B2355

DTC B2355

CIRCUIT DESCRIPTION
The seat adjuster motors are equipped with potentiometer type position sensors used by the memory seat module to determine the seat position. The motor position sensors are supplied with 5-volt reference and ground circuits from the memory seat module. The position sensor signal circuits are referenced from ground within the memory seat module. The signal voltages monitored by the memory seat module range from 0.24-4.75 volts and are determined by the wiper locations on the resistors within the position sensors. The position sensor circuit voltage levels are used by the memory seat module to determine the position of the seat when storing or recalling memory position settings.

CONDITIONS FOR RUNNING THE DTC
The system voltage must be between 9.0-16.0 volts.

CONDITIONS FOR SETTING THE DTC
The memory seat module detects the position sensor signal circuit under 0.24 volts or over 4.75 volts.

ACTION TAKEN WHEN THE DTC SETS
Memory functions will be disabled as long as the fault is current.

CONDITIONS FOR CLEARING THE DTC
- The DTC will be current for as long as the fault is present.
- When the fault is no longer present the DTC will be a history status code.
- The history DTC will be cleared after 100 error free ignition cycles, or by using the scan tool clearing DTCs feature.
