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

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