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 No.	DTC Detection Condition	Trouble Area
P0617	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) Vehicle speed is 24 km/h (15 mph) or more. (b) Engine speed is 1000 rpm or more. (c) STA signal is on.	Park/neutral position switch assembly Starter relay (ST) circuit Main body ECU ECM

CONFIRMATION DRIVING PATTERN

Connect the GTS to the DLC3.

Turn the engine switch on (IG) and turn the GTS on.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).

Turn the engine switch off and wait for at least 30 seconds.

Turn the engine switch on (IG) and turn the GTS on [A].

Idle the engine for 5 seconds or more [B].

Drive the vehicle at 24 km/h (15 mph) or more for 20 seconds or more [C].

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.

Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [D].

Read the pending DTCs.

HINT:

If a pending DTC is output, the system is malfunctioning.

If a pending DTC is not output, perform the following procedure.

Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

Input the DTC: P0617.

Check the DTC judgment result.

GTS Display	Description
NORMAL	DTC judgment completed System normal
ABNORMAL	DTC judgment completed System abnormal
INCOMPLETE	DTC judgment not completed Perform driving pattern after confirming DTC enabling conditions
N/A	Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

HINT:

If the judgment result shows NORMAL, the system is normal.

If the judgment result shows ABNORMAL, the system has a malfunction.

If the judgment result shows INCOMPLETE or N/A, perform steps [C] and [D] again and, if necessary, extend the driving time.

INSPECTION PROCEDURE

HINT:

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 ().

Read freeze frame data using the GTS. 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 GTS (STARTER SIGNAL)

Connect the GTS to the DLC3.

Turn the engine switch on (IG) and turn the GTS on.

Enter the following menus: Powertrain / Engine and ECT / Data List / Starter Signal.

Check the value displayed on the GTS when the engine switch is turned on (IG) and when the engine is started.

OK:
Condition Starter Signal
Engine switch turned on (IG) OFF
Engine started ON

Go to step 2

CHECK FOR INTERMITTENT PROBLEMS ()

2.INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY

Inspect the park/neutral position switch assembly ().

REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY ()

OK

3.REPAIR OR REPLACE HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH - ECM)

NEXT

4.CHECK WHETHER DTC OUTPUT RECURS

Connect the GTS to the DLC3.

Turn the engine switch on (IG).

Turn the GTS on.

Clear DTCs ().

Drive the vehicle at more than 24 km/h (15 mph) for more than 20 seconds.

Enter the following menus: Powertrain / Engine and ECT / Trouble Code.

Read DTCs.
