ECD SYSTEM (w/ DPF), 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 has been driven at 20 km/h (12.5 mph) or more for more than 20 seconds.

P0617

INSPECTION PROCEDURE

Note


  • Inspect the fuses of circuits related to this system before performing the following inspection procedure.

  • After replacing the ECM, the new ECM needs registration Click here and initialization Click here.

  • After replacing the fuel supply pump assembly, the ECM needs initialization Click here.

  • After replacing an injector assembly, the ECM needs registration Click here.

Tech Tips


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

  • If this DTC is output, inspect the starter.

  • 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, 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
