AUTOMATIC TRANSMISSION SYSTEM(for 2GR-FSE), Diagnostic DTC:P0617

DTC Code DTC Name
P0617 Starter Relay Circuit High

DESCRIPTION

While the engine is being cranked, battery voltage is applied to terminal STA of the TCM.

If the TCM detects the starter control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The TCM then illuminates the MIL and stores this DTC.

This monitor runs when the vehicle is driven at 20 km/h (12.4 mph) or more for more than 20 seconds.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory
P0617 Starter Relay Circuit High

When conditions (a), (b) and (c) are met, positive (+B) battery voltage of 10.5 V or more applied to the TCM for 20 seconds (1 trip detection logic)

(a) Vehicle speed of 20 km/h (12.4 mph) or more

(b) Engine speed of more than 1000 rpm

(c) STA signal ON

  • Park/neutral position switch assembly

  • Starter relay circuit

  • Cranking holding function circuit

  • Harness and connector

  • TCM

 Comes on DTC stored

PROCEDURE


  1. READ VALUE USING GTS (STARTER SIGNAL)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / ECT / Data List / Starter Signal.


      Powertrain > ECT > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Starter Signal Starter signal ON or OFF

      • ON: Engine is cranking

      • OFF: Engine switch on (IG)

  2. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY


    1. B003VTFC44
      *a

      Component without harness connected

      (Park/Neutral Position Switch Assembly)

      Disconnect the park/neutral position switch assembly connector.

    2. Measure the resistance of the park/neutral position switch assembly when the shift lever is moved to each position.

      Standard Resistance
      Tester Connection Shift Lever Position Specified Condition
      4 (B) - 5 (L) P Below 1 Ω
      N Below 1 Ω
      Except P and N 10 kΩ or higher
      2 (RB) - 5 (L) P 10 kΩ or higher
      R 10 kΩ or higher
      N 10 kΩ or higher
      D 10 kΩ or higher
      Result
      Proceed to
      OK

  3. CHECK HARNESS AND CONNECTOR (TCM - PARK/NEUTRAL POSITION SWITCH ASSEMBLY)


    1. A001I9YC08
      *a

      Rear view of wire harness connector

      (to TCM)

      Disconnect the A41 TCM connector.

    2. Remove the ST NO. 1 relay from the No. 2 engine room relay block and No. 2 junction block assembly.

    3. Disconnect the park/neutral position switch assembly connector.

    4. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      A41-15 (STA) - Body ground Engine switch on (IG) Below 2 V
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. CLEAR THE DTC AND RUNNING TEST


    1. Connect the GTS to the DLC3.

    2. Start the engine and turn the GTS on.

    3. Enter the following menus: Powertrain / ECT / Trouble Codes.


      Powertrain > ECT > Clear DTCs

    4. Clear the DTCs.

      Tech Tips

      Write down the currently output DTCs before clearing them.

    5. Perform the monitor drive pattern.
