Diagnostic Fault Information

Circuit Description

The position sensor that sets 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-volt reference and ground 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 memory seat module must be powered.

Conditions for Setting the DTC

B1825 01, B1850 01, B1860 01, B2355 01, B2365 01, B2375 01

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

DTC.

B1825 06, B1850 06, B1860 06, B2355 06, B2365 06, B2375 06

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

B1825 5A, B1850 5A, B1860 5A, B2355 5A, B2365 5A, 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.
