DTC P0617 Starter Relay Circuit High

DESCRIPTION

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 stores the DTC.

This monitor runs when the vehicle is driven at 20 km/h (12.4 mph) for over 20 seconds.

DTC Code	DTC Detection Condition	Trouble Area
P0617	When conditions (a), (b) and (c) are met, and 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 20 km/h (12.4 mph) or more. (b) The engine speed is 1000 rpm or more. (c) The STA signal is ON.	Park/Neutral Position (PNP) switch Starter relay circuit Engine switch ECM

INSPECTION PROCEDURE

HINT:

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 ().

Read freeze frame data using the intelligent tester. Freeze frame data records 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.

1.READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL)

Connect the intelligent tester to the DLC3.

Turn the engine switch on (IG) and 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 engine switch is turned to the START positions.

OK:
Engine Switch Position Starter Signal
On (IG) OFF
START ON

Go to step 2

OK

CHECK FOR INTERMITTENT PROBLEMS ()

2.INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY

Inspect the park/neutral position switch ().

NG

REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY ()

OK

3.CHECK HARNESS AND CONNECTOR (PNP SWITCH - ECM)

Disconnect the C24 PNP switch connector.

Disconnect the A38 ECM connector.

Measure the resistance according to the value(s) in the table below.

Standard Resistance:
Tester Connection Condition Specified Condition
C24-5 - A38-46 (STA) Always Below 1 Ω
C24-5 or A38-46 (STA) - Body ground Always 10 kΩ or higher

NG

REPAIR OR REPLACE HARNESS OR CONNECTOR

OK
