ECD 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 sets the DTC.

This monitor runs when the vehicle has been driven at 20 km/h (12.4 mph) for more than 20 seconds.

DTC No. DTC Detection Condition Trouble Area
P0617

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

(a) Vehicle speed is more than 20 km/h (12.4 mph)

(b) Engine speed is more than 1000 rpm

(c) STA signal is ON

  • Starter signal circuit

  • Ignition switch assembly

  • ECM

INSPECTION PROCEDURE

Tech Tips


  • The following troubleshooting flowchart is based on the premise that the engine is 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 be helpful in determining whether the vehicle was moving or stationary, whether the engine was warmed up or not, as well as other data recorded at the time of a malfunction.

PROCEDURE


  1. READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL)


    1. Replace the normal DLC3 cable (12 V specification) for the intelligent tester with the 24 V DLC3 cable.

      Note

      Be sure to use the 24 V DLC3 cable when connecting the intelligent tester to the DLC3. Using the normal DLC3 cable (12 V specification) will cause damage to the tester.

    2. Connect the intelligent tester to the DLC3.

    3. Turn the ignition switch to ON.

    4. Turn the tester on.

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

    6. Check the value displayed on the tester when the ignition switch is turned to ON and START position.

      OK
      Ignition Switch Condition ON START
      Starter Signal OFF ON

      *1

      Component without harness connected

      (Ignition Switch Assembly)

      Disconnect the ignition switch assembly connector.

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

      Standard Resistance
      Tester Connection Ignition Switch Position Specified Condition
      All terminals LOCK 10 kΩ or higher
      9 (AM1) - 3 (ST1) START Below 1 Ω

    3. Reconnect the ignition switch assembly connector.


    NG

    REPLACE IGNITION SWITCH ASSEMBLY

    OK

  3. CHECK HARNESS AND CONNECTOR (ECM - STARTER RELAY, IGNITION SWITCH ASSEMBLY)


    1. Disconnect the starter relay connector.

    2. Disconnect the ECM connector.

    3. Disconnect the ignition switch assembly connector.

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

      Standard Resistance
      Tester Connection Ignition Switch Position Specified Condition
      S8-1 or E23-18 (STA) - Body ground Always 10 kΩ or higher
      I6-3 (ST1) or E23-18 (STA) - Body ground Always 10 kΩ or higher

    5. Reconnect the ECM connector.

    6. Reconnect the starter relay connector.

    7. Reconnect the ignition switch assembly connector.
