Purpose/Function
The up switch detects the shift up operation of the selector lever.
The up switch signal is sent to the TCM via CAN and is used for manual shift control and engine-transaxle integration control.
Construction
The up switch is installed to the selector lever.
The up switch is an on/off type switch.

Operation
When the selector lever is in the shift up position (+), the up switch contact point closes.
Based on the opening and closing of the up switch contact point, the TCM detects that the shift up has been operated.
