VEHICLE STABILITY CONTROL SYSTEM (for Vacuum Brake Booster) DATA LIST / ACTIVE TEST


  1. DATA LIST

    Tech Tips

    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.

    Note

    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. Warm up the engine.

    2. Turn the ignition switch off.

    3. Connect the intelligent tester to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn ON the intelligent tester.

    6. Enter the following menus: Chassis / ABS/VSC/TRC / Data List.
