. If "Invalid" is displayed, perform the steering angle sensor initialization procedure. If the steering actuator or steering control ECU has been replaced, perform VGRS system calibration (steering angle adjustment).
    HINT:
    *2: If "Rec" is displayed, enter the VGRS menu on the intelligent tester, select record clearance, and follow the prompts to set to "Unrec".

ACTIVE TEST
HINT:
Using the intelligent tester to perform Active Test 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 Test early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Test.

  1. Connect the intelligent tester to the DLC3.

  2. Turn the engine switch on (IG).

  3. Turn the tester on.

  4. Enter the following menus:
    Body / Combination meter / Active Test.

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

    Combination Meter:
    Tester Display
    		Test Part
    		Control Range
    		Diagnostic Note
    Master Warning
    		Master warning light
    		OFF/ON
    		Confirm that the vehicle is stopped and the engine is running.
