AUTOMATIC TRANSMISSION SYSTEM, Diagnostic DTC:P0617

DTC Code DTC Name
P0617 Starter Relay Circuit High

DESCRIPTION

While the engine is being cranked, the positive 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 12.4 mph (20 km/h) for over 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 more is applied to TCM for 20 seconds

(1 trip detection logic)


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

  • (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

PROCEDURE


  1. READ VALUE USING DATA LIST (STARTER SIGNAL)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG) and turn the intelligent tester ON.

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

    4. Read the value displayed on the tester.

    5. Crank the engine.

    6. Read the value displayed on the tester.

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

    NG

    OK

  2. CHECK TCM (STA VOLTAGE)


    1. A001DUGE01
      *1 TCM Connector

      Disconnect the A12 and E5 TCM connectors.

    2. Measure the voltage of the wire harness side connectors.

      Standard voltage
      Tester Connection Condition Specified Condition
      A12-3 (STA) - E5-7 (E1) Engine switch on (IG) and shift lever in P or N Below 2 V

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR (TCM - ST/IGCT RELAY)

    OK

  3. REPLACE TCM

  4. INSPECT PARK/NEUTRAL POSITION SWITCH


    1. A001BFXE80
      *1 Component without harness connected: (Park / Neutral Position Switch)

      Disconnect the E60 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 Condition Specified Condition
      4 (B) - 5 (L) Shift lever position P Below 1 Ω
      4 (B) - 5 (L) Shift lever position N Below 1 Ω
