DTC P0617 Starter Relay Circuit High


DESCRIPTION

While the engine is being cranked, 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 has been driven at 20 km/h (12.5 mph) or more for more than 20 seconds.

INSPECTION PROCEDURE

NOTICE:
After replacing the ECM, the new ECM needs registration (HILUX_TGN26 RM0000012XK07FX.html) and initialization (HILUX_TGN26 RM000000TIN04CX.html).
HINT:
  1. The following troubleshooting process is based on the premise that the engine can crank normally. If the engine does not crank, proceed to Problem Symptoms Table (HILUX_TGN26 RM0000012WF073X.html).
  2. If this DTC is output, inspect the starter.
1.READ VALUE USING INTELLIGENT TESTER (STARTER SIGNAL)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON and turn the tester on.

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

  1. Read the value displayed on the tester when the ignition switch is turned to ON.

    OK:

    Ignition Switch Positions
    		Starter Signal
    ON
    		OFF
    START
    		ON

2.INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY

  1. Inspect the park/neutral position switch assembly (HILUX_TGN26 RM0000010NA02HX.html).



NG
Go to step 6
OK


3.INSPECT IGNITION SWITCH

  1. Inspect the ignition switch (HILUX_TGN26 RM0000013ZU019X.html).



NG
Go to step 7
OK


4.CHECK HARNESS AND CONNECTOR (IGNITION SWITCH - ECM)

  1. Disconnect the ignition switch connector.

  1. Disconnect the ECM connector.

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

    Standard Resistance:

    Tester Connection
    		Condition
    		Specified Condition
    G9-7 (ST2) or G39-7 (STA) - Body ground and other terminals
    		Always
    		10 kΩ or higher

  1. Reconnect the ignition switch connector.

  1. Reconnect the ECM connector.



NG
Go to step 8
OK


5.REPLACE ECM

  1. Replace the ECM (HILUX_TGN26 RM0000013Z001IX.html).



NEXT
Go to step 9

6.REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY

  1. Replace the park/neutral position switch assembly (HILUX_TGN26 RM0000010NC05IX.html).



NEXT
Go to step 9

7.REPLACE IGNITION SWITCH

  1. Replace the ignition switch (HILUX_TGN26 RM0000013XF01HX.html).



NEXT
Go to step 9

8.REPAIR OR REPLACE HARNESS OR CONNECTOR

  1. Repair or replace the harness or connector.

9.CONFIRM WHETHER DTC OUTPUT RECURS

  1. Connect the intelligent tester to the DLC3.

  1. Clear the DTCs (HILUX_TGN26 RM000000PDK12RX.html).

  1. Turn the ignition switch off.

  1. Turn the ignition switch to ON.

  1. Drive the vehicle for 25 seconds or more at a speed of 20 km/h (12.5 mph) or more and an engine speed of 1000 rpm or more.

  1. Confirm that the DTC is not output again.
