ECD SYSTEM (w/ EGR Cooler Bypass Valve), 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 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 1,000 rpm

(c) STA signal is on

  • Starter relay circuit

  • Ignition switch lock cylinder assembly

  • ECM

INSPECTION PROCEDURE

Note


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

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

Tech Tips


  • The following troubleshooting process is based on the premise that the engine is cranked normally. If the engine will not crank, proceed to the problem symptoms table Click here.

  • Read freeze frame data using an intelligent tester. Freeze frame data records the engine condition when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, 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 ignition switch to ON and turn the tester on.

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

    4. Read values.

  6. CHECK WHETHER DTC OUTPUT RECURS


    1. Connect the intelligent tester to the DLC3.

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

    3. Clear DTCs Click here.

    4. Drive the vehicle at more than 12.4 mph (20 km/h) for over 20 seconds.

    5. Select the following menus: Powertrain / Engine and ECT / Data List / DTC.

    6. Read DTCs.
