Pressure Control Solenoid "G" Circuit Open (P280713)
DESCRIPTION
Changing from 1st to 6th is performed by the ECM turning shift solenoid valves
SL1, SL2, SL3 and SL4 on and off. If an open or short circuit occurs in any of the
shift solenoid valves, the ECM controls the remaining normal shift solenoid valves
to allow the vehicle to be operated ...
AUTO LSD system
The AUTO LSD system aids traction by using the traction control system to control
engine performance and braking when one of the rear wheels begins to spin.
The system should be used only when one of the rear wheels spinning occurs in
a ditch or rough surface.
