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 line 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 the system will change to a manual transmission. If an open or short has occurred, the TCM cuts power to the malfunctioning solenoid valve.
