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 stores this DTC.

This monitor runs when the vehicle is driven at 20 km/h (12.43 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 1, 2 and 3 are met, positive (+B) battery voltage 10.5 V or more applied to TCM for 20 seconds (1 trip detection logic).


  1. Vehicle speed of 20 km/h (12.43 mph) or more

  2. Engine speed more than 1000 rpm

  3. STA signal ON

  • Park/neutral position switch assembly

  • Starter relay circuit

  • Cranking holding function circuit

  • Harness and connector

  • TCM

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)

    5. Check the value displayed on the GTS when the vehicle is driven at 20 km/h (12.43 mph) or more.

      CAUTION:

      Strictly observe posted speed limits, traffic laws and road conditions when performing the road test.

    1. B002C92C80
      *a

      Component without harness connected

      (Park/Neutral Position Switch)

      Disconnect the E25 park/neutral position switch connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      4 (B) - 5 (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
      2 (RB) - 5 (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

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


    1. B002EBBC26
      *a

      Rear view of wire harness connector

      (to TCM)

      Disconnect the A28 TCM connector.

    2. Remove the ST relay from the No. 1 engine room relay block.

    3. Turn the engine switch on (IG).

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      A28-15 (STA) - Body ground Engine switch on (IG) Below 2 V
