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 (12.4 mph) or more for more than 20 seconds.

DTC No. DTC Detection Condition Trouble Area
P0617

When conditions (a), (b) and (c) are met, positive (+B) battery voltage of 10.5 V or higher is 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 or connector

  • TCM

    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
      4 (B) - 5 (L) Shift lever in N Below 1 Ω
      4 (B) - 5 (L) Shift lever not in P or N 10 kΩ or higher
      2 (RB) - 5 (L) Shift lever in P 10 kΩ or higher
      2 (RB) - 5 (L) Shift lever in R 10 kΩ or higher
      2 (RB) - 5 (L) Shift lever in N 10 kΩ or higher
      2 (RB) - 5 (L) Shift lever in D 10 kΩ or higher

    NG

      Rear view of wire harness connector

      (to TCM)

      Disconnect the TCM connector.

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

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

    4. Turn the engine switch on (IG).

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      A74-15 (STA) - Body ground Engine switch on (IG) Below 2 V

    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.

    4. Clear the DTCs.

      Tech Tips

      Write down the currently output DTCs before clearing them.

    5. Perform the monitor drive pattern Click here.

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

    7. Read the DTCs using the GTS.

      OK
      No DTC code output.
