CHARGING SYSTEM 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 the intelligent tester on.

    6. Enter the following menus: Powertrain / Engine and ECT / Data List.

    7. Check the values by referring to the table below.

    Engine and ECT
    Tester Display Measurement Item/Range Normal Condition Diagnostic Note
    Battery Voltage

    Battery voltage:

    Min.: 0 V, Max.: 65.5 V

    		 11 to 14 V: Idling -
    Battery Current

    Battery current:

    Min.: -125 A, Max.: 124.9 A

    		 - Charging control service data
    Battery Temperature

    Battery temperature:

    Min.: -45°C, Max.: 156.4°C

    		 - Charging control service data
    Alternator Output Duty

    Generator output duty:

    Min.: 0%, Max.: 100%

    		 - Electricity generated by generator is output through duty ratio charging control service data
    Alt Vol - Non Active Test

    Request voltage when regulator not under forced activation:

    Min.: 0 V, Max.: 20 V

    		 Battery electrolyte temperature varies (12.5 to 14.8 V) while driving: After engine start

    Alternator regulator output voltage:

    When performing Active Test, value is 0 V
    Alt Vol - Active Test

    Request voltage when regulator under forced activation:

    Min.: 0 V, Max.: 20 V

    		 Request instruction voltage value: After engine start

    Charging control service data:

    When performing Active Test, value is 0 V

    Tech Tips

    Normal Condition: If no idling conditions are specified, the transmission gear shift lever should be in N or P, and the A/C switch and all accessory switches should be off.

  2. ACTIVE TEST

    Tech Tips

    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 ignition switch to ON.

    3. Turn the intelligent tester on.

    4. Enter the following menus: Powertrain / Engine and ECT / Active Test.

    5. Perform the Active Test by referring to the table below.
