SFI 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 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
P0617

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):


  • (a) The vehicle speed is more than 20 km/h (12.4 mph).

  • (b) The engine speed is more than 1000 rpm.

  • (c) The STA signal is on.

  • Short in cranking holding function circuit*1

  • Short in starter signal circuit*2

  • Clutch start switch assembly*3

  • Park/neutral position switch assembly*4

  • Power management control ECU*1

  • Ignition switch*2

  • ECM

INSPECTION PROCEDURE

Note

Inspect the fuses for circuits related to this system before performing the following 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 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.

PROCEDURE


  1. CHECK IF VEHICLE IS EQUIPPED WITH ENTRY AND START SYSTEM


    1. Check if the vehicle is equipped with an entry and start system.
