Component Description For Automatic Transmission Oil Auxiliary Oil Pump Control Unit - GF27.19-P-4031AHE
Transmission 722.9 (except 722.930) in model 205
Location
The auxiliary oil pump transmission oil control unit is integrated into the electric auxiliary oil pump.
Task
The automatic transmission fluid auxiliary oil pump control unit controls the electric auxiliary oil pump. When the internal combustion engine is stopped, the electric auxiliary oil pump takes over the oil supply of the control and actuator part of the transmission.
Input and output signals
The auxiliary oil pump transmission oil control unit is connected over the drive CAN (CAN C1) to the fully integrated transmission control unit (Y3/8n4) and exchanges data with it.
Evaluation of input factors
The read in input factors ware evaluated by the integrated microprocessor, and then the electric auxiliary oil pump is actuated.
