СИСТЕМА SFI (для моделей без вспомогательной системы подачи воздуха в нейтрализатор), Diagnostic DTC:P0617

DTC Code DTC Name
P0617 Starter Relay Circuit High

DESCRIPTION

While the engine is being cranked, the positive battery voltage is applied to terminal STA of the ECM. If the ECM detects the Starter Control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and stores the DTC.

This monitor runs when the vehicle is driven at 20 km/h (12.4 mph) for over 20 seconds.

DTC Code DTC Detection Condition Trouble Area
P0617

When conditions (a), (b) and (c) are met, and a positive (+B) battery voltage of 10.5 V or higher is applied to the ECM for 20 seconds (1 trip detection logic).


  • (a) The vehicle speed is 20 km/h (12.4 mph) or more.

  • (b) The engine speed is 1000 rpm or more.

  • (c) The STA signal is ON.

  • Park/Neutral Position (PNP) switch

  • Starter relay circuit

  • Engine switch

  • ECM

Tech Tips


  • The following troubleshooting flowchart is based on the premise that the engine is cranked normally.

    If the engine will not crank, proceed to the Problem Symptoms Table Click here.

  • Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. 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 INTELLIGENT TESTER (STARTER SIGNAL)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG) and turn the tester on.

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

    4. Check the value displayed on the tester when the engine switch is turned to the START positions.

      OK
      Engine Switch Position Starter Signal
      On (IG) OFF
      START ON

    OK

    OK

  3. CHECK HARNESS AND CONNECTOR (PNP SWITCH - ECM)


    1. Disconnect the C24 PNP switch connector.

    2. Disconnect the A38 ECM connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      C24-5 - A38-46 (STA) Always Below 1 Ω
      C24-5 or A38-46 (STA) - Body ground Always 10 kΩ or higher

    OK
