CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P2716

DESCRIPTION

The ECM uses signals to control shift solenoid valve SLT to provide optimum line pressure control. Shift solenoid valve SLT is also used during forward and reverse clutch engagement to control the oil pressure to the forward and reverse clutch.

MONITOR DESCRIPTION

This DTC indicates an open or short circuit in the shift solenoid valve SLT circuit. When there is an open or short circuit in the shift solenoid valve SLT circuit, the ECM detects the problem, illuminates the MIL and stores the DTC.

   INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLT)

   
   
   1. 

      Disconnect the transmission wire connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition 2 (SLT+) - 7 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω 2 (SLT+) - Body ground Always 10 kΩ or higher 7 (SLT-) - Body ground Always 10 kΩ or higher

   CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)

   
   
   1. 

      Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition C68-60 (SLT-) - C68-61 (SLT+) 20°C (68°F) 5.0 to 5.6 Ω C68-60 (SLT-) - Body ground Always 10 kΩ or higher C68-61 (SLT+) - Body ground Always 10 kΩ or higher

   PERFORM INITIALIZATION

   Note:
   

   • Performing reset memory will clear the learned values of both the yaw rate sensor (deceleration sensor 0 point calibration) and CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate sensor 0 point calibration and CVT oil pressure calibration when replacing any of the parts shown in the following table:

     Replaced Part
     Continuously variable transaxle assembly ECM Oil pressure sensor Yaw rate sensor

   • After performing reset memory, always perform yaw rate sensor (deceleration sensor 0 point) calibration first, and then CVT oil pressure calibration.

   • Always perform 0 point calibration with the vehicle on level ground (inclination: 0 +/-0.25°).

   • Do not shake or vibrate the vehicle during 0 point calibration.

   
   

   1. Using the intelligent tester, perform reset memory, deceleration sensor 0 point calibration and CVT oil pressure calibration (Click here).

   2. Check that no DTC is stored.
