AUTOMATIC TRANSAXLE 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 the DTC.

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

DTC Code DTC Detection Condition Trouble Area
P0617

All conditions are met (1-trip detection logic):

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

(b) Engine speed is more than 1000 rpm.

(c) STA signal is ON.

(d) Battery voltage (10.5 V or more) is applied to the TCM for 20 seconds.

INSPECTION PROCEDURE

Tech Tips


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

  • Read freeze frame data using the intelligent tester. 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 moving or stationary, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction Click here.

PROCEDURE


  1. READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON.

    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.

      (to TCM)

      Disconnect the TCM connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      C29-10 (STA) - Body ground Ignition switch ON and shift lever in P or N Below 2 V

    3. Turn the ignition switch off.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      C29-8 (E1) - Body ground Always Below 1 Ω

    NG

      Component without harness connected

      (Park/Neutral Position Switch)

      Disconnect the 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) - 9 (L) Shift lever in P Below 1 Ω
      4 (B) - 9 (L) Shift lever in N Below 1 Ω
      4 (B) - 9 (L) Shift lever not in P 10 kΩ or higher
      4 (B) - 9 (L) Shift lever not in N 10 kΩ or higher
      1 (RB) - 9 (L) Shift lever in P, R, N, D or M 10 kΩ or higher
