P0617

2ZR-FE ENGINE CONTROL: 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 signal (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.





- *: Automatic transaxle models.

CONFIRMATION DRIVING PATTERN





1. Connect the Techstream to the DLC3.

2. Turn the ignition switch to ON and turn the Techstream on.

3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation) Reading and Clearing Diagnostic Trouble Codes.

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

5. Turn the ignition switch to ON and turn the Techstream on [A].

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

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

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

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

9. 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.

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

11. Input the DTC: P0617.

12. Check the DTC judgment result.





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

13. If the judgment result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs Reading and Clearing Diagnostic Trouble Codes.

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

INSPECTION PROCEDURE

HINT
Read freeze frame data using the Techstream. Freeze frame data record 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.

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM (STARTER SIGNAL)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

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

(e) Read the value displayed on the Techstream when the vehicle is driven at 12 mph (20 km/h) or more.

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

Result:





B -- INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY

C -- REPAIR OR REPLACE HARNESS OR CONNECTOR (STA SIGNAL CIRCUIT)

A -- CHECK FOR INTERMITTENT PROBLEMS Check for Intermittent Problems

2. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY

(a) Inspect the park/neutral position switch assembly Component Tests and General Diagnostics.

NG -- REPLACE PARK/NEUTRAL POSITION SWITCH Removal
OK -- Continue to next step.

3. REPAIR OR REPLACE HARNESS OR CONNECTOR (STA SIGNAL CIRCUIT)

(a) Repair or replace harness or connector (park/neutral position switch assembly - ST relay - ECM).

NEXT -- CHECK WHETHER DTC OUTPUT RECURS (DTC P0617)

4. REPAIR OR REPLACE HARNESS OR CONNECTOR (STA SIGNAL CIRCUIT)

(a) Repair or replace harness or connector (clutch pedal switch - ST relay - ECM)

NEXT -- Continue to next step.

5. CHECK WHETHER DTC OUTPUT RECURS (DTC P0617)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

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

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

(g) Read the DTCs.

Result:





B -- END

A -- REPLACE ECM Removal
