    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform steps [C] and [D] again and, if necessary, extend the driving time.

Tech Tips

Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. READ VALUE USING GTS (STARTER SIGNAL)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / Starter Signal.


      Powertrain > Engine and ECT > Data List
      Tester Display
      Starter Signal

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

      Standard
      Condition Starter Signal
      Engine switch on (IG) OFF

    6. According to the display on the GTS, read the Data List while the vehicle is being driven with an engine speed of 1000 rpm or more at a vehicle speed of 20 km/h (12.43 mph) or more.

      CAUTION:

      When performing the confirmation driving pattern, obey all speed limits and traffic laws.

      Standard
      Condition Starter Signal
      Driving at 20 km/h (12.43 mph) or more (engine speed 1000 rpm or more) OFF

      Tech Tips

      If the result of either of the above is not as specified, proceed to the next step with the engine switch on (IG), GTS connected and Data List item "Starter Signal" selected.

      Result
      Proceed to
      OK
      NG

      Tech Tips

      If the starter assembly operates continuously when the engine switch is turned on (IG), proceed to the next step without reading the Data List item "Starter Signal".

  2. INSPECT ST NO.2 RELAY (CHECK FOR SHORT CIRCUIT)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / Starter Signal.


      Powertrain > Engine and ECT > Data List
      Tester Display
      Starter Signal

    5. Remove the ST NO.2 relay from the engine room relay block and junction block assembly.

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

      Result
      Result Proceed to
      The Data List item "Starter Signal" does not change from ON A
      The Data List item "Starter Signal" changes from ON to OFF B

      Tech Tips


      • When the result of the above inspection is "The Data List item "Starter Signal" does not change from ON", the ST NO.2 relay is normal.

      • DTCs may be stored during this inspection. Check for DTCs and clear them using the GTS.

  3. CHECK TERMINAL VOLTAGE (STA SIGNAL)

    B008ISPC01
    *1 No. 2 Engine Room Relay Block and Junction Block Assembly
    *2 ST NO.2 Relay

    Tech Tips

    The purpose of this step is to check for ST NO.2 relay terminal voltage under abnormal conditions.


    1. Remove the ST NO.2 relay from the No. 2 engine room relay block and junction block assembly.

    2. Turn the engine switch on (IG).

    3. Measure the voltage between ST NO.2 relay terminal 2 and body ground.

      Tech Tips


      • Make a note of the measured voltage as it will be necessary for the inspecting the change in voltage in the next step. As the next step should be conducted under the same conditions, keep the engine switch on (IG) and do not install the ST NO.2 relay.

      • DTCs may be stored during this inspection. Check for DTCs and clear them using the GTS.

      • If any voltage was measured with the engine switch on (IG), one of the following malfunctions is suspected:


        • Short to +B in the circuit of a connected ECU or the switch.

        • Short to +B in the wire harness.

      The voltage between ST NO.2 relay terminal 2 and body ground changes when the connector is disconnected. B

      Tech Tips


      • If the voltage is the same before and after disconnecting the connector, the engine stop and start ECU is normal.

      • DTCs may be stored during this inspection. Check for DTCs and clear them using the GTS.
