 Trouble Area
P282B

  1. The vehicle is being driven.

  2. An open or short circuit in the shift solenoid valve SLS circuit is detected.

  3. 1 second or more

  4. 1-trip detection logic

  • Wire harness or connector

  • Continuously variable transaxle assembly (Shift solenoid valve SLS)

  • ECM

MONITOR DESCRIPTION

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

      *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
      5 (SLS+) - 12 (SLS-) 20°C (68°F) 5.0 to 5.6 Ω
      5 (SLS+) - Body ground and other terminals Always 10 kΩ or higher
      12 (SLS-) - Body ground and other terminals Always 10 kΩ or higher

    NG
