CHARGING SYSTEM(w/o Stop And Start System) DATA LIST / ACTIVE TEST


  1. DATA LIST

    Tech Tips

    Using the GTS 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 GTS to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the GTS on.

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

    7. According to the display on the GTS, read the Data List.

      Powertrain > Engine and ECT > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Battery voltage Battery voltage

      Max.: 65.535 V

      		 11 to 14 V: Idling If the result is not as specified, abnormal battery voltage is suspected.
      Battery current Battery current

      Min.: -125 A

      Max.: 124.996 A

      Changes according to alternator output

      (While driving after engine warmed up)

      		 If the result is not as specified, a malfunction of the charging control system is suspected.
      Battery Temperature Battery fluid temperature

      Min.: -40°C (-40°F)

      Max.: 6513.5°C (11756°F)

      Changes according to actual temperature

      (While driving after engine warmed up)

      		 If the result is not as specified, a malfunction of the charging control system is suspected.
      Alternator Output Duty Generator output duty

      Min.: 0%

      Max.: 399.993%

      Changes according to alternator output

      (During charging control)

      		 If the result is not as specified, a malfunction of the charging control system is suspected.
      Alt Vol - Non Active Test Requested voltage when regulator not under forced activation

      Min.: 0 V

      Max.: 79.998 V

      13.2 to 14.8 V

      (After engine start (varies with regulator temperature or driving conditions))

      		 Active Test support data
      Alt Vol - Active Test Requested voltage when regulator under forced activation

      Min.: 0 V

      Max.: 79.998 V

      Approximately same as requested output voltage when Active Test item "Control the Voltage of Alternator" is performed:

      After engine start

      		 Active Test support data

      Tech Tips

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

  2. ACTIVE TEST

    Tech Tips

    Using the GTS 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 GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

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

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

      Powertrain > Engine and ECT > Active Test
      Tester Display Measurement Item Control Range Diagnostic Note
      Control the Voltage of Alternator Requested output voltage of generator regulator during forced activation Between 13.2 and 14.8 V Test is possible after engine start
