DTC P0617 Starter Relay Circuit High


DESCRIPTION

While the engine is being cranked, the 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 is driven at 20 km/h (12.4 mph) for over 20 seconds.

INSPECTION PROCEDURE

HINT:
  1. The following troubleshooting flowchart 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).
  2. 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, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
1.READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the engine switch on (IG) and turn the tester on.

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

  1. Check the value displayed on the tester when the engine switch is turned to the START positions.

    OK:

    Engine Switch Position
    		Starter Signal
    On (IG)
    		OFF
    START
    		ON

2.INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY

  1. Inspect the park/neutral position switch (Click here).



NG
REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY (Click here)
OK


3.CHECK HARNESS AND CONNECTOR (PNP SWITCH - ECM)

  1. Disconnect the C24 PNP switch connector.

  1. Disconnect the A38 ECM connector.

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

    Standard Resistance:

    Tester Connection
    		Condition
    		Specified Condition
    C24-5 - A38-46 (STA)
    		Always
    		Below 1 Ω
    C24-5 or A38-46 (STA) - Body ground
    		Always
    		10 kΩ or higher


NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK
