DTC P0748: Pressure Control Solenoid "A" Electrical (Shift Solenoid Valve SL1); DTC P0778: Pressure Control Solenoid "B" Electrical (Shift Solenoid Valve SL2); DTC P0798: Pressure Control Solenoid "C" Electrical (Shift Solenoid Valve SL3); DTC P2810: Pressure Control Solenoid "G" Electrical (Shift Solenoid Valve SL4); DTC P2819: Pressure Control Solenoid "H" Electrical (Shift Solenoid Valve SL5): Description

Based on the ON-OFF combinations of the shift solenoid valves SL1, 2, 3, 4 and 5, the TCM performs gear shifts from 1st gear to 8th gear

If a circuit related to a solenoid valve is open or shorted, the TCM uses the fail-safe function to turn other solenoid valves ON or OFF. If all solenoid valves are malfunctioning, only the mechanical fluid pressure circuit will function and some manual operation will be possible If an open or short has occurred, the TCM cuts power to the malfunctioning solenoid valve
