4GR-FSE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0617: Starter Relay Circuit High
P0617 - Starter Relay Circuit High

DESCRIPTION

While the engine is being cranked, 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 sets the DTC.

This monitor runs when the vehicle is driven at 12.43 mph (20 km/h) for over 20 seconds.

TYPICAL MALFUNCTION THRESHOLDS





CONFIRMATION DRIVING PATTERN





1. Connect the Techstream to the DLC3.

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

3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) DTC Check / Clear.

4. Turn the engine switch off and wait for 30 seconds.

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

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

7. Enter the following menus: Powertrain / Engine / Trouble Codes.

8. Read the pending DTC [C].

HINT
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.

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

10. Input the DTC: P0617.

11. Check the DTC judgment result.





HINT
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows INCOMPLETE or UNKNOWN, perform steps [D] and [E].

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

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

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

14. Check the DTC judgment result [E].

HINT
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows NORMAL, the system is normal.

15. If the test result is INCOMPLETE or UNKNOWN and no DTC is output, perform a universal trip and check for permanent DTCs DTC Check / Clear.

HINT
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE

HINT
- The following troubleshooting flowchart is based on the premise that the engine is cranked normally. If the engine does not crank, proceed to the problem symptoms table Symptom Related Diagnostic Procedures.
- Read freeze frame data using Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air/fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction Freeze Frame Data.

PROCEDURE

1. READ VALUE USING TECHSTREAM (STARTER SIGNAL)

(a) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / Engine / Data List / All Data / Starter Signal.

(e) Read the value displayed on the Techstream when the engine switch is turned on (IG) and the engine is started.

OK:

(b) Turn the engine switch on (IG).

(c) Turn the Techstream on.

(d) Clear the DTCs DTC Check / Clear.

(e) Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.

(f) Enter the following menus: Powertrain / Engine / Trouble Codes.

(g) Read the DTCs.

Result:





B -- END

A -- REPLACE ECM Removal

7. INSPECT RELAY (ST CUT RELAY)

(a) Remove the ST CUT relay from the engine room R/B No. 2.





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

Standard Resistance:





(c) Reinstall the ST CUT relay.

NG -- REPLACE RELAY (ST CUT RELAY)
OK -- Continue to next step.

8. READ VALUE USING TECHSTREAM (STA SIGNAL VOLTAGE)

(a) Disconnect the clutch pedal switch connector.





(b) Connect the Techstream to the DLC3.

(c) Turn the engine switch on (IG).

(d) Turn the Techstream on.

(e) Enter the following menus: Powertrain / Engine / Data List / All Data / Starter Signal.
