DTC P0617 Starter Relay Circuit High


DESCRIPTION

While the engine is being cranked, the 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 sets the DTC.
This monitor runs when the vehicle is driven at 20 km/h (12.4 mph) for over 20 seconds.

DTC No.

INSPECTION PROCEDURE

NOTICE:
After replacing the ECM, the new ECM needs registration (Toyota Fortuner RM0000012XK04BX.html) and initialization (Toyota Fortuner RM000000TIN04NX.html).
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 (Toyota Fortuner RM0000012WF044X.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 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 ignition switch is turned to the ON and START positions.
