DTC B2375: Driver Seat Assembly Horizontal Sensor Circuit Malfunction: Description

Horizontal position sensor receives 5-volt reference and ground from Memory Seat Module (MSM). Horizontal position sensor also has a signal circuit that is wired to MSM. Horizontal 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 horizontal position of the seat.

DTC B2375 will set if MSM sees input from sensor as either less than 0.25 volt or greater than 4.75 volts. DTC B2375 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 B2375 will clear when MSM sees input from sensor between 0.25-4.75 volts during one cycle of checking MSM inputs.
