Diagnostic Fault Information



Circuit/System Description



The position sensor that set this diagnostic trouble code (DTC) is either attached to the seat directional motor drive cable or directly to the motor it



monitors. It receives a 5 V reference and low reference from the memory seat module (MSM). The sensor sends a voltage signal that varies with the



movement of the seat through the signal circuit to the MSM. Then based on this voltage signal, the MSM determines the position of the seat.



Conditions for Running the DTC



The MSM must be powered.



Conditions for Setting the DTC



B1825 01, B1850 01, B2355 01, B2365 01, or B2375 01



If the MSM sees the analog input from this sensor is greater than 4.75 V, the sensor will be considered out of range and the MSM will set this DTC.



B1825 06, B1850 06, B2355 06, B2365 06, or B2375 06



If the MSM sees the analog input from this sensor is less than 0.22 V, the sensor will be considered out of range and the MSM will set this DTC.



B1825 5A, B1850 5A, B2355 5A, B2365 5A, or B2375 5A



This DTC will set, if the MSM is controlling a motor in one direction and its position sensor is tracking the motor in the opposite direction. The



sensor is either mounted or wired incorrectly, or the polarity of the motor control circuits are reversed.



Action Taken When the DTC Sets



The MSM disables the memory recall and easy exit/entry action commands of the motor monitored by the sensor. The motor will respond to



manual positioning commands.



Conditions for Clearing the DTC



* The current DTC will clear and set to history, when the MSM sees the analog input from the sensor as between 0.22 V and 4.75 V and the
