DTC P0617 Starter Relay Circuit High


DESCRIPTION

While the engine is being cranked, battery voltage is applied to terminal STA of the ECM.
If the ECM detects the starter signal (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.

DTC No.
DTC Detection Condition
Trouble Area

When conditions (a), (b) and (c) are met, 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 more than 20 km/h (12.4 mph).
  2. (b) The engine speed is more than 1000 rpm.
  3. (c) The STA signal is on.

INSPECTION PROCEDURE

NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT:
  1. The following troubleshooting flowchart is based on the premise that the engine can be cranked normally.
    If the engine does not crank, proceed to Problem Symptoms Table (HILUX_TGN26 RM000003S3U03JX.html).
  2. Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, 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. Read the value displayed on the tester when the ignition switch is turned to ON and when the engine is started.

    OK:
