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. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0617 | Following conditions (a), (b) and (c) met for 20 seconds (1 trip detection logic):
|
|
*1: for Manual Transaxle
*2: for CVT
*3: w/o Entry and Start System
*4: w/ Entry and Start System

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 is cranked normally.
If the engine will not crank, proceed to the Problem Symptoms Table Click here.
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.
PROCEDURE
READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL)
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / Data List / Starter Signal.
Read the value displayed on the tester when the ignition switch is ON and the engine starts.
