Toyota 4Runner: Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT) (P2716)

Toyota 4Runner Service Manual / Drivetrain / A750e Automatic Transmission / Transaxle / Automatic Transmission System / Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT) (P2716)

DESCRIPTION

Refer to DTC P2714 (See page ).

DTC Code	DTC Detection Condition	Trouble Area
P2716	Open or short is detected in the shift solenoid valve SLT circuit for 1 sec. or more while driving (1-trip detection logic).	Open or short in shift solenoid valve SLT circuit Shift solenoid valve SLT ECM

MONITOR DESCRIPTION

When an open or short in the shift solenoid valve (SLT) circuit is detected, the ECM interprets this as a fault. The ECM will turn on the MIL and store the DTC.

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

PROCEDURE

1.	INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLT)

(a) Disconnect the B32 transmission wire connector.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
14 (SLT+) - 6 (SLT-)	20°C (68°F)	5.0 to 5.6 Ω
14 (SLT+) - Body ground	Always	10 kΩ or higher
6 (SLT-) - Body ground	Always	10 kΩ or higher

GO TO STEP 3

2.	CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)

(a) Disconnect the B37 ECM connector.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
B37-34 (SLT+) - B37-35 (SLT-)	20°C (68°F)	5.0 to 5.6 Ω
B37-34 (SLT+) - Body ground	Always	10 kΩ or higher
B37-35 (SLT-) - Body ground	Always	10 kΩ or higher
