SFI SYSTEM (w/ Electronic Throttle Control 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 determining whether or not a part is faulty.


    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 tester on.

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

  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. 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 tester on.

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

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

      Tester Display Test Part Control Range
      Injector Volume (INJ VOL)

      [Test Details] Control injection volume Min.: -12.5%, Max.: 24.7%

      [Vehicle Condition] Engine speed: 3000 rpm or less

      All injectors are tested at once

      Injection volume is gradually changed between -12.5% and 24.7%
      A/F Control (A/F CONTROL)

      [Test Details] Control injection volume -12.5 or 25% (Change injection volume by -12.5% or 25%)

      [Vehicle Condition] Engine speed: 3000 rpm or less

      		 Following A/F Control procedure enables technician to check and graph voltage outputs of both heated oxygen sensors. To display graph, enter the following menus: View / Line graph 1 or Line graph 2
      A/C Cut Signal A/C Cut Signal OFF or ON -
      Fuel Pump

      [Test Details] Control fuel pump speed OFF or ON

      [Vehicle Condition] Vehicle stopped and engine idling

      ON: Rough idling or engine stalling

      OFF: Normal engine speed
      FC IDL Prohibit (FC IDL PROHBT) [Test Details] Control idle fuel cut prohibition OFF or ON During idling

      Tech Tips

      Connecting TC and TE1 may cause the idle to be a little rough, but this is not a part malfunction.
