Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - AB60F AUTOMATIC TRANSMISSION / TRANSAXLE
INSPECT NO. 1 TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLT)
CHECK HARNESS AND CONNECTOR (NO. 1 TRANSMISSION WIRE - ECM)
INSPECT SHIFT SOLENOID VALVE SLT
DTC P2716 Pressure Control Solenoid "D" Electrical (Shift Solenoid Valve SLT)
DESCRIPTION
Shift solenoid valve SLT controls the transmission line pressure for smooth transmission operation based on signals from the throttle position sensor and vehicle speed sensor. The ECM adjusts the current to shift solenoid valve SLT 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 | Open or short is detected in shift solenoid valve SLT circuit for 1 second 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.

INSPECTION PROCEDURE
| 1.INSPECT NO. 1 TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLT) |
Disconnect the No. 1 transmission wire connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition 13 (SLT+) - 5 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω 13 (SLT+) - Body ground Always 10 kΩ or higher 5 (SLT-) - Body ground Always 10 kΩ or higher
| *a | Component without harness connected (No. 1 Transmission Wire) |
|
| ||||
| OK | |
| 2.CHECK HARNESS AND CONNECTOR (NO. 1 TRANSMISSION WIRE - ECM) |
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
for LHD 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 for RHD Tester Connection Condition Specified Condition C46-9 (SLT+) - C46-8 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω C46-9 (SLT+) - Body ground Always 10 kΩ or higher C46-8 (SLT-) - Body ground Always 10 kΩ or higher

| 3.INSPECT SHIFT SOLENOID VALVE SLT |
Remove 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 2Battery negative (-) → Terminal 1Valve moves and makes an operating noise
