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 defective shift solenoid valve.

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 problem and stores a DTC.

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SC)


    1. A01QPFJC08
      *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
      10 (SC) - Body ground 20°C (68°F) 11 to 15 Ω
      Result
      Proceed to
      OK
      NG

    NG

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


    1. A01QPVYC02
      *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
      B93-41 (SC) - Body ground 20°C (68°F) 11 to 15 Ω
      Result
