Pattern Select Switch Snow Mode Circuit: Description

The pattern select switch makes it possible to select Normal or SNOW modes.

The cowl side junction block ECU (main body ECU RH) receives pattern select switch information, and sends it through the multiplex communication system and CAN system to each ECU.

When SNOW is selected, the operation of the throttle motor is moderated to control engine output. This helps to reduce skidding of the drive wheels, and assists with takeoff acceleration, driving straightness and turning stability.
