SFI SYSTEM, Diagnostic DTC:P0617

DTC Code DTC Name
P0617 Starter Relay Circuit High

DESCRIPTION

While the engine is being cranked, 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 No. DTC Detection Condition Trouble Area
P0617

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


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

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

  • (c) The STA signal is ON.

  • Short in starter signal circuit

  • ECM

  • Power management control ECU

INSPECTION PROCEDURE

Tech Tips


  • The following troubleshooting flowchart is based on the premise that the engine can be cranked normally. If the engine does not crank, proceed to the Problem Symptoms Table Click here.

  • Read freeze frame data using the intelligent tester. 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, 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 / Starter Signal.

    4. Read the value displayed on the tester when the engine switch is turned on (IG).

      OK
      Switch Condition Starter Signal
      Engine switch on (IG) OFF

    3. Disconnect the D76 power management control ECU connector.

    4. Remove the ST relay from the No. 1 relay block.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      A40-48 (STA) or B14-5 - Body ground Always 10 kΩ or higher

    6. Reconnect the ECM connector.

    7. Reconnect the park/neutral position switch connector.

    8. Reconnect the power management control ECU connector.

    9. Reinstall the ST relay.

    2. Disconnect the B14 park/neutral position switch connector.

    3. Disconnect the B39 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      B14-4 or D76-3 (STAR) - Body ground Always 10 kΩ or higher

    5. Reconnect the power management control ECU connector.

    6. Reconnect the park/neutral position switch connector.

    7. Reconnect the ECM connector.
