Engine Control System - SFI System

2GR-FSE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0617: Starter Relay Circuit High

DTC 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 sets the DTC.
This monitor runs when the vehicle is driven at 12.4 mph (20 km/h) for over 20 seconds.

INSPECTION PROCEDURE
HINT:
- The following troubleshooting flowchart is based on the premise that the engine is cranked normally. If the engine does 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 Freeze Frame Data.

PROCEDURE

1. READ VALUE USING TECHSTREAM (STARTER SIGNAL)
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG) and turn the Techstream on.
(c) Select the following menu items: Powertrain / Engine and ECT / Data List / Starter Signal.
(d) Check the value displayed on the Techstream when the engine switch is turned on (IG) and the engine is started.

OK





OK -- REPLACE ECM
NG -- Continue to next step.
2. INSPECT PARK / NEUTRAL POSITION SWITCH ASSEMBLY





(a) Inspect the Park/Neutral Position (PNP) switch.
(1) Disconnect the E77 switch connector.
(2) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPLACE PARK / NEUTRAL POSITION SWITCH (THEN CHECK CRANKING HOLDING FUNCTION CIRCUIT)
OK -- CHECK CRANKING HOLDING FUNCTION CIRCUIT
