CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P099B, P099C

DTC Code DTC Name
P099B Shift Solenoid "G" Control Circuit Low (Shift Solenoid Valve SC)
P099C Shift Solenoid "G" Control Circuit High (Shift Solenoid Valve SC)

DESCRIPTION

Based on the signal received by the shift solenoid valve SC, the ECM uses the shift solenoid valve SLU to control the forward and reverse clutch pressure.

If there is an open or short in the shift solenoid valve SC circuit, the ECM stops sending current to the malfunctioning shift solenoid valve.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory
P099B Shift Solenoid "G" Control Circuit Low (Shift Solenoid Valve SC) While the vehicle is driven, there is a short in the shift solenoid valve SC circuit for 3 seconds (1 trip detection logic).

MONITOR DESCRIPTION

These DTCs indicate an open or short in the shift solenoid valve SC circuit. If there is an open or short in the shift solenoid valve SC circuit, the ECM detects the malfunction, illuminates the MIL and stores a DTC.

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SC)


    1. A0048QDC32
      *a

      Component without harness connected

      (Transmission Wire)

      Disconnect the B115 transmission wire connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      9 (SC) - Body ground 20°C (68°F) 11 to 15 Ω

    3. Connect the B115 transmission wire connector.

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


    1. Disconnect the B112*1 or B118*2 ECM connector.


      • *1: for LHD

      • *2: for RHD

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

      Standard Resistance (for LHD)
      Tester Connection Condition Specified Condition
      B112-41 (SC) - Body ground 20°C (68°F) 11 to 15 Ω
      Standard Resistance (for RHD)
      Tester Connection Condition Specified Condition
      B118-41 (SC) - Body ground 20°C (68°F) 11 to 15 Ω

    3. Connect the B112*1 or B118*2 ECM connector.


      • *1: for LHD

      • *2: for RHD

      Result
      Proceed to
      OK
      NG
