Engine Control - SFI System

1AR-FE ENGINE CONTROL: SFI SYSTEM: P0617: Starter Relay Circuit High

DTC 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 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 12 mph (20 km/h) or more 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).
4. Turn the ignition switch off.
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 / Utility / All Readiness.
8. Input the DTC: P0617.
9. Check the DTC judgment result [C].





CAUTION: When performing the confirmation driving pattern, obey all speed limits and traffic laws.
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].
11. Check the DTC judgment result [E].
12. If the test result is UNKNOWN, enter the following menus: Powertrain / Engine / 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 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
NOTICE: Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT: 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 ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Data List / All Data / Starter Signal.
(e) Check the value displayed on the Techstream when the ignition switch is turned to ON and START.
OK:






NG -- INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
OK -- CHECK FOR INTERMITTENT PROBLEMS
2. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Inspect the park/neutral position switch assembly .
Result:





B -- REPAIR OR REPLACE HARNESS OR CONNECTOR (STARTER SIGNAL CIRCUIT)
A -- Continue to next step.

3. REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Replace the park/neutral position switch assembly .
NEXT -- Continue to next step.

4. 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 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 -- REPAIR COMPLETED
A -- Continue to next step.

5. REPAIR OR REPLACE HARNESS OR CONNECTOR (STARTER SIGNAL CIRCUIT)
NEXT -- Continue to next step.

6. 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 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 -- REPLACE ECM
A -- REPAIR COMPLETED
