ECD SYSTEM, Diagnostic DTC:P0617

DTC Code DTC Name
P0617 Starter Relay Circuit High

DESCRIPTION

While the engine is being cranked, the Starter Control (STA) signal is also sent to terminal STA of the ECM. The STA signal is used to increase the fuel injection volume mainly when starting the engine. If the ECM detects the Starter Control (STA) signal while the vehicle is being driven, this DTC is stored.

DTC No. DTC Detection Condition Trouble Area
P0617

STA signal is being input to ECM regardless of whether vehicle is in motion

(1 trip detection logic)

  • Starter relay circuit

  • Ignition switch

  • ECM

CAUTION / NOTICE / HINT

Note


  • When replacing the ECM, the ECM needs Registration and Initialization Click here.

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

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 GTS. 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 GTS (STARTER SIGNAL)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

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

    4. Read the value displayed on the GTS when the ignition switch is turned to ON.

      OK
