P0617
2AZ-FE ENGINE CONTROL: SFI SYSTEM: P0617: Starter Relay Circuit High
P0617 - Starter Relay Circuit High
MONITOR DESCRIPTION
While the engine is being cranked, 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) for over 20 seconds.

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 procedure) 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 minutes or more [B].
7. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
8. Input the DTC: P0617.
9. Check the DTC judgment result [C].
HINT
* If the judgment result shows ABNORMAL, the system has a malfunction.
* If the judgment result shows INCOMPLETE or UNKNOWN, perform steps [D] and [E].
10. 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.
11. Check the DTC judgment result [E].
12. If the test result is UNKNOWN, enter the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.
13. Read Pending DTCs.
HINT
If a pending DTC is output, the system is malfunctioning.
14. If the test 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.
WIRING DIAGRAM
INSPECTION PROCEDURE
HINT
* The following troubleshooting flowchart is based on the premise that the engine cranks normally.
If the engine will 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 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.
PROCEDURE
1. READ VALUE 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:
C -- INSPECT CLUTCH PEDAL SWITCH
B -- INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
A -- CHECK FOR INTERMITTENT PROBLEMS Check for Intermittent Problems
2. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Inspect the park/neutral position switch assembly for 2WD, Component Tests and General Diagnostics for 4WD).
Result:
C -- REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY Components
B -- REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY
A -- 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. INSPECT CLUTCH PEDAL SWITCH
(a) Inspect the clutch pedal switch .
NG -- REPLACE CLUTCH PEDAL SWITCH
OK -- Continue to next step.
5. 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.
6. 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 Components
