AUTOMATIC TRANSMISSION SYSTEM, 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 sets the DTC.

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

DTC Code DTC Detection Condition Trouble Area
P0617

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

(1 trip detection logic)


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

  • (b) Engine speed more than 1000 rpm

  • (c) STA signal ON


  • Park/neutral position switch

  • Starter relay circuit

  • Cranking holding function circuit

  • Harness and connector

  • TCM

INSPECTION PROCEDURE

PROCEDURE


  1. READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the intelligent tester on.

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

    5. Read the value displayed on the intelligent tester.

    6. Crank the engine.

    7. Read the value displayed on the intelligent tester.

      OK
      Tester Display Condition Standard
      Starter Signal Engine switch on (IG) OFF
      Starter Signal Engine is cranking ON

    NG
    OK
  2. INSPECT PARK/NEUTRAL POSITION SWITCH


    1. A015Z3JE32

      Disconnect the park/neutral position switch connector.

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

      Standard Resistance
      Tester Connection Shift 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

    NG
    OK
  3. CHECK TCM (STA VOLTAGE)


    1. A0161TWE18

      Disconnect the TCM connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      A58-15 (STA) - Body ground Engine switch on (IG) and shift lever in P or N Below 2 V
      Engine switch on (IG) and shift lever not in P or N Below 1 V

    NG
    OK
  4. REPLACE TCM


    1. Replace the TCM Click here.


    NEXT
  5. CHECK HARNESS AND CONNECTOR (TCM - STARTER RELAY)


    1. A0161TWE18

      Disconnect the TCM connector.

    2. Remove the STARTER relay from the engine room relay block.

    3. Disconnect the park/neutral position switch connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      A58-15 (STA) - Body ground Engine switch on (IG) Below 1 V

    NG
    OK
