CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM(for 8NR-FTS), Diagnostic DTC:P099A11, P099A15

DTC Code DTC Name
P099A11 Shift Solenoid "G" Control Circuit Short to Ground
P099A15 Shift Solenoid "G" Control Circuit Short to Battery or Open

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.

PROCEDURE


  1. INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SC)


    1. A0030OTC08
      *a

      Component without harness connected

      (Transmission Wire)

      Disconnect the B185 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 B185 transmission wire connector.
