DTC P0617 Starter Relay Circuit High


DESCRIPTION

While the engine is being cranked, positive battery voltage is applied to terminal STA of the ECM. If the ECM detects the Starter Control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and stores the DTC.
This monitor runs when the vehicle is driven at 20 km/h (12.4 mph) for over 20 seconds.

DTC Code
DTC Detection Condition
Trouble Area
P0617
When conditions (a), (b) and (c) are met, and a positive (+B) battery voltage of 10.5 V or higher is applied to the ECM for 20 seconds (1 trip detection logic).
  1. (a) The vehicle speed is 20 km/h (12.4 mph) or more.
  2. (b) The engine speed is 1000 rpm or more.
  3. (c) The STA signal is on.

CONFIRMATION DRIVING PATTERN


Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25.1Gr-Fe Engine Control.Sfi System. Dtc P0617 Starter Relay Circuit High

  1. Connect the intelligent tester to the DLC3.
  2. Turn the ignition switch to ON and turn the tester on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).
  4. Turn the ignition switch off and wait for at least 30 seconds.
  5. Turn the ignition switch to ON and turn the tester on [A].
  6. Idle the engine for 5 seconds or more [B].
  7. Drive the vehicle at 24 km/h (15 mph) or more for 20 seconds or more [C].
    CAUTION:
    When performing the confirmation driving pattern, obey all speed limits and traffic laws.
  8. Enter the following menus: Powertrain / Engine and ECT / DTC [D].
  9. Read the pending DTCs.
    HINT:
    1. If a pending DTC is output, the system is malfunctioning.
    2. If a pending DTC is not output, perform the following procedure.
  10. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
  11. Input the DTC: P0617.
  12. Check the DTC judgment result.

    Tester Display
    		Description
    NORMAL
    1. DTC judgment completed
    2. System normal
    ABNORMAL
    1. DTC judgment completed
    2. System abnormal
    INCOMPLETE
    1. DTC judgment not completed
    2. Perform driving pattern after confirming DTC enabling conditions
    N/A
    1. Unable to perform DTC judgment
    2. Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit
    HINT:
    1. If the judgment result shows NORMAL, the system is normal.
    2. If the judgment result shows ABNORMAL, the system has a malfunction.
    3. If the judgment result shows INCOMPLETE or N/A, perform steps [C] and [D] again and, if necessary, extend the driving time.

INSPECTION PROCEDURE

HINT:
  1. The following troubleshooting flowchart is based on the premise that the engine is cranked normally.
    If the engine will not crank, proceed to the Problem Symptoms Table (HILUX_TGN26 RM000000PDG0R6X.html).
  2. Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
1.READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON and turn the tester on.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / Starter Signal.

  1. Check the value displayed on the tester when the vehicle is driven at 20 km/h (12.4 mph) or more with engine speed at 1000 rpm or more.
