DTC    P0617    Starter Relay Circuit High

for Preparation Click here


DESCRIPTION

While the engine is being cranked, the 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 sets the DTC.

DTC No.

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 is cranked normally.
    If the engine will not crank, proceed to the Problem Symptoms Table (Click here).
  2. Read freeze frame data using the intelligent tester. Freeze frame data record 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.
