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


DESCRIPTION

Refer to DTC P2714 (Click here).

DTC No.
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).
  1. Open or short in shift solenoid valve SLT circuit
  2. Shift solenoid valve SLT
  3. ECM
Reference (Using an oscilloscope):
Check the waveform between the terminals SLT+ and SLT- of the ECM connector

MONITOR DESCRIPTION

When an open or short in the linear 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 TRANSMISSION WIRE (SLT)


    Lexus Is250, Is220D. Gse20 Ale20.A960E Automatic Transmission.Automatic Transmission System. Dtc P2716 Pressure Control Solenoid D Electrical (Shift Solenoid Valve Slt)

  1. Disconnect the transmission wire connector from the transmission.

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

    Standard resistance:
    Tester Connection
    		Specified Condition
    20°C (68°F)
    13 (SLT+) - 5 (SLT-)
    		5.0 to 5.6 Ω

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

    Standard resistance (Check for short):
    Tester Connection
    		Specified Condition
    13 (SLT+) - Body ground
    		10 kΩ or higher
    5 (SLT-) - Body ground
    		↑


NG
Go to step 3
OK


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


    Lexus Is250, Is220D. Gse20 Ale20.A960E Automatic Transmission.Automatic Transmission System. Dtc P2716 Pressure Control Solenoid D Electrical (Shift Solenoid Valve Slt)

  1. Connect the transmission wire connector to the transmission.

  1. Disconnect the ECM connector.

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

    Standard resistance:
    Tester Connection
    		Specified Condition
    20°C (68°F)
    E4-35 (SLT+) - E4-34 (SLT-)
    		5.0 to 5.6 Ω

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

    Standard resistance (Check for short):
    Tester Connection
    		Specified Condition
    E4-35 (SLT+) - Body ground
    		10 kΩ or higher
    E4-34 (SLT-) - Body ground
    		↑


NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK

REPLACE ECM

3.INSPECT SHIFT SOLENOID VALVE SLT


    Lexus Is250, Is220D. Gse20 Ale20.A960E Automatic Transmission.Automatic Transmission System. Dtc P2716 Pressure Control Solenoid D Electrical (Shift Solenoid Valve Slt)

  1. Remove the shift solenoid valve SLT.

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

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

  1. Connect the positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.

    OK:
    The solenoid makes an operating sound.
