Purpose/Function

• The up switch signal is sent to the TCM via CAN and is used for manual shift control and engine-transmission 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.
