Title: U660E (AUTOMATIC TRANSMISSION / TRANSAXLE): AUTOMATIC TRANSAXLE SYSTEM: P0617; Starter Relay Circuit High; 2016 MY Sienna [12/2015 - 08/2016]

DTC

P0617

Starter Relay Circuit High

DESCRIPTION

While the engine is being cranked, battery voltage is applied to terminal STA of the TCM.

If the TCM detects the Starter Control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The TCM will turn on the MIL and store the DTC.

This monitor runs when the vehicle is driven at 20 km/h (12.43 mph) for over 20 seconds.

DTC No.

DTC Detection Condition

When conditions (a), (b) and (c) are met, positive (+B) battery voltage 10.5 V or more applied to TCM for 20 seconds (1 trip detection logic).

(a) Vehicle speed more than 20 km/h (12.43 mph)

(b) Engine speed more than 1000 rpm

WIRING DIAGRAM

CAUTION / NOTICE / HINT

NOTICE:

Perform the universal trip to clear permanent DTCs (See page ).

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 (See page ).

PROCEDURE

1.	READ VALUE USING TECHSTREAM (STARTER SIGNAL)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(d) Enter the following menus: Powertrain / ECT / 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:

Switch Condition	Starter Signal
ON	OFF
START	ON

CHECK FOR INTERMITTENT PROBLEMS

2.	READ VALUE USING TECHSTREAM (STARTER SIGNAL)

(a) Turn the Techstream off.

(b) Turn the ignition switch off.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Powertrain / ECT / Data List / All Data / Starter Signal.

(g) Check the value displayed on the Techstream when the ignition switch is turned to ON.

Result

Starter Signal	Proceed to
ON	A
OFF	B

GO TO STEP 4

3.	INSPECT TCM (STA VOLTAGE)

(a) Turn the ignition switch off.

(b) Disconnect the ECM connector.

(d) Connect the park/neutral position switch connector.

(e) Disconnect the TCM connector.

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

Result

Tester Connection	Condition	Specified Condition	Proceed to
B2-10 (STA) - Body ground	Always	11 to 14 V	A
B2-10 (STA) - Body ground	Always	Below 1.5 V	B

REPAIR OR REPLACE HARNESS OR CONNECTOR (TCM - PARK/NEUTRAL POSITION SWITCH - ST RELAY AND OTHER ECUS)

REPLACE TCM

4.	INSPECT PARK/NEUTRAL POSITION SWITCH

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

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

Standard Resistance:

Tester Connection	Switch Condition (Shift Lever Position)	Specified Condition
4 (B) - 9 (L)	P	Below 1 Ω
	N	Below 1 Ω
	Except P and N	10 kΩ or higher
1 (RB) - 9 (L)	P	10 kΩ or higher
	R	10 kΩ or higher
	N	10 kΩ or higher
	D	10 kΩ or higher

Result

Result	Proceed to
Short between 4 and 9 (w/o Smart Key System)	A
Short between 4 and 9 (w/ Smart Key System)	B
Short between 1 and 9	C

GO TO STEP 9

REPLACE PARK/NEUTRAL POSITION SWITCH

5.	REPLACE PARK/NEUTRAL POSITION SWITCH

(a) Replace the park/neutral position switch (See page ).

6.	CHECK DTC OUTPUT

(a) Start the engine.

(b) Turn the Techstream on.

(d) Perform the monitor drive pattern (See page )

(e) Check the DTC output on the Techstream.

Result

Result	Proceed to
DTC not output	A
P0617 is output	B

END

7.	INSPECT IGNITION SWITCH

(a) Remove the ignition switch.

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

Standard Resistance:

Tester Connection	Switch Condition	Specified Condition
8 (ST2) - Except 7 (AM2) terminal	LOCK, ACC AND ON	10 kΩ or higher

REPLACE IGNITION SWITCH

8.	INSPECT TCM (NSW TERMINAL VOLTAGE)

(a) Reinstall the ignition switch.

(b) Turn the ignition switch off.

(d) Connect the park/neutral position switch connector.

(e) Disconnect the TCM connector.

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

Standard Voltage:

Tester Connection	Switch Condition	Specified Condition
B2-11 (NSW) - Body ground	Ignition switch off	Below 1.5 V
