СИСТЕМА АВТОМАТИЧЕСКОЙ ТРАНСМИССИИ, 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 store this DTC.

This monitor runs when the vehicle is driven at 20 km/h (12.43 mph) for over 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 10.5 V or more applied to TCM for 20 seconds

(1 trip detection logic):

(a) Vehicle speed more than 20 km/h (12.43 mph)

(b) Engine speed more than 1000 rpm

(c) STA signal ON

  • Park/neutral position switch assembly

  • Starter relay circuit

  • Cranking holding function circuit

  • TCM

Tech Tips


  • The following troubleshooting flowchart is based on the premise that the engine is cranked normally. If the engine does not crank, proceed to the problem symptoms table.

  • Read freeze frame data using the GTS. The TCM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the airfuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

PROCEDURE


  1. READ VALUE USING GTS (STARTER SIGNAL)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

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


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

      Open: Starter operating

      Close: Starter not operating

    5. Crank the engine.

    6. Read the value displayed on the GTS.

      OK

  2. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY


    1. A018IBMC06
      *a

      Component without harness connected

      (Park/Neutral Position Switch Assembly)

      Disconnect the park/neutral position switch assembly connector.

    2. Measure the resistance according to the value(s) in the table below when the shift lever is moved to each position.

      Standard Resistance
      Tester Connection Condition Specified Condition
      C14-4 (B) - C14-9 (L) Shift lever in P Below 1 Ω
      Shift lever in N Below 1 Ω
      Shift lever not in P or N 10 kΩ or higher
      C14-1 (RB) - C14-9 (L) Shift lever in P 10 kΩ or higher
      Shift lever in R 10 kΩ or higher
      Shift lever in N 10 kΩ or higher
      Shift lever in D 10 kΩ or higher
      Result
      Proceed to
      OK

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


    1. A018ITDC13
      *a

      Front view of wire harness connector

      (to TCM)

      Disconnect the TCM connector.

    2. Remove the ST relay from the engine room relay block and 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
      C3-10 (STA) - Body ground Ignition switch ON Below 1 V
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. CHECK WHETHER DTC OUTPUT RECURS


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Clear the DTCs.

      Click here


      Powertrain > ECT > Clear DTCs

    5. Drive the vehicle in accordance with the driving pattern described in Confirmation Driving Pattern.

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


      Powertrain > ECT > Trouble Codes

    7. Read the DTCs.

      Result
      Result Proceed to
      DTCs are not output OK
      DTC P0617 is output NG

    OK
