Circuit / System Description
The seat and lumbar motors are equipped with position sensors internal to the motor. The sensors are monitored by the memory seat module (MSM) and are used to determine seat positions when storing or recalling memory settings. The seat front vertical and rear vertical motors use 3?wire hall effect type position sensors while the seat horizontal and recline motors use 2?wire hall effect type position sensors. The MSM supplies the 3?wire hall effect position sensors with a separate 5 V reference circuit and signal circuit while ground is provided at G304. The MSM supplies the 2?wire hall effect position sensors with a signal circuit while ground is also provided at G304. During seat motor operation, the hall effect position sensor provides a determined number of pulse signals for every revolution of the motor shaft. These pulse signals (Steps) range from 0?-?65,535. High scan tool step values indicate forward or upward seat positions while low step values indicate rearward or downward seat positions.
