P0617
1UR-FE ENGINE CONTROL: SFI SYSTEM: P0617: Starter Relay Circuit High
P0617 - Starter Relay Circuit High
DESCRIPTION
While the engine is being cranked, the 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 (12.43 mph) or more for over 20 seconds.

TYPICAL ENABLING CONDITIONS
TYPICAL MALFUNCTION THRESHOLDS
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 24 km/h (15 mph) 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 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.

INSPECTION PROCEDURE
NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT
* The following troubleshooting flowchart is based on the premise that the engine can be cranked normally.
If the engine will not crank, proceed to the Problem Symptoms Table Symptom Related Diagnostic Procedures.
* Read freeze frame data using the Techstream. 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.
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 / All Data / Starter Signal.
(e) Check the value displayed on the Techstream when the ignition switch is turned to the ON and START positions.
OK:
NG -- READ VALUE USING TECHSTREAM (STARTER SIGNAL)
OK -- CHECK FOR INTERMITTENT PROBLEMS Check for Intermittent Problems
2. READ VALUE USING TECHSTREAM (STARTER SIGNAL)
(a) Disconnect the Park/Neutral Position (PNP) switch connector.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON.
(d) Turn the Techstream on.
(e) Enter the following menus: Powertrain / Engine and ECT / Data List / All Data / Starter Signal.
(f) Check the value displayed on the Techstream when the ignition switch is turned to the ON and START positions.
Result
B -- INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
A -- Continue to next step.
3. INSPECT ECM (STA TERMINAL VOLTAGE)
(a) Disconnect the ECM connector.
(b) Disconnect the PNP switch connector.
(c) Turn the ignition switch to ON.
(d) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
B -- REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - PNP SWITCH - ST RELAY)
A -- REPLACE ECM Removal
4. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Disconnect the PNP switch connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

Result
C -- INSPECT IGNITION SWITCH ASSEMBLY
B -- REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY
A -- Continue to next step.
5. REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Replace the park/neutral position switch.
* for 2WD
* for 4WD Removal
NEXT -- Continue to next step.
6. INSPECT IGNITION SWITCH ASSEMBLY
(a) Disconnect the ignition switch connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

NG -- REPLACE IGNITION SWITCH ASSEMBLY Removal
OK -- Continue to next step.
7. 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 / All Data / Starter Signal.
(e) Check the value displayed on the Techstream when the ignition switch is turned to the ON and START positions.
OK:
Result
B -- CHECK FOR INTERMITTENT PROBLEMS Check for Intermittent Problems
A -- Continue to next step.
8. REPAIR OR REPLACE HARNESS OR CONNECTOR (PNP SWITCH - STA TERMINAL OF ECM)
NEXT -- Continue to next step.
9. CHECK WHETHER DTC OUTPUT RECURS
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Clear DTCs Reading and Clearing Diagnostic Trouble Codes.
(e) Drive the vehicle at more than 20 km/h (12.43 mph) for over 20 seconds.
