| P0617 | Starter Relay Circuit High |
DESCRIPTION
with Smart Entry and Start System
The cranking holding control system keeps energizing the starter relay after the ECM detects the starter signal (STSW signal) from the main body ECU until the ECM performs a judgment of "Engine started". Furthermore, the ECM outputs an accessory cut signal (ACCR signal) to the ACC relay during cranking to prevent flickering of the combination meter, clock, audio system, and so on.
When the ECM detects the STSW signal, the ECM outputs the starter relay drive signal (STAR signal) to the starter relay through the park/neutral position switch, and then, the engine is cranked. When the ECM receives a stable engine speed signal (NE signal), more specifically, when the NE signal reaches a predetermined value, the ECM stops outputting the STAR signal. Also, the ECM monitors the starter relay operating conditions based on the STA terminal voltage status.
without Smart Entry and Start System
While the engine is being cranked, the positive battery voltage is applied to terminal STA of the ECM.
If the ECM detects the Starter Control (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.
This monitor runs when the vehicle is driven at 20 km/h (12.4 mph) for over 20 seconds.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0617 | When conditions (a), (b) and (c) met, positive (+B) battery voltage 10.5 V or more applied to ECM for 20 seconds (1 trip detection logic):

*1: Only for vehicles w/o Smart Entry and Start System.
*2: Only for vehicles w/ Smart Entry and Start System.
INSPECTION PROCEDURE
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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
PROCEDURE
READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL)
Connect to the intelligent tester to the DLC3.
Turn the ignition switch on (IG).
Turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / Data List / All Data / Starter Signal.
Check the value displayed on the tester when the vehicle is driven at 20 km/h (12 mph) or more.
