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 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): (a) Vehicle speed more than 20 km/h (12.4 mph) (b) Engine speed more than 1,000 rpm (c) STA signal ON	Park/Neutral Position (PNP) switch (A/T) or clutch start switch (M/T) PNP switch (A/T) or clutch start switch (M/T) Cranking holding function circuit ECM

Inspection procedure

HINT:

1. 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 .
2. Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, 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 OF INTELLIGENT TESTER (STARTER SIGNAL)

1. Connect the intelligent tester to the DLC3.

2. Turn the engine switch on (IG) and turn the tester ON.

3. Enter the following menus: Power train / Engine / Data List / Starter Signal.

4. Check the value displayed on the tester when the engine switch is turned to the ON and START positions.

   OK:

   Engine Switch Condition	ON	START
   STARTER SIG	OFF	ON

OK	REPLACE ECM

NG

2.INSPECT PARK / NEUTRAL POSITION SWITCH (A/T) OR CLUTCH SWITCH ASSEMBLY (M/T)

1. Inspect the Park/Neutral Position (PNP) switch (A/T) or clutch switch (M/T).

   1. Disconnect the E45*1, A24*2 switch connector.

      HINT:

      *1: A/T

      *2: M/T

   2. Measure the resistance of the switch connector.

      Standard resistance (A/T):

      Gear Selector Lever Position	Tester Connection	Specified Condition
      P	4 - 5	Below 1 ?
      N	4 - 5	Below 1 ?

      Standard resistance (M/T):

      Clutch Pedal Operation	Tester Connection	Specified Condition
      Depressed	1 - 2	Below 1 ?

   3. Reconnect the switch connector.

NG	REPLACE PARK / NEUTRAL POSITION SWITCH (A/T) OR CLUTCH SWITCH ASSEMBLY (M/T) (THEN CHECK CRANKING HOLDING FUNCTION CIRCUIT)

OK
CHECK CRANKING HOLDING FUNCTION CIRCUIT
