CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P2769, P2770

DTC Code DTC Name
P2769 Short in Torque Converter Clutch Solenoid Circuit (Shift Solenoid Valve SL)
P2770 Open in Torque Converter Clutch Solenoid Circuit (Shift Solenoid Valve SL)

DESCRIPTION

Based on the signal received by the shift solenoid valve SL, the ECM uses the shift solenoid valve SLU to control the lock-up clutch pressure.

If there is an open or short in the shift solenoid valve SL 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 SL circuit. If there is an open or short in the shift solenoid valve SL circuit, the ECM detects the problem, illuminates the MIL and stores a DTC.

    1. A01QPFJC10
      *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
      12 (SL) - Body ground 20°C (68°F) 11 to 15 Ω
      Result
      Proceed to
      OK
      NG
