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

MONITOR DESCRIPTION

While the engine is being cranked, positive battery voltage is applied to terminal STA of the ECM.

If the ECM detects the starter (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) or more for over 20 seconds.





*1: Automatic transmission models.

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 operation) Reading and Clearing Diagnostic Trouble Codes.

4. Turn the engine switch off and wait for at least 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. Drive the vehicle at 15 mph (24 km/h) or more for 20 seconds or more [C].

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

11. Input the DTC: P0617.

12. Check the DTC judgment result.





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

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 UNKNOWN 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
- The following troubleshooting procedure 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 the 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 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. 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 / Starter Signal.

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

OK:

(a) Remove the ST CUT relay from the engine room relay block 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 / Starter Signal.

(f) Read the value displayed on the Techstream when the engine switch is turned on (IG).

(g) Reconnect the clutch pedal switch connector.

Result:
