DTC B2355: Driver Front Vertical Sensor Circuit Malfunction: Description

Front vertical position sensor receives 5-volt reference and ground from Memory Seat Module (MSM). Front vertical position sensor also has a signal circuit that is wired to MSM. Front vertical position sensor sends a voltage signal that varies with movement of seat through signal circuit to MSM. Then based on this voltage signal, MSM determines position of the front of the seat.

DTC B2355 will set if MSM sees input from sensor as either less than 0.25 volt or greater than 4.75 volts. DTC B2355 will not set if B1327 is set as current. When DTC is set, MSM disables memory recall and easy exit/entry action commands of motor monitored by sensor. Motor will respond to manual positioning commands only.

DTC B2355 will clear when MSM sees input from sensor between 0.25-4.75 volts during one cycle of checking MSM inputs.
