DTC P2716 Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT)

DESCRIPTION

Dtc P2716 Pressure Control Solenoid D Electrical (Shift Solenoid Valve Slt). A750F AUTOMATIC TRANSMISSION / TRANSAXLE. Land Cruiser URJ200 URJ202 GRJ200 VDJ200

The shift solenoid valve SLT controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and the vehicle speed sensor. The ECM adjusts the current of the SLT solenoid valve to control the hydraulic line pressure coming from the primary regulator valve. Appropriate line pressure assures smooth shifting with varying engine outputs.

DTC Code	DTC Detection Condition	Trouble Area
P2716	An 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.

Disconnect the transmission wire connector.

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

OK

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

Disconnect the ECM connector.

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

Standard Resistance:
Tester Connection Condition Specified Condition
C45-9 (SLT+) - C45-8 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
C45-9 (SLT+) - Body ground Always 10 kΩ or higher
C45-8 (SLT-) - Body ground Always 10 kΩ or higher

3.INSPECT SHIFT SOLENOID VALVE SLT

Remove the shift solenoid valve SLT.

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

Standard Resistance:
Tester Connection Condition Specified Condition
1 - 2 20°C (68°F) 5.0 to 5.6 Ω

Apply 12 V battery voltage to the shift solenoid valve and check that the valve moves and makes an operating noise.

OK:
Measurement Condition Specified Condition
Battery positive (+) with a 21 W bulb → Terminal 2
Battery negative (-) → Terminal 1
Valve moves and makes an operating noise
