DTC P08BA-12: Pressure Control Solenoid "L" Circuit Short to Battery [11/2016 - 10/2017]: Description
WARNING: This page is about a different car, the 2019 Toyota Highlander, 2018 Toyota Highlander, and 2017 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
Changing gears is performed by the ECM turning the solenoid (SL1, SL2, SL3, SL4, SL5 and SL6) valves on and off.
If an open or short occurs in any of the solenoid valve circuits, the ECM controls the remaining normal solenoid valves to allow the vehicle to be driven. If all of the solenoid valves are malfunctioning, only the mechanical fluid pressure circuit will function and some manual operation will be possible. If an open or short occurs in a solenoid valve circuit, the ECM cuts power to the malfunctioning solenoid valve.
HINT:
The following table shows normal operation of the solenoid (SL6) valve when the shift lever is in D.
