DTC 24: Outward Slide Pulse Abnormal: Description

When the No. 2 power seat switch assembly (ingress and egress switch) has been operated, the position control ECU assembly outputs driving voltage to drive the power seat motor assembly (outward slide motor). When the power seat motor assembly (outward slide motor) is driven, its pulse sensor sends the seat position information via pulse signal to the position control ECU assembly. Based on this signal, the position control ECU assembly stores the seat outward slide position.
