Engine Control - SFI System

2UR-GSE ENGINE CONTROL: SFI SYSTEM: P0617: Starter Relay Circuit High

DTC P0617 - Starter Relay Circuit High

DESCRIPTION

While the engine is being cranked, 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 can crank normally. If the engine can 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.

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) Enter the following menus: Powertrain / Engine / 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:






NG -- INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
OK -- REPLACE ECM
2. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY





(a) Inspect the park/neutral position switch.
(1) Disconnect the switch connector.
(2) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






(3) Reconnect the park/neutral position switch connector.
NG -- REPLACE PARK/NEUTRAL POSITION SWITCH
OK -- CHECK CRANKING HOLDING FUNCTION CIRCUIT
