ECD SYSTEM(w/ Urea SCR System), Diagnostic DTC:P0617

DTC Code DTC Name
P0617 Starter Relay Circuit High

DESCRIPTION

While the engine is being cranked, the ECM detects the starter signal (STA signal) and performs engine control when the engine starts.

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.

CAUTION / NOTICE / HINT

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.

  • Read Starter Count before replacing the engine stop and start ECU, perform the replacement procedure, and then write Starter Count to the newly installed engine stop and start ECU.

  • When replacing the engine stop and start ECU or the air conditioning amplifier assembly, initialize and learn the engine stop and start ECU air conditioning information.

  • When replacing the engine stop and start ECU or airbag ECU assembly (G sensor), initialize and learn the engine stop and start ECU G sensor zero point learned information.

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 assembly.

  • 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 / Data List / Starter Signal.


      Powertrain > Engine > Data List
      Tester Display
      Starter Signal

    4. Read the value displayed on the GTS when the vehicle is driven at 20 km/h (12.4 mph) or more with engine speed at 1000 rpm or more.
