Auto Access Seat does not Operate (Buzzer does not Sound): Description

The operation of the auto access seat is limited by each limit switch and the pulse sensor of each motor. When the power supply voltage is 10.5 V or more, and the requirements for operation have been fulfilled. Refer to OPERATION CHECK , the position control ECU assembly drives each motor and performs egress and ingress operations according to inputs from the No. 2 power seat switch assembly (ingress and egress switch). If there is a malfunction in any limit switch or the pulse sensor of any motor, the position control ECU assembly will sound the malfunction buzzer and will halt operation of the seat even when input from the No. 2 power seat switch assembly (ingress and egress switch) is received.
