ELECTRONIC CONTROLLED AUTOMATIC TRANSMISSION SYSTEM, Diagnostic DTC:P2716

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

DESCRIPTION

Refer to DTC P0894 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)

  • Open or short in shift solenoid valve SLT circuit

  • Shift solenoid valve SLT

  • ECM

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 illuminate the MIL and store the DTC.

INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLT)


    1. A01E2ZME27

      Disconnect the E1 wire connector.

    2. Measure the resistance of the wire connector.

      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 20°C (68°F) 10 kΩ or higher
      6 (SLT-) - Body ground 20°C (68°F) 10 kΩ or higher

    NG

    OK

  2. CHECK WIRE HARNESS (TRANSMISSION WIRE - ECM)


    1. A01E0X8E08

      Disconnect the E16 ECM connector.

    2. Measure the resistance of the wire harness side connector.

      Standard resistance
      Tester Connection Condition Specified Condition
      E16-13 (SLT+) - E16-12 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω
      E16-13 (SLT+) - Body ground 20°C (68°F) 10 kΩ or higher
      E16-12 (SLT-) - Body ground 20°C (68°F) 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS AND CONNECTOR

    OK

    REPLACE ECM

  3. INSPECT SHIFT SOLENOID VALVE SLT


    1. A01DWV8E16

      Remove the shift solenoid valve SLT.

    2. Measure the resistance of the solenoid valve.

      Standard resistance
      5.0 to 5.6 Ωat 20°C (68°F)

    3. 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.

    4. Check the operating noise of terminal 1 of the solenoid valve.

      OK
      Solenoid makes operating noise.

      Tech Tips

      Reference: Inspect using an oscilloscope.

      A01DXIVE03

      Check the waveform of the ECM connector.

      OK
      Refer to illustration.
