CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P282B

DTC Code DTC Name
P282B Pressure Control Solenoid "K" Electrical (Shift Solenoid Valve SLS)

DESCRIPTION

The ECM uses shift solenoid valve SLS to control the secondary pulley pressure and belt clamping pressure according to the input shaft torque. Additionally, shift solenoid valve SLS is used to control the forward and reverse clutch hydraulic pressure when the forward and reverse clutch is engaged.

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLS)


    1. A01QUP3C09
      *a

      Component without harness connected

      (Transmission Wire)

      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
      3 (SLS+) - 8 (SLS-) 20°C (68°F) 5.1 to 5.5 Ω
      3 (SLS+) - Body ground Always 10 kΩ or higher
      8 (SLS-) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

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


    1. A01QP1NC18
      *a

      Front view of wire harness connector

      (to ECM)

      Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      B75-73 (SLS+) - B75-72 (SLS-) 20°C (68°F) 5.0 to 5.6 Ω
      B75-73 (SLS+) - Body ground Always 10 kΩ or higher
      B75-72 (SLS-) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG
