P0617

2ZR-FE ENGINE CONTROL: SFI SYSTEM: P0617: Starter Relay Circuit High

DTC P0617 - Starter Relay Circuit High

DESCRIPTION

While the engine is being cranked, battery voltage is applied to terminal STA of the ECM.
If the ECM detects the starter signal (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 12.4 mph (20 km/h) for over 20 seconds.

- *2: Manual transaxle models.

INSPECTION PROCEDURE
HINT: Read freeze frame data using the Techstream. Freeze frame data record 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. PERFORM ACTIVE TEST USING TECHSTREAM (STARTER SIGNAL)
(a) Connect to the Techstream 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 ignition switch is turned to the ON and START positions.
OK:






Result:






C -- READ VALUE USING TECHSTREAM (STARTER SIGNAL)
B -- READ VALUE USING TECHSTREAM (STARTER SIGNAL)
A -- CHECK FOR INTERMITTENT PROBLEMS
2. READ VALUE USING TECHSTREAM (STARTER SIGNAL)




(a) Disconnect the park/neutral position 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 / 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.
B -- REPLACE PARK/NEUTRAL POSITION SWITCH
A -- Continue to next step.
3. INSPECT ECM (STA TERMINAL VOLTAGE)




(a) Disconnect the ECM connector.




(b) Disconnect the park/neutral position switch connector.
(c) Turn the ignition switch to ON.
(d) Measure the voltage according to the value(s) in the table below.
Result:





(e) Reconnect the park/neutral position switch connector.
(f) Reconnect the ECM connector.
B -- REPLACE ECM
A -- REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - PARK/NEUTRAL POSITION SWITCH - ST RELAY)
4. READ VALUE USING TECHSTREAM (STARTER SIGNAL)




(a) Disconnect the clutch pedal 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 / Starter Signal.
(f) Read the value displayed on the Techstream when the ignition switch is turned to ON.
Result:





(g) Reconnect the clutch pedal switch connector.
B -- INSPECT IGNITION SWITCH ASSEMBLY
A -- Continue to next step.
5. INSPECT ECM (STA TERMINAL VOLTAGE)




(a) Disconnect the ECM connector.




(b) Disconnect the clutch pedal switch connector.
(c) Turn the ignition switch to ON.
(d) Measure the voltage according to the value(s) in the table below.
Result:





(e) Reconnect the clutch pedal switch connector.
(f) Reconnect the ECM connector.
B -- REPLACE ECM
A -- REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - CLUTCH PEDAL SWITCH - ST RELAY)
6. INSPECT IGNITION SWITCH ASSEMBLY
(a) Inspect the ignition switch assembly Ignition Switch.
NG -- REPLACE IGNITION SWITCH ASSEMBLY
OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR (CLUTCH PEDAL SWITCH - IGNITION SWITCH ASSEMBLY - ECM)
