DTC P0617 Starter Relay Circuit High


​

DESCRIPTION

While the engine is being cranked, battery voltage is applied to terminal STA of the ECM.
If the ECM detects the starter signal (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 is driven at 20 km/h (12.4 mph) for over 20 seconds.

DTC No.

Connect to the intelligent tester to the DLC3. Camry


INSPECTION PROCEDURE

HINT:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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 to the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON.

  1. 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 vehicle is driven at 20 km/h (12 mph) or more.

    Result:

    Condition
    		Starter Signal
    		Result
    Driving at 20 km/h (12 mph) or more
    		Close (OFF)
    		A
    Open (ON) (for automatic transaxle models)
    		B
    Open (ON) (for manual transaxle models)
    		C
