SFI System

1AR-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 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 (12.4 mph) or more for over 20 seconds.

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 DTCs (even if no DTCs are stored, perform the clear DTC procedure).

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. 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 / Trouble Codes [D].

9. Read 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.

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 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 / Starter Signal.

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

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 switch assembly 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 / Data List / Starter Signal.

(f) Read the value displayed on the Techstream when the ignition switch is turned to ON.

Result

(g) Reconnect the park/neutral position switch assembly connector.

B -- INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
A -- Continue to next step.

3. INSPECT ECM (STA TERMINAL VOLTAGE)

(a) Disconnect the park/neutral position switch assembly connector.

(b) Disconnect the ECM connector.

(c) Turn the ignition switch to ON.

(d) Measure the voltage according to the value(s) in the table below.

(e) Reconnect the ECM connector.

(f) Reconnect the park/neutral position switch assembly connector.

B -- REPLACE ECM Removal

A -- REPAIR OR REPLACE HARNESS OR CONNECTOR (PARK/NEUTRAL POSITION SWITCH - ST RELAY - ECM)

4. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY

(a) Disconnect the park/neutral position switch assembly connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

C -- INSPECT IGNITION SWITCH

B -- REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY Removal
A -- Continue to next step.

5. REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY

(a) Replace the park/neutral position switch assembly Removal.

NEXT -- Continue to next step.

6. INSPECT IGNITION SWITCH

(a) Inspect the ignition switch Testing and Inspection.

NG -- REPLACE IGNITION SWITCH Removal
OK -- Continue to next step.

7. INSPECT ECM (NSW TERMINAL VOLTAGE)

(a) Disconnect the park/neutral position switch assembly connector.

(b) Disconnect the ECM connector.

(c) Turn the ignition switch to ON.

(d) Measure the voltage according to the value(s) in the table below.
