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 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) 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.

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 (LandCruiser RM000000PDG103X.html).
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 / All Data / Starter Signal.

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

Standard:

Condition
Display (Starter Signal)
Engine switch on (IG)
OFF
Engine is started
ON

7.CHECK HARNESS AND CONNECTOR (PNP SWITCH OR CLUTCH SWITCH ASSEMBLY - STA TERMINAL OF ECM)

for Automatic Transmission:
1. Disconnect the park/neutral position switch assembly connector.
2. Disconnect the ECM connector
3. Measure the resistance according to the value(s) in the table below.
  Standard Resistance (Check for Open):
  Tester Connection
  Condition
  Specified Condition
  C159-5 - G56-28 (STA)
  Always
  Below 1 Ω
  Standard Resistance (Check for Short):
  Tester Connection
  Condition
  Specified Condition
  C159-5 or G56-28 (STA) - Body ground
  Always
  10 kΩ or higher
4. Reconnect the park/neutral position switch assembly connector.
5. Reconnect the ECM connector.

for Manual Transmission:
1. Disconnect the clutch pedal switch connector.
2. Disconnect the ECM connector.
3. Measure the resistance according to the value(s) in the table below.
  Standard Resistance (Check for Open):
  Tester Connection
  Condition
  Specified Condition
  A40-1 - G56-10 (STA)
  Always
  Below 1 Ω
  Standard Resistance (Check for Short):
  Tester Connection
  Condition
  Specified Condition
  A40-1 or G56-10 (STA) - Body ground
  Always
  10 kΩ or higher
4. Reconnect the clutch pedal switch connector.
5. Reconnect the ECM connector.

REPLACE HARNESS OR CONNECTOR

OK

8.CHECK WHETHER DTC OUTPUT RECURS

Connect the GTS to the DLC3.

Turn the engine switch on (IG).

Turn the GTS on.

Clear the DTCs (LandCruiser RM000000PDK1DIX.html).

Drive the vehicle at more than 20 km/h (12.4 mph) for more than 20 seconds.

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

Read the DTCs.
