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):

|
*1: for Manual Transmission
*2: for Automatic Transmission

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 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
CHECK IF VEHICLE IS EQUIPPED WITH ENTRY AND START SYSTEM
Confirm the entry and start system.
