DTC 42: Front-rear Slide Origin Point Limit Switch Malfunction: Description

When the power seat switch assembly (front-rear slide switch) or the No. 2 power seat switch assembly (front-rear slide switch) has been operated, the position control ECU assembly outputs driving voltage to drive the power seat motor assembly (front-rear slide motor).
